Ok, so inspired by a recent thread I decided to make an FRAPS-like application that can overlay info like FPS over any OpenGL game. It's done, and I though I share. You can find it here:http://www.angelfire.com/games5/mikeman/A_GL_CATCHER.zip All you have to do is run gl_catcher.exe and it will be attached to any OpenGL app. When you don't want that anymore, just close it. It displays the fps, the resolution and the renderer. Source is included, so you can edit the DrawOverlay() and MySwapBuffers() functions to define your own behaviour(I suppose it wouldn't be too hard with a few additions to capture screenshots). I've tested it with several games(including Q2 and Doom3), so if you encounter any problems let me know.

That is pretty damn cool! One bug I found with it though - I tried it out on a vb.net level editor tool I'm making using CsGL (as a control) & it worked fine, however when I closed the catcher down with the app still running it completely killed the contents of the csgl control as well (draws a white box with a red cross in it) & crashed the program.

Did you write it? I'd be interested in the licence for this as well. I'm checking the source in a minute to see about screencaps & video capture possibilities.

DrewGreen, thanks for noting the bug, fixed it and uploaded it again. The source is free, you can do whatever you want with it. As for the FPS drop, I've only experienced a couple of frames lost in all the games I've tried it, FRAPS loose more from what I've seen.

that was quick :D many thanks for this
