It’s not just simulation heavy games that stress the CPU a lot. There are lot of single player games that would (or could) benefit from this. Things like enemy and character ai (not that LLM Ai of sort, I mean just the normal game logic) are stressing the CPU a lot and can cause stutter in certain regions of the games. It does not mean a constant stress, but like in Witcher 3, Baldur’s Gate 3 or Crimson Desert in certain situations when its not about the graphics anymore (dungeon with lots of enemies, town with lots of people).

But we need more testing with those games before coming to a conclusion off course. We can just speculate at this point.

There’s nothing wrong with using AI

Well, that is debatable. For some its using Ai is a problem by definition, its not even about the result. A few issues: a) Ai is unethically trained on data without respecting the original license, b) using Ai (probably even paying for it) supports Ai companies, which in turn are causing the massive issues in the tech price increases.
