With this lastest patch, driving a low hp rwd is really much more simple. You will spin just if you rape the throttle and steering.

Low-powered RWD cars are fine, but high-powered ones are uncontrollable speed caskets without TCS or race tires. The Carrera GT, for example, is a mess at low speed with TCS off, even on the best street tires. And that car has 325 width rears.
 
Was driving an E46 M3 with 414hp and 2400lb with no downforce. No weight on rear tires mean less grip. Oversteers can be caught when the car kicks out by a long shot. Feels more natural. You can still bin it if you are not careful, but the key is I don’t have to drive delicate to carry the car around the track and has a bigger window to stay on edge.

what are you classing as low powered? the m4 425bhp/580 odd pp is fine with just abs for me.
 
The problem is they only have a tyre model for hard race tyres it seems. The other tyres are just tweaks of this tyre model to turn down grip, so it doesn't scale well and is shoddy.
The cars behave nothing like real life cars on comfort or street tyre. Man just take "the real driving simulator" off the box and we are good...
At this point now this game is just useless for anyone remotely serious about racing.

I disagree. Most of the physics are an improvement, but the low-speed tire physics, which has always been a problem in Gran Turismo, is still pretty terrible. It might even be worse than the previous games.

This is compounded by the fact that it’s very difficult to modulate throttle on a powerful RWD car. The throttle seems to be 100% open even though there is still plenty of trigger travel left. Not to mention that the adaptive triggers do a poor job of indicating grip. They should increase resistance just before tires lose grip to let you know you’re on the edge.

I’m a big GT fan, but I’m pretty unhappy with the current state of things (not to mention microtransactions). It’s very difficult to drive even a moderately powerful RWD car without TCS. You end up doing giant burnouts everywhere or spinning.

Wait, are you playing with a controller? What trigger are you talking about?

I couldn't care less if the game is improved playing with a controller. Because with a wheel it is a total disaster compared to GTS. The FF is dead, vague, barely any feedback, the cars even low power 4WD and FF cars are prone to snap oversteer, it is not an improvement in any way shape or form.
 
Please compare the Lambo in ACC in Barcelona and the track experience Lambo in Barcelona in GT7 and tell me there's nothing wrong.

I've just spent the last two hours in AMS2 with the Porsche 911 RSR and BMW 2002 Turbo, and I have to say, as much as GT7 has improved over GTS, those two in AMS2 highlight the gap that PD still have to fill in terms of both physics and FFB.

The BMW 2002 in particular, as its a car that you can't go full throttle on until your straight or as near as damn it, as the risk of the turbo coming on boost and throwing you into a tank slapper is significant. However, the tyre model and suspension feedback via the FFB is on another level, in particular, the feel of tyre flex is absurdly well communicated, and as such its easier to understand exactly what the car is doing, where the balance is, etc.

Anyone who has AMS2, give the following combination a go for a comparison.

BMW 2002 @ Brands Hatch
Real Weather set for 8/10/2019 @ 12 O'clock, you should have light cloud and a moist track surface.

Are you using custom FFB or Default/Default+ in AMS2?
 
For me personally all I can say is that the driving in GT7 feels absolutely amazing.
It’s very natural and to me the driving experience is fantastic. I mean, I’m no Physics Scientist but I drive Cars and Motorcycles for almost 25 Years in real life and to me this Game has without a doubt earned calling itself ”The real Driving Simulator” 😁
Kaz, you‘re a Genius and I completely feel your Philosophy behind the GT Series.
This Game is awesome. I‘m out… 😎

I disagree it is not a disaster with a wheel, and to me the FFB is way better than using my GT DD Pro on GT Sport.

I disagree is not an argument. So you do not see that all cars are so tail happy as if you were driving a sled on snow? Or you don't care about that, or you drive with assists on where it doesn't really matter?

I know that some cars are tail happy but l would not say that the wheel is the issue here, it's more like the physics is the problem. I don't have any problems with 4WD and FF cars in the game, and I use TCS 1 on road cars that are RWD cars 🙂.

Even with max aero and weight reduction and sports soft tyres RWD cars handle like ass, it's so bad it's not even funny.
But to me the biggest telltale sign that something is seriously wrong with the physics in GT7 is that if you accelerate out of the same corner in a higher gear you'll loose grip much easier. When it should be the exact opposite.
 
I personally think the physics is quite accurate.

Have you ever driven on a track with street/comfort tyres in real life ?

Yeah, using a controller. By triggers, I mean the R2 and L2 triggers. I had no idea the game had issues with a wheel though. I actually assumed that it was tuned more towards using a wheel, but I guess I was wrong. Yikes.

Just checked and I'm using the rFuktor 5.0.1.3 custom FFB file.

Here we discuss the custom FFB files, share settings for various wheel bases & iterate to improve what we have. ---- Custom ffb file installation...

Alright, was just curious as I am using the rfuktor FFB as well.

I feel compared to the Default setup it really makes a gigantic difference, sadly we will never have the possibility to have users tune and maybe unlock the FFB in GT7.

What makes you think it is accurate?

A Track usually has rougher asphalt than the street so it should have more grip than any street. What's common in many of the cars I've driven, even RWD ones is that none of them would just try to kill me when I put my foot down at 80mph, you'd need 600+hp for it to just blow off the tyres at that speed. Especially to have it blow off the tyres easier in gear 4 than in gear 3, well that just defies known physics.
 
Hey uh... Is the C4 ZR-1 supposed to be better than the Ford GT 2016? Both are heavily modified and the C4 doesn't even have it's largest wing (The cool pedastal wing is the one I'm using) and it's beating my Ford GT times on Willow Springs by over a second, and currently, just to beat that C4's time. I have to "push" the car and struggle.

Something seems weird with MR cars entirely, it doesn't help either that there's no feel to the slip.
 
Big unproven controller theory below, possible human error

Is anyone noticing the auto counter steering assist/ auto centering, working in the background for controllers? (Sports Hards is what I've been running since the game came out for baseline)

I've noticed it since the game came out, but haven't been able to put words to it properly. It's noticable when the car's already slipping nasty torwards big drift territory, it fights to try and recenter the wheel while I'm countersteering already.

Easiest replication I can get is driving backwards and trying to gradually turn, and watching the wheel fight itself to hold dead center.

At speed, if I try using power induced oversteer I have to keep it throttle planted and countersteer heavy to maintain a small amount of slip or be thrown off into the shadow realm. The ability to smoothly countersteer and roll back on the throttle is out the window right now.

I thought it was me, and that I might have been losing my mind. 😂😂 Even 7 sensitivity it feels like my steering's being filtered heavy. The higher the speed the more it's being filtered vs GT Sport where the steering stays linear, and stays sensitive even at speed.

Closest thing I can think of is suspension caster, or it's the physics and I suck 💀

GT has always filtered controls and aids. I am not sure how exactly in GT7 but GTS has counter steering assist and stabilization. GT7 looks better but they won't remove something worked for many years.

I found it incredibly noticeable when I briefly tried the controller. It’s like two different games.

I'm not using any aids, besides ABS on default. I never plan on it, but there's CSA going on in the background for controllers even while it's off.

I have half the amount of fine control in terms of steering input VS GTsport. I know they've always had filtered controls but it feels like they turned up the filtering 50%, threw the linear steering in the trash and added a bigger deadzone. Essentially, it's like knock off Forza lmao

I wish they did something like F1 2021 with the ability to make a controller profile yourself

It's possible. I play two types of games. Normal sims like R3E or AC without aids and then more casual ones like Horizon or GT. In casual ones you need to play their game because you are not in a full control, you need to learn their system. It's not much satisfying but I find GT7 very good because of physics. GTS is very casual. In GT7 everything feels so slow, that could be maybe what you don't like. Horizon is much faster.

Yes, settings for controllers are very important. PC3 is dead to me because default settings are terrible.

Well... I would say the physics are good, definitely a step up from Sport post-(credit nerf)patch. Racing the Supra MkIII (A80) which I owned is very similar to what I felt with my real life ride, God rest her metallic soul. Of course "feel" is entirely subjective in a video game, and I'm beginning to feel the nudge to buy that darn Fanatec DD wheel at $700-ish, yikes! But there is an extra 10% or so that racing sims do better / more accurate, as a number of folk here have tried to explain, sometimes with a bit too much jalapeno. I fully expect more physics patches to come, but as it stands now it's good for some really fun racing.
 
The more I've driven GT7 the more I've narrowed in on what I think the two main 'issues' with the physics are. There's definitely a lot that's improved and it can behave very realistically in a lot of ways, but there are two things I think are hampering things at the moment...

1. Tyre model
The tyre model has consistently been a weak spot in GT games since the racing game market started leaning back towards higher simulation as a popular design feature. It still seems comparatively simplistic and the flaws are being highlighted by the improvements in other areas.
2. Steering linearity/ratio
I've seen more people talking about this which gives me some confidence that there's something to it. Steering linearity seems to be... well, non-linear. It's beginning to seem like it's on a multiplier of some kind depending on speed, which is why the faster race cars from the Gr3 upwards can feel so tight in the wheel, and seem to have far shorter steering ratios at high speeds than at low.
