I am using FRAPS with FSX as I have always done, and since installing SP1 have noticed a big drop in performance. This is weird because while FSX nows runs at least 50% faster, FRAPS is causing jerking and stuttering in a way it never did prior to SP1.

I record half size display, dont record sound and typically at 25FPS. I wondered who else is using FRAPS and may have noticed a similar performance issue.

I use fraps but havnt installed SP1 yet....maybe an email to the Fraps people could shed some light?

I have no basis for comparison, as I didn't use fraps pre SP1, but it doesn't make any performance difference now. Especially seeing as I get a real time print out on my keyboard LCD monitor
When recording movies it drops to 20 frames or so, but I suppose that's normal.

hmmm yeah....bit of the jitters it seems. Jerky etc

Yeah, may have to do that, it seems quite strange.

What is FRAPS??

A recording program. You can film a part in fsx then use FRAPS to chose what to have in the final.

Close, FRAPS records the footage from any game or your desktop etc, then you can use video editing software to put it together etc. The Free version records 30 seconds and puts a watermark at the top, but you can record as many 30 second slots you want.

Do you have a dual core machine? It's possible the new way of scheduling is affecting Fraps (which presumably runs on core 1). There's a tweak on Phil Taylor's blog that might help:


There is a tweak to control scheduling of threads on cores.



It is not recommended to change these settings unless you have a performance reduction and/or maxed out CPU loads in the PerfMonitor. The tweak is

Edit:Fixed a typo here
[JOBSCHEDULER]
AffinityMask=n
where
n num of cores scheduled
1 = 1 core 0001
3 = 2 cores 0011
7 = 3 cores 0111
15= 4 cores 1111

Closer than i thought i would be considering i don't have it

Well back in the day when i started making movies on 2002&2004 everyone was having these problems ,i tryed and tryed until i came up with slowing capture to half if not 1/4 speed when recording ,
this was due to computer performance full stop ,i got a new puter and was finally able to use it at full capture speed with sound
ive always captured at full screen at 25flp or i did it at 29.9flps ,
my only answer to your problem is that you are no where close to the specs needed now to run fsx and fraps together ,as with your sp1 upgrade it is putting more presure on those hardware and software /memory,space for the sim and not leaving enough for the fraps addon.
the only thing now i can imagine is slowlying your sim speed down to capture until you or we all have high spec puters to run fsx properly
also check out if it will play back ok in media player as others like winamp and simular just dont like playing back raw footage from fraps ,i say this because ive recorded and got jars in the sim but when played back in mplayer it was sweet
zol

When recording movies it drops to 20 frames or so, but I suppose that's normal.

this is not normal at all maybe 10flp at most over big citys of eye candy but most of the time it should always capture at 25flp if your sim is held at 25
and the frames are set in fraps at 25 anymore than that you mite aswell well make a time lapse movie that needs 50 double real time capture
anyway hope this helps abit

I have mine locked at 35fps and it dropped to 20/25 during recording. Recording at 1/2 size (i.e. 640x512) and 30fps (for youtube).
not too concerned with a drop to 25, but certainly useless if it falls below 20fps.
I've tried doing the half speed recording too, but of course it puts those red labels on the screen and it changes the sound pitch (though I haven't tried setting the software to keep the pitch static)
