Performance Issues. Dx12 and Vulkan Cap FPS at 85-90

Hello I have been having issues with performance since the 3.22 update.

My FPS dips down to 30, and then caps when trying to go back up. I have to switch my resolution/windowed mode until it uncaps it again. There is tearing whether V-Sync is on or off. I have fiddled with GSync/FreeSync, display settings on the graphics card, as well as in windows. Nothing is working.

The only renderer I have been able to play on is Dx11(unstable) since Dx12 and Vulkan both cap my fps out at 85-90fps and are equally as unstable.

EVGA GeForce RTX 3080 FTW3 ULTRA GAMING 16gb
Ryzen 5600x

I have tried multiple monitors with various refresh rates.

Same problem for me, capped at 42 fps with Vulkan and DX12, while DX11 is unstable.

I switched from PCIe 2 to PCIe 4 and the fps cap changed from 42 to 94...

Vulkan and Dx12 cap me at 45 no mater the sync setting and graphics level. Switching to dx11 uncaps.

Same problem here.

Had cap fps on vulkan and dx12! After an intense search got the answer. My gpu was wrong seated (loose)! it can be also if you have a PCI card (audio, wi fi, etc) that makes your GPU work in less than 16x pci lanes! You can look with GPUz software! (give a stress test to your gpu when you open GPUz and look for how many pci lanes is using!!) If your gpu is using 8x, 4x or 2x pci lanes, that is why PoE caps your fps.
