7900xtx Low Performance in SteamVR and VR in general

Purchased a 7900xtx at Microcenter on launch.  Just installed it tonight.  Replaced a 6800xt.  I'm running a 5600x CPU.

 

When my PC boots the bios screen is green.

When I try to play steamvr (The only reason why I upgraded) the performance is terrible.

Using FPSvr I can see that I am all in the green as far as frame time.  Under 6ms.  But I'm hitting reprojection hard and cant maintain above a 70fps on my reverb g2, which runs at 90fps.

If I put the 6800 back in everything is fine.

 

Did I get a lemon?

Thank you to everyone for your patience whilst we worked on investigating and improving the lower than expected performance in VR for RX 7900 series graphics products. 

The 23.7.1 release notes have a fixed issue listed for VR:
