What's up, RMers?

As long as the maps are on the 250x250 range, I get no issues. Bigger than that though, and the game becomes a stuttering slideshow.

Hold up.  PUT ON THE BREAKS.

You're not using an anti-lag system to control/handle the large number of events and graphics in your maps?  Without such, the system will attempt to update 'all' events in your map, and all graphics in every 'cycle'.  With an anti-lag, it updates the graphics within the designated window which only the player sees.

The MAP sections within the Forum Script Listings thread should point you to a couple if you're in need.
