So can I assume it can run higher than that? My system is set to 120 and that is where most games run, but TS-2020 runs at a steady 60.
It depends on what routes you drive on. Some routes like Cajun Pass have high frame rates because the scenery is not very dense but if you drive a route like Portsmouth Direct I think it is where the scenery is very dense you get quite a big frame rates hit. Also electrified routes in stations with a lot of wires all over the place can hit your frame rates.
