What is the fastest way to draw a texture mapped sphere? I used gluSphere(quadratic,1.3f,32,32) and it works nice on TNT2 16MB (60FPS) but when I try it on a 4MB rage, the frame rate is something like 8FPS (its 20FPS if the distance between camera and sphere is great enough) ?! the texture is 512x256, for the sphere I cannot use less than 32x32 (not circular enough), display is 640x480x16, so I am wondering is there a better way to draw a texture mapped sphere? maybe use bezier curves to lessen the amount of vertices? Any ideas?
Thanks
