I haven't had a chance to do much with the 32-bit install yet (real life intrudes) but it is both blisteringly fast, and a very easy install. I have seen no problems at all with what little I have done.
Given that I am running windows 7 Pro 64-bit on a moderately scaled workstation:
I think that I would only bother with a 64-bit version if it were available for the other operating systems, and if there were some genuine advantage to a 64-bit version - such as speed, extended precision maths, storage etc. Game writers might have more to say about that, though. I'm not sure what advantages might be available with a 64-bit install.
Going forward, I can see backward compatability with 32-bit processors going the way 16-bit support in Windows has been dropped (and woe betide anyone who actually has 8-bit software for a PC
) - and at that time, I guess a 64-bit version will be necessary.
While I would
like to install a 64-bit version, right now, the 32-bit version of SB is perfectly sufficient. (mind you,
all of my development is using 32-bit software - VB6, mainly).
My bottom line: I believe that a 64-bit SB install will be necessary at some point, so now is probably a good time to get started - before it becomes the only version acceptable under Windows 11, 12 or whatever. No rush.
