(The following is @PoisonBill; Ts4EVER ninja'd me) No, there actually is very little room for improvements, due to the high view distances, large amounts of objects, huge maps, lots of effects and things happening at any given time, and people already having performance issues.
Honestly, while I'm sad PR didn't win, FH2 certainly deserved it too. It's a shame we didn't make it, but look at it this way, we won the upcoming awards with PR:A2, will likely win MotY in, I guess, around two years with PR:A2, and eventually perhaps Indie of the Year with PR2. Still plenty of things to win even if they ruled out a second victory for PR:BF2. And we can rest assured that there'll be a honourable mention every year

Give the other mod teams their screen time, too. PR is so awesome, if it won every year the whole competition would become kinda pointless
