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
We have tested it before, the fps is 35.32
and 24.59 for the following
two commits, but your test result is about 12 fps, is it reasonable? I
guess something in your setup drop both performances for the two tests
you have run.
