phoronix-test-suite.supertuxkart.1024x768.Fullscreen.Ultimate.1.GranParadisoIsland.frames_per_second
-30.4% regression
I run “phoronix-test-suite run supertuxkart-1.5.2” on my CML Ubuntu 18.04.5 LTS device, and compared the fps between patch and original upstream, there is no any fps performance drop issue.
5.10.0-rc3 upstream / 5.10.0-rc3+patch
fps 12.586326 / 12.687711
Best Regards,
