I've only done two matches but I thought I'd start getting impressions down.
- Performance is better, although still poor. With the new options I'd describe the experience as playable. I still get the occasional frame drop.
- Hitreg is dramatically improved. I have not had an episode of bad hitreg yet.
- New voice lines are great, hope to see more.
- Various UI improvements are nice — tooltips and gamemode descriptions on loading screens, more legible objective status text. More great signs that feedback is being read.
Edit: Armor is now mostly useless. 5.56 has the same TTK vs armored or unarmored based on pvp gameplay and testing on bots.
