Since yesterday my graphics card is underperforming. I started Just Cause 2, and my highest framerate was 20fps. But 3 days ago i had played it on 80 fps... So i tryed other games, and also there the framerates are very, very low. I searched on the forums and google, but all posible solutions didn't work. I have restore my system, reinstall Windows, all drivers and still graphic performance is very bad. 

So i downloaded MSI Afterburner and TechPowerUp GPU-Z to see if the problem is something with my clock speeds, and yes it is.

Screenshot 

My GPU clock is now 100 Mhz, and also Default clock is set at 100 Mhz, before this problem it was 725 Mhz.... 

I din't do anything related to overclocking so that can't be the problem. Now, i have tryed to overclock it back to it default fabric speed, but it has no results....

To solve the problem, I think i have to get the clock speed back to 725, maybe this is not the problem. I'm don't know very much about overclocking and all the things that come with it.

Some information about my system:

A quick google resulted that many laptop owners with amd gpu's have that issue. Try disabling/re-enabling PowerPlay (if your gpu supports this feature). Also make sure your power settings are set to 'high performance' and if still nothing changes force your original clocks using amd overdrive or any other overclocking software (like msi afterburner) to frequencies which should be 725Mhz core and 800Mhz memory and the issue may fix itself.

I did disable and re-enable PowerPlay, no result. My power settings are always on high performance, I also checked the advance options tab in the settings. When i try to force my original clock speeds, TechPowerUp GPU-Z show me that the clock speeds are back to original. But when I play a game, the fps is still <20...

You might try these drivers. Uninstall the old ones and run Driver Fusion first

Wow, that is the first drivers that's not from HP and don't give any errors during install. After install and reboot, my GPU-Z displays my clock speed as 725 Mhz, but after 3 seconds it is 100 Mhz again. I think my videocard is downclocking itself, (if thats possible).
