Gran Turismo 7 Physics

[Tommy_D]

They didn't make the change for specific wheels, they fixed a specific characteristic of the vibration oscillation calculation. Everything else feels the same (if not a fraction lighter) so up the in game torque 1 or 2

The rest is all exactly the same, in that you can if you want dial in the feel with the in game FFB sensitivity just without really gruff feedback patches.

Curbs are harder again, slip is slightly muted.

I'm not sure any of the updated FFB stuff affected belt or gear driven wheels I'm pretty sure it was done for DD wheels as it was a very specific issue.

No, they changed the settings specifically to the T300RS. It is in the patch notes:

2. Controllers
　- Fixed an issue wherein the force feedback vibration effect would be different on each side for steering controllers such as the THRUSTMASTER® T300RS;
　- Lowered the output of the THRUSTMASTER® T300RS by 10% to reduce motor strain;
　- Lowered the vibration effect of the THRUSTMASTER® T300RS and Fanatec® GT DD Pro/Extreme.

I have my FFB settings at MAX value (10) and the wheel is numb relative to what it was just 2 days ago when I only needed it set to 7. The things they say the "fixed" with the T300RS were not issues that needed to be fixed. The FFB was not different on each side of the wheel (whatever that means) and the motor strain issue was easily fixed by having the user dial down their FFB settings in the game's settings. If you were to poll all the T300RS users on this site and asked them if they can't turn down the FFB settings any lower to reduce motor strain, no one would say they have that issue. I was running mine at a 7 for street cars and dialed it back to 5 or 6 for high downforce cars. Still plenty of room to turn it down and reduce motor strain if necessary. Now I'm running it at a 10 for street cars and there is barely any weight to the steering. High downforce cars I can run at 10 and they feel okay but they changed the vibration feel on it as well, because I guess they needed to change that too??? So, the wheel is weaker with its FFB and the vibrations/feel has been reduced because let's add insult to injury.

This is a really weird one because I think we are all right, yet wrong/disagree at the same time.

Every car I've owned has had power steering except the 3 205gtis I had. Not one any of the 27 cars I've owned (mostly hot or performance cars) have had over aggressive judder when over turning the wheel and inducing understeer (mostly deliberately)

Any time front or back loses traction there has always been a lightening sensation because the tire has lost grip so the mass moves with little friction. Take a donut or drifting you don't get a weird judder on the throttle?

That said I feel like we still aren't quite there yet feel wise to suit all tastes, the changes seem squarely at fixing the the oscillation calculation for front end slip which has worked mostly but for some I can feel that seems like a regression.

Off the bat it sounds as if most of your grip loss has occurred while accelerating whereas mine tends to be evasive. I will readily agree that if she’s stepping out under gas there rarely is any judder. However, if a deer jumps out on a narrow country road with high embankments, and you snap the wheel to avoid it…as long as you don’t roll it! 😂 ..reacquisition can be a bit violent. Most of my roads don’t really have escape valves so you have to wrestle things back within narrow tolerances which probably leads too experiencing some of the more violent variations of grip loss/reacq. Also, some of this comes from power sliding the old explorer into my parking space, from about 50mph(hard pack dirt driveway) for the better part of a decade. You don’t get the violent judder every time but there are a distinct set of tolerances and situations where you do. My muscle memory is built around it and the pre event sensations

Fwiw. With the exception of my first car at 17 an early 90’s prelude, and present ride which is a 19outback, all my cars have been rear wheel drive, but not sporty. At all. 😂. Trucks, econoliners, explorers, transits, nv1500’s, hino’s, sterlings, izuzu’s, fords. The big trucks were all big front wheel and duely’s in the back. Full they hauled 15k lbs ish. So yeah. The complete opposite side of big torque. That said, i was always hopping in a different vehicle so always drove by feel. Think thats why i get so ragey wah pants when they bork things. Ill try to log in tomorrow and see if messing with the sensi or something helps but last nite wasn’t as upsetting as it was depressing

I have my FFB settings at MAX value (10) and the wheel is numb relative to what it was just 2 days ago when I only needed it set to 7.

So reading the fix, they fixed a difference with feedback being inconsistent between left and right movement on the 300, knocked the torque back 10% and fixed the vibration issue in DD wheels.

I'm not seeing a lot of crazy changes there to affect most of the driving experience.

For reference I run a 8NM DD wheel at on the wheel 110% but in game 5-7 such is the difference in physical torque. My TGT2 I'd run at 8-10 and even then it could feel a bit weak.

I did not stay within the bounds of grip. Haha.

I was stopping from 60mph, I left two super long blackies avoiding a semi that decided it needed an exit ramp at the very very last second, they signalled for a split second and took that lane. I had to brake like a madman, and try to veer out of the way because I was beside them when they made their decision.

The wheel in my car didn’t vibrate hardly at all, no power steering either in that car, MacPherson Strut… it simply went very light! Lots of tire squealing.

As for GT7, I don’t think it was accurate, I’d be cruising around a corner, mid turn, everything is fine, suddenly brap, brrrr until you lift throttle and countersteer. It felt like an on off switch. Idk maybe it’s just me but I don’t think it’s a realistic feeling at all. I didn’t feel any gradient, anything I experienced was bang its on. I drive fairly smooth imo too.

Im on the dd extreme, what are you using?

My grip loss is apex turning in aggressively more deliberately to get angle to exit. Not driving wide, you've watched a few of my clips I'd imagine?

I've mostly driven performance cars or hot cars on track with occasional low level race cars so can't comment on larger stuff of surface stuff.

And yet the game feels like crap relative to just 2 days ago. No amount of settings adjustments I make to my wheel will give me back the feel it had just 2 days ago. As I've stated before, there was nothing wrong with the T300RS wheel that needed to be fixed but PD took it upon themselves to make changes to all T300RS users. They could have, instead, made a change to the in-game settings menu under the T300RS wheel settings to give the users the ability to adjust this stuff themselves. But no, they just hard wired these changes in to the game's settings and said, "deal with it".

If you sit back, take a breath what has actually changed for you in tangible terms.

For me:

Shaft rattle shake has gone
Weaker torque generally
Curbs are a bit dicey in RWD cars because you can't feel the slip/unloading as much so you have to be super early to catch it

These are my main actual driving observations

Everyone's mileage varies with these things but I honestly don't think the changes are particularly drastic just muted a couple of things to fix a bigger problem.

They haven't radically changed the game or physics or even settings just dialled it back a couple of notches.

I dont need to take a breath. The wheel is numb. I don't know how to explain it to you in any simpler terms.

Imagine that you could feel the road and what tires were doing on that road, then an update comes out and you can no longer feel the road or what the tires are doing. You go to your wheel settings in the menu and turn it up to maximum then retest. A bit of the weight has come back into the wheel, but everything is still much lighter than before the update. You go around a turn and where you had good feedback just 2 days ago, you now cannot feel what is happening with the tires. They are clearly slipping because the car is understeering through the turn but you can't tell if there is more grip to be had of if you turn any more that they will completely go out. So you turn more and the car is still understeering but you are getting no response from the wheel that the tires have lost their grip completely.

The wheel is numb. Plain and simple. No amount of wheel setting adjustments can bring back the feel the wheel had just 2 days ago before this update.

Edit: At least there is still a little bit of weight to the wheel. Update 1.49 got rid of all the weight and the feel. 1.55 fixed all the problems. 1.56 took all the feel away and halved the weight.

Im on the dd extreme, what are you using?

Logitech G Pro. IMO the tire scrub effect felt like somebody turned a light switch on, and there’s tire scrub. Somebody mentioned going to willow springs or another track with a long wide curve to feel it come on slowly, it doesn’t or didn’t (haven’t tried new update yet) it just turned on, wheel goes light, then tightens up and vibrates. Like I said, first impression was what the heck is wrong with my wheel. Didn’t feel natural at all.

Ya. Wish you were closer. I could take you out and make that outback chatter in a matter of minutes. Lots of sharp elevation changes and corkscrews make it easy…also..i need new tires and don’t care atm 😂

That might be part of it. Your cars have been nice. Mine beaters..or i just didn’t care because it would be a beater soon. The joys of owning a wholesale seafood company. Everything gets ruined sooner, than later. So screw it, and have some fun 😆 but yeah. My wanton disregard for the health of the vehicle’s(its all coming out of me arse anyway) likely comes into play..a lil..

That said, this is about finding speed a d momentum at the edge of grip and now the illustrative sensations are gone within the game. Well, not gone, but the paltry brap feels more like im cornering on old asphalt eroded by a winters snow and sand, and now cracking a bit, more than tires scrubbing.

As it stands now, the game in vr no longer triggers the muscle memory i was using in irl yesterday to fling a car through a few corners.

@hawkeyez ahh. The extreme had a nice gradient where i could balance grip and velocity.
