I have a R9 270x and i'm using windows 7 64 bit .
Recently i started to notice that after playing a game or any other graphically demanding program, My GPU usage will not go down after closing that program and will stay at about 90%-99%, even after a couple of hours
Only after restarting the computer the usage will go back to 0% when idle.
I ran a scan using malwarebytes and found nothing, and it looks like there is no process that is using the GPU.
I noticed it after i updated catalyst to 14.4 but i went back to 13.12 and it hadn't solved the problem.
Any idea what can cause this issue? Here is a couple of screenshots of the problem: http://imgur.com/a/MTqxG
Thanks in advance.
