Dear FSX colleagues: I'm afraid I have only good reviews about FSX BOOSTER and XTREME FSX PC which I use in conjunction with nHancer. My Frame Rates have kept well within acceptable range even when dealing with troublesome airports like London's Heathrow which previously used to cause havoc with my flying. My FR would plunge to about 4 whenever I used FSX.NOW even with complicated large airplanes it remains an acceptable 17-20 FR in or around Heathrow. With other more forgiving airport environments it is even more useful. What really pleases me is the fact that now it takes me about 5 seconds to start FSX AND also 4-5 seconds to display the FREE FLIGHT window. Both systems have indeed improved my playing. I am running Windows 7 Ultimate 32-bit, Intel Core Duo CPU E8500 @3.16Hz, memory 4096MB RAM. A modest GeForce 9600 GT card. I REGULARLY DEFRAG my system and also run FSX discs and "repair" my FSX software, incuding my FSX Acceleration addon. I do believe this is a marked improvement on what I had before. I'm not a well versed PC enthusiast and I do appreciate this extra help. I think that I could do even better with a better card than the one I have now (nvidia GeForce 9600 GT) . Any suggestions would be appreciated. Thanks
