Unigine Valley on RadeonSI with the R9 270X was running at less than half the speed of the Catalyst Linux driver. The Catalyst Windows driver remained noticeably faster across the board. The Radeon R9 290 on the open-source driver was also in a broken state for Unigine Valley with Linux 3.17 + Mesa 10.4-devel.

For Unigine Valley at 4K, likely the most demanding OpenGL Linux benchmark at this time, the Windows configuration was 23% faster than Linux with Catalyst for the high-end Radeon R9 290.
