Sudden unexplained frame drop

Hi everyone

I rlly hope somebody have an answer for me.

I was relighting a prebuilt map and now I’m stuck in sub 20 frames no matter what I do, even deleting EVEYTHING, I’m still in 15 frames lol

Everything was fine, I switched to Epic Mode to capture a screenshot. After that, I’m constantly in sub 20s. Even when I switch to Medium settings and delete all the lights.

I also get the “D3D Devide Removed” message on screen and crash after.

My specs:

3070 Ti
AMD Ryzen 9 5900x 12-core
64G RAM

Please help this stuttered soul, My eyes can’t take it no more lol
