Nah. Nothing weird or wrong about my setup.

Everything worked fine with my Nvidia 660ti. When I switched to an RX 580, I had issues with refresh rates and Freesync (that I can remember, it's been awhile and I don't care to keep all this recorded.) Some versions of drivers would fix issues but cause others. Some versions required certain configurations to fix issues but cause others. It was a mess.

Switched back to the 660ti, no issues. Bought a used 1070, no issues.

Haven't gone back to AMD since that horrendous experience, but maybe they've improved.

I think it's sad how few people here are willing to acknowledge that AMD's drivers may not have been adequate for most users even if they worked for them. I bought AMD listening to ya'll, and was horribly disappointed.

I guess that's part of why theory is no substitute for experience.
