In general, this patchset helps more for mostly CPU limited applications than for mostly GPU limited applications. That roughly means that in general you'll see a larger difference on lower resolutions or with less demanding applications / graphics settings, and that you'll see a larger difference in cases where the GPU is relatively fast compared to the CPU. In applications that are mostly GPU limited, performance tends to depend mostly on the quality of the GL driver's GLSL compiler, or lack thereof.
Understood. Guild Wars 2 is widely acknowledged to be CPU-bound, and generally gets awful frame rates when running on wine/linux compared to the same hardware on windows. I look forward to seeing results from more GW2 players using these patches.
For anyone interested, a few players have begun to post their results in the AppDB comments: http://appdb.winehq.org/objectManager.php?sClass=version&iId=26558#Comme...
