Hi,Currently my system is using FS9 and AS4.5No problems with FPS 25-30.With FSX my system gets 15-20 FPS using default MS weather.Now I am considering the purchase of AS6.5 to use with both FS9 and FSX. I know I am long overdue for an upgrade.I would like to know if there would be a FPS performance hit for FS9 and FSX. What could be expected using AS6.5?Because I have not upgraded to ASV or AS6 I do not know if FPS were basically the same, higher, or lower between these versions.My last option would be to wait until my system is upgraded or I get a new one.Dell 3GHz, 1Gb, PCI express 128Mb.

Hi,Thanks for your interest!! I think you should be good with both versions of FS. For FS04 you can adjust the cloud resolution and if you are getting 15-20 in FSX that is good also.Thanks,Jimhttp://www.hifisim.com/Active Sky V6 Development Team Active Sky V6 Proud SupporterHiFi Beta TeamRadar Contact Supporter: http://www.jdtllc.com/AirSource Member: http://www.air-source.us/FSEconomy Member:http://www.fseconomy.com/
