When you say, we recommend running this software in 64bit. I have two desk top's to work with and 4 ssd drives. Would hooking up any of the hardware/software help in a 32bit program. Who do you recommend for 64bit software. Also are any of you going to the flight sim conference in Hartford Conn @ Bradley INTL. Thanks Stanford.

I think the 64 bit recommendation is for Windows due to 32 bit Windows only having a total of 4GB of addressable memory regardless of how much is physically installed. By the time you subtract Windows' need (usually several hundred MB), you are left with a much smaller amount of usable RAM. In addition, any memory in your video card has to be subtracted as well, so if you have a 1 GB card, including Windows use you may only have 2.5GB left for FSX to run...which would be pretty much impossible.

64 bit Windows 10 has a limit of at least 128GB (up to 2TB). 64 bit Windows 7 has a minimum limit of 8GB (up to 192GB). Even though FSX/P3D are 32bit apps and therefore can only use 4GB of memory, the sim will get to use the whole 4GB (assuming you have at least 6-8 GB physically installed) if you're on 64 bit Windows.

Thank you very much. That was extremely helpful. Hope to see one of you at the Flightsim con convention in June.
