Intel Graphics Performance: Clear Linux vs. Xubuntu 16.04 LTS vs. Fedora 23 Xfce
Xonotic with lower image quality settings saw Clear Linux and Fedora 23 Xfce both much faster than Xubuntu 16.04 LTS, even when Xubuntu was running with the latest Git components for its Intel open-source driver stack.
With the increased intensity of Xonotic's in-game settings, Fedora 23 and Clear Linux continued to run neck-and-neck while being much more competitive than Xubuntu 16.04 LTS.
For those wondering, no Steam Linux game tests were done since Clear Linux doesn't have all the necessary dependencies in place for handling Steam. There's also been upstream regressions with some Steam Linux games for benchmarking.
