Hi,I have a strange & persisting issue with Wilco's 737 PIC. While FS2004 (or FS9 - whatever) runs very smoothly on my Vista-32 machine, when using the 737 PIC the framerates seem to cycle: for example, setting the max frame rate at 28 fps, the actual fps alternates between 17 and 28. Setting the max frame at 17, fps alternates between 8 and 17 etc. This causes a stuttering sensation in the outside views which is annoying at best...All 'standard' aircraft run very smooth, fps up to 60 even. I have tinkered with all kinds of settings, both in FS9 and the 737 PIC set up - does anyone else experience this problem and know how to fix it??

All 'standard' aircraft run very smooth, fps up to 60 even.

default FS aircraft have no detailed system simulation ... and as a result have little demand on a computer's CPU.

I have tinkered with ... and the 737 PIC set up

have you adjusted different gauge refresh rates in the 737's config utility?old support forum -http://iemit.com/forumopen for searching, not open to new posts'new' support forum -http://forum.iemit.comregistration required--

Yep - the problem is not with low fps itself, but the cycling between different rates that only appears using the 737 PIC, not with any other (generic and add-on) aircraft.I have searched every forum I could find - but to no avail yet...Thanks for posting.Jaap
