I've done some tests with nexuiz (a full 3d game, quite intensive for my video card)
without the option disable low impact fallback it is not playable, after enabling it I got nearly 60fps, sometimes with 1 second hangs, but the situation is not so bad... I think the key for 3d games is this option! I think that I should see the fps when using fglrx, but now it can't be used due to a X version mismatch After launching google earth with the option enabled, the system hangs, as I reported before (a hard reboot is needed) compiz does not take any advantage from this option :( it is sad because compiz performance is quite bad! scrolling is very slow (though improved) the animations are quite huggy, and everything is highly dependent on the cpu usage of the moment also take a look ad this Xorg.0.log line (II) RADEON(0): Render acceleration unsupported on Radeon 9500/9700 and newer. (II) RADEON(0): Render acceleration disabled Tormod, what do you think? -- ATI radeon: poor 3D performance https://bugs.launchpad.net/bugs/56692 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
