I am so pissed that the U.S. is excluded !!! WTF - Everytime something is going on GTwise it's not happening here or it is delayed - WHY DOES POLYHPONY NOT LIKE THE U.S.???

*Yawn* Done to death.

Glad to see the DFP can still be used competitively against the G25 - there is no way on earth I can afford the G25 but I've been looking at the DFP as a likely choice.

My problem now is having the space for a wheel and pedals.I have nowhere at all to mount it with my current setup so the wheel will have to be going on my knees...
 
Can I just confirm that I am using a G25 but have not yet tried a lap using the clutch - as I mentioned in a previous post I have nowhere to mount the gear lever so I'm using paddles for now. This competition has a few weeks left to run so if things are getting desperate later on I'll have to learn to use the clutch. Just haven't got the time at the moment though.
 
i think everyones running out and buying the g25 just for this my self included, alot of places sold out on the net, now.
 
I'm gonna have to save up and get the G25 aswell didnt know that the clutch would give that much advantage. Does anyone know roughly how much seconds you could shave with the G25 on one lap?

I just watched Andy's new time and he indeed is using the clutch and first to do so. Congrats to him for adapting so well and quickly, he could probably get down to a fastyfast time and also stand a chance against the best in the next stage.

PD seem to use the G25 at demos, but could they make people use the new DFGT with just two pedals for the next stage.
 
Got my G25 today.

What I've found is that I can't really use paddles/sequential with it when I have my shoes on - which I prefer since the brake has a lot more resistance than my previous pedals. My left foot can't fit on the brake pedal when my right is near the accelerator without the clutch getting in the way. I suppose it makes me use the H-box though, lol. Only really had about an hours practice, but I got down to what I was lapping yesterday with my old GT3 wheel and paddles. This was without heel-toe. I'm not sure if it's the 900* rotation or the H-box but something has definitely improved so my times are more consistent, it's only a matter of time before I get below what I put yesterday (which was a fluke lap).
 
Hi profi!

Pad vs. wheel with clutch research

After about 600 laps of further practising let me add the following:

:crazy:

I've got my EU-version last friday and I'm now 150 laps into Eiger and have
done a 1'22:718 with the pad.

I am sure nobody using a pad will do any better than 1.22.xxx

I guess, you will be proven wrong here (in the end). Two laps after my
fastest one I had a -0.5s on the clock after passing the bridge, staying
close behind l1a2r3's ghost. Unfortunately, I didn't managed the first
turn after the tunnel. :banghead:

Up until now, I had no single perfect lap were I could clue it all together. :scared:
Btw; I don't mean teH perfect lap. ;)

I'm now going for a low 22, high 21. 👍

I did a 1.22.6xx utilizing the sixasis and comparing this lap to ALL of the german top-ten replays I can see the difference very clear:

Using a clutch and therewith the technigue of shifting gears without letting the revelations drop inbetween shifting simply gives an advantage in acceleration.

..and the Eiger Track is all about accelerating !

My lap (sixasis) compared to a 1.20.xxx (clutch shifter) :

Getting into control right after the last curve and accelerating onto the start-finish straight the shifting point is just a few meters before the start-finish line.

The Ghost is invisible because im up with him.
Shifting (..into 3rd gear)

The Ghost becomes visible close ahead (a few meters)

Until here theres no problem with traction so the cause of loosing a few meters compared to the ghost is not loosing traction - its simply slower acceleration.

Over the jump...

I manage to overtake (!) the ghost while going into hairpin one (right turn) and afterwards into hairpin two (tight left turn)

(definition: ghost := l1a2r3-1'20.469-ghost)

Are you sure you managed to overtake the ghost? Have you seen
the ghost in one of the mirrors?

Accelerating.... (2nd gear)

No shifting on the short straight down the hill, just going to the left hand side of the track without loosing traction is the key here.

Yep.

I can also manage to stay up with the ghost, but only up until corner exit.
He can better accelerate down the straight without loosing traction.

3rd hairpin (right turn)....

I am up with the ghost (!), he is invisible.

Nice!

(The very difficult..) acceleration onto and over the bridge...

The ghost outperforms me at this part clearly. Shifting from 2nd gear into 3rd gear and afterwards accelerating a (relatively) long distance shows the difference ! At the apex of the following right turn (lowest part of the track) I am clearly behind the ghost. (..some tenth of a second)

Me, too. This left-right turn is really about proper weight shifting and tight
acceleration.

Remark: there is no way to keep up with him on this straight !

Going through the right turn...

Dont loose traction, dont get into sliding !

Quite interesting, I can drive through this turn slightly faster then l1a2r3! ...

Accelerating up the hill onto the tunnel...

Switching from 2nd gear into 3rd up the hill and inside the tunnel repeats the "drop-behind" again. The ghost outperforms me here the same way as on the straight before.

... And I can keep the distance, at least.

But here the advantage in accelearation gets even more clear because its going uphill.

I am loosing some more tenth of a second.

The right-left-right turns after the tunnel...

It is indeed not easy to get through these esses without sliding and loosing traction. But I can handle it with my sixasis so that the gap between me and the ghost while braking into the first of the two last right turns remains (visually) equal.

For me, this is the trickiest part so far (but not the hardest part). The exit
of the left-turn is somewhat difficult for me in managing the weight of the
car by proper steering. From the replay of l1a2r3's ghost one can clearly
see that he profits from the higher steering-resolution of the wheel. I can't
do this kind of steering with the pad.

Going through the double-right and accelerating onto the start-finish line..

The point of switching gears (from 2nd into 3rd) is now a bit earlier than in the (opening) lap before and a good distance before the finish-line.

The double-right is not a real problem for me. You only have to shift/throw
the weight of the car properly to the outside on entering the second
right-turn.

The ghosts of the top 2 players (doing 1.20.4xx / 1.20.6xx) manage to get into 4th gear after the jump (!).

I get into 4th gear within the jump.

So I have to ask PD:

- Why is it possible to switch gears faster with a wheel/clutch ?
- Why is it possible to use a technique for bringing the revs up inbetween shifting with a wheel/clutch ?
- Why is it possible to enhance the physical performance of a car with a wheel/clutch ?
- Why do pad users have to get a (software caused) disadvantage in acceleration although they already have a disadvantage when it comes to sensitive control / forcefeedback compared to a wheel/clutch device ?
- Why is there a competition where only the wheel/clutch owners are competitive and able to win ?
- Why do I have to own a wheel/clutch for beeing competitive ?

Despite there are some advantages in using the clutch, for me, it breaks
down to the following; acceleration and steering.
Further, a wheel has a much higher resolution (sampling rate) for the
paddles as well as for the steering wheel itself! A high resolution for the
paddles gives a better control over acceleration out of a turn. A high
resolution steering wheel allows for a smooth turn-in and a better control
of weight shifting. On the contrary, the pad's shoulder-buttons /
analog-sticks have a rather low resolution.

(The next issue should be its own thread.)

PS3 <-> pad/wheel input-lag issues

I assume that a wheel has an even smaller input-lag compared to a pad.
Input-lag: "the time required until a change is recognized", a.k.a.
on-the-button-feel. LCDs and TFTs do also suffer from input-lag, in the
range of 20 - 60ms (~ 1 - 4 frames at 60Hz). Most large LCDs have a
very high input-lag (~ 100ms = ~ 6 frames at 60 Hz). Adding it all
together gives a rather large input-lag in total. A lag of 60ms is already
quite too high. 20ms is acceptable. 1 frame = 16.6ms at 60Hz.

I do play on a 22" TFT featuring a TN panel. TN panels have the smallest
input-lag along all known panels (like PVA, IPS, etc.). There exits some
methods to measure the input-lag. However, I can now judge the input-lag
just by inspection. Simply move your mouse and estimate the elapsed
time until the pointer starts to move. Using my PS3Linux, I get a nearly
instantaneous feedback (around 20ms). Down at the PS3-GameOS the
value increases to an estimated value of 60ms by using the pad within
the browser! Subtracting the 20ms from my TN panel leaves around
40ms for the pad <-> PS3!!! wtf?

I guess, a wheel has an input-lag of around < 20ms. It would be worth
to measure this!!!

Why is the input-lag so important, anyways?
Well, if you want to react to something happening on the screen, then,
depending on the input device (pad) and the output device (panel),
the reaction you take kicks in (in my case) about 60ms later! Now
compute the distance one travels at a speed of 200km/h within 60ms.
Do it!

Controlling a car at/from high speeds is therefor very difficult, if you have
a large input-lag. Believe it or not, playing on a large LCD (with a pad) is a
clear disadvantage!

There is a workaround for hardcore gamers! Do it old-school! A CRT-TV
does not suffer from input-lag! Hence, 0ms delay from the output device.
A lot of hardcore gamers are playing on CRTs. However, a 1080p CRT
is rather difficult to find.

I bet that racing on a CRT, using a wheel, is physically the fastest/best
solution to nail down the fastest time in GT5P due to 0ms input-lag from
the CRT and only about < 20ms (I guess) input-lag from the wheel.


Using a large LCD and the sixaxis pad is the worst case scenario for playing
GT5P. I'm somewhere in the middle of all this mess. I can really feel the
60ms input-lag from my pad + panel (upon steering and acceleration)!!!
It's very difficult to counter act this. However, I will plug-in my old Sony
CRT on my PS3 within the next week to test it all out, to check out the
pad's input-lag, at least.

So, now you know what to do! :)

I have a lot more hints on how to improve the lap-times within GT5P
(including; using the pad right). But ... you know ... I don't can give
away all my secrets! I need to get into the Top-20, at least! :bowdown:
Hahaha ... yeah! Lets do it! :cheers:

For the sake of completeness; The input-lag of the DS3 controller
might have been improved, but I don't know.

Why do you make me angry by not considering all this before setting up this competition and by developing your game like this ?


The pad will always be an issue! Look at the things I've written above;
input-lag, resolution, etc.. It's much better to put the effort into a device
which is worth the effort! teH wheel! A high resolution and nearly
zero-input-lag pad would be nice, but it would be too expensive.

C'mon ... get over it.
 
I guess Clutch helps out Heal and toe technique :)

Yeah, though the main advantage (in outright lap time) in using the clutch on the G25 is the shifting speed, when the clutch is not enabled in the 350Z in GT5P does a kind of 'autoclutch' mode where shifting speeds are slower and delayed (as some have complained about). When I drive manual cars (in GT5P e.g 350Z) I always use the cluch and on ultra quick laps I quickshift or even flat shift sometimes which is much faster than when the game does the clutching. I think after a great lap of quick shifting using the clutch may make a small difference in the end compared to a DFP or other wheel.
 
Finally good lap with DFP: 1´21.203 --> 1st (FI) ;) ..I can still see a sub 1´21 with the DFP, but that´ll be it. At least with my skills... :lol:

FI:

2nd: 1´21.355
10th: 1´22.370
20th: 1´22.639

Don´t you just wish you were also living in Finland.. lol.

p.s. Thanks Sphinx for the video, made me realize a few things.. :)

@problemsolver:

Thank you for the feedback on my analysis...

You are absolutely right in (nearly) all your statements. What you describe is mostly the same as I have expierenced for myself.

I know about the input lag...
I know about CRTs having less input lag...
I know that input resolution is better with a wheel / pedals..
I know about the advantages of a wheel when it comes to sensitive steering..

But:

I am sure a good "pad" player would have a chance to compete against a "wheel" player if there wasnt the following disadvantages which are simply software related:

In doing a further research on these "disadvantages" and reading through all those replys to my complaint I now know that it is not only the clutch which gives an advantage to their users but its also the H-Shifters.

Let me explain:

Advantage No. 1 for wheel users without using the clutch but using the H-shifter / sequential shifter (compared to a pad):

(shifting goes 2nd - Neutral - 3rd)
Revalations do NOT drop inbetween shifting.
Next gear switches in at likely higher RPM.
Shifting time is less.

Result is simply an improved acceleration performance of the car.

Advantage No. 2 for wheel users using H-shifter / sequential shifter AND also the clutch:

Revalations raise up inbetween shifting.
Next gear switches in at still more RPM.

Result is an even more improved acceleration performance of the car.

Remember GT4: There were options for enhancing / tuning your car with such things like 3-Disc clutches which one could use for faster shifting and therewith enhancing your cars acceleration performance.

The use of these things were independent of the used controller.
They did improve your cars performance no matter if you were using a pad or wheel including clutch or H-shifter.

With GT5P one CAN improve the cars performance by using a different input device (controller). That is what for my understanding should NOT be the case.

Let one use a clutch / H-shifter or anything...
..but dont improve the cars performance by using this device.


If a non tuned 350Z will need 0.2 seconds to switch gears:
Let this specific car take 0.2 seconds to switch gears no matter what !


If a wheel / clutch user is able to assign the functionality of a clutch to his device: Let the pad user do the same ! (to a button for example..)

Arrrrghhhh..................


Problemsolver, could you please upload your replay of your 1'22:718 with the pad for studying ?

And Problemsolver....
You will never do a 1.21.xxx with your pad...
 
When you buy that faster G25 and use THE CLUTCH,let us know when your laptimes are even at the same level as using pad or DFP?During this summer of course.

I will never buy a wheel... my wife doesnt allow :-)

But I know that everyone has a long way to getting used to a wheel.
So you are right: It would take a long time to get to the actual level...
 
Minium, how is that G25 doing? ;)

Oh yes, my G25 is doing pretty well, and congratulations for your nice laptime with DFP.

I also downloaded yesterday that sphinx's ghost lap file, but i couldn't get it to function. Winzip says the file is invalid archive?...

So i'm still missing a decent (=fast enough) ghost file to improve my laptime. Battling with my own fastest ghost is damn hard. It would be easier if the ghost lap were a bit faster than my target time.

But i'm going to try yours tomorrow ;-)
 
@problemsolver:

It reads ProblemSolver. :odd: Thanx! ;)

Arrrrghhhh..................

"Arrrrghhhh..................", too!

Things will be sorted out once GT5 (GT5P-update?) is released, I expect.
And I strongly assume PD reads all the stuff written here!

Problemsolver, could you please upload your replay of your 1'22:718 with the pad for studying ?

Uhhh ... this would expose my pad "settings" ... I can't do this by now.
We germans do quite well on the leaderboard, and you know, every
tenth-of-a-second counts. ;) Well, I found a way to improve (?) on
acceleration control (in not loosing too much traction) which becomes
clearly visible from the replay. Using this technique I was able to get a
-0.5s on the bridge with respect to my current fastest time, i.e. 1'22:718.
And since I haven't managed it after the tunnel, there are some more
improvements to gain, to add up the time to ...

And Problemsolver....
You will never do a 1.21.xxx with your pad...

... 1.21.xxx? :eek:

However, I don't know if this technique really works out. But you can
have the replay once I've broken teH pad-barrier.

I really expect to lap a 1.21.xxx with the pad. I have a good feeling about
it, at least, since I haven't done a perfect lap with my settings, yet.

My next racing session starts on tuesday next week.
 
Just checked the UK rankings and I've been dropped into 4th place by another G25 user. :indiff:

I'll try and improve my time on the DFP over the next day or two and then compare my best DFP time with a good session using the G25 but without using the clutch. It should be interesting to see how they compare. 👍

I intend to, but it's important to remember that any results will only apply to me and my style of driving. Someone else could produce entirely different results, but it'll be interesting nonetheless.

Yes that would be interesting considering how ingrained this trial is by now:)
I would of thought it would be marginal without clutch. Also surprised sphinx that you haven't bought a G25 until now.

On Suzuka in spec I, I'd download the top time and see the advantage between shifts with people keeping their foot to the floor while quickly shifting with the clutch enabled and the flash of N Neutral in between and disengagement allowing higher revs.
 
I improved my time with the DFP :)

57,859
1.20,899
Regular 6th in Germany, the new toptime is a 1.20,399:bowdown:

Great DFP time. 👍

It prompted me to jump back in car and run again, and have now moved back up a couple of places to 2nd place (UK & Eire) with 2'21.108 (DFP) 👍
