I compared English US with my pack and couldn't see any big difference in performance.ĭramatically slowing down sounds disproportionate. My system is pretty old too and the performance is good. My Antivirus program doesn't produce any delay. Then you should also moan about any skin, which uses the same system. Publishing packs as one self installing file is good too. Wlz system is the best system I saw, it makes it easy for translators to create and test their own language files.
