Full DualSense support was added with 1.7 update, but you need to connect it to PC via USB cable.
And yeah, I absolutely agree with

, it's amazing experience playing the game by using DualSense and especially cuz of the sound design - what they did is basically made it so that all radio calls, all tablet UI and stuff is played through DualSense's speaker, so it feels like you've a Combat-net radio on you all the time which adds to the atmosphere and immersion, and when you use your tablet to check the map, add markers and stuff, you're getting sound confirmations via speaker.
Idk why they decided to make the L2 hard to press to ready your weapon instead of R2 to work that way and pull the trigger, but whathever, I guess they have their reasons for that.
