How the TurboGL works...

[Kruzin]

Just to keep everyone on top of how/what the TurboGL does...

When installing the drivers, your processor will be detected. If you have a P3 or K7, your machine qualifies for the TurboGL MCD.

During the rest of the installation, your hard drives will be searched for games supported by the MCD. When it finds one, it will unpack a file called opengl32.dll into the appropriate game directory. At that point, just selecting OpenGL from the game's options is all you need to do.

DO NOT put this opengl32.dll file in your windows\system directory!!! The stock windows opengl32.dll is required for the regular ICD to work.

If you do not want to use the MCD for whatever reason, just go to the game's directory, and delete opengl32.dll. Then the regular windows ICD will be used.

If you have a Voodoo card in your system, you WILL have problems with the TurboGL MCD. It won't work with a voodoo card in the system.
You can:
(a)delete opengl32.dll from the game folder to use the regular ICD.
(b)remove the voodoo card and drivers from the system to use the TurboGL MCD.
(c)install the 3dfx MCD over the TurboGL MCD to use the voodoo for the game.

Kruzin as brilliant as always I couldn't get the download but your there as always telling people what to do.
Anyway I'm pissed and I'm going to be pissed tomorrow having a good laugth.
Anyway whats this Voodoo sounds like a good drink to me.

Hey Kruzin, I'm just a little bit confused. Are you saying that the Turbo GL MCD for the Matrox will not work properly on the G400 Max if I have a V3 2000 pci as a secondary adapter?


Thanx...

....Tessen....

If you have a Voodoo card in your system, you WILL have problems with the TurboGL MCD. It won't work with a voodoo card in the system.

Pretty clear, No VooDoo's period. SOme claim to have gotten them to work. But officially, they do not. Sorry.

Not sure if this is the answer but PD5.30 is not optimized for DX7.

If that was ref. the lack of paletted textures, I checked earlier with DX6 capsviewer, and the paletted textures were still missing

Why does the G400 TurboGL driver not work on a system with Voodoo cards installed? What is the technical reason? My attempts to use the TurboGL driver just caused my system to crash, while the normal ICD runs fine.
I need to keep my Voodoo² cards in my machine for development purposes, yet it would be nice to use the TurboGL driver for my newly acquired G400 MAX.
I've just disabled DirectDraw/Direct3D on my Voodoo² cards, will that help? I guess I'll try again and see.

While I'm thinking of development, why does the G400 not support PAL4 and PAL8 textures with the latest PD 5.30 drivers [according to DX7 capsviewer]? Is this a bug in the driver? One of the things that attracted me to the G400 was the fact that it did alpha values in texture palettes, something I wanted to exploit

Kruzin:

I just threw a P3 450 in my machine, replacing a P2 350. Do I need to re-installed the G400 drivers to get the Turbo-GL to work?

[Kruzin]

No. In the folder you unzipped the drivers into is a .exe call PDGLutil.exe. Just run this...

[The Rock]

Kruzin:

Thanks. The file didn't work; apparently, I need to reinstall the drivers, but that isn't a problem. Wonder if Unreal's hideous OpenGL will actually improve with this.

Take the file called mgatglp3.dll and copy it to your WINDOWS/SYSTEM directory. Rename it MGATURBO.DLL, and then run PDGLutil.exe. That should do it.
For K7 owners, the file to use is mgatglk7.dll.

Note: even with D3D disabled on my Voodoo² cards, the TurboGL driver still hangs on my system

[IceStorm]

Yer system's weird.

Mine works fine with the reference drivers from 3dfx. :-)

From the above posts, it looks like TurboGL with Voodoo works as long as you don't have the 3dfx ICD installed. Correct? I don't see any reason why 3dfx minigl drivers would cause problems.

[IceStorm]

Why would you install the 3dfx ICD?

Even if you did, they could co-exist, as long as you remove (backup) the files prior to trying to run the G400's ICD, and do the same for the G400 when trying the V2's ICD.
