Question Rtx 3080 not running above 50% usage in almost every game


May 18, 2021
In almost every game I run my GPU doesn't go over 50% max usage and most of the time its under 40%. I have set most of my 3d settings to max performance in GeForce control and set power management to max performance as well. I'm wondering if its a bottleneck issue.

Asus tuf 3080 gpu
Intel core i9 9900k cpu
16gb corsair vengeance ram at 3200mhz
Asus z390-A motherboard
Corsair rm750 psu
The reason why you're seeing low utilization is because the RTX 3080 can easily pump out a lot of frames at 1080p. This means your CPU is now more responsible for shoving work for the GPU to do. If it can't do it fast enough, then the GPU is going to idle, which you see as lower utilization.

So in this case, the CPU is the bottleneck here. However, this isn't necessarily a bad thing if you're still getting the performance you want.

If you want to make yourself feel better about higher GPU utilization, you can make sure all the settings are cranked up, including any anti-aliasing, or you can enable DSR and select a higher resolution like 1440p or 4K, and DSR will downscale it to 1080p.
