I think it has improved a bit. Some things I did notice, and I will try to be specific to make it more tangible.
For many people the med-packs are not shown, they do seem to work (although invisible).
Sometimes the body of your enemy disappears, literally. So you don't need to gib. But you cant pickup their gun for ammo either.
Sometimes this happens to a player. I was shooting this medic, when suddenly WOOSH, gone. No body, no sound, no notification of self-kill or any of that. Just vanished instantly. Not even a weapon on the floor.
Walking into teammates is still sticky, hitboxes are still off.
All these things happened on a 7 vs 7 session, so not too many people online actually.. Well, hope this can be of any help.
Also, I do hear a lot of complains on the forum as well as online, and people are actually leaving the server due to the problems. Even members start to leave our community right now. I don't want to be the bad guy, but I think we should be critical here. The current approach to the development seems to come with a high cost and maybe the costs are starting to get too high. Can we think of a solution for this? Members leaving our clan is probably not what we want.
