First up is the basic OpenArena open-source game test...

Radeon R7 Ubuntu Gallium3D Catalyst Benchmarks

OpenArena showed some modest improvements for the open-source Linux graphics driver stack when using Linux 3.18 and Mesa 10.5-devel over the stock (X)Ubuntu 14.10 setup. However, the Catalyst binary driver still came in as a bit faster.

The Catalyst driver had the lowest average frame latency time while the Linux 3.18 + Mesa 10.5-devel configuration had the highest peak frame latency -- the clean Ubuntu 14.10 install came in with the lowest peak.

The open-source Tesseract game on the A10-7800 APU seems to do a bit better on the open-source AMD Gallium3D driver than with Catalyst fglrx 14.20.

The more demanding Unigine Sanctuary test shows the open-source AMD Linux driver code moving in the right direction but that Catalyst is still faster with the more demanding OpenGL workloads on Linux.
