I have an MSI R9 280x 3GB, and I've been having all sorts of trouble getting it to work properly. My latest struggle is with the clocks in game. When I play less demanding games, such as source engine games, the clocks go down to the idle settings. This causes massive performance loss and a game that this card should easily run at over 300 fps is running at around 30-40. I don't know how to put the clock at the 3d settings manually and could really use some help, thanks!
