pc has already had this with Xbox game bar and the perf impact isnt really noticable. if I recall correctly modern gpus have some dedicated chips for video rendering that are otherwise idle. I would assume there is some hit to vram that could hurt if you’re limited on it, but for most people it should be fine.
…any tips on getting in? I tried checking the store page to see if any friends have it and none of mine do 🙁
