No Pathtracing support in 5.0 or 5.1

Dual Titan Voltas. Pathtracing support worked fine in 4.27.
Now gone in 5.0.

Can someone from Epic please respond?
Have hardware requirements changed?

Same issue

Try this video from William Faucher:

Yes. Watched.
Warning message I get
LogD3D12RHI: Warning: Ray tracing is disabled for NVIDIA cards with the Pascal architecture.

However am running Titan Volta, which AFAIK is NOT Pascal.
