most games which require that big PC are poorly optimised and often times they arent even fun. these companies focus on visual fidelity and give all their engineers insane machines to build the games on. that has beenn destroying PC gaming way before AI/LLMs came into the picture.

I am using AI now to make a game engine that will run and make 'nice enough' graphics on simpler machines. things like laptops with iGPU and 4gb of ram.

U can still get quite ok graphics, and make very complex and rich gameplay systems using such a machine. It just needs to be the target machine while developing so the right tradeoffs are made.

Which is not a bad thing per se: most of use could use our devices a little longer than we usually do.
