Re: [pygame] Speed up image.tostring with OpenGL ?
The only other way I know how to make OpenGL textures is with NumPy, using the GL_FLOAT token. This may be better for your purposes--although the way I see it, converting a surface to a texture is going to involve a conversion no matter which way you do it. Note that it's much faster to update a texture rather than create a new one. If at all possible, this may be your best opinion to improve speed.
