GLXOSD is an extensible on-screen display (OSD)/overlay for OpenGL applications running on Linux with X11 which aims to provide similar functionality to MSI Afterburner/RivaTuner OSD. It can show FPS, frame timings, temperatures and more in OpenGL games and applications. It can also be used to benchmark games, much like voglperf.
This is not really a "pull request" in that I expect you to pull it - I'm not sure if this feature is useful enough to warrant inclusion. I figured posting here anyway in case other people are interested.
I added the keybinding because of a frustrating bug in Metro 2033: Redux; for some reason the game would toggle VSync off whenever I alt-tab to the desktop, with no way to turn VSync back on through the ingame UI.
