Gran Turismo 6 general Physics Discussion(as well as video)

[dbarrade]

I usually drive no ABS and I found the GTR to be so unforgiving that I went to 1.

The Brake Balance in GT5 is broken, the higher you raise the value the more traction you get, so I am always quicker with 10 / 10. Even though the front to rear balance may be messed up, I make up for it elsewhere with the increase in traction. I mostly drive MR, so I am not sure if this is easy to feel in other drive-train layouts.

 

[TorqueHappenS08]

The GTR is incredibly twitchy under braking, Wish i could have driven the GT3 version, Also, the tires in general still need work, Kind of making it feel somewhat like GT5..

The tyres feel "exactly" like GT5!

The only difference i feel is suspension and i think that, along with aero, may be flawed.

The Z with the wing feels less grippy than the one without and i think its because the aero modelling is pushing down on the suspension giving it less travel, and the way PD have modelled the suspension it is then actually giving it less mechanical grip.

I don't know how it works in real life and unlike the framerate problems, it is easily changed.

I don't know though, i could be wrong and thsts how it works in reality?

 

[Fusion]

I think the tuned Z has harder spring rates than the standard one. This will mean less travel and less body roll, but the tires will break traction sooner because of this fact. On a near perfect surface (which Silverstone is) and with semi-slicks the harder spring rates would definitely be desirable, but it would depend on how you drive the car.

 

[Mad Matt]

No ABS seems more forgiving and therefore usable than GT5, in my opinion.

The hardest thing is that in a real car I can feel something through the brake pedal and I can feel the braking force as I and the car move forward. The changes in that force help me know if I'm skidding or not and I can adjust accordingly. I can also feel if I'm going straight or not. I don't think I use visual clues as much as just the sense of how the car's moving.

In the game I've got no pedal feedback for the brakes and no sense of forces being applied to the car. I noticed that GT6 is slower to lock up so I get more time to guess what's going on by sound feedback and looking at what the car's doing but for me it still doesn't translate well to real life. I wonder if they could give us some FFB hint that the wheels are locking........ That and some kind of pedal feel could be enough...... and of course getting the brake balance to be more realistic......

I think I'll go back to ABS 1 for now.

As an aside, has anyone else noticed that you can sometimes get away with flooring it even when you've got a wheel on the grass? I'm convinced I'm getting away with stuff that'd put me in a spin in real life..... I'll have to check my replays in a bit more detail.

 

[Dodzzz]

Do you guys notice, that in a slower car (the leaf), it feels like driving in slow motion?
the body roll... it rolls in slow motion.. oversteers in slow motion.. watch the replay!
Though the car runs slow, doesn't mean the body rolls also goes slow! right?

I compare it to the Z, it feels much more realistic, fast body rolls, fast oversteer, just like in a real car.

I notice this since GT2 actually.. (I haven't played GT1 before) that's why I always hate driving slow cars in GT2-GT5

and also notice how unrealisticly fast the redbull thingy in GT5 (forgot the name), it looks like watching at 2x speed.

I think GT is great at cars with 400-700HP range.. where it feels realistic.
I'm guessing they just use some sort of multiplier to define the speed of everything? (where 500HP car is set at 1x speed , and 250hp car is set to 0.5 speed, etc..)

How odd...a small econobox electric car on basic tires reacts differently than a sports car with sports tires on. Who would have predicted that? You realize the top speed of the Leaf is less than the highway speed limit right?

 

[ReverenceSatans]

What highways (apart from the obvious autobahns) have speed limits in excess of 90mph?

 

[Ills1999]

If you aren't doing 80mph on California Bay Area freeways, you'd better drive in your mirrors, no matter WHAT the posted speed limit is.

That pretty much goes for any big city in the US, the cops even go that fast, they have to or they would get run over like anyone else!

You don't understand my point..

Drop a 1000kg car with 500HP from 100 meters and drop a 1000kg car with 100HP from 100 meters and compare the result.
In GT, it almost looks like the 100HP car will fall slowly like a feather instead of a real 1000kg car.

It's not about the speed I'm talking about, but the body roll movements, the way the slower car "slowly" rolls back to position after turning in a corner, it looks like it's in slow motion compared to faster cars. almost feels like "moon" like.

 

[Lewis_Hamilton_]

But that's because the Leaf is slower at doing just about everything, it is not designed for quick direction changes like a sports car and the tires don't have that immediate grip, plus it has a higher ride height, therefore the body will roll more slowly, in the same way an old muscle car does compared to a low slung sports car.

You are also missing out on the suspension differences, one car is designed to absorb bumps and give a comfy ride, the other is designed for high cornering speeds which involves completely different spring rates, rebounds and so on.

 

[Dodzzz]

@Lewis_Hamilton_

I'm also not really sure..
but looking at slalom like this:



It's definitely much more responsive even though its running at low speed..
hmm maybe I'll try a slalom in GT6 to make sure...

Sorry, I was trying to be funny, not mocking I do get your point but I think it's a combination of the physics differences between the two cars as Lewis points out, and possibly the camera position on the Leaf. Camera position has a big effect on your perception of speed. The Silvia S15 is a good example of that. Not quite pulling it's weight at it's PP level, but it feels faster than other cars in it's class because the camera view is so much lower.

No doubt the Leaf is much softer with much more body roll than the Z in real life and the game, and much slower to respond as a result. I actually like the difference because it bodes well for having a completely different feel between cars in GT6. I don't want to drive a Fiat 500 and have it feel like a GT500 car is it did in GT5. The fact that you can feel and notice this dramatic difference I see as an improvement for GT6.

 

[THOMASBARNES]

I wonder how the new physics will affect the Ferrari Enzo just driven it around le mans in the rain and boy is it a handful under braking

Softer suspension, less stiffness in the tyres, higher centre of gravity? That can attribute to these feelings.

Gran Turismo has always been lacking in the effects of torque steer, and it appears the GTA demo is no different. If you take a RWD and perform a full-throttle burnout without any corrective steering, the car ought to spin to the left or right, but in GT it just sails forward making a smoke show.

I get the same feeling from looking at the Z, actually, although the Leaf does it more. You're not alone on this. 👍 It's rather subtle, but the body roll doesn't seem right. Just a little bit "slow-motion."

I knew what you meant and agree entirely.

The motion of the body is damped in a very similar way to gt5, except now the body moves a lot lot further. There is little or no rebound reaction. It's almost like no energy at all is stored in the springs, and the car returns to neutral from ridiculous roll angles far too calmly.

 

[TexasTyme214]

This. A good number of cars drove strange for no reason. The Enzo and R10, even with their long wheelbases, felt like limos in the turns. They weren't responsive enough for what they were.

That's what dampeners are for. Heck, the way to test if your shocks are shot is that your car pogos.

I have noticed that, only the leaf though, it is the worst. But nothing perfect.

The leaf feels like it's going to tip over, and no matter how hard i tried i could get it to 3 wheel into or out of a corner..

I have to say the body roll in the Leaf is extreme and I have to wonder if its just for demo purposes?

 

[Ills1999]

The leaf feels like every car I've had which had soft springs and little or no ARB, way more true to life than GT5

 

[TheeFrogmanlego]

I have a feeling the GT academy "demo" does not have the new tire physics.

 

[hillracing]

From my view having driven what they had at e3 I think this feels different than what they had there. Might just be my imagination but that felt better to me.

That's a great description of what I see, too. 👍

 

[05XR8]

im watching the making of the AM DB7 at the moment, that car rolls as much as the Leaf while they're testing it. so much air between tyre and fender and extensive lean. although, it is sliding just a bit as expected, the car looks planted and composed.

 

[TorqueHappenS08]

Anyone went to Goodwood and can comment on the newest demo? I noticed the grass physics are alot different than the GTA demo, in the most recent video, the GTR went into the grass sideways and the tires sort of dug in to the soil,caused the car to slightly make a tipping motion before resting on all fours, instead of skating on top of the grass like GTA. Definitely seems to be a big improvement. Like what we saw with the RX7 TC from the E3 trailer.

 

[fabio93bg]

yes, i' m interested in new feedback about physics from the googwood demo also. if someone went to the festival... please
