Question GTA V: Low FPS on RTX 2070 Super

[iker3085]

I have been searching a lot and appearantly I'm not the only one with this issue.

This is my system:
Ryzen 5 3600x
MSI X570 Gaming Plus
KFA2 Geforce RTX 2070 Super 8GB
2x G.Skill Ripjaws 16GB DDR4 3200
Samsung Evo Plus 970 500GB
Be Quiet Straight Power 11 650W
Dell Ultra Shap U2515H

I have set the graphics to the highes possible, tried 1080p and 1440p, enabled and disabled Vsync. When I do the graphics benchmark, I only get to 30-40 fps at 1080p with Vsync enabled and to around 50-60fps with Vsync disabled. I saw benchmarks with worse systems and there were 90-120fps with the same settings.

I already went to safe mode, used DDU to uninstall my graphics driver and manually installed the latest Nvidia drivers (442.50). Nothing has changed.
Hopefully you guys can help me.

Edit:
GPU usage is around 98% during the benchmark at 58°C, RAM usage at around 8800MB

latest bios and chipset driver?
userbenchmark said high background cpu usage

I installed the latest chipset drivers from MSI, didn't update the bios though.

Maybe I had something running in the background, I just tried to run the benchmark again, unfortunately I can't get it to complete anymore. It always counts down at "waiting for sustained writes", then it finishes and shows 0% for Gaming, Desktop and Workstation
