How much would 64-bit actually matter?

[rkman]

Most mods work just fine with 64 bit..

..on some rigs, not on others. You mileage may vary wildly when running the 64bit player.

You could say the same for any mod though to be fair, use at your own risk. Some mods, just don't work for me, and I know it must just be my PC as plenty of other people report they work fine.

What I would really like to see, is either multi-threaded physics calculations or (preferably), offload the physics to my GPU. I know some graphics cards don't support physx, but there is no reason it can't fall back on CPU if a compatible GPU isn't available.

If we're running a 64 bit OS, does the 64 bit client download automatically or is it a build y'all are getting from somewhere else?

A modder hacked in the 64-bit version to work. The whole thread can be found here: http://forum.kerbalspaceprogram.com/threads/82118-KSP-64bits-on-Windows-%28this-time-it-s-not-a-request%29

I hear the latest unity will have multi threaded phys-x so there`s that...
