Hi,
I've recently used SFML again in a long time, where I used OpenGL directly. While debugging the application with gDEBugger, I noticed that any texture related code (for which I used sf::Texture) was calling glGetError a lot. Since there is the general concept of anything glGet* being evil in OpenGL, I fear that this might impact performance. It'd be nice to be able to toggle these glGetError calls on and off, or maybe even have them enabled only when using a debug context (i.e. sf::ContextSettings::Attribute::Debug).
