Here how it works.

You can enable H shifter in the control options screen if you have it.



Then the sim will automatically enable for cars that have physics for manual gearbox.

It will also autmatically disable the H shifter and force you to change gear with paddles for cars that have semiautomatic or sequential gearboxes.



For such cars you could use the clutch manually but it makes no sense you won't gain any speed. The gearshifts on such gearboxes have specific timings for up and downshifts.



Also, if you use say autoclutch operation for such gearboxes the gearshift get slightly delayed because of some "induced" clutch slip



Regarding the clutch in a button it is still debated in our team... I don't like the mentality behind it, but in the end even if you force it to an axis as it is now, somebody could make the axis on/off in the end, so why make people frustrated... we'll see. I don't think it makes you faster though...



It's pretty simple really. We tried to make it as simple and straightforward and in a way, "forcing" the user to get more realistic
