Is this happening to anyone else? Game pausing at random moments

[marscaleb]

I have a very annoying problem with my project, and I was hoping to find someone who has either dealt with it or is dealing with it so we can compare notes.

At (as far as I can tell) random moments the game will just hold up for a moment. The player pawn just freezes (possibly the whole game, hard to tell) for a brief moment. It looks like I just miss a small handful of frames and then the game resumes. It looks almost like the game were loading some content and so the game just stuttered, but there is nothing being called to load.
It doesn't act like the game paused and then picked up where it left off though; it acts like the game just kept going but I couldn't see what was going on.

What makes this worse is that this unforeseeable event tends to compound some of my game mechanics. For example if I am in the air some of my physics calculations can be cut and I get more height than I should or hit the ground harder than I should. Or my moving forward compounds things I when the game resumes and I'll hit some wall and the game decides to move me off to the side (and since I working with a side-scroller that puts me out of phase with the whole world.)

Try as I might, I can find no reasonable occurance for this to happen. It seems common to my moving, as that is when this glitch is most devastating, but I wouldn't really see any difference if I'm not moving. Walking or jumping or landing or bumping, specific areas and specific geometry, at particular times or not, I can't find any reasonable cause.

I can't reproduce that here.

Do you have any custom movement code?

um, if im think correctly it might be your ram
ive had this happen to me in other games b4 this pc, it was the ram acting up,
i would wait for new version of udk and see if it continues.
if you are using xp i recommend getting eBoosta
or windows 7 " google windows 7 flash drive as ram"
on the slight chance it might be your processor been off time.
update drivers (all) and udk and see what that does.
good luck

Buddhist Punk:
Yeah my computer is a bit on the lower end, but it still represents the kind of computer I want my game to run on, so I kinda hope it is not a memory issue.

ankangronto:
Yes; I had to rebuild all of my movement code because the pre-existing code is not suitable for my needs. I keep wondering if this is caused by some problem with my movement code, but I can see no reason why this would happen, or rather, why it would be so intermittent and random. The movement code is pretty simple; if there is a problem it should be manifested pretty regularly.

Try running your game using the profiler. It may pinpoint any functions that are abusing the system.
