I have a laptop with builtin Intel graphics and dedicated AMD graphics. I recently downloaded Raedon software and now the games are working at 1-7 fps when compared to previous 35-40 fps.
I have also tried uninstalling the software, but has not uninstalled even after more than 12 hours.
It sounds to me as if your laptop is using the Intel graphics chip rather than the AMD card. Try reinstalling the AMD drivers and then disabling the Intel graphics chip in the Windows device manager.
