Clutch all wrong!? Impossible to drive manual transmission.

[Mutkanen]

Hi everyone,

I have a Logitech G29 without additional shifter, i.e. I shift with the paddles. I have a clutch pedal and I know how to use it (I drive stick shift in real life).

When driving the Lotus Elise SC or the BMW M3 E30 in Assetto Corsa, it is virtually impossible to shift up without spinning out. Here's what happens:

1. I press the clutch. (I know it works, because the revs go up, if I don't go off the throttle.)
2. I change the gear up.
3. Now it goes wrong: the rear tyres screech, the rear end kicks out and the rear wheel hubs light up red in the damage indicator.

Point 3 happens even though I have the clutch fully depressed! I tried setting the clutch to only work between 10-90%, no change. It is as if shifting would disable the clutch. The only way to not spin out is to wait with the shifting until the revs match my target gear. But that's not how it's supposed to be, I have a clutch for a reason.

Please tell me I am missing some setting!? I just can't believe that the clutch is modeled that badly in this sim. If it would be, there would be no reason whatsoever to have cars with manual transmission in this game.

Thanks,
Schuhorn

Maybe you have your 2nd gear position on your shifter assigned to the gear AND your handbrake?

[Mutkanen]

Good idea, but I just double-checked and no, I don't have the handbrake assigned at all. Also I don't use a shifter, I use the sequential up/down paddles at the wheel. And it happens with each and every gear, not just 2nd.

Are you lifting off throttle on upshifts? Check pedals app to make sure clutch is not set to auto clutch as it may be disabled with sequential shifting in some cars.

But with a seperate shifter it defintely works as intended, the problem doesn't come from poor clutch simulation by the software.

Pretty much, if set to sequential shifter it will auto clutch even if auto clutch is turned off. The clutch pedal still works, so something weird is going on with the OP settings or something.

Long time G25 user here, there's nothing wrong with the clutch, in fact I'd say it's one of the more refined mechanics of the game. You're trying to use a clutch with paddle shifters, it's only effective with h-shifter as mentioned above.

[Mr.Herbi]

This is like in real life. Paddle Shifting is not mechanical so you dont need the clutch.
If you dont have a h-shifter, every car behaves lika a car with sequential gearbox.

I think that the clutch doesnt work proper with a h-shifter because usually you can set off with just letting the clutch out slowly and sometimes giving a bit of gas to set off but on Assetto Corsa you cant you have to rev it and then let clutch out etc. Personally I think the clutch isnt simulated like real life but apart from that its a good game.

[Neawoulf]

For some reason AC has some kind of automatic parking brake, so you need a bit more power to accelerate from a complete stop and accelerating by just releasing the clutch doesn't work. I think it has something to do with the low speed physics, but i'm not sure. Stefano Casillo said something about that in one of his streams, but i can't remember all the details.

[Leagle]

Have you tried waiting half a second extra to simulate moving the stick?
Even though I was using a H-shifter I found I was shifting too fast to allow the car to actually change gears.
I can't really explain it.

The cluch look like r-factor at some moment, you can change gear at stop and any rpm it's not normal... but in assetto it's really modelised but i think it's inverted : when you dont's stop accelerate in driving and would like change gear it's working let 's cracks but not at the stop or if you roll slowly don't accelerate... it's really curious

I find that although the AC clutch doesn't operate like a RL clutch pedal (a biting point somewhere along the pedal travel range, in a slighty different place every car and with the actual biting point range anywhere from a few mm to a few inches) what it does do is simulate the biting point with the whole travel range, makes it a lot easier to launch with a bit of "Clutch slip" than it is in RL

without a serious feedback mechanism in the pedal to simulate when you feel the bite point I don't think it would be desirable to simulate the clutch like a real one

although saying that you could set large deadzones at either end of the clutch axis, where it's active will be your biting point, make sure to change it about for every car that should help

[Mutkanen]

Thanks everyone for all the input and ideas!

The pedal app was a great idea, but it only showed that AC receives the correct information. As long as I keep the clutch depressed, that's what's shown in the pedal app. Nevertheless the car behaves as if I would have suddenly let go off the clutch as soon as I pull the paddle to shift up - rear tires screech and the back steps out.

Next I decided to wipe out my profile and start from scratch to figure out, if there is anything weird in my settings. But to no avail, the problem persists.

Then I was playing around with the driving assists (auto-clutch, etc.) and have come to the conclusion that it's either a blatant bug (Nobody thought of this controller combination. Really!?) or a design decision I can't understand (AC developers deliberately 'sabotage' the driving of stick shift cars without equivalent controllers. Srsly!?).

The only real way to drive stick shift cars without an H-pattern shifter, is to turn on automatic gearbox from the driving assists - which kinda defeats the purpose.
Otherwise you will have to do some pseudo "rev matching". With auto-clutch off you need to clutch and then wait with shifting up until the revs match the next gear. With auto-clutch on you need to go off the accelerator, wait until the revs match and then shift. In reality I clutch, shift immediately and then let go off the clutch slowly to get the revs to match. There is no learning-by-heart of speed/revs/gears needed (though it will come over time and make you shift faster).

I do sincerely hope that this behavior is indeed properly modeled with an H-pattern shifter as previous commenters stated (but still wouldn't understand, why this clutch behavior would be refused to paddle drivers). Luckily I can borrow a shifter from a friend of mine for testing. I'll report back!

I still dont really understand are you saying in real cars with a h pattern manual you shift with no lift of throttle? I have never seen a manual car that allows flat shifts and you need to both lift off throttle and press clutch to change gears.

AC adds a shift delay to manual transmission cars when a h shifter isnt used so as to not give an advantage to those driving these with paddles, this also most likely means it forces autoclutch on. It would be pretty hard to manually time clutch along with the shift delay so to use the clutch on manual cars you need to have a shifter.

The clutch works perfectly properly with h-shifter...you can set the max range of the clutch to even simulate a biting point in the wheel contrlols ingame. You can 100% do a normal start with the clutch as well, you don't have to high rev it and spin the tires, it just takes the same amount of finesse as you would have with a real life car, this is coming from someone who literally got bored and experimented with it awhile back, and I tested it this morning and it still works just the same.

All of the pedals are naturally inverted and you have to tick "invert" in the menus to fix it. xD

there is some damage simulated for the clutch too...
