Hi! I've been puzzled for a while over low fps when my system isn't taxed at all, and finally found a solution, at least for my case. your mileage may very.
Everyone knows AMD has issues with openGL, but the miserable 10fps with all my gpu power free was perplexing. After much time and research, it turns out NEWER drivers DO NOT SUPPORT opengl hardware acceleration AT ALL! dropping it in favor of vulkan.
After uninstalling my drivers and searching high and low for the older catalyst drivers i'm now running at 60fps with catalyst 15.7.1! it's still a little buggy as AMD sucks at openGL but it's truly playable for the first time since my purchase.
If there are not older drivers for your card, there are two more options I've not attempted. The first is to find a openGL over Vulkan wrapper(something still highly WIP) and the second is to switch to Linux and get the RadeonSI driver form Mesa. The RadeonSI driver blows the official drivers away, in some cases giving a 300% improvement. it's just a shame that that performance comes at the cost of the windows OS.
