I downloaded your demo and put it in the editor, I went to Gethal Labyrinth I, changed party limit to 8, added actors 1~8 and made them level 99, made an event that gave states 4~6, 37~43, 12~16, 20,24,27,30 and changed blind to +hit rate and all to no removal timing. the only lag I had was selecting a target which lowered frames down to 4 from doing nothing, around 30 from instant accepting, I disabled MOG_CursorBorder,MenuBorder and YEP_BattleSelectCursor, helped slightly, disabling X_SelectionControl removed it entirely, but I also use that with no lag so not sure why and I use slightly more plugins, attacking wise it was slightly less small frame drops, then I added all those states to actor global in passivestates and the lag actually decreased and the SelectionControl issue disappeared, as long as the other 3 were disabled but still lagged badly with those 3 on. So that was 256 states on just actors with the ones you already had set, more than my tests and I saw no real lag, hardware wise I only have a 2500k overclocked. If you are lagging still maybe check newly added plugins since demo or specific custom states.
