Question RTX 3080 not being properly utilized.

All of a sudden my RTX 3080 is not being utilized properly. It is detected in device manager, but I have to disable then re-enable it in device manager whenever I turn on my computer for it to work properly. Here are two images showing the performance in task manager:

I have my onboard graphics disabled via BIOS, and even when turned on it sees little utilization.

While idling at a main menu, I get ~30 fps, and after disabling and re-enabling the card I get my capped FPS of 144.

I have re-seated the GPU, and wiped and reinstalled drivers to no avail. I have also tested my old 980 and that works fine.

Here is a dxdiag as well:

What is your processor? My first guess is always bottleneck. Also, check Nvidia Control Panel, just in case you capped the FPS somewhere along the road. Also, try MSI Afterburner

CPU is i7-10700k, certainly not a bottleneck. I use Afterburner at a 144 cap. I've had this setup for a year and a half now. This issue only appeared today. Before that, performance was completely fine.

Hmmm. The PC may not see a need to run faster than 30 FPS when idling. Does it actually affect your PC in any way?

 

[delta4873]

Yes the performance is impacted in any game I play, I just listed the main menu idling as an example.

Turn off v-sync in global settings would be my guess. Only use v-sync per game settings. Windows is natively 29.97Hz, not quite 30Hz, so with a 144fps cap, if set globally in nvidia panel etc, that's more than double the Windows refresh, so v-sync will kick in and cut you to 30fps. Resetting the gpu in device management reapplies the cap, overriding the global setting.

Having v-sync set per game, v-sync only applies during gaming, allowing the gpu to freely run Windows at 30Hz with no v-sync.

No dice, and the FPS isn't stuck at 30, right now in game it's at 40. Bringing up a game like tabletop sim, and it hits the cap as well. Before doing the reset trick. The issue also appears when I put the PC to sleep, not just when it's turned off.

I was able to fix it, for some reason MSI Afterburner was severely limiting the power draw to the GPU. It was only getting about 100 W, instead of 300. Resetting the settings in MSI Afterburner fixed it.

Nice. 👍

Well done.
