glxosd and voglperf now available for Fedora in COPR

For all our gaming enthusiasts, I packaged glxosd and voglperf for Fedora and you can find them in my COPR repositories: glxosd COPR and voglperf COPR.

These tools allow you to have FRAPS-like features on Linux, i.e. show an overlay in OpenGL games/apps to display current FPS, and also capture the frame times into a file and plot them to a graph later. So you can now use it with any Linux game and fine-tune its graphics settings to match your preferred performance. Or you can see when your CPU or GPU is overheating. Or you can contribute to Open Game Benchmarks. Or something else.

This is an example of the glxosd overlay in action (don’t worry, its output is configurable):

And if you want, you can later plot the performance into such pretty graphs using this awesome glxosd analyser web page:

And this is an example of the voglperf overlay (top left corner):

And a generated graph:

There are other similar tools which you can use, but I know about any that is generic and has all these features. There is of course the Steam FPS overlay, but you can only use it for Steam games, and it can’t log frame information. There’s also GALLIUM_HUD, but that’s only available for Gallium-enabled drivers (radeon, nouveau) and also can’t log frame information. These two new tools should work with any driver and can be used for any game/app.

You can find installation instructions in the linked COPR repos. I do not intend to move these packages to official Fedora repos, but if somebody is willing to get their hands dirty and work on that, great, please contact me and I’ll try to help.

Enjoy!
