Only 2 real problems encountered in this Beta:

Had to deconnect my Thrustmaster HOTAS because for some reason it interfered with the mouse controls... Might be calibration issue, but it doesn't happen in other games.

For some reason my character kept trying to pick up ammo drops from fallen enemies, while they were already taken. It would not be a major problem, but it prevented me from picking up the body to maintain stealth. It occured with 4 or 4 bodies on the same spot.

For the rest it went reasonably smooth.
