Are you using WinXP? Or Win 10? You really did a great job listing your specs and describing your issue. I wish everyone did the same. However, the OS is very important in the early days of Win 10.
Anyhow, when you get this problem, do you have another window (or two) open to places like You Tube or watching Scooby Doo while you are playing a game? If so, the hardware acceleration can be disabled on each.
Is your PC power plan set to 'Performance'?
In the CCC do you have Overdrive enabled? Do you have a Power Limit setting? Is it set to the maximum...which will be probably +20 or +50?
Since this has gone on for awhile, check your system files by starting a command prompt as administrator and type sfc /scannow It doesn't take long and if corrupted files are found they are repaired.
You can install the latest DirectX (and earlier if you are playing DX9 games) updates here > Search results - Microsoft Download Center
Lastly, I would do a clean install of the drivers > Clean Install AMD Graphics Drivers
Oh, I forgot to say it, I'm using windows 7 ultimate Service Pack 1
Man, I did everything you said, and then I tried with Batman if it had worked, but not
I have Win 7
The problem occurs if I got something else open or not :T
I had my pc in perfomance, but I put it on equilibrated, and it's the same
I had overdrive enabled, and I disabled it, The power limit is in 0
I did the scan, but I don't know what it did
I installed the latest Directx aleready
And finally, I did the clean install
But nothing worked, Than you anyways, but I don't know what to do, I played Batman and the game was fine, but after a while it started lagging and stuttering, that what happens, I don't know what to do ;-;
The PC power plan should be set to performance.
Overdrive should be enabled.
Power limit should be set to max (not 0)
