Does anyone know if there are any particular problems with slowdown when you develop games with the SDL/OpenGL combination compared to just using Windows code with OpenGL? How bad is it if so? Just wanted to be sure before continuing development using the two. ^^
There is no reason you should experience any slow down with the SDL+OpenGL combination after initializing both properly.
It also works good with GLEW. Just call glewInit() and then you can access OpenGL extensions without using SDL API.
the source code for SDL is included with the download so u can see what it does, theres no inherit slowdown associated with SDL, if u can show a less than optimal main loop method with SDL, im sure the SDL maintainers (+ me) would be interested
