My thoughts:
Good graphics - perhaps a little too realistic because enemy player visibilty is very bad (like BF V)
Colour is bad - game looks washed out
I get 85fps at 4k ultra settings with a 5090/9950X3D
Looks and plays like BF3 - in fact it feels like a BF3 DLC with better graphics
Movement is excellent
TTK is low which is good
Destruction is excellent
Probably too much cover - sniper campers are going to dominate this game
The games are short (only 30 minutes or so) which I think is good, but most would disagree
More milsim than previous battlefields
Menu for keybinds is terrible - so many duplicates
Gunsmith system is badly designed
No server browser and matchmaking takes ages (upto 5 minutes)
Classes taking any gun is bad
Support (Medic & Supply) being combined into one class is badly designed
Generally I just don't like the maps. I can't put my finger on why but I haven't found the game fun to play. I don't know how many there are in this play test but I have played different ones on Conquest, Breakthrough and Domination modes. I believe they might be changing the maps tomorrow.
So far there's nothing really new or innovative, same old Battlefield and feels like a continuation with graphical progression on from BF3 with minor tweaks.
Despite my criticisms, it is an early Alpha, the game isn't out for another year and here's hoping this might shape up to be the best BF ever on release.
