I tried on my desktop with gtx1080 but the editor keeps crashing at restart after enabling ray tracing and rhi12.
Many errors, also referring to oculusHMD. Submitted crashlogs.
edit: tried on another (older) laptop with quadro M1200. Editor launches fine but immediate crash after pressing ‘build lighting’ in the new (and nice looking) GPU lightmass settings tab. Error:
Assertion failed: (Index >= 0) & (Index < ArrayNum) [File d:\Build++UE4\Sync\Engine\Source\Runtime\Core\Public\Containers/Array.h] [Line: 674] Array index out of bounds: 74 from an array of size 0
