And the AMDGPU Pro driver didn’t fix stuttering in Wurm Online

So it's a game problem. Assuming I was actually using the Pro driver. Going to uninstall the Pro OpenGL driver now.

I was staying at 90 FPS or more, then it got a massive drop, and stutter. Thought it was fixed, but it isn't.

Hmm, maybe limiting the FPS more, will let the FreeSync work. I have it set to 95, but it goes up to 100. So try 85. Does FreeSync work if it's off and then engages when the FPS drops? Or does it have to be on before it drops? If so, lowering the FPS limit might help. Or maybe they did something so FreeSync doesn't work.
