Hope you’re doing well and so sorry you’re having this issue. If you’d like to look at the Unreal Engine 5 changes you can do so here: UE5 changes.
But the important bit is:
Ray Tracing support with Lumen Hardware Ray Tracing: Standalone Ray Tracing features are being deprecated in Unreal Engine 5 Early Access. However, the engine’s ability to compute these lighting effects is not being removed, since Lumen covers these lighting features. What is being removed is the standalone Ray Tracing system that has been developed in Unreal Engine 4.
this is comment from Daniel Wright, unreal developer
**"Nvidia gtx 1000 series have only emulated ray tracing, which is so slow that it gives a **
**very poor experience out of the box. You can use ray tracing anyway with ** r.D3D12.DXR.AllowEmulatedRayTracing=1 in ConsoleVariables.ini"
but unfoundedly this console command stopped working in source code
I hope epic adds this console command for gtx 1000 again
