Why the simutrans folks decided on a weird hardcoded frame rate (40fps) that looks janky as hell on every single display ever I will never understand. Unplayable. instant motion sickness.
It sounds to me like a product of the ‘90s. CRTs were still common, and they support essentially arbitrary fixed refresh rates. It wouldn’t have been a big deal at the time. It’s like how the original Doom runs at a native 35fps when you don’t use interpolation.
I haven’t played simultrans, but I wonder if it feels less janky on a 120 Hz or 240 Hz monitor, since both of those values are evenly divisible by 40. Compared to playing on a 60 Hz display or other non-multiple of 40 refresh rate monitors.
Ever heard of little games called Diablo 1 and 2? People spent billions of hours playing those on displays with framerates faster than 25 for 2 decades.
