To clarify, Timers are just timedelta between frames added to a single number (the timer name).
They have always been impacted by game slowdown below minimum framerate, so if your game drops below your minimum framerate on one system (mobile) but doesn’t on another (pc), the system that didn’t drop framerate will have the more accurate timer (and therefore increase “faster” than the other).
I don’t believe they should be impacted if you don’t drop below the minimum framerate though.
