hi %subj% is too damn high. Of course there is checkbox *run in background* unmarked, still game eats as much as it does when playing. why? As far as i can understand. all the load (when playing) comes from resource pieces. I first thought that were my conveyors or big techs - tried to optimize them, make smaller etc - but not, after destroying everything and having only one resource holding platform with 10 4x4 buckets nearly fully stacked the game runs slow as hell.
