We can only help if you give us some information.
What are your system specs?
What OS do you run?
What are your IRQ assignments?
What game(s) are you having trouble with?

Give us something to work with, and we'll get ya running

[Kirill]

My specs are: Pentium II 266 128MB Matrox G400 not Max, Windows 98. Drivers 5.52 Turbo GL 1,30,0,2
I cannot run any Open GL games! I had the same prob. long time ago but i found an answer in your forums (it was a very simple solution), but i have formated my comp, and all settings have been erased. (I think something should be changed in my settings but I don’t remember what)

I would really appreciate your help!

Thanks in advance!

To start with the basics...
Make sure the G400 has an IRQ assigned to it in the BIOS (IRQ 9 or higher). It (plus an IRQ steering) should have that IRQ to itself.

Set desktop to 16 or 32 bit color. 24bit will not work.

Turn off DualHead Multi-display mode. OpenGL does not support more than one display (clone/DVDMax will work).

True, it won't support the second head but it doesn't prevent you from playing on the primary head ... done it many times, by accident.

[Kruzin]

Then you are probably using TurboGL. TGL will work with the second head activated...straight OGL won't (in WIN9x at least)

True, I'm using TurboGL w.5.52, but so is Kirill. Hadn't tried w/ the full ICD.

I have checked my settings and that's what i have got:
Dual head - disabled
IRQ 11
But still i cannot play any Open GL games, i cannot even use GL screen saver!
Please help

I had similar problems once, d3d work, but ogl - not
Check your motherboard bios settings, esp.- agp aperture size(your cart is agp?). default values should work, if not - try 128mb or bigger...

Use Matrox' uninstaller to get rid of PD5.x and go for PD6.x instead ...

No need for TurboGL anymore.

Ha Bud, had the exact same problem with the 5.52's the same day I bought my card (G400 32MB SH) After experimenting and trying different thing's I had a flashback of my old S3 turmoils. Figured out it was the 130 TurboGL drivers. I went to all my OpenGL game folders and deleted the OpenGL32.dll files (make sure its the Matrox Driver files; right click on file/properties). All of my OpenGL Games fired right up with no problems. Also your OpenGL games won't run if your DeskTop is in 24Bit Colors. Use only 16 or 32Bit. Then only game I found TurboGL to run for me in OpenGL was Half Life, in which the TurboGL installer installed it in the wrong folder. It belongs in the Half Life/gldrv folder.
