2.0 is a big task, they're rebuilding large parts of the game so it's going to take a while before it returns to the polish of the previous version. It's just really buggy right now, like Into the Radius was on release.

Thankfully they've kept all the good features and expanded on them. New gun attachments and upgrades are great, now I can make a tactical TT-30 with supressor and laser or maybe reduce the fire rate of an MP5 to make it easier to control in full auto. 
Cheaper ammo and tankier enemies makes full auto or burst fire an actual option outside of the endgame now. Mimics are plentiful even in the beginner areas so gunfights with them will play a much larger role than before, the ones with SMGs are scary when they rush you. 
Loot spawn locations are already showing a wider variety than before and new higher value loot items provide an extra reward for exploring. 
The 'Tide' has a lot of potential for making the radius feel more like a force of nature; It gets tense hearing you warning buzzer go off, knowing you can't make it back to base in time and wondering where it will spit you out. Hopefully they put a lot of effort into making that feel as cool as blowouts do in STALKER.
