Hi there, I am a bit confused about my Acer V66LT Board with ATI 3D Rage Pro LT.
Are there drivers for Win3x? I could not find them and the WFW3.11 Vesa 256Color-Driver does not work too ;( (corrupted screen)
Beside that I am wondering why in win9x there is only D3D but not OpenGL-Support.

What drivers should I use, especially if I would like to play some really old "ATI3DCIF" stuff too.

Thx!

RAGE LT (laptop) and RAGE LT Pro (desktop)[edit]

Rage LT chip

ATI Rage LT Pro AGP, 8 MB SDRAM
Rage LT or Mach64 LT was often implemented on motherboards and in mobile applications like notebook computers. This late 1996 chip was very similar to the Rage II and supported the same application coding. It integrated a low-voltage differential signaling (LVDS) transmitter for notebook LCDs and advanced power management (block-by-block power control). The RAGE LT PRO, based on the 3D RAGE PRO, was the very first mobile GPU to use AGP.

It offered Filtered Ratiometric Expansion, which automatically adjusted images to full-screen size. ATI's ImpacTV2+ is integrated with the RAGE LT PRO chip to support multi-screen viewing; i.e., simultaneous outputs to TV, CRT and LCD. In addition, the RAGE LT PRO can drive two displays with different images and/or refresh rates with the use of integrated dual, independent CRT controllers.

The Rage LT Pro was often used in desktop video cards that had a VESA Digital Flat Panel port to drive some desktop LCD monitors digitally.

After ATI stopped producing the RAGE LT, ATI used the Rage 128 and Rage 128 Pro as the base chip for their new Mobility Mobile Graphics.

ATI3DCIF.DLL collection http://vogonsdrivers.com/getfile.php?fileid=498&menustate=0

Rage LT Pro fully supported from 4.10.2661

https://gona.mactar.hu/ATI_3D_CIF/#Severe

MechWarrior 2 and TombRaider are working on Rage LT Pro up to 4.11.2573 (MACXW4)

2661 vs. 2573 ? strange? Higher versions 26xx seem to break everything on ATI3DCIF?

http://www.oocities.org/ziyadhosein/rprow98.htm

But higher versions do have an opengl driver ? So I am stuck in a compatibility dilemma?

This is the driver I am using. It has opengl-icd included and it works in D3D too.

I have to try ATI3DCIF next!

Interestingly my OSDM files do work (if DX7 is loaded), that was pretty unexpected...

I do not have tested it because it's a dx8.1 driver and according to this, it does not support or broke ATI3DCIF. https://gona.mactar.hu/ATI_3D_CIF/

One thing is the very bad image quality on textures in opengl on that ATI-Rage-Pro LT...
and also some textures "alpha" are not filtered and look blocky...

Hm, win3x does not work on Rage Pro LT... I only can use VGA 640x480@16colors.
If I choose SVGA 256colors the screen is currupted and I see only some lines on top of the screen.
If I install the mach64 win3x drivers I only get some moving lines on the screen...so that is pretty bad because a r7000 works just fine with svga-drivers.

Any Idea what I can do to get 256colors in Win3x?

Mach64 Driver does not work on Rage Pro, it should work on pre "Rage Pro".
Rage II, Rage I, Rage IIC etc.

So no way getting 256colors?

There is one wild idea. Would it be possible to install Windows 2000 on that machine? I think there are proper W2K drivers for ATI 3D Rage Pro LT (to be checked). Then, you could use Virtual PC 2004 to install Win3x, and get 24-bit color thru the emulated S3 Trio64 video card.

Interesting idea, but the machine will be too slow for that...but I think I can patch the WFW-Drivers with vesa, so it should work...I'll test this in the next weeks. Currently working on my G4-Cube.
