Great. More physical drives is an excellent strategy. OK, you probably do not want to "swap" across physical drives. For maximum efficiency, it helps to keep your C: drive as clean and unfragmented as possible. Install most of your programs on a physical drive that is separate from your boot drive, and then keep all your "data" (Vue scenes, etc.) on a third drive. But, for most of us, the greatest gain is to take a look at the "background" processes running, when you have Vue loaded. (That is, hit Cntrl-Alt-Del to bring up the Task Manager, and then take a look at the list under the "Processes" tab.) It is very likely that a lot of junk is running that you don't need, when you're running Vue. Some typical stuff might be printer processes, especially is you have a multi-function printer, dumb things like the Windows Messenger Service, and so forth. If I'm doing a big render, I will make sure that I'm disconnected from my internet comm, and go so far as to kill my firewall and anti-virus.) I've got to head to bed now, but if you like, tomorrow, I can return to this thread and show you how to tell what all those cryptic processes are. ????????
