running FSX on Vista 32bit now but thinking moving to Vista x64, any potential issues with FSX?
YES - DRIVERS
I've been running Vista 32 for about 7 months and have mine tweaked and pc oc'd - been running great for some time now.......................
Good luck and keep us posted.
The 64 bit drivers are nearly a non-issue now. In general the Nvidia display drivers are every bit as stable and compatible as the 32 bit.
