Through an OSSC you should see a difference! :-) There's no fundamental reason emulators need to have lots of lag. Often the culprit is a controller or controller converter that has a inherent input lag. Also your video / audio output configuration (triple buffering etc.) can introduce lag. And of course your choice of display. There are also emulation features like run-ahead, frame delay etc. unique to software emulation that can even reduce the latency below original hardware or FPGA recreations in some circumstances. Many systems have basically perfect emulators. For some we even have emulators where there should be no known deviations whatsoever (pretty sure bsnes/higan are at that stage). I think N64/PS1 are not quite there yet, but certainly nothing game breaking like a triple jump not working. I think it's fun to just keep trying different setups. Playing retro games on a giant 2020 TV can be just as fun as using an ancient CRT. Emulation can allow for fun things like higher resolution, endless controller options and rewind/save-state, but original hardware also has its charms.
