AC 11 runs with approximately equal reliability under Vista 64 and XP 64 bit, but 3D Open GL is noticeably better & faster under XP, using latest Ati Radeon drivers (Catalyst 7.9).
AC does not seem to multi task very well under either platform though, even when plenty of free RAM & CPU time available on dual core PC - switching back from another large pp, or after PC has been in standby mode, performance nosedives to unusable levels under either for me.
Perhaps MAC is better?
