Well, I've got 4 GB RAM, and 12 GB of virtual distributed over 3 disks on my Athlon64 1 GB ram, 3 GB virtual on my AhtlonXP2700+ 1.5 GB RAM, 3 GB virtual on my P4 2.8 HTT FSB800. Min and max are the same. Main advantage: no fragmentation of the swapfile. When Windows has to expand the swapfile, fragmentation can kick in. When you shut down Windows, the expanded part is deleted and your swapfile goes back to minimum size. No single process on WinXP can use more than 2 GB at a time (under normal circumstances. There are exceptions). Rendering often comes pretty close to those 2 GB (I've seen 1.8 GB memory use in a Poser render, 1.9 GB in a Vue render). So other processes must be swapped out. Parts of your rendering app also get swapped out, including data. A better rule of thumb is: your swap file should be at least the size of all the processes you run at the same time. So yes, with 2048 RAM I'd advise a virtual memory size of more than 2 GB.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
