Hi,
I installed 12.10 recently and noticed that the grafx drivers are slow and jerky in 3D. I mean with 11.10 and NVIDIA 280 proprietary drivers everything is super smooth, like switching desktops with the animated cube is flawless. XORG is used between 3 to 8% while processing the desktop effect. I have a GeForce 8600GT.
But under 12.10, with ANY of the NVIDIA drivers I used (173, 295, 304, 310-experimental and 313), whether installed from PPA or compiled by myself like I used to do in the past years, XORG is used up from 9 to 20% every time the cube animates to switch desktop, which makes it slow and mostly jerky during the animation. Not just the cube, but when my windows are swapping one in front of the others when I click on a background window to bring it to front (default KDE effect), that effect too is jerky and uses too much of CPU from XORG.
Even the Nouveau drivers in 12.10 are using up too much of XORG. A little less than NVIDIA drivers, I have found, but still too much to keep the 3D effects smooth, so it's jerky. It feels so uncomfortable.
Nothing else seems affected in terms of grafx.
Anyone experiencing similar issues?
I am about to try the PPA "ppa: xorg-edgers/ppa" and see if these bleeding edge updates can help.
Otherwise I am staying with 11.10. But what if 13.04 has the same problem? I can't stop upgrading until I find a release that works, there must be something I can do to improve performance, or at least log the bug to someone if it's one.
tnx!
