I want share here my bitter experience with the new driver.
I bought an Asus R9 270X and used it for years without any problem.
Last week wednesday i upgraded my driver to Radeon Crimson ReLive Edition 17.4.2.
I used a 10% performance boost in the Built-In overdrive section.
Soon as i started playing Stellaris, the Radeon Wattman exe crashed, then i checked the overdrive settings, that reseted to the default values, so i dont bother with that and contuined playing the game. A few minutes later colored horizontal stripes appears on the monitor, flickered few times then the pc restarted itself.
From that moment i cant start the windows with the card, i deleted the drivers and take out the card so now i can use only my integrated vga.
