N64 on rpi3 perfect, on rpi4 slowed down as hell

[neo207]

Hello. Can anyone help out? N64 runs with probably 5% speed while dreamcast is no problem.
I have my old rpi3 here, everything works perfect - on the new rpi4 everythings messed up, toooo slow and stuttering...

roms are the same, everything else is perfect so what could that be`?
