openSUSE 11.2 64 / KDE

just thought I'd share.

One of my pet peeves is sluggish UI rendering. So recently I was messing
around, overclocking a bit, and I disabled cpu freq scaling / coolnquiet.

My desktop and windows draw WAY smoother and faster now.
The few 3d games that I play are smoother as well. Who knew freq scaling
could be so unresponsive? well not me, i never guessed.

Now I AM consuming more power of course, being at max clock rate 100% of the
time. But I haven't noticed much more heat or fan noise. I'm keeping it this
way. :)

For laptop users it's a good thing if the CPU only speeds up for
important stuff, not eye candy.

Does your machine have a GPU or integrated graphics? Desktop or laptop?

I'd expect a 'smart' powersaving scheme on a laptop to transfer as much
as possible of the load of drawing the eye candy onto the GPU (which,
even on full power uses a lot less than the CPU) and keep the CPU
clocked down unless there are lots of user tasks looking for cycles.

Its a Desktop with ATI GPU.

True, laptop users will not want to disable freq scaling or their battery
will die faster.

Where is that, in the BIOS?

I haven't spoken to my wife in 18 months.
I don't like to interrupt her.

Yes. For an AMD chip/mboard its called CoolnQuiet. Intel calls it
SpeedStep(?) or EIST I think. Disable it. You can keep C1E enabled.

I'm sure you could also disable it in Linux. Blacklist the powernowk8 module
or something.
