CPU drop affects GS performance

viking

I was experiencing a huge drop in frame rate every 100 seconds when I was previewing my game in the Creator and I had no idea what was going on! It drops from a steady 60 FPS to 40FPS and then slowly builds up again to 60FPS. It was strange, because I didn't see the same drop in frames running AdHoc on my iPad. Then I did an Activity Monitor test on my MacBook Pro while running GS and previewing my game. I found something super-weird. Every 100 seconds or so, GS CPU usage % drops from an average of 40% down to 29% corresponding perfectly with the drop in FPS in the game and then slowly goes back to 40%. No other application shows up as stealing CPU power from GS, so I have no idea of what's going on.

It is annoying because my game is unplayable at 40FPS when I am testing it. Anyone have an idea of what this could be? Anyone else experiencing the same problem?

You have some spot in your code that is causing the issue. Try turning off actors until you find the code that is causing the issue. If it is a GS issue at least you can narrow it down for them. Or there may be a mistake in that code or a bloating issue et..

I guess @Lost_Oasis_Games that this is the most plausible explanation. But then why does the game run perfectly on my iPad?

I will try to comment out one actor at a time in the scene and see if I can find the culprit.
