A few things to consider: > textureData = pygame.image.tostring(textureSurface, "RGBA", 1) * You're creating an extra copy of the texture data here. To avoid that, you could use surfarray to create a surface backed by a numpy array, do your drawing into that, and then pass the numpy array directly to glTexImage2D. > texture = glGenTextures(1) > glBindTexture(GL_TEXTURE_2D, texture) > glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST) > glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST) * You're creating a new OpenGL texture for each frame and then discarding it. Try making these calls just once at the beginning and re-using the texture. * You're using a non-power-of-2 texture size. Not all OpenGL implementations support that; yours seemingly does, but it might be less efficient than a power-of-2 size. You could try allocating the next larger power-of-2 size and updating the part that you use with glTexSubImage2D(). -- Greg
