Artifacts in gunner sight

Hey guys, already posted this on reddit and almost freak out because of the artifacts.

See here https://youtu.be/sOG5IhCfnKs

Whenever I go into gunner sight on certain maps, especially the test drive, I get strange artifacts when swiveling the view. I’m running a brand new 5090 and newest driver, running DX12 without RT. DLSS set to native. Slightly undervolted. Issue persists even if I disable the undervolt.

I already tried turning RTX on and off, switching renderer to DX11 and back und testing motion blur and reflection details. Lowering reflection details to minimum made it slightly better but didnt solve the problem. Also tried repairing game files through launcher without success.

Is this a known game issue or is my GPU cooked?
