CPU or GPU ?

[p.b.]

Is the rain and the weather effects more cou bound or GPU bound in a game like assetto Corsa competizione.

The thing is: I had a friend testing assetto Corsa competizione in 4k with the weather setting on thunderstorm and max cars ( twenty something cars) with a 2080, a 6700k stock and 16 of ram and the system ran at 48, 50 and sometimes 60 fps. It was not able to run locked 60.

Would a high core count CPU (8 /+) handle the performance better, like a i9 9900k?

Thanks in advance.

use a monitoring software to determine to usage of the cpu and gpu.. at 4k res i would say the gpu is the limiting hardware. even a quad core cpu can push more than 60fps at 4k however quad cores will hold back some performance in terms of whatever the game uses the cpu for.

4K resolution performance is primarily handled by the GPU.
It`s pretty normal for 2080 not always get stable 60 fps in 4K with cranked up settings, if you are serious about maxed out 4K then it`s better to invest into 2080 Ti, this usually manages 60 fps.
If you are willing to play with the settings and not always max out everything then 2080 can manage 4K decently enough.

A quite simple test you can do here is just try a lower resolution. If the fps gets better it's GPU bound, if it doesn't, it's a CPU bottleneck. I suspect GPU as the CPU doesn't care about the resolution.

Certainly GPU setting. I never heard most demand graphics being use in the CPU as primary.

What is FTFY?

It's "fixed that for you", as what they said was close to how it is, yet not exactly correct, so I felt the need to fix it so others will have a better idea on how things work.

Cars (and maybe some graphic effects) are cpu, graphics are mostly gpu. Fps might be impacted by the cpu in racing games by the AI which drives the other cars, but I think this would be unlikely.

Try setting the mobo to max performance.

To determine what is happening install MSI Afterburner and configure it to look at cpu threads and all gpu figures. Is there 100% load on any of the cpu threads? Or gpu?

Rather than more cores, faster cores are desirable. With fast memory e.g. ddr4-3600.

This article tends to indicate it's the gpu and the programming. There are more articles on the web.
