you realize this is heresy? They have piles of wood in the lobby for guys that say stuff like this..! :sly:

How are people supposed to accept this poorly executed game if they have to admit that the physics has issues? Don't take off their rose-colored glasses, that's just mean... :crazy:

I see. It does sound strange. Ill give it a try. If its as you say then its not accurate imho.

Another problem I think might be the physics is that when you hit someone in the back at a decent clip it automatically spins your car out either to left or right and you almost always end up pointing backwards. That ain't physics its wacked programming of the physics engine imho.

Also in any fast car if you just touch the grass with one wheel, without hitting the gas you spin out very often. Not realistic at all. I notice it especially with the FGT and X1. If you are not giving gas the car would just roll over the grass unless you had most of the tires on the grass at an angle. It wouldnt just spin right away as it does in the game.

To add to that it's a supercar so i'm guessing the flywheel is light (needs more rpm to engage without engine stalling) and torque at idle is very low for a car with that much power.

It's not 1963...

The Gallardo 560 has a very modern, 5.2 litre V10 engine that produces plenty of torque and plenty of power. We can thank the continual evolution of control systems for this. It's not much heavier than a normal passenger car, either, and they tank along all day.

So, yeah, it'll definitely chug along quite happily on the "anti-stall" squirts from the ECU. BMW's 2-litre turbo-Diesels drive against the brakes when they're tanking in top at 40 mph, and that has comparable torque at the bottom. :p


The possibility that the hill has nothing to do with it is very interesting, and makes me think I might have been on the right track after all! 💡

There is no sim that got the crashing physics right since it is rocket science. What games often do is exactly what you describe, a certain collision results the game spinning your car.
 
IRL i have a b3000 thats 5spd and if I slowly go through the gears on a straight i can get it to 50 km/h with out any throttle input.

and it can idle up small hills in second but it does have one heavy ass flywheel

Ditto, I hate 'gamers' who don't know jackall about cars playing GT5 and thinking they know it all about cars just because they jacked all of Stevie's cars and won all of Brucie's races in GTA IV :yuck:
 
Cars with an automatic transmissions do that. Try it out on any other automatic transmission car, like the GT-R or Evo X.

Erm.... all cars with a combustion-clutch-transmission drivetrain do that, read some physics books... good lord.

Wasnt complainging... theres enough other people to do that for me.

I didnt know they put an idle on the cars in GT5, im more than aware real cars do this, ive just never left a car running before, genreally racing y'know.

So your "flaw in the physics" is that the car behaves more like a real car than you thought it would ? LOL :dopey:

Yeah but then it should happen to the AI cars when they slam into you just as hard but it doesnt which leads me to believe that PD could remove that nonsense from affecting the player character. Such low budget programming shouldn't be in "the real driving simulator" lol. I think its laziness.

If they ever get to that, yeah right, I would hope they remove the idiotic program that makes every AI car in front of you move deliberately into your way for no reason other than blocking you. Its programmed. In RL you would be black flagged for doing that lap after lap as it happens in GT5. I did the A-Spec 200 laps of Indy Enduro a while back and man did it aggravate me to no end. Lap after lap after lap same foolishness ad nauseum.

Every single car does it. It's weird people don't know this.
It's the first thing I had to do when i started to learn how to drive: learn to slowly release the clutch.

However: even if they got this wrong... who cares? What's the importance of having this effect in a racing sim/game?
 
Here is a real flaw:

Grab any car, go sideways on a hill. Stop your car then accelerate A LITTLE. The car will SLIDE till 5 KPH then the grip goes all normal.
It's like the physics engine doesn't handle properly speed under 5KPH
 
Whats strange is not all cars do this in the game. If they are going to make it realistic and make the cars idle they should at least do it for all the cars and if I choose manual transmission the car shouldn't idle any more.
 
no. You people are just giving the OP a bad time. If the car was idling in gear, it would show a small increment in the Acceleration (White) Bar on the HUD. Like in the SLS and the Veyron and the California. But in the Lambo, that doesn't happen. Ok? It was just the momentum that kept it going! You people need a wake up call! >:(

Nope Idle is idle so no white gas bar because you don't add gas.

More like tires change after 5 km/h to less complex so do tires physic,

Very low speed physic is serious flaw in gt5. But it is so much better than GT5P low speed problem
 
There is only one car (as far as I'm aware of) with an Auto 'box that doesn't move while idling. Can anyone guess? Meh, I'll tell you; it's the Citroën C4! :D
 
So I was online at Top Gear test track playing car soccer and when I lined up against the tire wall on the north side of the track (on the runway) I accidentally trapped like two or three cones between me and the tire wall. But when I tried to apply the hand brake the cones kept pushing me forward. I want a patch!

If you take your car out in a parking lot, stick it in D and take your foot off the brake. Without any throttle input you'll accelerate. 👍

If you have a manual car, obviously you'll stall, but GT doesn't do this.
edit: I was simplifying, I have a manual Wrangler in the driveway. Thanks for the corrections on GTs clutch modeling though. However, lets avoid derailing the thread further.

Why will you stall in a manual? Lift clutch up slowly in 1st.mine roles about 5mph just on the clutch in real life and mine don't stall.

Id say given the extremely high idle speeds of alot of supercars (1200-2000) rpm, you might be very surprised :)

Not just supercars, when it's cold my 15yr old Oldsmobile can hit 50mph without touching the accelerator because the engine revs to warm up, I literally have to ride the brakes to go slower until the thermostat opens up.

This.
I've learnt that the hard way (in real life).
I crashed my stepfather's '39 Ford GPW into neighbour's fence because I had no knowlege about idle cars.
That was 4 years ago though.
