Cyberpunk 2.3 - FSR4/Framegen

Hi guys,
I‘m new here and hope this question is inside the rules:

I managed to get FSR4 via Optiscaler on Cyberpunk, which looks absolutely stunning!
Now that patch 2.3 is out, I can‘t get the options in the menu to appear. I tried using Proton GE 10-4 with FSR4_UPGRADE=1 %command% - but it only shows FSR2 and 3.
Anyone already pulled this one off using bazzite?

See below: Update to MESA 25.2 and using Proton GE 10-10 with the Launch Parameter PROTON_FSR4_UPGRADE=1 %command%
does the trick!
Thanks to MRChandy!
