Hi everyone,
yesterday I used fsarchiver and restored my laptop back to januar 2011

using Applications/System Tools/System Profiler and Benchmark
and in its Display I saw that my OpenGL version is 2.1 Mesa 7.7.1

after using these 3 commands(from omns) to upgrade my graphics driver

sudo apt-get purge xserver-xorg-video-nouveau xserver-xorg-video-nv
sudo apt-get install libgl1-mesa-dri libgl1-mesa-glx
sudo dpkg-reconfigure xserver-xorg

I got OpenGL version 2.1 Mesa 7.10.3-3
(after update)
ace@ace-laptop ~ $ glxgears
300 frames in 5.0 seconds = 59.985 FPS
299 frames in 5.0 seconds = 59.878 FPS

(before update) OpenGL version 2.1 MEsa 7.7.1
ace@ace-laptop ~ $ glxgears
2072 frames in 5.0 seconds = 414.371 FPS
1961 frames in 5.0 seconds = 392.153 FPS

as you can see my fps drops so hard.
some months ago I did the same and got OpenGL version 2.1 Mesa 7.10****
and I am sure my fps at that time was even higher than before update*

are there any ways to install Mesa 7.10 or 7.10.2 instead of 7.10.3-3?

1) glxgears is not a benchmark
2) your'e geting 300 fps because of the VSync - use driconf / .drirc to turn it off

Hi sumski,
I installed driconf (sudo apt-get install driconf)
and run it (driconf / .drirc) and got that screenshot.
I changed the option where the mouse cursor is at to "never synchronize with vertical refresh, ignore application's choice"

and I still get 300 tps. (also tried to restart the laptop and also with sudo driconf / .drirc)

should I run driconf as root?
did I change the right option?
do I need to restart the laptop ?

replace contents of your ~/.drirc with this:

Code: Select all

<driconf>
    <device screen="0" driver="dri2">
        <application name="Default">
            <option name="vblank_mode" value="0" />
        </application>
    </device>
</driconf>

it works, now I have 500 fps instead of 60

2442 frames in 5.0 seconds = 487.989 FPS

thank you very much sumski
