No pun intended, the game will freeze for several seconds or pushing close to a minute (actually writing this as the game is freezing).
Problem is whenever the temperature increases or decreases, the game freezes for a good moment and only gets worse the more districts you have (since their temp levels can change). This is even further amplified with the auto heat allocation upgrade turned on.
Lastly, using the temp display mode causes the audio to be fuzzy and causes massive FPS drops. Again, it happens with more districts in the city... Makes playing late game miserable.
I'm on console, Xbox One Series X.
