Severe stuttering and lag since upgrade to Sapphire 5700 XT Pulse
Title. The issue is at its most severe in Crucible, where I will black screen and start the match at anywhere from 20 to as low as 4 FPS. My FPS improves as the game goes on, slowly, but if more than 2 enemies are on screen I will go from 90-100 down to 40-50 FPS.

I KNOW its my graphics card because I just upgraded from an EVGA GTX 1070 ACX Black Edition that was superclocked and was easily getting 80-100 frames with no stutters. I upgraded from a 2600 to a 3600 earlier this month and also had zero issues. The GPU is completely stock, haven't done any clocking adjustments.
I had the same issue when moving from Nvidia 1060 to AMD 5700 and ended up having to do a reinstall of Windows. Make sure you have the latest motherboard drivers as well as the latest AMD GPU drivers. I did nothing special other than reinstalling everything fresh. It sucks but I wouldn't waste your time trying to mess around with settings and all that nonsense, you have to reinstall windows and then it runs like a dream.
