Sure. Maybe. Maybe not.
The cpu pre-renders the frames, sets fps limit. Ships frames to gpu, puts them up on screen according to detail levels and resolution.
So if the cpu is good for 150fps, ships that to gpu which has ultra-max details @ 4k, even the 2080ti might struggle to get all 150fps on screen. Might get 60ish fps. Dropping to low details might get you the full 150fps,might not. Gpu bound.
So if the cpu is good for 150fps, ships that to gpu which has uber-low details @ 1080p, the 2080ti will be half asleep it'll be so bored. Even raising detail levels to ultra-max won't change anything, you'd still get full 150fps on screen because that's all cpu can do. Cpu bound.
Big difference, one small change.
