[quote='zanthor',index.php?page=Thread&postID=10637 7#post106377]The video card may indeed be the issue here since you are using a 32 bit OS. If the lost memory is pushing you below 3GB (it should be) physical ram, then running 5 clients on the machine would cause it to start paging memory which is where you take a huge hit on performance.
I'd be curious to see how it performed with a 512GB card, or with Vista 64 on it instead.
Other than that, the best advice has already been given...
/console maxfps 30
/console maxfpsbk 15 (I chose 15 because @ 12 I'd sometimes lose /follow, but @ 15 I never do, and it's background, you don't need 30 FPS)
Setting the secondary clients to minimal graphics settings helps, turning off sound on them helps a LOT.
Another big tip, turn off the "Play sound while in background" (This may be off by default) as it disables the sound engine for 4 clients out of the 5, which makes it a lot less noisy as well as saving big CPU hits.
Another thing, since it's a quad core you have to set your affinity or WoW will only use CPU 0 & 1.

PowerShell script to create symbolically linked (mklink) copies of WoW[/url]
That thread explains how to create simlinked copies of wow, this has helped me in both performance and sanity, as you can have different settings but still access a single set of data files. You patch once, and all clients are patched. Update 1 set of addons, all are updated, etc.
