My game will be running fine, until it's a few days into Winter. Then it is SLOW, and freezes (sort of) every 5 sim minutes. It's even worse with deep snow. Has this happened to anyone else?

I actually had to turn snow off in some of my worlds because it ends up lagging my game so terribly. I know it's a graphics card thing, though.

The snow itself isn't so bad for me amazingly, but changing into outerwear? Oh dear God. Especially when inviting other Sims over to my active household. If a Sim has to change into outerwear off the active lot, like say after work, if I'm not zooming right in to watch them change (Goddamn it stop making me a pervert Sims) they just stand there like a lemon for literal Sim hours. Same for inactives. It's like they're too scared to get changed without their mummy god type person to make sure they don't throttle themselves with their winter pants or something.

I don't get any lag, but I can't talk because my computer's a brand-new handbuilt desktop (then again, on the old workhorse, it didn't lag terribly either). I learnt this trick a while back, but if you pause for three seconds while your sim is stalling to change (they can stand there for a few hours otherwise), and then unpause, your sim will change *snaps* like that.

My game also lags during winter. And I don't even want to talk about gift giving parties. oh dear god.

Only three seconds?! It takes about a minute of pausing for me.
