I understand why the recent installation of the complex 737 PMDG aircraft has resulted in reduced frame rates and longer than normal loading times.However I suspect that, to a lesser extent, ALL my aircraft are now taking longer to load and ALL now operate at slower frame rates. Not as noticable as the PMDG but nevertheless slower than before.1. Am I correct?2 I plan to double my RAM to 1024. Will that be a better answer than possibly uninstalling the PMDG 737s?My computer details are:Intel Pentium 4A 2400 MHzMemory 512 MBN'Vidia GeForce Ti 4200 AGP8X

I can't say anything about lower performance after installing PMDG, as i have it installed since some time and i do not remember anything like that.But i can say, haveing done the same myself, that mounting 1gb ram do have some nice effects on the system :)

I noticed this at times, but one thing I now do on a fairly regular basis which has helped, is to defragment the disk about once or twice a month, depending on how often you fly. I use XP (I do not know what you use), but I found that after defraging, the performance also shot up a fair bit. Using the 737NG, as well as big addon sceneries like NL2000 etc, tend to be quite disk intensive. I also have 512MB.Hope that helps in one way for you.cheers,Ronniehttp://ronnie.vandelaak.com/baw644.gif
