I Saw the AI Future of Video Games: It Starts With a Character Hopping Over a Box
At the 2025 Game Developers Conference, graphics-chip maker Nvidia showed off its latest tools that use generative AI to augment future games.
At its own GTC AI show in San Jose, California, earlier this month, graphics-chip maker Nvidia unveiled a plethora of partnerships and announcements for its generative AI products and platforms. At the same time, in San Francisco, Nvidia held behind-closed-doors showcases alongside the Game Developers Conference to show game-makers and media how its generative AI technology could augment the video games of the future.Â
Last year, Nvidia’s GDC 2024 showcase had hands-on demonstrations where I was able to speak with AI-powered nonplayable characters, or NPCs, in pseudo-conversations. They replied to things I typed out, with reasonably contextual responses (though not quite as natural as scripted ones). AI also radically modernized old games for a contemporary graphics look.Â
This year, at GDC 2025, Nvidia once again invited industry members and press into a hotel room near the Moscone Center, where the convention was held. In a large room ringed with computer rigs packed with its latest GeForce 5070, 5080 and 5090 GPUs, the company showed off more ways gamers could see generative AI remastering old games, offering new options for animators, and evolving NPC interactions.Â
Nvidia also demonstrated how its latest AI graphics rendering tech, DLSS 4 for its GPU line, improves image quality, light path and framerates in modern games, features that affect gamers every day, though these efforts by Nvidia are more conventional than its other experiments. While some of these advancements rely on studios to implement new tech into their games, others are available right now for gamers to try.
Making animations from text prompts
Nvidia detailed a new tool that generates character model animations based on text prompts — sort of like if you could use ChatGPT in iMovie to make your game’s characters move around in scripted action. The goal? Save developers time. Using the tool could turn programming a several-hour sequence into a several-minute task.
Body Motion, as the tool is called, can be plugged into many digital content creation platforms; Nvidia Senior Product Manager John Malaska, who ran my demo, used Autodesk Maya. To start the demonstration, Malaska set up a sample situation in which he wanted one character to hop over a box, land and move forward. On the timeline for the scene, he selected the moment for each of those three actions and wrote text prompts to have the software generate the animation. Then it was time to tinker.
To refine his animation, he used Body Motion to generate four different variations of the character hopping and chose the one he wanted. (All animations are generated from licensed motion capture data, Malaska said.) Then he specified where exactly he wanted the character to land, and then selected where he wanted them to end up. Body Motion simulated all the frames in between those carefully selected motion pivot points, and boom: animation segment achieved.
In the next section of the demo, Malaska had the same character walking through a fountain to get to a set of stairs. He could edit with text prompts and timeline markers to have the character sneak around and circumvent the courtyard fixtures.Â
“We’re excited about this,” Malaska said. “It’s really going to help people speed up and accelerate workflows.”
He pointed to situations where a developer may get an animation but want it to run slightly differently and send it back to the animators for edits. A far more time-consuming scenario would be if the animations had been based on actual motion capture, and if the game required such fidelity, getting mocap actors back to record could take days, weeks or months. Tweaking animations with Body Motion based on a library of motion capture data can circumvent all that.
I’d be remiss not to worry for motion capture artists and whether Body Motion could be used to circumvent their work in part or in whole. Generously, this tool could be put to good use making animatics and virtually storyboarding sequences before bringing in professional artists to motion capture finalized scenes. But like any tool, it all depends on who’s using it.
Body Motion is scheduled to be released later in 2025 under the Nvidia Enterprise License.
Another stab at remastering Half-Life 2 using RTX Remix
At last year’s GDC, I’d seen some remastering of Half-Life 2 with Nvidia’s platform for modders, RTX Remix, which is meant to breathe new life into old games. Nvidia’s latest stab at reviving Valve’s classic game was released to the public as a free demo, which gamers can download on Steam to check out for themselves. What I saw of it in Nvidia’s press room was ultimately a tech demo (and not the full game), but it still shows off what RTX Remix can do to update old games to meet modern graphics expectations.
Last year’s RTX Remix Half-Life 2 demonstration was about seeing how old, flat wall textures could be updated with depth effects to, say, make them look like grouted cobblestone, and that’s present here too. When looking at a wall, “the bricks seem to jut out because they use parallax occlusion mapping,” said Nyle Usmani, senior product manager of RTX Remix, who led the demo. But this year’s demo was more about lighting interaction — even to the point of simulating the shadow passing through the glass covering the dial of a gas meter.
Usmani walked me through all the lighting and fire effects, which modernized some of the more iconically haunting parts of Half-Life 2’s fallen Ravenholm area. But the most striking application was in an area where the iconic headcrab enemies attack, when Usmani paused and pointed out how backlight was filtering through the fleshy parts of the grotesque pseudo-zombies, which made them glow a translucent red, much like what happens when you put a finger in front of a flashlight. Coinciding with GDC, Nvidia released this effect, called subsurface scattering, in a software development kit so game developers can start using it.
RTX Remix has other tricks that Usmani pointed out, like a new neural shader for the latest version of the platform — the one in the Half-Life 2 demo. Essentially, he explained, a bunch of neural networks train live on the game data as you play, and tailor the indirect lighting to what the player sees, making areas lit more like they’d be in real life. In an example, he swapped between old and new RTX Remix versions, showing, in the new version, light properly filtering through the broken rafters of a garage. Better still, it bumped the frames per second to 100, up from 87.
“Traditionally, we would trace a ray and bounce it many times to illuminate a room,” Usmani said. “Now we trace a ray and bounce it only two to three times and then we terminate it, and the AI infers a multitude of bounces after. Over enough frames, it’s almost like it’s calculating an infinite amount of bounces, so we’re able to get more accuracy because it’s tracing less rays [and getting] more performance.”
Still, I was seeing the demo on an RTX 5070 GPU, which retails for $550, and the demo requires at least an RTX 3060 Ti, so owners of graphics cards older than that are out of luck. “That’s purely because path tracing is very expensive — I mean, it’s the future, basically the cutting edge, and it’s the most advanced path tracing,” Usmani said.
Nvidia ACE uses AI to help NPCs think
Last year’s NPC AI station demonstrated how nonplayer characters can uniquely respond to the player, but this year’s Nvidia ACE tech showed how players can suggest new thoughts for NPCs that’ll change their behavior and the lives around them.Â
The GPU maker demonstrated the tech as plugged into InZoi, a Sims-like game where players care for NPCs with their own behaviors. But with an upcoming update, players can toggle on Smart Zoi, which uses Nvidia ACE to insert thoughts directly into the minds of the Zois (characters) they oversee… and then watch them react accordingly. These thoughts can’t go against their own traits, explained Nvidia Geforce Tech Marketing Analyst Wynne Riawan, so they’ll send the Zoi in directions that make sense.
“So, by encouraging them, for example, ‘I want to make people’s day feel better,” it’ll encourage them to talk to more Zois around them,” Riawan said. “Try is the key word: They do still fail. They’re just like humans.”
Riawan inserted a thought into the Zoi’s head: “What if I’m just an AI in a simulation?” The poor Zoi freaked out but still ran to the public bathroom to brush her teeth, which fit her traits of, apparently, being really into dental hygiene.Â
Those NPC actions following up on player-inserted thoughts are powered by a small language model with half a billion parameters (large language models can go from 1 billion to over 30 billion parameters, with higher giving more opportunity for nuanced responses). The one used in-game is based on the 8 billion parameter Mistral NeMo Minitron model shrunken down to be able to be used by older and less powerful GPUs.Â
“We do purposely squish down the model to a smaller model so that it’s accessible to more people,” Riawan said.Â
The Nvidia ACE tech runs on-device using computer GPUs — Krafton, the publisher behind InZoi, recommends a minimum GPU spec of an Nvidia RTX 3060 with 8GB of virtual memory to use this feature, Riawan said. Krafton gave Nvidia a “budget” of one gigabyte of VRAM in order to ensure the graphics card has enough resources to render, well, the graphics. Hence the need to minimize the parameters.Â
Nvidia is still internally discussing how or whether to unlock the ability to use larger-parameter language models if players have more powerful GPUs. Players may be able to see the difference, as the NPCs “do react more dynamically as they react better to your surroundings with a bigger model,” Riawan said. “Right now, with this, the emphasis is mostly on their thoughts and feelings.”
An early access version of the Smart Zoi feature will go out to all users for free, starting March 28. Nvidia sees it and the Nvidia ACE technology as a stepping stone that could one day lead to truly dynamic NPCs.
“If you have MMORPGs with Nvidia ACE in it, NPCs will not be stagnant and just keep repeating the same dialogue — they can just be more dynamic and generate their own responses based on your reputation or something. Like, Hey, you’re a bad person, I don’t want to sell my goods to you,” Riawan said.

Trump says he has no regrets about starting the Iran war as U.S. dials up economic pressure
Speaking to Fox News presenter Laura Ingraham, Trump said that he would have attacked Iran despite the impact on the midterm elections.
U.S. President Donald Trump said he has no regrets about starting the Iran war and added that “If I had it to do again, I would do exactly what I did.”
Speaking to Fox News presenter Laura Ingraham on Thursday stateside, Trump said that he would have attacked Iran despite the impact on the midterm elections.
“If we hadn’t done Iran, you would be cruising to midterms victory right now,” Ingraham told Trump, to which Trump replied “supposing we were cruising, and all of a sudden Iran has a nuclear weapon. They would use it.”
He added that if Iran had a nuclear weapon, the Islamic Republic would “wipe out” Israel and the Middle East, and start hitting U.S. cities.
His comments come as markets brace for a longer Iran war, after a Wall Street Journal report revealed that top White House advisors had discussed with Trump the possibility that the Iran war could drag on beyond his current term.
Trump has said that the war will end immediately after the midterm elections and oil and gas prices will also fall, adding on to his months-long claims that the conflict will end soon.
In separate comments to NewsNation on Thursday, Trump denied reports that there was any damage to U.S. assets, after Iran claimed it had hit multiple U.S. fighter aircraft at a base in Jordan.
“No damage. No nothing,” Trump said, when asked if there was any truth to the reports.
Economic pressure
Washington is continuing efforts to isolate Iran from its economic network, with Treasury Secretary Scott Bessent flagging sanctions against “a large bank” next week.
“We’re going to do it on Monday because we want to honor the memory of our fallen citizens on 9/11. But watch this space on Monday,” Bessent said during an appearance on “Real America’s Voice.”
Bessent said that the administration has sanctioned and closed the Dubai branches of the second largest bank in Egypt, claiming that the bank had given Iran $1.8 billion dollars. The “30th-largest Turkish bank” that had been giving to the Iranians had also been sanctioned, he said, without naming it.
The U.S. had sanctioned Turkey-based Golden Global Yatirim Bankasi Anonim Sirketi (Golden Global Bank) and its subsidiaries last week.
Trump, in the NewsNation interview, was also asked how Iran could continue holding out under the current economic pressure.
“I don’t know that they’re gonna be able to hold out,” Trump said. “But it’ll get settled after the elections. Or maybe sooner. But it’ll get settled right after the election.”
Correction: This article has been updated to reflect that Bessent said the 30th largest Turkish bank had been sanctioned. An earlier version misstated the bank’s ranking.

U.S. diesel price tops $6 per gallon, a record high as Ukraine and Iran wars ripple through economy
U.S. diesel prices hit their highest level ever as fuel supply disruption stemming from the Ukraine and Iran wars lifts transportation costs.
U.S. diesel prices hit $6 per gallon on Friday for the first time ever, as fuel supply disruptions triggered by the Ukraine and Iran wars raises transportation costs across the entire economy.
Truckers and farmers are paying about 63% more to fill up their semis and tractors than they did at this time last year, according to data from AAA. The average price nationwide is now about $6.06 per gallon.
Prices are even higher in California, the biggest agriculture state in the U.S., at $7.98 per gallon.
Fuel costs are rising as crude oil prices have surged in response to a sharp escalation in fighting between the U.S. and Iran this month. U.S. crude oil futures topped $100 per barrel on Thursday for the first time since May. The contract has gained about 20% in September.
Diesel is the real lifeblood of the economy even though consumers tend to pay more attention to retail gasoline prices, said Bob McNally, president of Rapidan Energy, in an interview with CNBC’s “The Exchange” on Tuesday.
Higher diesel prices are passed down to consumers in what they pay for food, consumer goods and energy. Diesel fuels the trucks, trains and ships that bring goods to market. It powers the machinery that farmers use to plant and harvest food. And it heats homes and generates electricity in some cases.

“It’s the more insidious, more costly, and more impactful fuel,” McNally said. “As we climb higher, it is a real concern.”
Diesel prices at these levels will be a “silent killer” for the economy, said Patrick De Haan, head of petroleum analysis at GasBuddy, in an interview with CNBC’s “Power Lunch” Tuesday.
Gasoline prices, meanwhile, have never been this high this late in the year, De Haan said. Prices at the pump hit a Labor Day record of $4.15 per gallon earlier this week. Americans are spending about $700 million more per day on gas and diesel than they did a year ago, the analyst said.
“There’s sticker shock there for consumers,” De Haan said.
Fuel costs are rising as the Iran and Ukraine wars have disrupted global supplies. Kyiv has pounded Russian refineries, forcing Moscow to ban diesel exports. Iran and its militant Houthi allies in Yemen have also hit the refineries of U.S. Gulf allies. Fuel exports through the Strait of Hormuz are constrained due to the Iranian attacks on tankers.
The wars in Eastern Europe and the Middle East have shut down refineries with about 5 million barrels per day of capacity, said Valero Chief Operating Officer Gary Simmons on the U.S. refiner’s July 30 earnings call.
The world has lost nearly 8% of its diesel supply with little spare refining capacity available to make up the shortfall, said Andy Lipow, president of Lipow Oil Associates, in a Wednesday note.
Rising diesel prices pose an “enormous challenge” for the Trump administration, said Helima Croft, head of global commodity strategy at RBC Capital Markets, in a Sept. 4 interview with CNBC’s “Power Lunch.”
“U.S. refineries are running at 98% utilization rates — there is just no spare capacity,” Croft said.

Buffett’s confidence in troubled decade-old acquisition finally pays off
Warren Buffett has said he paid too much for Precision Castparts in 2016. Now its complex metal castings are in high demand.
(This is the Warren Buffett Watch newsletter, news and analysis on all things Warren Buffett and Berkshire Hathaway. You can sign up here to receive it every Friday evening in your inbox.)
Buffett’s confidence in troubled decade-old acquisition finally pays off
Six years ago, when Berkshire Hathaway took an $11 billion write-down of its $37.2 billion 2016 acquisition of Precision Castparts, Warren Buffett wrote in his annual letter to shareholders he had paid “too much” for the company, which makes “complex metal components and products.”
While it was a “fine company – the best in its business,” he had been “simply too optimistic” about its profit potential, a “miscalculation … laid bare” by the enormous downturn for the aerospace industry, Precision Castparts’ largest customers, amid the Covid pandemic.
In a CNBC interview when the deal was first announced, Buffett admitted it was “a very high multiple for us to pay,” but told shareholders at the 2016 meeting he had great confidence in Mark Donegan, the company’s CEO, both then and now, and the company’s long-term profit outlook.
It’s taken longer than he planned, but Buffett’s purchase is now looking pretty good.
As Reuters puts it, there is currently a shortage of the “complex” products Precision Castparts makes that are essential for engine turbine blades.
They’re also used in natural gas turbines, which are in demand to produce energy for artificial intelligence data centers.
This week, GE Aerospace announced it would pay $11.75 billion to acquire Consolidated Precision Products, one of the few companies that competes against Precision Castparts.
Barron’s calls that “pricey” at 26 times projected 2027 earnings before interest, taxes, depreciation, and amortization.
Using the same multiple, Barron’s estimates Precision Castparts is worth around $100 billion. That’s well above the potential value of $60 billion to $75 billion it cited in an article last month that said the unit “probably has become one of the more valuable divisions” of Berkshire.
It’s also nearly three times the 2016 purchase price.
In the Barron’s piece, Andrew Bary said Berkshire, and its share price, aren’t “getting much credit” for the subsidiary’s rising value, in part because CEO Greg Abel, like Buffett, doesn’t do analyst conference calls or investor events that could draw attention to the unit’s performance.
His recommendation: “Without Warren Buffett at the helm, Berkshire may have to start telling its story if it wants to attract a new generation of investors. This year’s trading action suggests that something may need to change.”
Berkshire bounces a bit as Wall Street sells off
Berkshire Hathaway shares managed a modest gain this week even as Wall Street’s major averages declined, a small departure from the 2026 “trading action” Bary cites.
Both the Class A and Class B shares gained almost 0.9% while the S&P 500 fell by 0.8%.
Until Friday’s bounce, that benchmark index, along with the Dow Industrials and the Nasdaq Composite, had dropped four days in a row as oil and bond yields moved higher.
Even with this week’s outperformance, Berkshire’s B shares still trail the S&P 500 by more than 10 percentage points so far this year.
Nebraska candidate moves to replace ad that included Buffett’s image
The campaign team for the Republican running in Nebraska’s 2nd Congressional District accelerated the deployment of a new campaign ad after Susie Buffett complained about a previous commercial that briefly included an image of her father, Warren Buffett.
In the ad, a picture of Buffett and his name appear on screen for roughly two seconds as candidate Brinker Harding says, “Here in Omaha, we know a thing or two about the stock market, some more than others. But we do it without insider information.”
He then goes on to highlight his call for a ban on Congressional stock trading, saying some lawmakers “trade on secrets you’ll never know,” as they “get rich” while “we barely get by.”
In a report that led its 10 PM CT newscast Wednesday evening, ABC affiliate KETV in Omaha reported Susie Buffett had asked Harding on Sept. 2 to remove the ad.
She told the station, “I think it’s worth it to say that Warren did not give Brinker his permission to use his face or name in his ad.
“It implies that my dad endorses him. He did not have permission to use it.”
The KETV report quoted Harding as saying in a statement, “In Nebraska, we work hard and support each other, and we do it honestly. Warren Buffett exemplifies that, and that was the point of my ad.”
The report said Harding did not comment on whether the ad would be taken down but noted “it does look like new ads from his campaign are beginning to run on some stations.”
A Harding campaign spokesperson told me the campaign did not think its ad implied a Buffett endorsement, but to be respectful to the Buffett family, it responded to her concern by accelerating the rollout of its next planned ad by several days, although its effort was hampered by the Labor Day weekend.
The commercial now running does not show or mention Buffett.

HIGHLIGHTS FROM CNBC’S BUFFETT ARCHIVE
The effects of 9/11 on Berkshire and the insurance industry (2002)
Warren Buffett shares his thoughts on the 9/11 attacks and explains how Berkshire’s insurance companies have started taking terrorism into account when writing policies.
AUDIENCE MEMBER: I know you lost a lot of money as a result of 9/11. But I would like to know how 9/11 changed your life and your investment strategy?
WARREN BUFFETT: It made everybody, I think, in the country aware, I mean, we’ve gone through world wars and all of that, and essentially felt quite protected within these borders.
And I have been quite worried about — Charlie can attest to — you know, the possibility, particularly of some kind of nuclear device in this country, by — probably more likely by terrorists than by some, at least, declared act of war by another state.
And 9/11 made everybody realize that as humans have not progressed, particularly, in terms of how they behave with each other over the years, they have progressed enormously in their ability to inflict damage on those they hate for one reason or another…
In terms of the business aspects of it, in your question, obviously the area at Berkshire that it effects most significantly, by miles, is insurance.
And prior to 9/11, even though we recognized that there could be huge monetary damages that flowed from the activities of what I would call deranged people, we hadn’t really written the contracts in such a way as to either get paid for taking that risk or to exclude the risk. In other words, we were throwing it in for nothing.
We had excluded risk for war. I mean, we knew that we’d seen what had happened in England in the 40s, and so we had taken account of something that some of us had seen with our own eyes, but we didn’t take account of something that we knew was possible, but we just hadn’t seen. And that’s, you know, that’s the human condition, to some degree.
Since September 11th, everybody in the insurance business recognizes that they had exposures that they weren’t charging for, and they either had to exclude those exposures or they had to charge for them.
We have written — first thing we had to do, of course, is we had lots of policies on the books that left us exposed to this, and most of those policies ran for a year, starting at different points. Those have run off to a great degree, but they’re not entirely run off.
The other thing we did was on new policies. We have sold a fair amount, quite a large amount, of terrorism insurance that excludes what we call NCB, nuclear, chemical, and biological, as well as fire following nuclear.
And, we can take a fair amount of exposure to that sort of terrorism, because it doesn’t — it won’t aggregate. It aggregated at the Twin Towers in a way that — World Trade Center — in a way that just about was as extreme as you could get for non-NCB-type activities.
I mean, that was a huge amount of damage done without nuclear, chemical, or biological.
But we can have tens of billions of dollars with NCB excluded throughout a greater New York area, or something, but we can’t have hundreds of billions of exposure that would be exposed, say, to, nuclear activities, because there an act or two, or three, coordinated, could cause damage that would destroy the insurance industry.
And if we had coverage on that, it would destroy us as well.
