I’ve just made an interesting observation. If I change the CPU frequency
scaling governor in /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
from ondemand to performance, desktop effects seem to be smoother in some
situations. I thought that performance of desktop effects is mainly a GPU
problem so I wonder why fiddling with CPU frequency helps.
Is it possible that changing the governor results in performance improvements
for desktop effects or am I just hallucinating? ;-) If yes, is there a
solution where I don’t have to let my CPU run with maximum frequency all the
time, e.g., changing some parameters so that it runs with maximum speed when
I actually use effects, but not always?
Best wishes,
Wolfgang
