Noticed a couple things:
1) Almost no recoil until you get suppressed. At which point it goes through the roof, but if you tap your burst your fire (3 max), it pretty much counters it.
2) If your looking down sight on the xm25 and get suppressed, the whole inferred picture gets stretched across my 3 screens instead of being just on the center one.
Everything feels zoomed in to me. Also feels a lot easier then BF3. Guns have almost no recoil, help is extremely easy to fly, takes a while to take a tank down. The tank damage mechanics already have me thinking it feels more like bf3 at launch then after the second patch.
I have not got to fly the apache, but the China attack helo feels very nimble like the apache does in BF3.
Best feature though is chat after round. I'm very, very happy.
edit: Set smooth gameplay to 10 and still getting shot after rounding corner.
edit 2: Dice needs to fix my mouse being in the top left corner of the left monitor when I go to choose something from the coma rose. Nothing like dragging my pointer alllllll the way from the top left corner of the left screen just to be able to set an objective.
