--- Comment #6 from John (john.ettedgui@gmail.com) ---
The schedutil patch didn't seem to change anything, though the 4th hunk of
cpufreq_schedutil.c didn't apply and I had to do it manually, so it is possible
I messed up somewhere (I copied/pasted it so it's unlikely, but I thought it'd
be better to say it).
As for pstate, I think that's the first time I've seen my CPU scaling on
pstate's powersave. I've tried the game, and I think, but not sure, that when
it started the sound cracked for just a bit, maybe before the CPU scaled up
enough? After that no issue, and I verified the CPU was at its maximum
frequency. When I quit the game, the CPU scaled down to its minimum frequency
within 2 seconds. Pstate's performance still doesn't scale, is it expected? I
thought on pstate both would.
Thank you!
