Xfree86+GLX vs AccelX on a Matrox G450

[bunty]

Hi there.

I just setup X4.0.2 with GLX support for my Matrox G450 cards.

I have compiled the gears deme to use as a benchmark.

I am getting 146FPS maximum for the gears demo in Xfree86.

.

Now I downlaoded the AccelX 3D LGD for linux and installed it.

I dont have any GL based benchmark testers.

Can you all point me to some OpenGL benchmark testers for Linux.

Thank You.

Machine specs

Dual 800P3 with 512MB ram Matrox G450 Dual Head with 32mb .

[rts]

I also have a dual PIII 800 w/ 1 GB of RAM and a Matrox G450.

I get 146 fps with gears, default window size, in software mode.

I get on the order of 600 fps with gears, default window size with DRI enabled.

Are you sure you have DRI enabled? Or did you resize the gears window to something much bigger than the default?

I just recompiled X and the new g450 drivers and I even used -march=pentiumpro.

Enabled dri and I'm up to 150fps in the gears demo at the normal size.

Do you do anything abnormally ?

This is what I get from glxinfo:

To the top I notice it says :

direct rendering: No

I assume it should say yes.

What does your glxinfo return ?

I read the docs and did what they said.

this is the glx/dri section in my /etc/X11/XF86Config :

...
# This loads the GLX module
Load "glx"
# This Loads the DRI module
Load "dri"
EndSection

Section "DRI"
Mode 0666
EndSection

What am I doing wrong ?

I also loaded the mga.o module for the kernel whcih I built from within the X source.

[bunty]

Ok. I captured the output from X and logged it. The first thing I notice is that it said that it only does direct rendering in 16 or 32 bit modes. So I changed my colour dept to 16bpp.

Welp my fps is up to 179fps, but I'm affraid dri is still not working.

Here is my X output.

Does anyone know what I'm doing wrong ?
Any help will be greatly appreciated.

Make sure you are using the latest mga.o kernel module and the agpgart.o kernel module.

Lots more help available at Matrox Tech Support .

[bunty]

ok, the matrox docs said to build one from X.

I have kernel 2.4.1.

Now I have agpgart built into the kernel.
Should I take it out and use a module instead ?

I will attempt it with modules. Thanks
I'll remove the mga module i built from X.

Thanks

[bunty]

Ok, that's a no go on the kernel modules

Yeah... that's what I meant. Build the mga.o in X (it lives in xc/programs/Xserver/hw/os-support/linux) and install it.

Now I have agpgart built into the kernel.
Should I take it out and use a module instead ?

Matter of taste, I think.

Anyways, like I said, check out the Matrox Forum, lots of help in there.
