Nice. Will give it a try soon

I'm getting this error:

Same error happens with D3D8 rendering as well. OpenGL works fine and original D3D gives me speed issues (game runs too fast). The card is a GTX460 with latest drivers on Win7 32 bits. Unreal is patched to latest 227. Any clues?

I decided to compare Glide performance on a couple of systems with a big difference in computing power.

System 1: Celeron 466 (66 MHz FSB) with Voodoo 3 3000 (AGP) / AWE64 Gold / 192MB PC100 SDRAM
System 2: P3 866 (133 FSB) with Voodoo 3 3000 (AGP & PCI) / SB Live! Value / 384MB PC133 SDRAM

At 1600x1200, both systems clocked in at 26.8 FPS in the castle timedemo. System 2 pumped out 8.2 FPS at the same resolution with a Geforce 4 Ti4600 (not sure if D3D or OGL -- how do you tell?)

I also have a Voodoo 3 2000 PCI card, so I overlocked it to 166 MHz and came up with almost the same framerate, 26.9. I know that Voodoo 3 was not a "true" AGP card, but I was surprised that the result was almost exactly the same.

I'm still really surprised by how much better Glide is than D3D/OGL for Unreal engine games.

1600x1200 is just too much for a Voodoo 3 to handle (it's fillrate-limited), that's why you get the same fps. If you lower resolution to a more reasonable 1024x768 then you'll see some differences in performance. The GF4 is probably Direct3D, that's what Unreal Gold selects by default (look in Options/Preferences/Video tab to see what renderer is being used).

The Unreal Engine was designed with Glide in mind from the start. Direct3D/OpenGL were added later as an afterthought, Epic never did properly finish the renderers so they could provide performance and visuals as good as Glide.

Done some Voodoo benching a while ago:

Details about the system used and other benchmarks can be found here: http://www.philscomputerlab.com/3dfx-voodoo-s … ut-project.html

I play UNREAL with my PII-333 with a Voodoo3 and it runs quite well in 1024x768.
There was an "optimal" Version for the GLIDE-Support. The latest Version does not
run best on GLIDE. I don't know which Version it was.

There were major differences in the quality of lightning and colorpalette.
I don't find the Version and the sample Screenshots yet.

I'm often told 225f is the version to play with Glide but I have a pentium 3 system with voodoo 2 SLI downstairs that get's major FPS tanks whenever elaborate dynamic lighting occurs or multiple fire textures show up.

Thanks! Very well done and quite helpful.
