--- Comment #17 from Ed Tomlinson edt@aei.ca --- To verify the HW is okay, I installed the catalyst drivers (14.3) and am able to run the same set of tests with no corruption at about 85fps vs 30fps with corruption or 6fps without corruption.
The r7 260x is a fairly new card. That it works at all with the opensource driver stack is GREAT. As demonstrated by the fglrx drivers, there is lots of room for improvements though <GRIN>.
