I have a diamond stealth video 2500 (Alliance AT24). Can't find much info on this chip. Any info or opinions? I'm guessing this was mostly a good win3.1 win 95 "multimedia" PC card. Not really a gaming chip?

DirectX 3D on this thing? That is something I need to see. This looks like a pure 2d card

AT25 is quite common on Rush. Never seen AT24 on one.

Sound strange also to me that Direct3D was supported, maybe just an optimistic press release style or something like the old Voodoo 3 "DVD playback assist".......as other said I rememberd also the AT3D as 3D "accelerator".

I have the exact same card, upgraded to 2 MB (I think, can someone explain how these memory chips' sizes work? e.g. 128kx8) with two 256kx16 EDO chips. Haven't really used it much past the 2D card in my now-defunct Voodoo2 build.
