Different physics.

[Lazy Liquid]

Throwing in my two cents worth, I think the difference in physics between on/offline is due to the bug people are experiencing with sudden losses of grip resulting in slower lap times while racing. (As detailed here: https://www.gtplanet.net/forum/showthread.php?t=237539)
The symptoms of the bug are almost identical to the 'differences' between on and offline, namely a loss of traction, poor acceleration/braking, resulting in more imprecise driving. So I'd say that it wasn't a bug, but more a fundamental flaw with the game that results in less traction the higher the latency.

There is not much info about how it works and witch condition it happens exactly. But this is not the first racing game online that i notice discussions about issues related to latency x car performance. Most of games call it "make up time" (MUT).

MUT happens when a game automaticaly try to fix someone´s performance with a bad upload rate, giving him an artificial compensation. Unfortunaly instead this car becomes faster or with best performance, the MUT tends to prejudice all the other racers, making they lose speed and grip randomly.

The most used pattern to understand this is: If your car is rocking on the track and the drifting partners who you are used to drift with are losing control like newbies, probably you are the problem. And if you are noticing weird and erratic physics, probably there is any rotten aple in the room affecting your game. And normaly, this rotten aple will be having his car behaving in a uncommon way (so its easy to notice who is affecting your gameplay).

For a final conclusion, is necessary to know if GT5 servers work centraly or peer 2 peer.

I drift with wheel and I would like to say that when i drift online/offline with the same comfort hard tires the track is MORE slippery online. It seems like drifting on ice and I have to adopt and adjust myself to new driving physics. It doesent depend on number of players in the room, even when I am alone on practice its all the same. I am talking about time trial with real grip offline and realgrip online. There is MORE difference if you choose drift run offline but I havent use it for a long time.

Mine didnt work at all, loss of grip and any preciseness

Weird dude, I tuned an S15 offline for Tsukuba and used it around a few other tracks online, only thing that felt different was that I could hold more angle online compared to offline.

Well, no smartassery here but they can be either setup online with one fixed host or people sharing the whole upload thing, it's in the online user manual

For me being a wheel user, before the patches I could feel slight differences, but now I barely feel any difference at all.

Yesterday I was drifting online on R246 trying to tandem. For one corner I was coming up to I could not stop sliding at all. I went straight into the wall. As did anyone else.

Did you test it only on other tracks? I tuned mine on trial mountain offline, and since i had so much practice on the track i did every entry the same, every time, so i noticed the loss of grip immidiately and loss of grip mostly = Also loss of preciseness since you cant estimate the cars trajectory anymore.

I tuned mine on Tsukuba, then drifted it on Tsukuba and felt near the same, went on SSR5 and I felt a little more slippery, hard to describe but yeah.

I very rarely play offline nowadays so it doesn't bother me, never really noticed it anyway, but I think online is actually more realistic because for example; Big jump tracks: Offline you will go flying into the sky and online it's a little more calm, more realistic you could say. That's just an example of why online physics are probably more realistic than offline.

So in real life you can only barrel roll through to 60 degrees?

30 degrees.

 

[Nismo34]

30 degrees.

Really? I didnt think it was that little...

I thought cars did backflips not barrel rolls.
