After one day of playing:

Yes the game is slow... perhaps it's slightly new generation... or perhaps it's a debug build... or perhaps it needs some further tweaking.

I am already having a lot of fun with it and enjoying myself and that is important... 
the feel of COH1 is there but in a bit more realistic way and less bullshit.... 
it feels way more mature... and I like this feeling a lot.
 
It's well on it's way to become a true picture of world war 2 in all it's glory and horror ;) :)
  
Already loving the artilley strike symbols and fire... it feels like yeah: let's do some damage to those [filtered]s.
   
The way it fires is also way more realistic.... instead of dropping straight down... it seems to come in an arc or so... pretty cool.
 
For me as an armor commander I am loving the way I can build fuel depots/observation posts ! ;) =D 
Gives me more fuel and makes me more lethal oh yeah ! ;) =D
  
I am not sure yet if it's per player or per flag ;) :)

and the tanks look pretty cool and some even uber yeah ! ;) =D
 
some have some cool new artillery barriages... and even at guns can do that... cool ! ;) :)
