This issue still occurs after multiple driver updates

In my experience this tends to happen more with RT reflections but not with RTGI. Try playing with just RTGI and see if you still get it.

Btw unless this update fixed it, you can’t exit the game with just one of them on without the game failing to save/load RT settings next boot up :upside_down_face:

Also if that works it’s worth trying high rt reflections just to see if low mixing rt reflections with screen space is the cause
