    Measured with an application I am developing. No abnormal optimizations I can detect. Running with the highest possible settings (purely GPU-bound), using quad-buffer stereo and disabling vsync brings the fps down to ~61 on Vista and ~72 on ArchLinux. This is at 1280x1024 on the 9.3 drivers. Reproducible with both OpenGL 2.1 and 3.0 contexts.

    As pointed out above, fglrx has excellent 3d performance. Video and compiz are the workloads it struggles with, which is understandable given the workstation background of the driver.

    Just my two cents, with my NVIDIA card I don't pay attention to releases because it works correctly, with my ATI/AMD card in my laptop I keep on hoping that they fix my long standing issues.

    At this point, I can't recommend ATI to anyone running Linux.

    So am I, fact that they are getting identical performance is more then likely that you are cpu limited with those titles and not hitting a GPU bottleneck. Those games really don't push the video card much.

    Ultimate preset. Only settings on CCC being forced on both OS' are mipmaps (High) and Catalyst AI (Advanced). Latest end-user drivers.
    Alien Arena performs identical on both OS' with the same settings. The same goes for Urban Terror and Warsow. Furmark (running under Wine in Ubuntu) gives out the same scores.

    Fglrx has good 3D performance. No surprise really. Where it sucks is in common desktop situations, specially when you try to accelerate them. Again, no surprise given where the driver comes from. These issues are being worked on. Sure, even I would like all these things fixed as quickly as possible, but given that the codebase is rather "new", the delays are understandable.

    Drop you CPU clock by 20% and compare to your current results. Then clock your CPU back up, hen drop your vid card clocks by 20% and re-test and compare. I'm pretty sure you will find that your CPU is what is holding you back on Urban, Nexiuz and Warsow when your only running @ your 1680 res.

    That's not surprising. Nexiuz isn't exactly a game that pushes systems hard.
