No Performance Boost in FCPx fron 6900xt to 5700xt

[techgoggles]

I updated to Big Sur 11.4, to use my 6900xt but Did not see any performance improvement in FCPx compared to 5700xt, and my vega x64 was actually faster than 5700xt.
any recommendations?

upgraded from Catalina to big sur from the appstore after updating open core to 0.7

Try doing the following if you haven’t already.

go into the Config.plist and navigate to Kernel -> Patch, Scroll down to the very last patch in the list (39) and enable it followed by disabling the patch directly above it (38). Save, Restart and your find your GPU geekbench score and frame rates in games will be better.
