I was having trouble with jerkyness in my games for a long time (I have a 6800, so this shouldn't happen). I just recently realized that it was all caused by the cfq scheduler. I am on the standard 2.6 anticipatory scheduler now. Has anyone else had any experiences with schedulers and gaming? Any ideas as to which is the best one?

I've been running CFQ for an ages now, and I haven't noticed any "jerkyness" on games.

CFQ isn't designed for things like games. For gaming, you pretty much want the anticipatory or the deadline scheduler.

Eh...I think I was using a buggy version of cfq. (whichever one came in 2.6.9-nitro1).

Yes, there is, take a look at https://forums.gentoo.org/viewtopic.php?t=271176.

BTW: Does anyone has a good overview about the different schedulers (how they work, which schedulers fits best for which purpose etc.)?
