|
|
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. _________________ Ex-Gentoo Developer

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.)? |
