Karmic: Slightly Choppy/Stuttering Rendering
On my fresh Karmic Install I have an issue with 2D/3D rendering:
It is most apparent when playing Quakelive: While I have a very constant 125fps, it still looks as if I was playing with 10-20fps.
There is this constant stuttering. It's not a CPU load surge or anything like that, the stuttering is very uniform and always feels the same.
It's also apparent when moving around Windows on the Desktop or sometimes when watching video (even with mplayer and vdpau support) where a linear motion is stuttering with what looks like just about the same frequency as in the Quakelive example above.
So I'm using an 8-Series Nvidia graphics card. I've tried different drivers, changing sync to blank settings, but there's no change in stuttering at all.
In Jaunty everything works just fine though (with the same nvidia drivers)
I can't find any strange processes that would cause CPU load.
Generally, everything's running quite smoothly, though there's that underlying slight stuttering to everything rendered on the screen. It isn't disturbing or very noticeable when working or watching video, it makes it impossible to play Quakelive though.
I have no clue what could be wrong here...
