I bought the game and downloaded 1-2 days ago. I tried to connect a server but loading screens are very very long (like 5 minutes) and when loading ends it says "Session lost" or something like that. I couldn't join a single multiplayer server since i bought the game. I searched about it and everyone says reason is your PC specs (because my ping is good enough). My PC specs:
Intel Core i5-3210M 2.50 GHz
NVIDIA GT620M
4 GB RAM
I realized that i'm not able to play this game on this PC but responsible is Bohemia Interactive. Here is the Arma 3's minimum system requirements:
OS:Windows 7 SP1 (64bit)
Processor:Intel Dual-Core 2.4 GHz or AMD Dual-Core Athlon 2.5 GHz
Memory:4 GB RAM
Graphics:NVIDIA GeForce 9800GT / AMD Radeon HD 5670 / Intel HD Graphics 4000 with 512 MB VRAM
DirectX®:10
Hard Drive:20 GB free space
Audio:DirectX®-compatible on-board
So as you can see my system is enough for playing this game but like i said i can't play it. I think this system requirements on the Steam page is not true and this situation is good for game's selling. People with low PC specs buying this game by trusting this system requirements and they realizes after downloading the game that their system is not enough. What a shame.
