Hello, currently in my engine I use the normal wglChoosePixelFormat to find a pfd. What is the diferrence with the arb_pixel_format selector?

wglChoosePixelformat uses an fixed struct and isnt going to change that in a while… So if you need to ask for newer buffer configurations (PFuffers, FSAA-modes, and a few more) you need to use the new one.

Whats a PBuffer? Sorry for my ignorance on that

A pbuffer is an off screen hw accelerated pixel buffer.

And what could we use it for?
