Update 1.06 possible changes to the physics + general physics discussion.

[cjr3559]

The old MR Lambos seen very planted from what I recall in the semi-distant past on the 'Ring. I always run stock with no assists, and the stock SH's seem to have more grip. They used to be more twitchy and eager to go for an off-road excursion if I got too cocky. Lately the Bulls seem much tamer especially compared to their FR Stallion competitors of the same era (especially the GTO '84).

All in for gravity change, more gravity added to game.

Yes, you may be right. I noticed interesting thing yesterday when racing on Nordschleife. There is one (well, not only one..) corner, where if you drive over its high curb it is very possible to end up driving on 2 outsideside wheels or even flip over. I was little surprised to see that it didn't happened this time. Before this update this corner was like part of the lunar rover mission, where it was very easy to flip over. I'm going to test it more today to see if it's really due to higher gravity, or simply my car has suspension setup which prevents such accidents. Also I am curious about wheelies under braking, is it still possible?

 

[FussyFez]

Now this increased gravity seems plausible.

Bone stock M3 CSL on SS would easily roll If I clipped the kerb at the top of 'foxhole' before the patch. It does seem more resistant to getting airborne...

Not had a chance to try the MR's yet.

As far as I'm concerned there's a new setting in suspension tune called placebo.
I believe this is what most of you are experiencing.

 

[RedBaron]

Compared testing on Eiger Nordwand / Cape Ring jumps in both versions would easily solve the "placebo gravity" question.

Few meters longer jump on 1.05, plus higher than on 1.06. (from 28sec)

 

[Morphisor]

Huh, I really had NOT felt any change so far. But after seeing these reports on gravity, I went and tried to replicate a few of the 'high kerb lift-off' moments I had recorded a few months ago. Used the exact same cars, and it proved to be impossible.

So I say, you guys are correct. Gravity has indeed become stronger. And this is a good thing!

 

[YZF]

Just to let you know: no changes in physics which affect lap times.

Did some stable/on the limit comparison runs and lap times are basically the same.

Speeds for both cars at takeoff please. Thanks.

Nope, apparently not. We've been definitively proven wrong by this post:

^Hard to argue with that concrete evidence.

Perhaps we should all note whether we're noticing differences offline or online. I only drive online so that's where I'm noticing the changes. Not sure if they can be noticed offline or not.

It's not synced because it wasn't important, landing was synced but there was a different speed at the start line. I have few laps recorded with 1.05 as fast as i could but I don't know if there is any reason to check physics based on that.

 

[LVracerGT]

Not trying to be mean, but that video proves nothing. The speed from takeoff could have been different, and when I slowed down the video and looked at the shadows for reference, it looked like the 1.06 jump was a tad longer.

I stated already in another thread I felt no difference in physics, but I think it would be worth re-visiting the roll over/center of gravity issue. It's possible this is what was updated and what people are feeling.

 

[racefan88]

There was definitely something changed in the physics. I was testing for a race on Motegi oval pre 1.06, and had my setup running low 34.4s. Post 1.06 i couldn't do less than a high 34.7 with the same setup. I had to make some changes with the setup to get back to low 34.4s. So something definitely changed, sorry I didn't really look at what changes I needed to make, but essentially the car had a lot more understeer post 1.06.

 

[OdeFinn]

@LVracerGT, @GTPorsche, @eSZee, no problemo, I have 1.05 on fatty and 1.06 on slim, when back home I'll do some replays.

So smoke gets pixelated again ala GT5, wow that's pathetic, meh, carry on with the physics debate.

I'll be free later tonight if you need some help 👍

 

[Jimmy_Pop]

My MR cars feel more stable when pushed, thus allowing me to run faster. Also very minor suspension spring rate adjustments make more of an impact on the handling.

I use a wheel, so I am able to feel many changes through it.

 

[Moon_k]

The GT-R's feels more
aggressive than before when you enter in the corner and when you are on the exit it is easyer to control it since the update 1.06

 

[Master__Shake_]

The video showing comparisons of 1.05 & 1.06 tire smoke doesn't show evidence of gravity changes. The Evo in the 1.05 segment was shown at higher speed than the 1.06, which is why it went higher in the air and longer distance. If gravity was indeed increased, cars would no longer wheelie or do so at much less distance - which is not the case.

1.05 had changes in tire physics, most notably comfort hard tires, but I believe 1.06 is a placebo effect for the fixes of framerate and game stability. If you want to test the theory yourself, revert to 1.00 then find a map with a significant jump and compare it at identical speeds for 1.00 vs. 1.06. If you haven't updated to 1.06 yet, then you could compare to 1.05.

Has anyone speculated that perhaps they changed the UNTUNED behavior of some cars to better reflect their real-world handling characteristics that you would expect to see if you drove one off the dealer's lot? However, if you tune them, then you get the tuned behavior you got before?

I also tend to think that the change is more noticeable in stock cars. If you've added/tweaked parts on the car it might water-down any noticeable change that was made to the physics since you've essentially tuned any unique characteristics out of the car. Take a stock MR car out, on stock tires, and see if it's easy to drive or still a bit of a handfull like they were the first few months of the game.

However, a few of the recent posts are reporting they noticed a difference in tuned cars as well, so it might not be a sound theory.

 

[Ridox2JZGTE]

I was driving my Audi R8 LMS Ultra Phoenix, it was tuned back in 1.04 and I drove it at 1.05, already has over 1500km on the clock. I didn't notice any changes immediately, still the same too much front grip bias, twitchy in low speed. Then I started to tune it from a clean slate, using my experience and learned knowledge from building 458 GT3 and Camaro GT3 replicas, now the R8 LMS Ultra Phoenix drives better than ever. I noticed that any value changes to ARB, spring rate, damper comp and extension have a great impact on the car, and can be felt. This was already in 1.05, when I built 458 GT3 and Camaro GT3, but seems to be more pronounced now, should I say more responsive suspension and chassis physics ?

 

[BrandonW77]

^ If Ridox says something has changed, then something has changed. He knows the intimate details of the cars and game more than the majority. And this shows that tuned cars have been effected as well. IMO whatever changed is for the better and I think it feels the best it ever has. Now just leave it alone, please, PD?!


Hi Rido.

Hi Rido.

Oh, hi I will post the new Audi R8 LMS Ultra Phoenix within 12 hours, maybe you might be interested to give it a try, it's quicker than my older tune, still on the same spec, 599PP, 528HP, no oil change and it beats my lap time on Z4 GT3 and SLS AMG GT3 at Bathurst and Brands Hatch GP with more PP.

You can try to drive one of the cars that you often tune/race in 1.05, make a simple changes, increase ARB by 1 or 2, or lower damper extension, you should notice the difference quickly

 

[NixxxoN]

after playing for somet time with the latest update, I dont recall noticing any changes on the cars I mostly use, which are about 20-30

I will wait with impatience. Mine has more than 7000km now, about 50 changes (also used your initial tune), still hard to drive really fast, but still my favourite car.
I should mention I drive it almost exclusively in the Nürburg 24' race.
I even bought a second one now, which I left stock and this time I will not stiffen the chassis. I feel that could have been a serious mistake...

Did not really feel a difference after 1.06...

I rolled an RGT at Flugplatz by clipping the curb on the first part of the right-hander there.

I can't see how gravity can be wrong, to be honest, it's a static force. What may have changed is some damping or lever curves or something on specific cars, but there isn't really any way to say that gravity has changed. Another possibility is a change in downforce.

The floaty physics when the car is on its roof is because all the sophisticated parts of the physics model operate through the tyre contact patches only. The actual free-body simulation is poor, and always has been.

Incidentally, the RGT felt about as stable as it always has (dangerous on the brakes, great neutral or under power), but that's RR. Just keep testing, I spose.

Online or offline? It could be possible that the changes are only felt online. I do a lot of driving but never do any driving offline so I wouldn't know how it felt before or after 1.06. But I know what I feel now is different.

 

[t3kc0h]

What a bizarre statement. Just because it's not as good as PS2 means there hasn't been any improvement from the rubbish that it was before? If it was averaging 40-45fps before and it's now averaging 50-55fps that still qualifies as an improvement. That's like saying this $50 bill is worthless because it doesn't have the same value as a $100 bill.

Anything over 30FPS isn't noticeable to the human eye so....

But I have noticed the front end of my car doesn't like to grip as much. I don't know if anyone else feels this, but I feel it in the wheel.

Higher frame rate can improve the feel and handling of the car, and low frame rate can impair it. I didn't say anything about the visual element. But when I play F1 2013, which is capped at 30fps, it certainly looks/feels different than GT5 or GT6. 👍
