ASUS RX580 frame rates are terrible. Need help optimizing drivers.
I turned a dell optiplex 390 to a gaming PC by adding a corsair 750W PSU, ASUS RX580, Samsung SSD and changing the processor to an i7 2600k. It is hooked up to a sanyo TV via DP -> HMDI cable from best buy.
I really only play rocket league and some older single player games. RL runs OK but there are still random frame drops that can be frustrating at times.
I recently purchased Alan Wake on steam and was baffled that I'm only getting 20-35 fps on high settings. This has me thinking that something is not set right in my drivers. I've tried multiple times running DDU (proper way in safe mode and reinstalling drivers) and setting the power limit to 50% in adrenaline (which actually did fix the even worse frame rate I was getting in rocket league before).
Any ideas why this might be? I will add some screen shots from cpuz and the adrenaline SW.
