I've tried everything and after years of successful flight simming online I have come across a problem that I can't find an answer to anywhere. I fly with FS9 on VATSIM with SB3 or FSINN and for some reason the frames go down to 1 and it starts to lock up. Processor just shows that FS9.exe is at 100% but as soon as I disconnect from SB or FSINN frames and CPU go back to normal. Does anybody have any suggestions as I've formatted my computer and am running the same machine that was working fine around the first of November. Any help is appreciated.Thanks,Corey

100% CPU use is normal for FS.SB3 will cause a framerate hit. i only notice when other aircraft are near. keep you mouse clear of the SB3 SQ control and text window (except a quick pass when needed for input). if your mouse is on the SB 'windows' FS will react with a slideshow.i don't use FSInn so cannot comment on that program.(you may wish to post your system specs.; this will allow others to comment with more detail.)--
