Thanks for the feedback
It would be interesting to have more detailed information about the game you used for these benchmarks. Usually, SFML doesn't perform that well compared to other libraries :lol: (unless you already use SFML 2 beta).
I don't understand how SFML could unleash the raw power from my video card while the other libraries I tested couldn't.
Simple: other libraries are old and not based on hardware acceleration at all, while SFML uses OpenGL under the hood to provide maximum performances.
But as far as I know, both Allegro and SDL (and thus PyGame) are working on that, and should provide hardware accelerated rendering in their next version. It would be interesting to benchmark these versions.
