Hi there! I'm so sorry to hear about the slow-down. Super large games can cause lag, a good way to test that is by creating a new blank game (or standard module) and trying out a few basic tasks to see if you still run into problems. I also recommend checking to make sure that Hardware Acceleration is enabled. (I have information on how to check that here .) While partial cause could also be an aging computer system, the team has been hard at work with Project Jumpgate. Jumpgate is designed to bring performance improvements to all kinds of systems, so that will definitely help you out there.
