I've been messing around with using hi-res (512x512) textures, replacing 64x64 ones, and the frame rates plummet through the ground, even on very simple scenes... I have tried loading them directly into vram, same result. I have a very fast system (3.2Ghz P4,1024MB Dual Channel DDR RAM, ATI 9800XT Pro 256MB Video card) so I don't understand this, am I doing something wrong is it a limitation of b3d?
