Just ran another test. Downloaded FSUIPC 3.07 and set up the test flight again. And, the stutters were back. Definitely the stutters are caused by FSUIPC. I think Pete will get that straight pretty soon. Meanwhile, I'll be flying with only the default FS weather and ATC. Not too bad, though. It's a whole lot better now! :D

I have had the same problem. I get the stutters with FSUIPC installed.I can't use ActiveSky without MAJOR stutters.I am also a Radar Contact user.I have the registered version of FSUIPC and I will be glad when this gets worked out since FSUIPC is so vital to other add-ons.For now, I have removed the FSUIPC DLL, and no stutters.Scott

Does anybody know if there is a difference in the stutters between the registered and unregistered versions? I was thinking maybe stutters are a result of the extras from the registered version...

I have the unregistered version and I am stuttering.

I don't think it matters.I am getting stuttering with the registered version too.Scott

"I don't think it matters."I agree, Scott. I got the stutters with an unregistered version.

I have been using FSUIPC 3.07 and AdvDisp 2.122 on my system running under the clean boot method without any problems. I use the latest build of Radar Contact without any problems either. My frame rates, locked at 40 fps, are always greater than 35 fps.Try the clean boot method -- I am becoming a disciple. Microsoft Knowledge Base 310353.

Well, that's a really good solution if I was using XP. Unfortunately, I'm using Win 98Se... However, I do a clean boot as described. I only have 4 processes loaded up on boot and I disable two of them before I even start up FS9. I only have Systray and Explorer running. Still, if I have FSUIPC in my Modules folder, I get stutters. If I remove it completely and fly with FS9's ATC & downloaded weather, I do not get stutters. Plain and simple to me: FSUIPC is causing the stutters in my machine. Your mileage may vary.

Try to reset FSUIPC to default settings and do not run any external software (FSmeteo, ActiveSky, Radar Contact, etc) and try again.If you still have stutters, post a message in Peter Dowson forum, he is very helpful:http://www.forums.simflight.com/viewforum.php?f=54Ulisses

Thanks, I'll try that. I've been looking for his forum and couldn't find it.

"Try to reset FSUIPC to default settings and do not run any external software (FSmeteo, ActiveSky, Radar Contact, etc) and try again."Not much to reset on an unregistered version. And the sim stutters with the .dll in the modules folder, whether external programs are running or not.

"Not much to set on the unregistered version"You might not *THINK* so, but clicking the "normal defaults" and "minimum weather defaults" buttons effects a large number of changes that the unregistered user doesn't have direct control over. I'd start with minimum defaults and see if anything changes for you. If not, try normal defaults. A description of what is set upon clicking these buttons should be in the readme.sg

Sorry, Gridley, I should have been clearer in my statement. I was thinking about the numerous settings within a registered version.I have indeed tried the normal defaults and minimum weather defaults in the unregistered version. No joy.I'm not here to bash FSUIPC... I WANT it in my sim. But I get the above noted stutters with it aboard, no matter what I try, so I've removed it for the time being. Fortunately for me, I have no requirement for it at this time.Regards,

have you tried deleting the fsuipc.ini file, and let it recreate itself?

jd, I did that when I updated my FSUIPC to v3.07. Deleted all of the 3.06 stuff from my Modules directory then installed v3.7. Started up FS and still had the stutters with FSUIPC in there. Makes it really tough to run Radar Contact much less FSMeteo. ;( There has to be something in FSUIPC causing these stutters. There not really too bad, maybe 1-2 second pauses, but it detracts from the otherwise great experience. You can only notice it if you have the Average Frame Rate showing. It shows up in the V% which is constantly changing. The stutters causes the V% to stop momentarily. Otherwise, you might not even notice the stop because the sound keeps running as does the mouse...... :-hmmmSteve
