The rise of AI NPCs has felt like a looming threat for years, as if developers couldn't wait to dump human writers and offload NPC conversations to generative AI models. At CES 2025, NVIDIA made it plainly clear the technology was right around the corner. PUBG developer Krafton, for instance, plans to use NVIDIA's ACE (Avatar Cloud Engine) to power AI companions, which will assist and banter with you during matches. Krafton isn't just stopping there it's also using ACE in its life simulation title InZOI to make characters smarter and generate objects.
While the use of generative AI in games seems almost inevitable, as the medium has always toyed with new methods for making enemies and NPCs seem smarter and more realistic, seeing several NVIDIA ACE demos back-to-back made me genuinely sick to my stomach. This wasn't just slightly smarter enemy AI ACE can craft entire conversations out of thin air, simulate voices and try to give NPCs a sense of personality. It's also doing that work locally on your PC, powered by NVIDIA's RTX GPUs. But while all of that that might sound cool on paper, I hated almost every second I saw the AI NPCs in action.
TiGames' ZooPunk is a prime example: It relies on NVIDIA ACE to generate dialog, a virtual voice and lip syncing for an NPC named Buck. But as you can see in the video above, Buck sounds like a stilted robot with a slight country accent. If he's supposed to have some sort of relationship with the main character, you couldn't tell from the performance.
I think my visceral aversion to NVIDIA's ACE-powered AI comes down to this: There's simply nothing compelling about it. No joy, no warmth, no humanity. Every ACE AI character feels like a developer cutting corners in the worst way possible, as if you're seeing their contempt for the audience manifested a boring NPC. I'd much rather scroll through some on-screen text, at least I wouldn't have to have conversations with uncanny robot voices.
During NVIDIA's Editor's Day at CES, a gathering for media to learn more about the new RTX 5000-series GPUs and their related technology, I was also underwhelmed by a demo of PUBG's AI Ally. Its responses were akin to what you'd hear from a pre-recorded phone tree. The Ally also failed to find a gun when the player asked, which could have been a deadly mistake in a crowded map. At one point, the PUBG companion also spent around 15 seconds attacking enemies while the demo player was shouting for it to get into a car. What good is an AI helper if it plays like a noob?
Poke around NVIDIA's YouTube channel and you'll find other disappointing ACE examples, like the basic speaking animations in the MMO World of Jade Dynasty (above) and Alien: Rogue Incursion. I'm sure many devs would love to skip the chore of developing decent lip syncing technology, or adopting someone else's, but for these games leaning on AI just looks awful.
To be clear, I don't think NVIDIA's AI efforts are all pointless. I've loved seeing DLSS get steadily better over the years, and I'm intrigued to see how DLSS 4's multi-frame generation could improve 4K and ray-tracing performance for demanding games. The company's neural shader technology also seems compelling, in particular its ability to apply a realistic sheen to material like silk, or evoke the slight transparency you'd see from skin. These aren't enormous visual leaps, to be clear, but they could help deliver a better sense of immersion.
Now I'm sure some AI boosters will say that the technology will get better from here, and at some undefinable point in the future, it could approach the quality of human ingenuity. Maybe. But I'm personally tired of being sold on AI fantasies, when we know the key to great writing and performances is to give human talent the time and resources to refine their craft. And on a certain level, I think I'll always feel like the director Hayao Miyazaki, who described an early example of an AI CG creature as, "an affront to life itself."
AI, like any new technology, is a tool that could be deployed in many ways. For things like graphics and gameplay (like the intelligent enemies in F.E.A.R. and The Last of Us), it makes sense. But when it comes to communicating with NPCs, writing their dialog and crafting their performances, I've grown to appreciate human effort more than anything else. Replacing that with lifeless AI doesn't seem like a step forward in any way.This article originally appeared on Engadget at https://www.engadget.com/gaming/pc/nvidias-ai-npcs-are-a-nightmare-140313701.html?src=rss
