I have a Sapphire 5700 XT nitro+
Drivers are more or less okay regarding black screens, crashes, and that kind of stuff. Some games crash on me regularly; for instance, Battlefield 5 always crashes right after finishing the war story. The game saves my progress, but then it just crashes.
Some games run "weirdly." For example, Call of Duty: Infinite Warfare runs at 90+ fps for me, but it isn't smooth. There is constant stuttering, and FreeSync doesn't help at all.
But there are some things I don't quite understand. I am fairly sure you would get a better framerate at 1080p resolution with an RTX 2070 than with the 5700 XT. For some reason, lowering the resolution to get better performance doesn't work here at all. This means those tricks like 80% resolution scale plus image sharpening don't make sense. Simply put, you lower the resolution and the games use fewer resources, so you end up with the same or even lower fps than at a higher resolution.
Here is a screenshot benchmark for Far Cry New Dawn, for example. 1280x720 vs 2560x1440

Maybe the problem is my CPU (Ryzen 5 2600X), I really don't know. But if it is weird, it is weird.
