I have an AMD Thunderbird 900MHz, ATI Rage Fury 128 AGP (32Mb), and 96Mb PC100 RAM. When I texture some triangles in OpenGL (using Nehe’s code), my framerate drops horrifically. I have a theory that maybe it’s not being sent to video memory… any ideas on this? Why is it so slow?
I think you gotta use char *str = (char *)glGetString( GL_VENDOR ) at least I have to for c++. But performance does tank when you use textures, especially if you use large textures. If you have blending etc on it’ll tank it even more.
