Hmm, I was going to suggest the mccc option but you've already seen how janky it can be. Still, I think it's a bit of an acquired taste, especially when you tweak the decay rates and such, too. I've been using 40ish for my game speed, I think, and as long as you don't use the speedup features too much (or ever, really) it works pretty well in making the days last longer. Still some jank here and there but again, acquired taste.
of course, e'erybody plays differently. just try going up in increments on game speed until you find a sweet spot. Just know that there will still be some jankiness no matter what, but it's the best option we've got currently.
