Unreal Engine 4 DX 12 problem

Hello I have a problem with the engine when I turned on DX 12 and ray tracing in the settings. The engine behaves strangely, flashes black all the time and I can’t work normally. When I want to choose something from the menu I can’t because the image from the engine is superimposed on the context menu :frowning:

I have a GTX 1070 8GB I7 7700HQ and I’m surprised this is happening because this gtx received DXR support.

Somebody’s gonna help

Although raytracing is enabled for that series of graphics cards, they aren’t capable of using it very well since they aren’t designed for it
