hey guys, i have been working on a map for some months now but recently i have encountered a problem; the game begins to lag badly after about 45 minutes. this lag is not related to connection speed, and i'm pretty sure it's caused by the CPU having too many operations to handle. do any of you know what things might cause something like this? i'm currently going through my triggers and doing whatever i can to reduce lag, but if there is something that REALLY causes lag i'd be interested to know what it is. thanks.
