You are maxing out your VRAM. Set ‘Texture Resolution’ to ‘High’ and see if that fixes it.

Also “limited by main thread” meaning your performance suffers because your CPU is not processing fast enough.

And turn off DX12, go back 11. DX12 is unreliable

@PacyFire Is correct. You are over the VRAM limit.

(Forget about the maimthread message. )

Texture resolution and super sampling is set too high!

Lowering those made a big difference for me. 5800X3D RTX 4070 12gb 3440x1440.

Texture resolution to high
Super sampling to 4X
Consider lowering TLOD to 150.
