I've noticed recently that when running GM games, periodically they take a brief hit to framerate and then bounce back to normal. Usually it slows about 20-30 fps for about 3 seconds and then resumes. This happens at regular intervals too, which is really weird. I only noticed it tonight on a large project I've been working on for a while, but a friend who'd been testing had mentioned an issue like this to me before several weeks/months ago. I spent some time debugging and trying to figure out which programming was the culprit, until I tried creating a new GM game with a blank room and found that the framerate was still doing the same thing.
More likely than not this is an issue that has to do with hardware, and it may even disappear when I next restart my computer. But it's still a bit disconcerting. I'm on a pretty new Lenovo Thinkpad running Windows 7, so it's not like there should be any strain there. I'm wondering if there's some sort of system setting that might be the cause? Does this problem exist for anybody but me and my friend?
EDIT: I should mention that this is specific to GM 8.1. I haven't tried this in other versions (yet?).
