Yeah, well the whole idea was to see if I could gain some more performance by using the latest DXVK version.
World of Warcraft is working fine for the most part (about 80-100fps) stable in dungeons and about 60fps in battlegrounds. However Hearthstone is lagging like crazy, (about 20-30 fps) which is unacceptable for me even for a card game. But you are right, if everything else fails we can always fall back to 0.54.
