Yes.... I understand that this spec is not mainstream.  However, there *are*, in fact, a pretty active multi-monitor core of players that play with multi-monitors on both Nvidia and AMD.   Although I don't expect "special" treatment (I bought this great game even knowing the multi-monitor issues), it never hurts to ask.  I know many devs have the HUD scale and place correctly when played on multi-monitor setups.  When I've read the comment threads about it, they usually say that moving HUD elements is not a big deal;  they just plan for it during development.
For example, I know 3D setups are relatively rare, but Crytek built it into the engine.  And although not "pure" 3D (i.e. allowing users to adjust depth and effect), I am grateful they took the time to include it in the game.  I find the effect enhances the playing experience and the hit on fps is VERY minimal.  Playing this at 6000x1080 in 3D at playable fps (mid-30ish) on high (expect shadows on mid) is amazing, IMHO.
I thought that the devs sometimes might look at the forum and I'm just curious why in MP and not SP re: the HUD.
Hopefully they will still see this.
