I just upgraded from 11.04 to 11.10 and i noticed that graphics are slower. I had the nvidia driver downloaded from their website in 11.04. After the upgrade the pc wouldn't actually boot in kernel 3.0, so i went to 2.x.38 and installed the nvidia driver from the repos. After this change, 3.0 was working but, as i said, with some regressions.OpenArena, for example, was slower. Plus, I noticed in Openarena tearing and in FF too. It may be a system wide thing though, i don't know.
So my question is ... how can i verify if the driver is installed correct?
But if i understood the problem incorrect, please help me out identifying it!
