Hi all,Notice distinct pauses or stutters <2 to 3 secs> whenever using FS9 replay - daytime or nightime and zoomed close or far and weather active or turned off - in normal 2d cockpit mode I am getting average of 20fps with pmdg 737 - which seems to present a fairly smooth environment while flying- thats even with most FS9 settings maxed out I have tried the recommended FS9 config file settings - but no change to the replay pauses. My hardware is reasonable - P4 3GHz / 1Gb Ram / ATI 9600 256 video card.Anyone got any ideas ?Use anti virus but have tried with it disabled and no difference.Am at a loss to understand thisCheers RogerEGPF

I've never seen 2-3 second pauses during a replay, although playback of recorded demos has never worked well since FS98. But replays are pretty smooth for me--and my system is far inferior to yours. I believe the replay buffer is played from RAM, so there may be some odd issue fetching that from RAM which is causing your pauses. I wish I could suggest more, but it's not a very common topic here so I haven't seen much discussions of these types of issues.-John

Thanks JohnGot me stumped as well - as during live flight it is very smooth - no noticeable pauses at all, wondering if it could be a virus issue or some kind of memory hogging program within XP.Not a major issue for flying of course but I am curious to understand what may be going on here.Have had a problem with XP running programs not showing on the taskbar, ie I can only access them using alt tab once they have been minimised so a re-install of xp might be required, but will wait and see if anyone else has any suggestions.Cheers RogerEGPF - Scotland

My replays are fairly smooth....But my videos....:(Not too good....I never used to have trouble playing videos on past versions, but playing a vid in 2004 is stutterville...When I do just instant replays, I don't get any bad stutters to speak of...I'm running a P4 2.4.Not real fast , but not real slow...About average thesedays I suppose...MK

I've noticed pauses during replay. One odd artifact is that if my aircraft is streaming smoke (as during an acrobatic performace), if it pauses during the replay, the smoke will continue to issue during the pause, resulting in a little puffy cloud when the replay resumes.-- Walt

i added RAM my computer (up to RAM 2gb) it partly solved the problem. the other thinguncheck "Real World Weather" or check to "User-defined Weather" it mostly solve the problem that yours.

I think in earlier versions before FS9 you could choose the resolution of the recording/playback. In FS9 and FSX the record routine doesn't "capture" frames or even a block of frames. It takes a snapshot of your aircraft position and attitude at very coarse intervals, then interpolates the missing data and estimates the movements in between known positions. It therefore misses a lot of detail about how you flew the aircraft. That's why on playback you get odd movements, a tendency towards jerky behaviour, and the sound is mashed too because it even interpolates rpm and power between its data capture points.Of course this is not video recording. It is position and attitude recording that is internal to the FS flight software and not a capture of visual frames.Unless someone comes up with a workaround to make the position capture much higher resolution, playbacks are always going to be flakey.Rob Young

I had the same problem with the FSX replay function - a ridiculous jumpy replay.Solved the problem by making sure I was in Locked Spot View prior to flying. The replays now are almost as smooth as they were in FS2004.Hope that helps.
