Installing the graphics card driver for AMD REDEON R5 reduces my PC speed unnaturally. The driver was there from the beginning. My games Lag and for the record the PC is only 4 days old. processor is AMD A8 with REDEON R5 2.2GHz speed. The moment I uninstall the driver my PC runs fine but I am unable to play high end games. Help me here because I don't want to look like a fool who trusted and bought an AMD in an area dominated by Intel.
