Ahh Grasshoppa', you've just begun.
Seriously, EVERY car has a little different feel. PS4 user here. So let's get that out of the way first. The only game that gives me a real feeling of clutch is Assetto Corsa. (I've driven probably 90 different manuals in real life - conservative number). Assetto seems to allow for some kind of clutch slip, which is what clutches do. Most other games have this constant bight point that's very, I don't know, digital? Like, gear engagement is on here, off here. (Gran Turismo is by far the worst, even GTSport as of last week). But that's not how real clutches work. Clutches slip based on pedal position, engine RPM, horse power, torque, etc. So far, Assetto has the only clutch I believe is sim worthy on console, because it kinda seems to slip a bit. I'm still waiting for the version that will actually let you burn up the clutch disc while slipping the clutch. Then we'll know they've modeled it properly. There's nothing like the smell of a burning worn clutch when you're trying to slip it just enough to get up a stubborn hill off road.
