So we are saying my intel 13900kf Is bottlenecking my GPU at 4k. This is not reaching 100% anymore in any of the cores. the max is reaches is 85% usage in a couple of cores?The real question here is why are you reaching 100% with your CPU. It doesn't surprise me at all that things are falling apart when you do.
Just throwing this in the mix, is it simply that this is a natural bottleneck of your CPU and you are just trying to drive the frame rates too high? The GPU is fine but your CPU is not? The 4090 is known for the fact that it out performs even the best current CPU's.
It's not your cable, by the way, if you exceed the limits of that you just get black screens.
to be honest I thought bottlenecks were limited at 4k...
cheers
