Just a guess: Set your desktop to 16 bit color depth.

Hi,

Already tried with the same result.

In Windows\System folder I just checked the presence of the opengl32.dll file.

Try a different driver set, or another version of Quake 2? Test the demo using OpenGL, or patch to a new or older version. Possibly try reinstalling?

I actually ran Q2/default OGL with a v330 pci (430TX), back in the day. So I know it should be possible. Does D3D at least work?

Hi,

D3D is working fine, I tested it within dxdiag.
I tried Diamond official drivers (i don't remember reversion number) and I had the same problem.
Maybe I can try a set of driver older than 3.37.

M.

This is almost a coincidence as I was having major probs getting opengl to work in Q2 with a Intel i740, but in that case it was the
fact that I was using a 24bit desktop depth, 16bit fixed that.

Maybe check out Philscomputerlab's Youtube video on the Riva 128.
I actually purchased the exact same Diamond v330 as You just last night, so will give it a shot when I get it.

Hi,

I've tried a different set of NVIDIA drivers (v2.77 reference)

I've also installed AGP drivers v4.35 as stated here

Recently I had a few Via 4in1 4.35 driver issues with my Gigabyte GA-6VXE7+ Rev 3.0 Via Apollo Pro board. I found that every time I installed the 4in1 drivers, I would encounter problem after problem. Mainly Windows 98 SE start up issues but also several AGP related issues. I then went into device manager and updated the "VIA CPU to AGP controller" under "System Devices" with the Viagart.vxd driver found in the AGP folder of the 4in1 4.35 drivers and my graphics card/start up issues were gone. Also graphics card performance improved by around 50%. Went from 3379 to 6385 points in 3DMark 2001SE. Who knows, may help you too 😀

Oh and before you go reinstalling Windows 98 for whatever reason, boot into "safe mode with command prompt" and go to the Windows\Command directory and enter "scanreg /restore". This will restore your registry to the last known error free start up point also avoiding any other problems the 4in1 drivers created for you. Then just reinstall your drivers again. Better than waiting around for Windows 98 to install again.

Nothing, when I chose Default OpenGL, Q2 gives a white screen.

D3D and DirectDraw testing within DXDIAG perfectly working.

goes glquake run ?
try glmark and glclock to make sure your opengl drivers work

Have you tried removing the opengl32.dll in the quake2 directory in order to force it to use the system's default dll? I kinda remember doing that at some point...

Hi guys,

There isn't any opengl32.dll in Q2 folder.
I reinstalled everything from scratch and now Riva 128 works fine with Default OpenGL Q2 drivers and 3.37 NVIDIA reference drivers, obtaining ~20FPS with a Pentium 233 MMX.

Anyway I'm pretty sure that VIA 4 in 1 drivers installer is bugged: even if I install the package (v4.35) on a Win98SE fresh install, it actually doesn't install provided drivers. In fact Win98SE device manager reports that VIA components (AGP, CPU to PCI and CPU to ISA bridges) are still using Microsoft OEM drivers.
I've to install VIA AGP drivers manually as stated in a previous post, leaving CPU to PCI and CPU to ISA bridges with Microsoft drivers.

After solving Riva 128 OpenGL problems, this time is the turn of the Matrox M3D 🤣

Anyway, PMMX 233 is clearly too slow to drive both the Riva 128 and the PowerVR PCX2 cards.

I'm planning to change platform, going for a PII 400.

M.

Matrox quake 2 drivers
https://www.matrox.com/graphics/cs/support/dr … les/w9x_m3d.php

Those drivers are really useless as Q2 ships with a newer version of the MiniGL

Yeah that's right.
Anyway this time I have problem installing PowerVR drivers. After install process, even though the card appears in device manager, I haven't any control panel in Display Properties.
I think that's a resource problem.
What do you think about Via 4 in 1 installer bug?

M.

It appears to me that Q2 picture quality using Riva 128 OGL is better/cleaner than the 3dfx one.

Isn't it?

M.

It may appear more crisp under any circumstances, since their texture filter is rather lazy. 3dfx on the other hand comes out with strongly blurred textures.

TBH I prefer NVIDIA picture quality. 😁

Anyway, I changed platform going for a Pentium II 400@448MHz, Riva TNT, V2-SLI and the infamous Matrox M3D.

The FPS gain using the PowerVR OpenGL is fairly modest in Q2 timedemo 1: just 22FPs with the Pentium II@400MHz.

I was pretty sure that a stronger FPU than a PMMX@233 would deliver a better frame-per-second score. Well, I was wrong.

I could also see that the PMMX performance in Quake 2 is very similar to that of a K6-233. I've read many reviews that claim the FPU superiority of the Intel CPU, but the substantial level of performance (using both the Riva and the Voodoo 1, less with Matrox) surprised me.

M.

The issue with the Riva128 is its poor blending precision with subtractive/modulated blending functions making some really banded lightmaps. Riva128 looks better in vertex-lighting only games (i.e. not Quake or Quake2 or Unreal or anything else influenced by Quake)

PowerVR also has its own issues with the lightmaps, being alpha-blended and the texels having noticably blocky filtering. It's a brighter and less saturated game at least 😀
