In theory…yes? But I have a Ryzen 5600x and I don’t remember my cpu utilization in CP77 ever going above 60%, meanwhile GPU is consistently taxed at 90%, even without RT.
I mean it’s not really a big deal, the fake lighting in games got so good over the years that I sometimes prefer it over the RT implementation, believe it or not. Doom Eternal is particularly disappointing in that regard, apart from reflections I can’t even tell RT is on.
But the DLSS is kicking ass hard, as far as I’m concerned the #1 reason to get an RTX enabled card at this stage.
