View Full Version : texturing speed

how much of a difference should i be seeing in terms of performance if i texture a quad using a 256x256 image vs a 512x512 image? i.e. what would be a fast way of texturing a square the size of the screen (in full screen mode) using an image of that same size? should the texture be cut up into tiles and then mapped? i hope i'm making sense...

If you want to cover the full screen with a textured quad, you should use one quad, with one texture. It's faster than using multiple objects, especially because you want to use a texture image with given size. Even when your quad is tiled all data must be transferred to the video memory. So better using it in one piece.

Not all cards support large textures, the early voodoo cards can only have up to 256*256- thats why some programs split up large textures.
