is this possible?

i hate to be the bearer of bad news, but if all your clients are in dx11, then they are ALL running on the 480 and being crossed over to the 260 because no matter what drivers your running the 260 will never support anything above dx9

DX11 is a viable option in the drop-down menu of WoW's Graphics Options while running a GTX 260. I only know this
because I have 2 sitting in my closet. If a card doesn't support DX11 at all (even through emulation) then that drop-
down menu will be completely darkened out (unavailable).

sorry for the post spam, but i think the reason i don't get a perf hit on cross monitor switching is due to my cpu/ etc. with more cores and faster clock rates, the occasional software rendering becomes trivial, mostly i guess to the fact that wow is more cpu intensive than gpu anyway. you can max all clients out and most of the time never hit 100% on your gpu unless there are like 200+ units to render

You could be right about faster CPUs being able to handle software rendering better because I haven't tried it since I
upgraded to this 2600. With this recent discussion I'm tempted to do more testing to see what I can come up with.

This must have been a recent change. I positively remember looking at that option when i was running 2 pc's and the slave pc having gtx280's in sli, the option was greyed out. i jst turned that box on and now its viable. i apologize for the mis-information
