I have tested wine-2.21 on both T430 and X230. Performance increase is very very noticeable. We are able to play PvP without the game freezing for a few seconds and we do not get average of 20fps anymore. My T430 can sit around 40-50fps (small fights) on minimal settings with native sampling at 1920x1080. Interestingly, lowering the resolution does not increase performance at all. Should I build and test the new version as well?
