GT5 Physics - Spec 2.0

[HJLamont]

I just did nurburgring 4 hr to give the physics a real run. I used the S2000 GT1. The car seems to have more grip than before and tire wear has been significantly improved. I can do 5-6 laps now before a change as opposed to 2-3 before. Old tires also have more grip. Having tires near death is no longer suicide.

 

[CodeRedR51]

Whereabouts?

Just cant see it on their official site

Mentioned by KY before the Spec 2.0 release, but somehow absent from the official press release.

The tires are different.. I used to be able to do burnouts with the stock Opel Speedster (Comfort Soft) and now you can but the tires grip much quicker... from 22,000 drift laps to barely being able to drift with it stock.. I literally have to change the tires or increase the power to be able to do what I used to before. With that said, I like it because I suppose it's more realistic feeling.. like there's actually traction with the road, at the same time I need to reteach myself how grippy the tires are.. I think they increased the road friction though instead of the tires - because I know the walls are a lot more frictional too. Feels a lot like the older gen GT games - it's better this way but they should have released it like that :\ oh well.

Done 7'07 tonight. Will get pics up along with vid soon.

Yes thats a nice time but it was done with sport soft tyres, the car comes with sport hard. Which is the tyres used by Timppaq.

Spinning tires didn't have enough grip before.
It was next to impossible to replicate real world FF 0-60mph times, so if they added more grip like this, they did well.

But from everything I've read and tested so far, still no time improvement for any car/track combo, I'd have to say the cars that will shave significant time will likely be MR/RR - harder to drive because of over-steer types of cars.
Rather than an actual grip gain, it's a driveability gain.

 

[MrGrado]

I think they have added "tire squishiness" There is a large increase in overall grip (with racing hard tires offline anyway), slides are easier to control, braking is improved and control of a car with a slight brake lockup is improved. Cars that would break into oversteer easily before will remain neutral more. Cars accelerate better from low speed corners while wheel spinning than they did previously. There is also a bounce sensation now if you put a wheel over a ripple strip. Tires also seem to be able to absorb a sharp load now without causing loss of control like down shifting, maybe for bumps, aggressive initial braking and standing starts too.

I seem to be able to detect small changes to suspension settings now too. The settings might change the performance of the cars differently now or the cars just have a better feel to them now, I'm not sure yet.

Edit: oh yeah and my times are lower. I'm 1.5 seconds faster at Suzuka with my DB9 tune and that is mashing and thrashing with a dual shock controller. My previous best time was done with wheel and I was really on it, It was a pretty hot lap, so real performance gain might be 2+ seconds.

My DB9 is 1500kg, ~530PP ~470HP and 49 / 51 weight distribution. So if lap times aren't consistently faster for everyone, there might be some pattern based on cars weight or some other characteristic.

 

[supersquirrel]

yessss i feel the bouncy and body roll. me gusta. 👍

 

[KoAStR]

I think suspensions gain more negative camber than before the patch when compressed/under load, at least visually. Try checking this out in replay-photo mode.

Nice observation. A good testament to a well done suspension re-model if that's true 👍 I will check it out.

 

[Coxis]

Well, I just had a quick go and although I can't break it down as fancy as you guys can, I did notice a few differences... the biggest being that slides are easier to catch, and feel more realistic. Is this true or is it the placebo effect?

R1600Turbo, what settings are you using for your DFGT? Force setting, power steering, etc.

 

[another_jakhole]

It's all true. All of it. It seriously is.

 

[parabulla]

The feedback feels more progressive to me, more organic and not as jagged as before.

 

[NEPALII]

I have just tried drifting with clutch. Before Spec 2.0, I couldnt even drive with the clutch(probably due to lack of support of G25 or the old physics engine wasnt good with the clutch). Anyways, besides being able to now race with the clutch and be quick, I can now drift, not so good though, and with the clutch. It also seems that the pedal sensitivity has improved which is important in drifting. GT5 with a few more tweaks could match the PC sims. Love the tire load indicator as well, very useful!!

 

[Frozzy]

I have a G27 and I personally don't feel any clutch difference. It's still very touchy.
Drifting with the G27 does feel a lot different. I can now let go of the wheel and let it countersteer on it's own.
Without tracing the wheel at all.

I wont be getting back to my PS3 for a few days, has anyone played with the suspension tuning to see if it works properly now? I've always felt this was due to the poor gt5 tire model in regards to weight vs. grip. I would also see this in lots of different situations, such as FR car pushing more as I let off the gas. Getting the tire non linearity of grip vs. weight correct is critical for tuning to work properly, and for getting the car balance to change properly as you vary the weight front to rear. For me this has always been the most painfully incorrect thing about driving in gt5 vs real life.

I played with suspension tuning again for a bit after the updated. Unfortunately, some of the settings, or at least the result of the settings, still seem to be reversed from real-life applications. For me this makes tuning a car's suspension in GT5 a grueling trial-and-error affair, as I'll probably never be able to reconcile the errors and I'm always forgetting which settings work as they should and which ones are backwards. (For example, in order to make the Yellowbird oversteer a bit less for online racing, I had to significantly stiffen the rear of the car. This is a complete reversal of what happens in real life. Since I own a Porsche with a similar chassis and an adjustable rear sway-bar, it took me probably and extra hour figure out what was going wrong with my Yellowbird becasue I had to do the reverse of what I do in my real car. How PD can do some things so well, with such an eye towards detail, and then screw up other things like this one so badly? I just don't understand it.)

R1600Turbo, what settings are you using for your DFGT? Force setting, power steering, etc.

No power steering, feedback on 8.

 

[Astro-Racer]

The FGT is soooo much nicer to drive now. It's probably the car that has benefited most from Spec II. With improved physics and a fairly decent cockpit view.

My test was done using the Lexus LFA, oil changed & fully broken in, otherwise completely stock. (Sport Hard Tyres)

Done 7'07 tonight. Will get pics up along with vid soon.

Spot the difference. That said, I do believe there's a lot more time still to take so 7'09 should be within reason easily 👍 With, SH's I may add. If you do it before me, post the replay here please

Yes, I question some of the claims made on here about the physics. I simply dont believe the update has made the huge improvement that some seem to believe it has made. Its open to discussion... Is it not?

Thanks

For my part (you did quote me afterall) you questoned my feelings / impressions. That's different.. OP asked:

What does everyone think of the new physics?

That's the question I answered. There's certain difference between giving one's feelings / impressions and putting it out as facts.

 

[bcruise]

How about the crash and rollover physics?

I managed to pull this one off with my Viper - I'd never even rolled a car in this game before, much less done this:



Hello Rollover trophy (and then some). 👍 Of course there should be nothing left of that car...oh how I wish you could actually do serious damage to them.

 

[tribolik]

ABS 0 feels different, a little more loose and lock ups are more prone and uneven.

Really??? it does feel diferent now... because before I had to move the brake balance foward so that the back end wouldnt snap and now it seems that the cars brake more with the front tires like IRL with a brake balance neutral (5/5)l

I like to play without ABS not because Im very good at it but because its more enjoyable... and true to RL (most race cars dont have ABS)

 

[CSLACR]

One thing I did notice is with a stock Jaguar from the "recommended cars" on Daytona RC, changing BB to 5/6 really made the rear come out more, I had to put it back to 5/5 for a good balance entering turn 1. (Private lobby, practice and race.)

I brought my FFB down from previous 10 to 6 now, feels about the same as it did before on 10, so I know that got stronger in some way.

 

[DAIR]

Yes thats a nice time but it was done with sport soft tyres, the car comes with sport hard. Which is the tyres used by Timppaq.

Then I shall take to the track with those tyres.

Good luck sir.

What are we trying to prove with this again? (I missed it in the fuddle of bickering)

As said ill take to track using the hard boots. Love a bit of friendly competition .

Again, I'm questioning the claims being made. This is a debate so it does relate to the OP's thread.

 

[DAIR]

Lol not sure now.

I question physics.... Then went on to say I could do sub 7.10.000 track time in lfa... Which I done but using wrong tyres.... Errrr so its turned into a sort of competition.

In all seriousness though any changes to the physics couldn't have been that great... They wernt even worth mentioning on the main website.

 

[amar212]

Lift-off and suspension travel has been drastically improved, I concur.

I have tested my basically tuned Enzo for LeSarthe Festa Cavallino Seasonal and there is no way I can win the race now - I used the same car I was winning with prior to S2.0 -because of the overall effects that physics are displaying now.

Body roll, weight transfer, braking and suspension management have been remade in full. And it is beautiful.

Care to post up details of your cars settings?

It hasn't turned into a competition, you just claimed

I can get 7'09 in the LFA with the same tyes and no mods.

And some people wanted to see it happen 👍 You brought it up on yourself, even though this whole sidespin of how fast laptimes are possible is irrelevant, the only thing that mattered about the laptimes I noted, was that they were similar pre & after spec 2.

In all seriousness though any changes to the physics couldn't have been that great... They wernt even worth mentioning on the main website.

It's your opinion and you're fully entitled to it 👍 This is what the thread is about

Again, please post the replay as an attachment if you get that '09.xxx 👍 Would like to drive against your ghost.

Yes.... I claimed I could get that time. Others asked to see it. Only gave people what they asked for.

Soon as I'm free I shall post a vid.

No settings, I never touch settings on my road cars nor install adjustable parts.

It has oil change, installed fixed suspension kit (no altering, default installed only) and maybe a Race Chip (I think, not sure) for 707HP bower-boost (I am sure it has 707HP but not sure is it gained only with Oil Change, can't check now since I am not at home).

Tires are Sports Soft because I needed SS in order to catch the leading Enzo prior to the Spec2 update. No assists except for ABS1.
