I made that video, fun that people play around with mtgl32!
Tough I did not write the actual SMP patch (found it on internet archives), just made some changes to the quake3 source to allow people to select it from the menu.
Also added 8 and 11Khz audio support but it can sound bad during movies and timedemos from my testing (mainly ISA cards) but its MUCH faster on CPU limited machines.
And you can select quality in the menu now, it was previously useless and broken.
Also VC2005 was used to generate faster binarys with optimized compiler flags.
Was told Quake 3 dont have high and low pass filters and thats why its hardcoded by default to 22Khz (the code for 11Khz is actually there just commented out.
A modern port, Quake3e has those filters the dev told me.

mtgl32.dll works on other games when my friend tested, half-life for example, as long as you can call the driver using r_gldriver or similar it can work.
I think he got gains in Quake2 also, need to test myself.
Wolfenstine tough had performance regression for me.

You can get the 3 versions of mtgl32.dll I have found plus the manual from my dropbox, I think its all on internet archive somewhere if you know where to look that is XD

Anyways was going to register on the forum anyways because I got an SGI Octane last month so I have watched your IRIX install Howtos!
I've re-installed my Voodoo5 5500 into my dual PIII system and I simply cannot get it to work in SMP mode! Do you by any chance know if it's possible to overcome this problem?

I've installed the Quadro 2 Pro, and I must admit that the results are underwhelming to say the least!!!!

Here's the Nvidia Driver setup:



Here's the 3DMark 2001 score:



Here's the standard Quake III TimeDemo Four result:



Here's the Quake III SMP TimeDemo Four result: (Slightly lower than the standard version!)



For comparative purposes, here's the GT 430's 3DMark 2001 score:



Here's the GT 430's standard Quake III TimeDemo Four result:



And here's the GT 430's SMP Quake III TimeDemo Four result:

Here's what the Quadro 2 Pro looks like in the machine:



I should hopefully have the Quadro 3000 in the next couple of weeks, so let's wait and see as to how that card performs! But for now, the ZOTAC GT 430 PCI is the best card I've tested in this system by a pretty large margin!
