Is there a framebuffer objectin sfml?If not, can someone show me how to remove tearing from an application? Thanks.

The equivalent of FBO in SFML (2, not 1.6) is the sf::RenderTexture class.

But how would it remove tearing?

Doesn't SFML use page flipping(what I assume you want to implement with frame buffers) internally anyway? If you're still getting tearing then you need to enable Vertical Sync.

I dunno, I thought that was what framebuffers were for. What is the renderTexture used for?

I just found out that what Im looking for is called a doublebuffer. Sorry. Is there a doublebuffer in SFML?

Yes, SFML always uses a double-buffer.

ok thanks. Another question: does changing the window's framelimit change how many times the main loop is gone through, or just how many times its rendered?

It pauses the whole application (the pause is hidden in the Display function), so it changes how many times the main loop is gone through.
