AI is coming for your PC games, but you should be excited, not worried

The tech community has been oversaturated with AI this past week, from ChatGPT to Google Bard, but not without reason. We see fads like NFTs and web3 come and go, but AI is here to stay — even in your PC games.

It’s not all doom and gloom, though. AI and machine learning has already proven itself wildly useful in PC gaming, and it has far-reaching implications for how games are made and experienced. I’m not trying to fit a square peg into a round hole here — and if you stick with me, you’ll see why.

How it’s being used now

The touchstone for AI in PC games right now is Nvidia’s Deep Learning Super Sampling (DLSS). Train an AI model how to reconstruct a frame in a game and render the game at a lower resolution, and enjoy free performance without an impact on your visuals.

DLSS has gotten really good, and although there are algorithmic competitors like AMD’s FidelityFX Super Resolution (FSR), Nvidia has proven that AI provides an edge. DLSS 3 is a testament to that, providing extra frames generated solely by the AI. AMD probably wouldn’t disagree, either — its latest RX 7900 XTX and RX 7900 XT include a yet-unused AI accelerator.

Beyond upscaling, AI has shown up in Nvidia’s RTX Remix modding platform, which offers a suite of AI tools to enhance textures, add additional lighting to scenes, and more. Portal RTX is a great example of what these AI tools can do to revitalize an aging game.

Nvidia isn’t the only one here, either. A recent mod for the classic Morrowind added voice lines to the game that were generated with AI. With the massive dump of dialogue in Morrowind, that’s something that wouldn’t be possible without either years of work from modders to hire voice actors (unlikely) or a truckload of cash from Bethesda (even more unlikely).

Those are just a few high-level examples of how AI is being used to enhance games today, but it’s important to remember the bedrock of AI within games themselves. Tools like Unreal Engine 5’s MassEntity promise to provide huge batches of AI-driven characters with simple inputs. And that’s one of the most exciting aspects of AI in PC games — its use to speed up game development.

Efficient game development

NVIDIA GameGAN: Celebrating 40 Years of PAC-MAN with Game-Changing AI

In 2020, Nvidia trained an AI model to recreate Pac-Man. It was trained on 50,000 episodes of the game, and two neural networks were able to recreate a playable version of Pac-Man without an underlying game engine. No set rules, no parameters — the AI simply looked at the game being played a lot and figured out how to recreate it.

It’s a testament to how far AI has come in terms of accelerating game development. Don’t worry that AI is going to start making PC games for you, though. As Take-Two CEO Strauss Zelnick said in a recent earnings call, “[AI is] not going to allow someone to say, ‘Please develop the competitor to Grand Theft Auto that’s better than Grand Theft Auto‘… people will try, but that won’t happen.”

That may not happen, but Zelnick was clear that AI has a big use in game development. One usage that’s been rising over the past several years is AI-driven Quality Assurance (QA) testing. Players generally spend thousands of hours uncovering only a fraction of bugs in PC games, but AI can run thousands of tests on a game within seconds.

AI can also be used to create more complex, varied games, particularly those with branching paths. For example, AI Dungeon 2which released in 2019, is a text-based adventure generated by AI that can provide infinite stories. Then there’s the endless string of stories around procedural generation in games like No Man’s Sky that are driven by algorithms creating billions of planets.

Although games like No Man’s Sky are generating new worlds, they still come from a core of human design. Generative AI allows completely new experiences that don’t need set parameters, just enough training.

I recently played the Shadows of Doubt demo — a neo-noir thriller that procedurally generates the full world — via the Steam Next Fest. It allows you to have a completely unique experience each time you play, with different clues, NPCs, and environments. Applying AI to this type of setting should be enough to get anyone excited, as it provides unique experiences for each player that touches the game.

Not without concern

For as exciting as AI is in PC games, it also brings up a lot of valid concerns. After all, we’ve seen a Starcraft 2 AI that beat nearly every player in the world, and it’s not hard to imagine the nefarious uses of AI in competitive games.

There’s also the large swath of jobs in game development that could be impacted by AI. From concept art to level design to voice acting — AI already can handle these tasks, and it’s much cheaper than hiring a league of employees. My hope is that AI is used to expand the scope of game development on this front rather than reducing it. Similar to No Man’s Sky, I hope it’s leveraged to help smaller teams build larger games and not to simply raise the bottom line of the world’s largest publishers.

Although there are valid concerns, there’s also a lot to be excited about. As DLSS, RTX Remix, and something as out of left field as a Morrowind voice acting mod demonstrate, there are uses of AI in PC games that haven’t been imagined yet, and that’s an exciting place to be.

Whatever you do, don’t buy an Nvidia GPU right now
Three RTX 4080 cards sitting on a pink background.

If you're trying to build or upgrade a PC, now is the best time to buy many different components. Black Friday brings huge discounts on parts, making it the best time of the year to stretch your dollar the furthest. But this year, there's one important part you should wait on: a new Nvidia graphics card.

That's not because Nvidia's latest GPUs are bad -- they're some of the best graphics cards you can buy -- but because we're likely on the brink of a major refresh to Nvidia's current lineup of GPUs, and the deals we're seeing now will probably become the norm in just a few months.
A Super refresh incoming?

Don’t believe the hype — the era of native resolution gaming isn’t over
Alan Wake looking at a projection of himself.

Native resolution is dead, or so the story goes. A string of PC games released this year, with the most recent being Alan Wake 2, have come under fire for basically requiring some form of upscaling to achieve decent performance. Understandably, there's been some backlash from PC gamers, who feel as if the idea of running a game at native resolution is quickly becoming a bygone era.

There's some truth to that, but the idea that games will rely on half-baked upscalers to achieve reasonable performance instead of "optimization" is misguided at best -- and downright inaccurate at worst. Tools like Nvidia's Deep Learning Super Sampling (DLSS) and AMD's FidelityFX Super Resolution (FSR) will continue to be a cornerstone of PC gaming, but here's why they can't replace native resolution entirely.
The outcry
Let's start with why PC gamers have the impression that native resolution is dead. The most recent outcry came over Alan Wake 2 when the system requirements revealed that the game was built around having either DLSS or FSR turned on. That's not a new scenario, either. The developers of Remnant 2 confirmed the game was designed around upscaling, and you'd be hard-pressed to find a AAA release in the last few years that didn't pack in upscaling tech.
