Bug Description
On an AMD R7 260X with the radeon open source driver, glmark2 produced a result about 8x slower (I think it was failing to use hw acceleration) than the fglrx driver, which supported the hw acceleration properly.
1. Mint 17
2. Run glmark2 with the radeon driver and either compare the result to what it should be, or also run it with the fglrx driver.
3. It was about 8x slower, ie the score was about 8x less.
4. It should have run with similar speed.
5. Always.
NOTE: 'amdcccle' (with changes settings for fglrx) has a 'Tear free' option which is very useful, but will lock glmark2 to the display frame rate, causing a score that is far too low (and equal to the display frame rate).
