I've just been wandering about the area just outside Stonetooth Fortress where the spiders are. I was by the fallen tree where a chest sometimes spawns where I realised I could see no mobs, not a single spider.
Wandering a bit further I heard the sound of a mob aggroing me and from out of nowhere some three or four feet away a spider suddenly appeared: and no, these are 'stealth' mobs.
After dealing with I moved a bit further and saw several spiders maybe 30 feet away, but as I approached them they just vanished, while looking back where I had just been I could now see spiders!
It's like a reverse 'depth of view' effect, the beyond a threshold I could see mobs, less than that I couldn't. I'm also noticing players and NPCs appear out of nowhere like I've never seen before this update. I see no 'lag' or 'latency'.
Also, maybe related, maybe not, on the character selection screen there's a pause of a second or more from clicking a character plate on the right to the scene changing and the character being shown, again I've never seen this at all before this update.
