I have 2 Radeon 7970 in crossfire mode.
Until driver 16.1 I had no problems with sleep mode. Starting from 16.3 if I put my computer to sleep and then wake it up, the cards are not being raised from sleep.
The rest of the computer is waking up but I got black screen and monitor stays still in sleep mode. The only way to solve the case is to reset the computer.
On the driver 16.1 there is absolutely no such problem. On previous versions also.
Please fix this. AMD really sucks with drivers. Guys, you ruin each driver. The next ones are worse than the old ones.
