The memory isn't suddenly maxed out and neither the step or draw loops are going over their allotted time. Still about 16ms between frames and game seems to be running as normal based on sounds and debug messages. The only major change from previous version is adding of large background images for a new level. The texture page size was already increased to 4096 which is larger than any of the new images (just checked). There IS some code used for pausing which takes a screenshot and displays it (for bringing up menu) but this still happens when it was commented out. Has anyone seen anything like this?
