GT5 Physics - Spec 2.0

[Coxis]

No power steering, feedback on 8.

Thanks. 👍

Sorry but I'm not sure whats to be laughed at . I chose the wrong set of tyres and done the lap in 7mins 7 seconds! Roughly three seconds faster than the time he posted in Hard tyres.

Sport Soft tires are actually 15-20 seconds faster than Sport Hard tires on Nordschleife. "Roughly three seconds" with tires that gives an improvement of almost 20 seconds to me don't seem so impressive.

Anyway, I tested various road cars with Sport Hard tires, and by now the two cars that are a lot slower than before to me are the McLaren F1 and the Ferrari Enzo. Maybe is just me that have to get used to the new physics, but with other cars (Ferrari 458 Italia, 430 Scuderia) I'm just as fast as before the update. If anyone of you are testing stock cars on sport hard tires and compare with pre-update lap times, please share, I'm curious what results are you obtaining 👍

 

[diegorborges]

I already checked. No chance with normal (stock) tires. There's always some load under on the rear inside tire under steady cornering conditions.

I achieved something like that with Sports Softs tho... Golf MKI @ Nordschleife... stiff suspension... but like you said, isn't normal tires...

 

[mr_VOLCANO]

As crazy as it may sound, if you want to spot the differences in "balance" and "flow" of the suspensions, take a lap in the X2010....

Or go to Eiger, and do the seasonal drift event. The differences in "dirt" tracks is amazing.

The change is subtle, but that how PD works. I still think that you need a wheel to feel it properly. I´m driving with an DFGT.

My wheel is broken, so only tested 2.0 with a pad, but still a huge difference. Much easyer to control car and suspension reacts more real to elevation changes and bumps, Its actually fun with pad now

Just to add my impression of the new physics. Drove 300km grand valley in new GTR then did some laps in FGT then completed compact seasonal in Audi tts, NSX 91 then motul z in super gt. In short, drove a lot today generally with sports hard, tried a few in sports soft and racing soft (tire change during endurance alternately) and tried srf off then on (Tokyo bay just to compare). I find it is lot easier to catch a slide as I was unable to drive NSX on sh without srf or asm prior to update. The transition from grip to slide is slower and smoother. Srf felt a lot more abrupt (able to feel when it suddenly kicks in) now that slides are more controlled. The tire bounce over curbs causes less force feedback on g27 but the short term loss of steering control more prolonged after the bounce. For FGT, driving it felt foreign suddenly as I've only recently completed the FGT championship and drove Indy 500km 1 day prior to spec 2.
So definitely fairly drastic changes in the physics. As for AI, I noticed during my race a NSX do fishtailing and drifting thru the corners during grand valley enduro. Not sure if that's the norm. Also my tires seems to lose grip even when the wear is not severe. As such, my best laps are achieved in 2nd or 3rd lap of grand valley after each tire change.

Initial impression: Not a fan of the new physics. I use a DFGT. Dry grip appears to be more arcade like with it easier to kick out the rear end and keep it there.

Wet grip is probably more realistic but the lack of force feedback makes it impossible to figure out what the car is doing. Racing le Sarthe with 100% rain saturation while on full rain tires was impossible to stay on the track and drive at the limit. My car was spinning in circles, ending up in sand traps, spinning drive wheels, and clipping corners...and I'm usually very precise in the rain but I could not get a handle on the car. After a 15 lap race I maybe got one good lap in...but that was after the track had dropped to 75% rain saturation.

----------------------------- # -------------- %
Love it! -------------------- 349 ------------ 71.37%

Were better before 2.0 ------ 28 ------------ 5.73%

Looks like a landslide.

Everyone (almost) is saying that the changes are small. Of course they are small! The game physics are alot like driving. Look at the difference in the Time Trials. The difference between first and 100th place are tiny, but there are 98 people between them.

 

[NLxAROSA]

Everyone (almost) is saying that the changes are small.

If you are referring to lap times: yes, small changes. But the changes PD made in the physics model are huge. I can totally understand that this took a year (not so much the changes itself but the tweaking and tuning to make sure laptimes, cornering speeds, etc. etc. still match up) to complete. So to me, the changes are huge, and they are putting GT5 right up there with the PC sims as far as realism/depth is concerned. 👍

Also, the difference in time between 1st and 100th in a TT leaderboard may be small, but the difference in the skill that is required to make that happen is huge. Still a valid analogy though.

Ha ha...

GT5 has broken the laws of physics. Just noticed time travel damage.

10 laps of beating a car up. In replay, if you jump straight to the end, car remains in mint condition. Watch the replay though, so the damage builds up, then jump back to the very beginning. All the damage carries over.

So the lights turn green and your car is already mullered...

The AI physics seem to have changed a little.

I've never seen an AI car lose control on it's own and spin till the update. Today I was doing the British Seasonal at Cote De Azur and was bearing down on an Elise. I was giving him a little pressure and the soft left into the hard right down the hill. The AI went wide on the left overcorrected into the right and around he went. Pretty cool, first time I've seen the AI do something I've done countless time.

I've even tried to P.I.T. the AI before while they were driving a Yellow Bird and couldn't get them to go around......

 

[notStig]

So far I'm liking the new phisics. It seems that it's a bit easier to spin after being hit in the back (did it to the leading car in FGT seasonals after he did it to me) and roll over (happened twice while racing NASCAR in Daytona after being spun out by the AI wich has never happened to me before at least in this track).

The Yellowbird usually lost it on the second to last corner in the 4 hrs Nurburgring race. Could be it occurs more often now.

 

[Johnnypenso]

Still, FF hot hatchbacks with normal tires (comfort soft, or sports hard tires at most) don't lift their inside rear wheel when cornering hard. The suspension model in GT5 has probably been improved in a very general way, but key characteristics of certain cars aren't correctly reproduced yet.

Real life example:

Praiano posted a pic in his garage today I believe of an FF car lifting the rear wheel, cornering, not on the curb. Peugot maybe, can't remember...check it out...was at the end of his garage thread this morning.

Did you roll over after crashing into a wall or did the car just flip when going sideways?

 

[Johnnypenso]

Could have been a fluke but had a spot race last night around 550pp and I started 2nd. Guy in first was in an FF Honda Civic Type R and he actually beat me into the first corner. I was in a McLaren MP4. Never had that happen before.

No, using racing soft tires has nothing to do with what I meant.
The car in that pic is lifting both wheels on one of its sides, as if it were about to roll over. I've seen that often, using racing tires, that is.
Lifting wheels with comfort soft tires (= summer performance tires, in GT5) just by cornering (without hitting obstacles) in GT5 doesn't appear to be possible. Cars that in RL clearly do that, stock, don't behave that way in the game.

I think this is closely related to the fact that with normal tires (comfort soft/sports hard) it's essentially impossible to roll over a car in GT5, whereas in real life... [look at my avatar for an example].

I rolled an X2010 doing the Vettel at Nurb GP, is that new? (Certainly new for me)

One thing that bugged me about GT5 was the Sebastien Loeb Chamonix event. I retried this last night and couldn't get a clean lap in after 5 tries (I did gold it previously). I tried the same track with the same car with real loss of grip in practice mode and got a time some 40s faster than gold. Why are they so much different? Did Loeb think that slipperier was more realistic and everything else is dumbed down? Did Loeb just happen to "visit" Chamonix when it was icier? 40s is a long long time.

I just did this right before the update, guess I could try it again, but I have to assume you screwed something up in your testing, no offense.

With grip reduction on "low", I can turn under 3:30 on Chamonix with the C4, in the Loeb challenge, (grip is set to "real" there) I turn between 4:00 and 4:10. (Probably 4:00 with a few runs)
So I have to say I think I know where your 40 second loss comes in already.
And I did all those runs before the update, with shown 35-40 second difference.

I'd like someone to comment on the drafting. The weak draft seems to be a lot better especially when cars are more spread out but I'm not sure when cars are grouped together such as the start of a race at DSS. I tried a race at DSS with some friends. Standing start, I started in second but I had a good start so soon got into first but before the end of lap 1 everyone behind me came flying past so I was quickly near the end of the pack. I don't know if this is realistic or not but the draft seemed awfully powerful. Has anyone who is familiar with oval racing tried it out in spec 2?

It's less then "strong" for certain, how much less is debatable.
"Strong" is the same as before Spec II.

Just ran it again with grip reduction on real with a standing start and got 3:32 then switched grip reduction to low and got 3:31. So it appears that the grip reduction setting does nothing.

Edit: checked out toscana. times were much more similar to Loeb event and changing grip reduction had no effect.

 

[notStig]

Did you roll over after crashing into a wall or did the car just flip when going sideways?

The car flipped after the AI hit me and made me crash in the wall. The car did a whole flip. The second time surprised me because I hit the wall with the rear of my car (didn't seemed that hard) and the car simply rolled. Sadly I think that going sideways very fast still won't make you roll over.

 

[Astro-Racer]

Sadly I think that going sideways very fast still won't make you roll over.

It's even harder now. Even with the special suspension tunes.

I always used to do this for fun:



Now it's impossible. The car lifts on to two wheels slightly, but there is an invisible force stopping it from rolling over (Offline).

It's goofy, but it was fun having a few cars tuned just to play around with like that

 

[notStig]

LOL That video is pure awsome!!👍

hahaha it's all mostly ridiculous. Did I see a few sparks crashing into grass?

GT5 Best Buy demo had a lot of sparks, PD toned that down big time. I don't think they should have toned it way down for all cars, especially not the old ones. For the newer cars would be right.

 

[Timppaq]

An extra 5-10bhp has never made that much of a difference in this game (to me)!

"that much" yeah, well I guess that depends.

So you'll try to run the 7:09.xxx without BREAKING IN the the motor then? 👍 Interesting to hear that, because actually I do believe breaking in the motor is not needed to get a '09 - you just need a really good lap, so I guess it doesn't matter. Good luck, waiting for the replay.

Better yet do it with a worn out engine (without an oil chance) - oh sorry I forgot its a game and the engines in a game dont worn out...

 

[Timppaq]

That's obvious. No difference there.. (lol)

Well, you're doing something wrong..

SRF for one and not the other?
In any case, if you can run within 5-10 seconds of my times you'll get gold in the challenge no problem. 👍

And I did mine without SRF.

 

[Slash]

Well these new physics are good I'd say. At least karts don't spin out as easy.

 

[another_jakhole]

Is this serious? Not trying to come at you, but cars lose and gain power in GT5. Isn't that what wearing out and breaking in an engine is?

Well these new physics are good I'd say. At least karts don't spin out as easy.

I just tried the Ferrari Seasonal at Sarthe for the first time since the physics improvement, before the first turn I could already tell the difference. After the first two turns, I started to wonder (racing softs, I only grind that event) how people don't notice any difference. Granted, not everyone has a steering wheel, but even with that first turn, I had to adjust. Noticeably, the bumps are so perfect (not literally).
