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

So how do the new physics go against those of Forza 4?

Similar but it still has flaws (as done F4 of course). I also doubt their claim this is a BRAND NEW physics engine, it just feels like an updated version of the previous engine. I don't think you would build a new physics engine from scratch and still not have things like torque steer properly modeled.
 
That gif reminds me of this:

Someone was asking about why guys in the top of the leaderboard so far are all gunning it into corners, drifting and getting fast times, when in real life it wouldn't be effective.

I explained it as it being due to something that's not only lacking in GT's tire model, but most every tire model in any game or sim. Just one of those things that seems to be the last frontier in simulating cars properly that allows people to drive cars unrealistically past the rubber's limits.

There's really no engine bog. You have all that load on the wheels, when you try to get them spinning again, it's just too much for the engine. Or that's the way it should be.

Still no torque steer?

What about drifting? I always felt I could drift around a whole track in Forza, while GT seems really hard to hold anything sideways for any real amount of time.
 
No torque steer, no. Couldn't tell you about drifting, I don't do it.

Neither do I to be honest, Im more talking about trying to save over-steer under acceleration while exiting a corner. In Forza I could get it under control, or hold a nice, controlled slide, pouring smoke out the back. In GT, in the same situation, I feel the over-steer coming, quickly counter steer and hope that I save it (usually a 50/50 deal).
 
Maybe we shouldn't have understeer or oversteer either. They're both a pain in real life and slower.

I see your point. To me torque steer is more of a flaw, understeer/oversteer are typical characteristics of all cars, to a degree. I guess this is just my dislike for FWDs talking, so I'll go away now.

Whatever your opinion of torque steer is Gran Turismo is trying to be a "Real Driving Simulator", you can't be that if you aren't simulating certain aspects of real driving physics.

Not having torque steer takes away a lot of the challenge of launching a high powered car as well as not simulating it in high powered FWD cars. A Shelby Cobra does not launch in a straight line at full throttle with no steering input in real life but it does in GT5 and seemingly it will in GT6.
 
You can spin the front wheels on the Leaf - and do a "burnout" - Yay!

There is torque steer, if the car is under load or the track is uneven, not when pointed straight ahead on a flat surface. If GT6 had more surface fidelity it would be more obvious

The way the cars rise on the haunches on launches looks great!

I'll put some video up in a bit
 
Anyone think we're running the new suspension model on the old tire model? That's what I'm getting from the demo right now.

I can get the Leaf to slide by playing with the throttle only, and that's a massive improvement from FWD, but the Z doesn't have me convinced. Over bumps, or other times when the suspension needs to act quickly I can feel a difference, but outside of that it feels a bit too much like GT5.
 
So how do the new physics go against those of Forza 4?

Forza is still leading. But before I commit to that, I want to try the two back to back. GT's hope right now is the suspension model, but I think it's being overshadowed by the tire model.

If I'm right, and the tire model in use is actually the old one, that could be good news. If the tire model improves as much as the suspension, GT could easily become the better of the pair in terms of car dynamics.

It has nothing to do with FWD, actually. Any situation where one wheel ends up spinning faster than the other ought to affect the car accordingly, whether it's FWD, RWD, or even AWD.

Interesting. Uneven surfaces never had that effect in GT4, or GT5 from the times I played. Will a RWD car start to slip its tail downhill if you launch from a banked spot?
 
I've only done the Sunday and Clubman events so far as my girlfriend had been around all day, and only used the DS3 pad so far.

As there's no option to change the controller sensitivity (as far as I could find), this demo seems extremely twitchy to me, even the R2 and L2 buttons for accel/decel seem overly sensitive, perhaps that's just me.

The frame rate is also terrible for me, it's very inconsistent and therefore off putting. The graphics do look nicer however.

My overall feeling is that there just seems to be too much grip, I've purposely been trying to over drive the car and never lost control, just a bit of a drift in the 350Z. The replay I watched didn't look realistic at all during these moments, especially for something on sports hard tyres, but the suspension movement has definitely been improved.

Perhaps my favourite thing about the demo over GT5 is not the sound (it's the same), graphics or physics, but the presentation of the menus and loading screens, and the improved loading times. I'll try the game further before making any final judgements (and I understand this is only a demo), but so far I feel that overall GT5's physics are better, how much of this is related to the steering/button sensitivity I don't know.

There's option for change controller sensitivity under Skid Recovery Force for you.

Thanks, didn't scroll my eyes that far down, just switched everything to off or 0 straight away apart from ABS, as I haven't seen an option for an RA menu. I'll go try -2 out now as that's what I use in GT5.

Well, GT6 have different UI than old UI in GT5 which cause some users confusion.
 
Do tracks have bumps now? Haven't tried the demo yet.

Layout improvement on susuka?

Yes, but it's nothing drastic. I've only noticed in a few specific spots. However it also makes me feel that GT6's suspension model indeed beats out Forza 4's. Forza has a superior tire model though. The dynamic grip was immediately apparent while at the same time, Silverstone feels bland on Forza because it's ultra flat (or the suspension hides everything).

Unfortunately though, until it's confirmed whether or not the demo is using the new tire model, it's hard to make a call on GT6.

Remember this is the demo, they might not be completed yet.
 
Personally, i don't understand, why they didn't fixed the clutch problem. I should release gas pedal to shift gears and this is ridiculous. I mean seriously, any person who drive a car should notice that all the time.

Also i'm pretty dissapointed by the fact, that fastest lap is still done sliding around every corner. That's easy to see in replays of best lap holders - guys are literally go sideways, overheating their tires every time, in every corner and that is a best possible way to make a good time. Ask any racer, he will prove, that drifting on asphalt road is just a mistake.

And sadly i really doubt that's about to be fixed in full version, since all problems existed in GT5 all the time.

I can get the 370z to rotate under brakes, something I could never do in GT5
 
Turning off the ABS makes a big difference, ABS to 1 changes things too much considering that is the lowest setting...

The changes actually make throwing the Leaf around quite fun, something that GT5 would not be able to do.

A video I made abusing the cars and physics :)

Seems like the smoke which are produce blocky around the car unnoticeable anymore. Nice.
