Why is Crash Bandicoot nSane Trilogy only running at 30 fps?

I know, on the PC version, there's no 30 fps lock. But why in all other versions? Even on the PS4pro and XBox oneX it is only 30 fps… The PS4 Pro / X box oneX about the power of a Gtx 1050ti - Gtx 1060th With a gtx 1050 ti Crash Bandicoot nSane Trilogy with the highest settings and stable 60 fps games.

I have none of the two consoles, and ask the question only out of interest.

Think because it is not split into PS4 version, Xbox version, Nintendo Switch version. Do not think it's a single console version. The switch is probably the reason
