Not true eh? Well, try this. Create a model like a 9x9 terrain. Now give a simple 2048x2048 texture on each of a set of 2 faces. This would be about 4 megapixels. Since you have 64 areas where this can go, that's 256 megapixels. If your card does 2 gigapixels per second, you'd need about 8 of these to get 1 fps.
In my experiment, I used a 2 megapixel texture on a 4-poly object (a square pyramid without the base) and I had 27 of these on screen. This is 54 megapixels worth of objects. From the ATI website, my card has a fill rate of 2 gigapixels per second. Taking 2048รท54 and you get about 37.9. I was running at 60 fps (the "maxed fps" note), explain that. I'll run it again if you want and I'll find the maximum.
