ATI Rage XL should support OpenGL 1.1 due specs, even 2.0.

IIRC ATI Rage GL drivers should be an ICD part of the driver, not MiniGLs. There could also be a newer DirectX dependency involved as well (486s can't install DX8)

OpenGL 2.0 is for shader model 2 hardware and better (Radeon R300 9xxx/GeforceFX)

Shall I install Windows 98? how 486 connected with software part? Yea, it could be slow, but should run it.

I don't understand this(IIRC - ? ICD -? ). Could you explain where I can get correct opengl32.dll? or install some correct driver or check it somehow?

Rage II and up, ATI was specifying Pentium II minimum, but it was working on other MMX class CPUs.

If you want any working, performant GLQuake on a 486, you're best using a 3dfx Voodoo Graphics / Voodoo2 for the least driver overhead (plus v2's multitexturing should be more comfortable on data going through the bus, despite the 'your wasting VooDoo!' bottleneck arguments). Quake2 may be a no-go for cache reasons (it's more heavy on the sound work and model animation, and 3d acceleration won't help you there.)

I don't understand this. How CPU connected with GPU? Code has instructions, driver transforms them to hardware - run and go, yea 486 can slow down on some mp3 or engine calculations - eg gravity or objects, but grafics must work.

I think this is software problem and I need to have correct software. Additional instructions on CPU does not connected to graphics performance from my point of view.

In the early "GPU" days, the CPU does all of the load-bearing on the driver, especially the FPU. The GPU just handles texture mapping, fog, and blending mostly. On ATI Rage this is worse as the alpha blending is also software rendered (this is where the P2 recommendation comes in).

You can squeeze 16-17 fps from Quake 2, but without sound, with some tweaks and on heavily overclocked 486DX4 with 3dfx card.

As a baseline of sorts, an AMD Athlon XP 1800+ @ 2166 MHz (12x 180) gets about 32fps in GLQuake and 29fps in Quake 2 using a Rage XL at 640x480 in 16-bit color . I wouldn't set my hopes too high for a 486 at 133MHz with the same video card.

486 is my favourite wolfenstein machine especially where no usb or ethernet i dont recommend overclock such old vintage just to say i can quake 2 only last hours before death unless under refridgeration. there is the 250mhz cpu but still not enough for quake

I have tried this with a Cx5x86 and Riva128 and I can tell you that you DON'T want to do it. Just get a Voodoo 1 or 2 if you want hardware 3D on a 486. Better still, just don't do it 🤣

I believe that it is possible. I will install windows 98 + directx + opengl libs. This an experiment - I want to prove that it is possible.

You may need a p24t to get around drivers targeting pentium only

No one's saying it's impossible to run GLQuake and Quake2 on a 486. It's just not feasible with the Rage family. It's also not feasible with any PowerVR card either. It IS feasible with 3dfx Voodoos however...

also a spoiler: Quake3 can run on a 486 too. Barely, but it's possible. Feasible the hell it isn't.

Yeah, I thought for about 1 minute that I might throw my Voodoo 3 in my Cx5x86 just for shits....then I thought better of it. 🤣

If I didn't completely imagine picking up an 8MB V2 some years ago, and if I find it, it's not beyond bounds of the possible that it might take a spin in a fast 486 machine here, but got plenty of super 7 stuff that will use the 16Mbs and the V3s better.

I don't want to buy voodoo. They are expensive and quake 1 on voodoo ~ 17 fps on 640x480. This is too low for dream pc from our childhood.

Ok, any other solutions except voodoo and rage that will run opengl?

I have pci usb card, so it will have usb.

Sounds like you need a read of this thread... Modern graphics on a 486

Quake heavily uses the FPU. 486s won't stop having a weak FPU and 3D accelerators will never ever hope to overcome that.
