Never had a problem with Maverick, always very fast. I upgrade to Natty and the graphics seem to be very lagged. CPU, load, and memory usage is low, all graphics are choppy and lagged though. I have the proprietary driver installed and everything. Alt-Tabbing takes 3-5 seconds for the dialog to popup, zooming in with compiz zoom makes things very slow. I never had any of these problems with 10.10 | |||||

In ubuntu 11.04 the setting is located on ccsm>OpenGL>Sync to VBlank. When fglrx is enabled, this should be unchecked otherwise performance is sluggish and slow. | |||

Hey, if you install compizconfig you can try unchecking the V-Blank in general options, as in the open-source ATI driver in natty there is already V-sync activated. It did the trick for me so you can try it | |||

Had the same problem, but using this info solved it: http://www.linuxinsight.com/your-ati-radeon-very-slow-on-xorg-x-server-1.3.html Now my Ubuntu is snappy beyond my imagination | |||
