    Phoronix: Nouveau Driver Remains Much Slower Than NVIDIA's Official Driver

    While benchmarks this week have shown the Nouveau driver can be faster with the Linux 3.8 kernel, further benchmarks have shown that this reverse-engineered open-source driver for supporting the spectrum of NVIDIA GPUs is still at a significant loss compared to NVIDIA's official but proprietary Linux graphics driver.

    And make sure that you are relly using binary driver: glxinfo | grep -i -A 5 -B 5 NVIDIA
    Oh and what version of driver are you using: cat /proc/driver/nvidia/version
    There was performance issues at least some of 295.xx branch drivers.

    i have this problem in both unity 2d and 3d. also i had same problem in openSUSE and KDE. i tried many nvidia binary versions 173, 295, 304 etc but the problem did not solve.

    the problem is that my laptop works good with nouveau driver in ubuntu 12.04 with unity 2d; but when i activate nvidia binary driver to enhance the performance and to use unity 3d, the performance shrinks severely, in fact, performance of my laptop with nvidia driver is much weaker than nouveau. for example when i run "glxgears" command in ubuntu with nouveau driver, the resaults are almost between 320 to 420 but if i run same command when nvidia binary driver is activated, the resaults shrink severely and are almost between 50 to 63. i had this problem in both ubuntu and befor that in openSUSE. also i tried different versions of Nvidia binary drivers but the problem exist with all of them.

    i tried to solve this problem with asking about it in ubuntu forums (here), openSUSE forums (here) and many other linux forums but unfortunately i found nothing useful.

    So, here is my last chance to find what is the problem with my graphic card and how solve that. please help me.
    thank you.

    And make sure that you are really using binary driver: glxinfo | grep -i -A 5 -B 5 NVIDIA

    poor performance of nvidia driver in my laptop

    sure it does
    on many levels

    but honestly for one of the main xorg devs to take so long to realize that everything should be a buffer tells a couple things too

    There's still a bit truth to it. Try using the window management a bit with a geforce 6600 (!) and xfce, even with compositing. It just feels right.

    painting a window and resizing it at the same time is not a trivial operation, in fact its bloody complicated and needs lots of bandwidth


    also you can all bash on OSS drivers but the truth is if they dont suit you either dont use them or get your hands dirty
    complaining on some forum or another is useless and annoying

    if you are not suited to code them, like i am not, best you can do is file bug reports (ofc check if your setup is good and if the bug is already filed)

    So, after Linux devs, now xorg devs are also morons. Everybody who makes your software is a moron.

    What do you call a user using software written by morons then?
