I think my CPU utilization in Doom Eternal is something like 30%. Duno never cared… all i know is that my GPU is at 100% thats all thats important in Video Games
In Video Games, If my CPU Utilization is higher than my GPU than im doing something wrong or the Game is not good optimized. Best case for me would be all CPU cores evenly used also the logical ones and lower than my GPU, since i want my GPU always at 100%. Easy to get in 4K Gaming.
