Any good?
full
It sure was! :lol: I got all the hilarity out of my system and saved a couple of replays last night.
RIP memes.

At least what people have produced will be treasured memories.
Well said. This has to be one of the best threads in GTPlanet history. :lol:
 
Anyone got the cars to jump again since the hotfix? Surprised at the speed of that hotfix for something that wasnt a big deal unless you tuned that on purpose :lol:

Looks like anything that is visually damaging to the image of gt7 gets fixed first. Seeing bouncy cars in twitter feeds mightve had something to do with pds haste :P

It's hard to tell for certain, but the thing that looks so weird about these is that it kind of looks like the car is still turning to some extent even with the front wheels in the air, as though they are still exerting some lateral force despite not touching the ground. At the very least the nose appears oddly straight where I'd expect it to step outwards more than it does. It makes it look like the outer back wheel is accelerating really hard to keep the car more or less straight. There's certainly a reduction in turning force but it doesn't look matched to the situation.

But it's hard to tell if I'm seeing that right or if there happens to be no lateral force on the car when the front wheels leave the ground.
 
I don´t know if anyone already told this, but, in some cars with swaped engines, the rear tires are losing traction and bumping as soon as it acelerates.
for example, the GR YARIS and the GR TOYOTA COROLLA, with 2ZJ engine. It looks like you drive in gravel and bumping roads all the time.
WITHOUT the engine swap, it is normal.
 
Hello friends,

After a lot of questioning and testing between custom races and lobbies since one year, I really have the feeling that the physics aren't the same between the two. In custom races, I really have the impression of having more grip while being faster than in lobbies. My tests are done with the same car, the same race conditions, tyres.. etc..etc., and with a single opponent.

When I switch from one to the other, I really feel a difference in driving. So I was wondering if you too had experienced this difference?

I take part in championships organized by a League in Europe. Since then, I've been training in customs races with the bots to simulate what I should expect with Settings from the official lobby, and when the real race day comes around, every time I've felt a marked difference in grip, speed and increased over/understeering (depending on the car), enough to require me to adapt my driving style in the first few laps.

So I told myself that probably in custom racing, the physics are simplified to suit the driving style (skills? performance?) of the bots, whereas in lobby racing, the physics are more complex, adapted to competition between humans?

+1.
In my case, I mainly participated in private races organized by a friend, and even when I recreated the room settings he told me about, it felt like the cars handling were completely different in SP and MP.

Of course, behind this is probably the psychological frustration of other players who are faster than me, and the resulting unconscious roughness in my machine controls...

I guess theyre using the same physics ideology as GT5/6. Single player has a more sophisticated and developed physics model while online is more simplified. Obviously the gap between both isn't as big as GT5/6 when you couldn't even roll a car over online but you probably understand. Maybe it was never supposed to be this way but they had to dumb down the physics model for PS4 players? We'll never know since Polyphony is less transparent than my company's HR department.

You actually still can't roll online in GT7!
 
I’m not quite sure their reasoning behind the AI being glued to the track. It’s like their car weighs 10,000lbs. You cannot budge them, if you go in hot, you bounce off of them. Pretty lame. This game is so good and yet so bad in some areas. I struggle to have fun in single player. I’ll start a single player race, I’m having fun, and then the AI start blocking and brake checking mid corner, pit maneuvering me coming out of corners. Like we’re exiting a right hand corner, I’m keeping it tucked in on the inside, we have another right coming up down the straight and you move into me? And they have the audacity to take away a clean race bonus with those AI actions too.

Strong points of GT7… livery editing, better exhaust sounds than previous releases, graphics, online with friends is great, proper handling compared to previous versions like GT5 and GT6, that’s all that really comes to mind for me. Scapes is kind of cool too.

Thought we would have had more tracks, more weather dynamics for all tracks, tune sharing, car gifting and surely more realistic AI by now. I remember GT Legends (like in 2004?) having better AI than what we’ve got. 20 years apart between these two games and were left with huge concrete blocks moving around the track for AI with a car skin.
 
Why is this PP system so buggered that when you try to improve a road car in performance like either an engine swap or adding permanent improvements like cams or bore up will award you with the dreaded PP⚠️ warning? As you have just spent credits on something you cannot change back without buying a new car, you are buggered with a car you cannot drive in ANY race!
I had read a post about an engine swap on a C4 vette running on the WTC700 at Le Mans and when I tried to replicate same with a swap I was fubar with an unusable car, I was gobsmacked and forced to sell it off and buy another and try something different. As I was in the parts place I chose one item at a time and checking for the PP⚠️ before purchasing and discovered with race tyres the warning will most likely pop up if my PP will exceed 700, as I noticed in example my PP was about 685 or so, I picked the race camshaft and there is the ⚠️, not buying it i try something else like stroke up and I see the buggered ⚠️.
So I have a car that is limited in what I can do, yes I can do more if I switch to Sport tyres but then I cannot race in some places unless I have race tyres and that will make the PP⚠️ appear.
I have had some success in dropping my power via the ECU & power reduction but that makes an underpowered car .
Looking for answers here and hoping someone has improved methods of dealing with the ⚠️. Thank you.

I had the old Shelby mustang and a corvette (c4) that gave the PP ⚠️

Found if I just swapped racing transmission with full customizable transmission that gave me my car back. The other was suspension but I’d rather the transmission than suspension.
 
I do hope they fix the physics, it's getting really annoying trying to do hotlaps and this happens:


To be fair, you can't just put slicks on a car with stock suspension or it will indeed do insane things like bottom the suspension out.
 
Well I tried the Mercedes SLS not long after and about a minute in it speared off to the left into a barrier with no prior warning, and that's a car you'd expect to be capable with slicks.

The same thing happens with other tire compounds. Regardless, in some instances the suspension starts bouncing erratically, and it’s just too otherworldly for a simulator. The bug also exposes how poorly gravity works in GT7.

Not really? Semi slicks, sure, but not full slicks. The SLS is a GT car, not a supercar IIRC.

I was doing a sophy race at the Ring last night with a BMW M2 on SM tires and it was doing some weird stuff. No Endos but mid corner it was like I was being rear ended without a car in sight. Only once or twice but definitely all jacked up.

Was it quite early on before that big corner to the right with the bridge? Where it dips.
 
I believe it happened there. I will try again this evening or over the weekend and see if I can replicate. 👍


Ah no worries. Realised after if you go to 1:15 onwards, you'll see me making a correction where I had the same trouble.

Seems like when the suspension hits the bump stops is when it's happening. Big concussive bumps? I'll play more. I love that M2 so much on those tires. It's great fun.
