Also, when you give chopper a waypoint and altitude he will not follow other waypoints ot it will bug somewhere in between .

Performance of multiplayer is horrible and then arma 3 comes like MINI SIMULATOR.If you set real deal like 100 players game is over before start. Or you can play it on Super computer!(3% of world population have access to this computers) Engine need to be redone

I can confirm this also, i use other vehicles to push Grayhawk to actual move.

If you ask me 3 maps. Stratis, Altis and Stratis + Altis.

anybody who served any army in the world can tell you that we have jumps in basic movement training.But you must have on your mind that you have minimum 20 kg of equipment on your back. You can jump up left or up right in getting cover.Jump over small crossings like up to 1-2 meter.

This happen to me also in default BIS missions,Multiplayer,Singleplayer,custom missions,my missions, any missions.
