Ubuntu 15.04 Brings Some Graphics Performance Improvements For Intel Haswell

As previewed yesterday, the Counter-Strike: Global Offensive performance is up a bit with Ubuntu 15.04 for this Haswell system.

For the very basic OpenArena game, the performance actually regressed a bit on Ubuntu 15.04 Vivid Vervet.

The Tesseract performance is a bit more concerning with its regression under Ubuntu 15.04 being larger, but this open-source game isn't too popular for Linux gamers.
