I have R9 290X and R9 290 running in crossfire mode.
Have only been playing dota 2 (no crossfire) since crimson update, and I just noticed that fullscreen games using crossfire will freeze and stop working when I have it enabled. The screen completely freezes and I can't even ctrl+alt+del. I have to restart my computer. There is no such problem when the crossfire option is off.
I have checked both graphics cards in single gpu mode and both are working, so it must be the software. I have tried clean uninstall+reinstall and it doesn't work. Can anyone help me?
