Stuttering problem?  After which patch?  At least with me, I've never experienced this problem after any of the patches.
ack-ack
Actually I had the same issue.  And I have a fairly high end Alienware.  Maybe its a particular harware issue.  I think one of the subsequent patches improved thing significantly.  
I sorta dropped out of the loop when I heard AH was coming out with a WWI arena.  I'm several patches behind, but I think I'll fire it up and get back up to date.  
Its a visually beautiful sim.  Its screenshots look more like paintings.  
Its physics and damage models are at least equal to any, if not better than many.
The load times were a bit silly and the campaign depth was a bit shallow.  I've been waiting for it to bake a bit more.  Probably time to take another peek.
