I can't confirm that this is MSAA related but performance has definitely been worse and there's been a lot more micro-stuttering present since the last update.

@Geez I’m having this same issue, along with massive stuttering.

I also tested on a local LAN server with just me, no mods, and there is a huge drop in performance.
