I have been programming in OpenGL, and have noticed how my fps drop dramatically whenever I begin to texture map using BMP’s (the RGB ones) on win9x O/S. I know I can use smaller BMPs to bring up the FPS some, and or tile my textures, but maybe BMPs are not the way to go. I know most professional programs that I run don’t show the same slow down that I am seeing. Are they texturing with something else besides BMPs? They must be.
Hi, the type of image format has nothing to do with it. .bmps are just as good for texturing as anything, only they dont support an alpha channel. Are you making use of texture objects?
You could try to use compresed textures with the extensions of OpenGL.
