There is a Microsoft hot fix for Vista for video cards that have more than 2 Mbs of memory especially applicable to the GTX.

...John, do you have the "hot fix" specs for this issue. I have had some problems (not with Trainz) but other games crashing to desktop and am baffled by this - Vista Premium 32 bit - is my system. These 'crashes' occur after the game has been playing for a short time and always with the same message. I have one of the tech support people on it for one of the games in question but as of this writing nothing has been resolved.
Thanks,
Roy
