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

From Gran Turismo 5 to Gran Turismo 6, I really love the new physics engine. The weight transfer feeling is remarkable. I also really appreciate the graduate loss of grip as you feather the throttle at the ideal speed through a turn. Any slower and it's not the ideal speed. Any faster and the tire noise kicks up and the car understeers to the outside corner. I love how you can choose between the following to get back to the ideal line: back off the throttle, turn the steering wheel a little more (this only works to a point), or in a car with enough power, add more throttle to change the angle of the car. The videos of the stoppies seems a little unrealistic so hopefully that will be fixed with a patch. The rollover videos seem realistic to me though. Even a slight feint steering motion in a SUV can tip it over easily at high speeds. The AI feels much better too. I have been knocked off the track, spun out, and bumped from behind. Each time, the angle the AI hit my car and the subsequent reaction felt realistic. I just wish PD would focus on improving the sound both inside the car and during replays outside the car. Physics are amazing now and the car models (for new ones) are as amazing as ever.

I had the AW11 (figures) and it felt the same as my car. I have yet to experience snap oversteer irl though.

Yet to try an AW11. Will be good to see how they go.

A long time ago, I drove a 2002 Porsche Boxster in real life as a daily driver. On Pirelli P-Zeros on a cold day (tires not warmed up), the car exhibited snap oversteer if you were too aggressive with the steering (think sharp turning, not smooth inputs) while accelerating hard. Without a limited slip differential and driving aids, I would imagine a lot of mid-engine cars would behave this way. However, if the inputs are smooth, oversteer still snapped quickly (needing a fast reaction to recover)...it just didn't rotate the car as fast. This only occurred at slower speeds (say 30mph to 40mph). Are you playing GT6 with a wheel?

I have a G27 and my inputs are as smooth as I can do without being too slow. I can keep the car gripping but it ends up being quite slow. Maybe I am being too aggressive without knowing it. Better tyres didn't help much, neither did trying to tune out the oversteer with suspension.

Agreed. That's how it is driving in the real world. You can't just snap the steering in the real world. That's why the steering is more responsive this time around. When you play on a controller everything is pretty much on or off. It's either full throttle/ complete turns or nothing. They made it so you have to be more gentle, like real driving.

Plus mid engine cars are naturally trickier.... You have an engine behind you. Get the back end out and all of the weight of the rear plus the engine steps out.

One of the cars in the Goodwood Hillclimb events nearly torque steered me into the barrier a couple of times. Can't remember which one...RWD Merc I think.

Goodwood is all sorts of lumpy and uneven, though; that's why I head to SSRX. Tried the anniversary Cobra and GT40 and had the same results. Next, to check if lateral-g's are still identical for most cars based solely on tire selection.

Some of us have mastered gradual throttle brake, and steering with a DS3. :) Although I will admit I get lazy and just drift the corners sometimes. :D

Same as GT5, I found that out when I did the one-make GT86/BRZ race.

PD obviously didn't learn when they added the slipstream to be set to weak in online events...

Well they did in a patch that slightly brought it down in sensitivity and then I think they gave an option too in GT5 but can't fully remember at this point.
 
I can't make a video to show this off to everyone, but I want everyone to at least try this. In GT6, I've just tried out the Corvette C7 and Ghia Roadster with Comfort and Sports tires, along with SRF set off and traction control set at 0. There was actual torque steer in both cars. You probably can't do this with Racing tires due to its increase of grip, but with comfort and sports tires you actually can.

Try it on a track that has a straight a way, let's say Bathurst and equip Comfort Softs and Sports Hards. You'll see what I mean, it's really cool that there's torque steer in GT6!
 
Regarding drafting, it's as bad as it was at GT5 launch, you can get ridiculous ammounts of speed by drafting, you can keep with cars that are much faster if you catch the draft properly, especially noticeable on tracks with long straights, like the back straight at Bathurst.

I noticed the AI catching and passing me in a car simular to mine (both Subaru Impreza) and wondered... hmm his car has more power. What actually happened was that he was drafting me down the straight, it's really strong.
 
As great as gt6 physics are, the ****ing habits i learn from gt5 are literally driving me mad, I can't ****ing unlearn them. I may quit the game for a week already. e.g. im constantly making mistakes that I won't make in gt5. Its **** being 16 and not even driven a car for real around a track yet, Dunno what its like.

Could it just be the rubber banding??

You can't chalk AI behaviour up to drafting. Depending on what car you choose they sometimes are just a lot faster on the straights. I have been entering events way down in PP and a tire grade or two down and getting destroyed on the straights but it isn't the draft, it's just the cars.

Whoever uploaded these videos. With such a stiff suspension on the Ring and still using curbs on every turn what does he expect???

All these videos seemed legit to me. Instead of jumping the gun calling it "Bad physics" some people should consider working on their driving line. Maybe watch some more videos of real life racing?

Yet I understand it might be hard for many using a DS3, its not easy to be so sensitiv on the input as you should be. Agressiv wheel users also have a problem now, it worked for GT5 but not really for GT6 anymore. The difference is hughe and PDI did a great job (on the physics).

It's not just the AI that has a massive draft advantage though, I've used the draft at bathurst to catch and pass cars with a big power advantage, when I couldn't even stand a chance while driving infront or side by side them. Draft is extremely strong in GT6.

I'm talking about driving 20mph+ faster down the straight than I would normally.
 
Hey, posted this in the tuning forum, just wanted to mention I think I figured out the brake bias issue. When I added the brake kit to the car, The bias settings started producing the correct response finally. Give it a try.
The down side is that we can use brake bias to help an untuned car when doing 'tuning prohibited' racing.
 
Draft in SP seems the same as in GT5.

Based on a quick LMP/Silverstone test with a buddy online, it is quite reasonable on "low". Furthermore, aero push is quite noticeable with high DF cars such as the 908.

As a side note, the straight line speed as a function of wing setting also seems improved. Got a 30kmh difference in max speed with min/max settings in a GT3 R8.
 
This is the actually world record, do you think physic at this level is full of tricks? You think the driver use handbrake?

it's a replay from the first driver in the world rank!

The event isn't over yet. Damn If I had to list all the hotlap leaderboards I've been top of only to be slaughtered by 5 drivers in the last hour of the event, claiming a "world record" in a simulation game is a pretty cringeworthy thing to do.
 
YEAH BABY!

It happened on its own, nobody bumped into him. AI braking on Route 246 on the 8th corner.

How much power does that Quattro have? Seems incredibly slow to me - struggling to get 120mph out of the thing...
 
I have not available gt6,
but I wonder how the car behaves after the jump, as the car lands, how works, soft suspension, for a normal road car. Or how it will look on energy suspension rally car, the bus or VW.
I have not found any video jump car gt6, on a springboard in the Eiger Nordwand in the editor or trails.
it would be interesting to see it in Slow Motion and compared to gt5

I like how the cars hold there line when drive around turns. We can pick a line and adjust better with the throttle by lifting off.
