GeForce 7600 Go too slow

Hi,
i recently switched back to Arch-Linux from Ubuntu but now i get only 2000 fps when running glxgears (in Ubuntu i had 4000). Does anyone have a clue what may be the cause of this?

Re: GeForce 7600 Go too slow

Post the output from

grep -v "^#" /etc/X11/xorg.conf

edit: I got 12,000 fps on a GT7600 in an AMD64 3800

Re: GeForce 7600 Go too slow

@Issue: I know that glxgears is not a benchmark but i tested it with ut2004 too and got about 50 fps less.

I have glx loaded and the nvidia driver starts so i think it is not an configuration problem of the x-server. But here is the device-section output of the regular expression
Section "Device"
    Identifier  "nv73"
    Driver      "nvidia"
        # unsupported card
    #VideoRam    262144
    # Insert Clocks lines here if appropriate
EndSection

And this is the Output of nvclock:

Re: GeForce 7600 Go too slow

I assume you have direct rendering

glxinfo | grep rendering

Any errors or interesting warnings in the X server log file (probably Xorg.0.log)?

cat /var/log/Xorg.0.log | grep "WW\|EE"

Re: GeForce 7600 Go too slow

Direct rendering is enabled

That´s the output from the xorg error log:

(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(WW) `fonts.dir' not found (or not valid) in "/usr/share/fonts/100dpi".
(WW) `fonts.dir' not found (or not valid) in "/usr/share/fonts/75dpi".
(WW) Open ACPI failed (/var/run/acpid.socket) (No such file or directory)
(II) Loading extension MIT-SCREEN-SAVER

Could it be that acpi throttles the card down to save battery-life?

Re: GeForce 7600 Go too slow

have you got windows installed on that machine? if yes, start windows and reset powermizer settings to default and reboot

Re: GeForce 7600 Go too slow

I don't have access to the GT7600 PC, but my FX5200 gives these warnings

(WW) `fonts.dir' not found (or not valid) in "/usr/share/fonts/100dpi".
(WW) Open ACPI failed (/var/run/acpid.socket) (No such file or directory)

but runs fine giving me 1300fps in glxgears with 24bit colour. With DRI off I get 200.

Re: GeForce 7600 Go too slow

Is direct rendering the same as

Option "RenderAccel" "true"

in the device section? I can't remember they enabled that by default...

Re: GeForce 7600 Go too slow

Rebooting in Windows and setting the power settings to max didn´t work.
RenderAccel isn´t related to glx afaik so it doesn´t boost fps.
Does Pci-E support SBA and FastWrites? Maybe that is the cause because they are both deactivated.

Re: GeForce 7600 Go too slow

The only thing I know that really improves the glx performance is decreasing the screen depth from 24 to 16, but I don't know if Ubuntu is using 16 by default...

Re: GeForce 7600 Go too slow

It seems that my Ubuntu set the screen depth to 16....

Anyways now i get the 4000 fps as shown in Ubuntu so thx to everyone who helped
