If this one have been talked about, i'm sorry about that, and please redirect me there.I have using FS9 for 2 years, but these days, i found it running abnormally for me. Here are the conditions:1. The FS loads so slowly, especially during loading a flight, where usually stucks at 98% for almost 5 minutes or so.2. FS seems to heavily need more power to render everything. This is especially with the clouds.3. It stutters so much that even trying to record a flight will just producing crap videoFor your information, here is my specification so far:AMD Athlon 64 X2 +4100 (2.11GHz)NVidia GeForce 8500GT 512MB3GB of RAMWindows XP Professional SP3FS9 + REX FS2004If you need screenshots of the FS9 settings, i can give upload it ASAP.Thanks.

If I remember correctly, loading at the end is AI traffic. Have you installed any new AI lately?

a 'quick and easy' fix for many/most FS issues is to remove the FS9.cfg file to your desktop. start FS. FS is know 'reset' to, mostly, as first installed condition and created a new cfg file.see how thing run.add you FS9.cfg 'hacks' one by one, testing after each edit, and see if you can find the problem.--

Well, i install all WOAI packages that they offer on their website, except the no longer working airline. :(

I'll try this one too. Be back with the report ASAP.EDIT: scoob's suggestion works marvelous. Now it run much faster than it was, especially at the 98% stuck problem. But, i'll try the tuneup again now to allow me to find what setting slows FS9 down.
