Apparently from what I can gather Starcraft 2 moved to UDP in a patch. Now obviously with fps games there is no dispute that UDP is the only way to go. But with RTS games what benefits does UDP give over TCP given that the network model is lockstep?

I suppose another way to phrase this is: what features of TCP make TCP inferior compared to UDP with resend, etc. implemented in the context of rts lockstep networking model?
