Well I upgraded my Imaginsims KATL today to version 2. Even though it was stated that they made performance improvements to it I am not seeing it and if anything am now getting worse performance than before the upgrade. I have not looked at it at night yet to check out the new lighting it is to have so I cant speak for that yet. I had a issue when doing the upgrade I ended up with 3 AFCADS installed for it, the old one that allows for parked aircraft and the other that does not and the new one. I emailed them and was quickly instructed which was the proper files to use. The one major thing I am seeing is that it seems that when starting a flight there that I am not seeing the huge initial release of AI to depart all at one time which really helps with the inbound traffic as far as allowing them to actually taxi back to the gate and not just sit dormant after landing due to the gobs of departing traffic I was seeing before the upgrade. I plan on testing it more to confirm this but I have noticed the same results now 2 times where the departing traffic seems more reasonable. I am using UT2 for my traffic at 100% commercial/ga as well as 100% ga traffic from the default fsx as UT2 ga traffic is very sparse. Are any of you others seeing the drop in performance as well?

Not a big fan of the new night lighting either. :(

I haven't upgraded yet. I never had performance issue with the first version. KLGA, that's a different story - they should have updated it first. I would say the difference in traffic movement probably has nothing to do with the scenery though. That's a UT2 issue - another upgrade I haven't' had time to install. Gotta love grad school. Where am I going for spring break? In to FS world.
