That only confirms MirekCz''s suspicion that it is a fill-rate problem. The Radeon has a lot of fill-rate to spare and won''t buckle under a few pixels more or less. But the Vanta has far less, so it will make a lot of difference whether you draw pixels or not.

Is there any way to combat the fill-rate problem, other than buying a new video card? I mean all I am doing is drawing a single textured quad, how hard can that be on the video card? Can''t the rate at which pixels are drawn to video memory handle one textured quad?
Or, do you think that the 16mb TNT2 Vanta AGP is just to out of date for modern times, and I should get a new 32mb or 64mb GeForce3?

i had a problem something like this when i started using Directx on my 1.0ghz comp w/ Voodoo 5. I could get over 200 fps in 800x600x8, but only 4 fps at 800x600x16. It really ticked me off for a while, but the some1 told me how to fix it. there was something wierd w/ the anti aliasing on my voodoo, and i had to change some obscure setting to get the framerate to go back up in 16 bit mode. maybe that will help ya some.

You had it right when you said your TNT2 Vanta is out of date. That's my opinion at least. TNT2 is pretty old now, and the Vanta was the budget version of that chipset so I'd say that's your bottleneck... When I upgraded from a Voodoo3 3000 AGP to a Radeon 64 DDR, the difference, on the same hardware, was incredible.

I have A 8 meg Vanta LT. I think it is the bottle Neck in my system. I have a 800 tbird, old proc.
I use opengl, but everyone also has the dx sdk. In the 3d8 sdk sample on billboarding I get around 22 fps. Thats really low but games run fine.
Is this normall for my card?
