Guys, due to problems with the new Squawkbox 3 and others who had luck by re-installing FS9, I bit the bullet and went ahead and re-installed.
I then added just a single aircraft, my Phoenix Simulations Software Dash 8. I've had this since FS9 first came out and few it all over without any trouble. Now, whenever I load it, every 3 seconds the sim stutters for no apparent reason. Worse, if I then switch to another aircraft, the sim STILL stutters but if I never load the plane, no stutters at all.
This is my favorite plane and it never did this before. Has anyone seen anything like this? I can't imagine giving up the plane entirely. It's excellent.
All this re-installing to have this unexpected problem crop up is really annoying. I've tried changing various settings, tweaking the FS9.CFG again and nothing is impacting it.
I should point out that I also tried a re-install from C: (on a SATA drive with lots of room) to my D: which has a lot more room but is a standard ATA drive and then back to C: again. Neither spot made any difference.
