Not really, AMD’s FSR upscaling can increase visual quality/fidelity while using less power than rendering at full resolution. This can be easily seen in Steam Deck’s battery life improvement when enabling it. Scaling this to millions of devices can indeed reduce energy usage.
When you read about “AI power consumption”, its mostly about training the models, not as much the usage after it’s trained.
Nowadays I just play something else, so many games out there that work flawlessly (thanks to wine/proton). I also did virtualization successfully for some time but it can take a while to get it right. The best and simplest solution is to get a separate SSD just for windows and dual boot.
