That's right for dual SLI 12MB cards - 4MB frame buffer memory + 8MB texture memory, SLI detected

For some people it shows 8 and 16 though , which is why I'm kinda confused.

Uhm... it's not. With two 12 MB cards in SLI, there should be 16 MB of total texture memory and 8 MB of frame buffer memory (which adds up to 24 MB).

Is that with official or modded driver? because those numbers are basically a scam.

That's with official drivers (though, as far as I remember, I saw the same numbers with the FastVoodoo drivers).
Why do you say it's a scam? I mean, the whole reason why 1024 x 768 works in SLI is because of the increased frame buffer memory. And since each card only renders half the lines, the texture memory is also effectively doubled.

Edit: on second thought, it's very possible that this is a visual glitch with the FastVoodoo drivers, while the official drivers show the correct numbers.

To the OP: as long as the benchmark results are good (and 1024 x 768 works as expected even in games that use Z-Buffering), you should disregard what that properties page says. 😀

8MB of framebuffer memory is correct. 16 MB of texture isn't. Effectively, there is only 4 MB of texture memory.

4MB per TMU precisely and SLI won't actually improve the situation with texture thrashing.

Local framebuffer usage decreases from 800x600x2 to 1024x384x2, you could see this as doubling framebuffer, but:

Both cards must load same textures. In effect you can see this as either double texture memory with textures loaded twice, or no texture memory doubling.

This "glitch" unsurprisingly smells like someones idea for driver tuning.

So what would be a good game to test with , would quake 3 do the job?

Unreal/Unreal Tournament 99 both have native Glide SLI support and will use it if its present and working.

True, those are all very valid points. 😀

Here are a few benchmarks I did on a Pentium 3 Coppermine @ 868 MHz / FSB 124 MHz, with 2 x Creative Voodoo 2 12 MB running in SLI:

GLQuake Voodoo 2 SLI: 640 x 480 x 16: 183.5 FPS
GLQuake Voodoo 2 SLI: 1024 x 768 x 16: 82.2 FPS
Quake 2 Voodoo 2 SLI: 640 x 480 x 16: 144.1 FPS
Quake 2 Voodoo 2 SLI: 1024 x 768 x 16: 68.8 FPS
Quake 3 Voodoo 2 SLI: 640 x 480 x 16: 72.8 FPS
Quake 3 Voodoo 2 SLI: 1024 x 768 x 16: 37.3 FPS

You can compare these to your own results. Even with much slower CPUs you should see similar numbers.

I just tested unreal and it ran in 1024x786 fine so I guess the display setting just displays wrong info for some reason?
