You mean the bug hits harder?

And yeah it really sucks on the Cayman...

Yes, it hits harder the harder you brake. I've replicated it numerous times online at the same corners in Vallelunga braking so hard that I tapped the paddle shifter twice after the first miss shift to try to go into 2nd from 3rd but 3rd dragged me on. By the time it popped into 2nd I was just about off track.

One time I nearly blew the gearbox when it slotted into 2nd quickly. Done this a few times.
 
I just read that whole thread and I for one do not want to be in the middle of that argument.

I see the same issue is there that quite often pops up here, PC users telling console users they don't have any problem at all because it is fine on PC.

Perhaps you should post a link to this thread on that site instead ;-) You never know, perhaps you would convince Steffano to become a member here ;-)

Totally get that.. haha.

It is just sad when Stefano is there asking a simple question to help him troubleshoot the issue and no one complaining about the problem will provide him that basic information. They have his direct attention .. take advantage.

Yeah it seems like he's trying to talk to a 2 year old.

Well, hopefully it's resolved sooner rather than later. I would have to imagine that it's quite an annoying bug.

Like a lot of things, until it actually happens to you, you can't really appreciate the full implication. This is why I started this thread because I too discounted the "moaning" as people not understanding the DSP.

I also should add it has not occurred since and I have spent two nights online trying to replicate it at the same track.

Blip the gas before you downshift. Works for me.
 
I always recommend to new PC players and new Console players alike. When you get on the track in your car, before you even select first gear just give your pedals a push to the floor. Better to take the 2 seconds before moving than find out you have a pedal that AC is not in sync with.

Before anyone gets their panties in a bunch, I'm not suggesting that I have a fix for this particular issue, but to hop on TT92's original post, pedal's that aren't synced properly can lead to all sorts of craziness. I learned about pushing the pedals to the floor when I was playing GT6 a couple of years back. Every now and then I would just touch my foot to the brake pedal and I was locking up. I was a total n00b at the time. I had no clue what was going on. Someone told me to step on my pedals before leaving the Pits -- I've never had that particular problem again...it's now just a habit.

To me it feels like the car won't downshift if the ABS is doing its duty. I'm actually not sure how a real-life sequential gearbox reacts in that scenario.

I guess we can check this in the Cayman that has the manual clutch.
 
I'm still not convinced... I'm not sure if its even related to the DSP! So trying to prove it is could be a futile task.
I do still believe there is a problem though.

looking at the thread in AC support forum, I can see why people do not get involved, To me it feels like console users first have to have an argument with the PC users, and convince them think from a console perspective! Then try and get the attention of the Dev team :indiff:

I've not been in the forum much, but i hope it doesn't go the way "another" dedicated sim Forum did!

Indeed, sometimes I get so used to having to press the paddle 4-5 times at the same corner every lap that when it does actually register my requested shifts.. :eek:
 
Did you try it? I don't have the problem and you can't replicate it again. So don't take my advice. Just don't go PCARS again.

Do you have trouble understanding written English?

You said "Blip the gas before you downshift."

I then asked a simple question "What does "Auto Blip" do then when turned on?"

You then start dribbling on about "PCARS" and not taking your advice. <shrug>

Hey,I don't have the problem, you do! Seems every game you get is constant issues.No I can read and write English.
Good luck with your game.
 
What does "Auto Blip" do then when turned on?

It's supposed to blip the throttle during a downshift to rev match the engine, like you would do when during heal/toe downshifts. I sometimes use it when I'm using my sequential shifter on older cars and don't feel like manually blipping, without it the engine spins up quickly once the lower gear engages and it can cause the rears to hop. I'm presuming it functions the same on consoles but can't say for sure as I've not played it.
 
From my (limited) understanding, autoblip is to match or raise engine revs to engage and sync drive smoothly.

I believe it aids in stability of the car when decelerating hard. I've often found that if it's not done well (manual heel and toe), it can cause the back end to step out (RWD cars)

So having this on means you don't need to perform correct heel and toe when braking.

question - does this downshift problem happen with wheels other than thrustmaster? I get it pretty bad on the lotus exos s1 and have noticed it occasionally on other faster cars with short braking distances. I have a t300 and it never happened before 1.10 update.

I was trying a few cars to see if I could produce the issue. I will have to give the Lotus Exos S1 a try.. I was driving the Porsche 918 Spyder which is some crazy Hybrid Super car.. it has a long power band so I did run into the downshift protection a few times until I got the braking/rev/downshift timing down. So I have not yet seen the bug.

I do believe there is a bug somewhere and working in QA it is my nature to try and figure out what is going on.

Thing is some people who have never played a racing game that incorporates downshift protection are used to being able to just quickly downshift at any time are inflating the reports. I remember watching some of the drivers on one of the first seasons of the Gran Turismo reality TV show get pissed off at the real life 370z they were driving because they could not downshift under full throttle and complained they were screwed by a faulty car. They were in the wrong gear going (out of) the corner and tried to floor it and wanted to be able to downshift without letting off the throttle at all.

Hi Hobbsys! :D
 
I know exactly what your saying with respect to people who fire down the gears, and I know this is just may just be another person saying they have a problem with downshifting...

But I know myself, I have encountered this unusual behaviour. I know how to drive (properly) and am confident that my driving is consistent enough to detect unexpected results. I'm not sure if it is the DSP, I think it's perhaps a combination of other things that make it look like it's the DSP, but I'm with you about wanting to understand what and why, if only for my own benefit.
 
Anyone noticing improvement after 1.11?

The problem came accidentally, maybe it can be fixed accidentally, too? :lol:
 
Sadly I did not test it but the other Cayman with the manual clutch doesn't have this problem.
I'm pretty sure I got the bug in the 911 GT1, whatever trans that thing has. Does seem to happen typically when ABS is kicking hard.

I think we should clarify this PS4 (and possibly Xbone) problem a little clearer so we all know what we are talking about.

There are two distinct issues and everyone is confusing them, especially when the PC guys chip in and tell us we don't know what we are talking about.

Issue 1) Which a lot of people are experiencing, is the lack of downshift when using paddle shifters at or near maximum revs. This is an over zealous DSP (Down Shift Protection) mechanism cutting in. I get this regularly and some cars are worse than others (sometimes).

Issue 2) This is the one that some people have experienced (me included) where the car will not downshift until you are going very slow and are at approximately half revs or lower. Makes the car almost undriveable and this is what I have reported the possible fix for here. If you have had this you will definitely know you had it. It is that bad.

It also appears to be on T150/300s and G29s (from what I have read here and on the official forum).

Another issue that needs to be addressed here is that Consoles and PCs are on totally different software and what happens in one doesn't necessarily transpose to the other. Even though consoles are supposed to be a few updates behind PCs it still isn't the same. So having PC guys (as helpful as they think they are) telling us we don't have a problem or in some way imagining it is not very helpful or productive. Of course PS4 and XBone are slightly different as well and the XBone isn't quite as powerful as the PS4 so also introducing issues.

I hope this clears the air a little ;-)

People actually brake with lots of acceleration applied?

Referring to the 370z no... They were just on too high of a gear leaving the corner and bogged down. In the specific car they used you can't downshift at full throttle. So say they were in 4th but really needed to be in 3rd to be in the power band, they would mash the paddle at full throttle trying desperately to get moving.
 
After testing the Lotus Exos S1 I found downshifting is a major problem from top gear into the slower corners e.g. turn 3 at Silverstone GP. Then I looked at the configuration and saw Auto Clutch = ON. So I switched it off and lo and behold the downshifting problem disappeared. I can remember switching it on as it provided stability for a certain car but I cannot remember which one. I will try some other cars with Auto Clutch on and off and see what gives.
