I got the same. FPS in Adrenalin Metrik Overlay isn't shown, and the stats from the game itself are grey ("fps/ms") and don't show the fps.
Radeon RX 6800 XT, Ryzen 7 5700X
First game with this issue so far. And every 30 minuites the game crashes with DirectX fuctioon GetDeviceRemovedReason failed with DXGI_ERROR_DEVICE_HUNG (The GPU will not respond to more commands) blablabla ...
Edit: The crash is solved by lowering clocks on Adrenalin on the gpu to 92%, that would be minus 200 MHz.
The cause of that DirectX error seems to be because of XMP profile for RAM being enabled..
Disabling that fixed it for me, in case it reappears for you.
