I have a 5800X and 6800XT and get ~50FPS in "Tangled Shore" after switching from a Nvidia 1080. I checked all limits using HWINFO v6.40 and it's not the GPU or CPU reaching it's limits, GPU utilized ~50% and most used CPU core is ~50% as well when this is happening. The clocks on the card are around 1500 when this is is happening. Forcing the clocks higher to 1900 (base clock) minimum does not help the FPS/issue at all.
