Pretty poor performance from my new 6800, just replaced a 1080Ti. 1080Ti used to get solid 144fps pretty much everywhere before BL, then went down to 80-144 in BL. Got the RX6800 and first load in to game was getting 8fps, which didn't change depending on resolution or graphic quality settings. GPU was being utilised less than 50%, so little the temp was less than 60c and fans didn't even spin up. Eventually it cleared and ran about 60fps. Did a totally fresh install of Windows and re-downloaded D2 fresh, and it's a little better, but still not good enough that a new AMD GPU is running half as well as a nearly 4 year old 1080Ti that's less than half the speed.
