Oh [censored], hey Sakiri! Are you still around? I just remembered something.
Which patch did you install? Did you ditch the original patches (you know, there was one patch for the base game, one for Dawnguard, one for Hearthfire, and one for Dragonborn)? Did you replace these with some sort of all-in-one patch?
I forget its name, but I also installed that same patch last year, and it wreaked havoc in my game. I could not go from one cell to another without a freeze or a crash. I also noticed some mad stuttering, just like you say in the OP. My only solution was to get rid of that all-in-one and put the old patches back in.

I haven't been keeping up with what's going on at Nexus, but apparently that new patch doesn't always 'play nice' with older mods.
I also am noticing it sounds like you're using the SE version. I am not. I've got the original version, whatever it's called. Anyway, my advice might not work if you've got SE.
....Also, if you're still not seeing the Warmth and other meters, did you try switching from Contextual to "Always On"? I'm thinking that patch may have reset your original Frostfall settings, and Contextual is what the MCM defaults to (I think).
