Steering input AC & real life

Whenever I make comparison videos I notice there is a often more input IRL than in AC. Even when I try to exaggerate my inputs to match the real thing.

What is the reason for this? Is it to do with the size of the wheel or something else. If it is to do with steering wheel size I think I would rather have roughly correct amount of input needed than correct turns lock to lock in a sim. Could it be just a mixture of RL driver being shaken around and more on edge? Could it be because my FFB is too low?

A few of the older cars like the 935 have steering that doesn't feel so direct but a lot of the cars I have compared there is a lot less input ingame than IRL, both in micro adjustments on the straights and adjustments and corrections mid corner.

I often delete my videos after a while but here are a few examples
(I was really trying to exaggerate my inputs to match the real car in the 918)

 

It's because you drive like a pussy, grow up and drive like a MAN! ;•)

 

One reason could be, that we would need super high quality wheels like strong and fast DD wheels. One driver said when you watch a GT3 driver he is not always making correction moves, its often just the forces coming through the wheel. But I am no expert, so this is no fact and just what I heard about. So feel free to correct this, I'm interested as well.

Point 2: Simulation software will always be just a simplified representation of reality limited by calculation power. Also the real world models from physicists like Newton or Einstein are just "simplified" models of the real thing for certain areas.

 

Too little required steering input would likely mean the optimum slip angles of the tires are too low (otherwise it would be the actual steering ratio being wrong).

Edit: and regarding the corrections, tires are incredibly complex, so in real life you'll always have more intricacy than in a sim. Coupled with a lack of G-Forces and some differences in the feedback of the steering wheel, this is probably the cause of the discrepancy.

 

Yeah, I've always kinda assumed that this is what is going on (partly because some of the input is insanely fast, fairly oscillatory, and in response to nothing that we can see), but you do wonder sometimes...

 

One AC video with A LOT of input.
Wheel Thrustmaster T150

 

I have the same feeling. I thought it had to do with the fact that my G27 allows a maximum of 900°, but obviously it isn't related to it (you have a T500 if I'm not mistaken).

 

When I watch good drivers driving, they are also so chill and smooth, when I drive then it is more like IRL

It is much down to skill of being able to plant down the car, if it is realistic IDK, but surely there are some kind of windows, which you, aliens, are able to find.

I have learned that wheel settings in combination has to do a lot. Do you use Gyro ?

Regarding the Ford GT40, you know it, that they race heavier GT40s and with skinnier tires than we have in AC, which makes them move more. Also it is always a bit oily, and sometimes also damp, also cement dusts and stuff... Also AC probably simulates cars in their theoretical best performance, IRL cars may have lots of unique little issues...

 

Could it even be all the feedback coming through our wheel that makes it not so necessary to use such input in game? You often see people sawing at the wheel IRL which I have never found myself doing ingame. < I mean entering or mid corner, off or partial throttle, I would do it when trying to exit the corner.

Yep the GT40 there is a different car, it's a "65 and no idea if stock but it feels like I'm not having to input as much as I would imagine is needed in a lot of cars. In pretty much all comparison videos I've made I'm not driving at the limit so if anything it is from under driving but I get the feeling I should have to use more input in quite a lot of cars.

 

I suppose you don't use gyro and damping maybe.

I use something like half damping both in profiler and in Gyro settings, makes it more natural.

If it is not that, then maybe it is fear which makes drivers to keep checking for grip or something, something psychological maybe. Maybe tracks has much more uneven grip than they does in simulators, even in dry conditions, oils and marbles....

Maybe it is something that @mclarenf1papa said, which is very likely. Or anything undiscovered/unsimulated yet.

The one thing that comes to my mid is fuel tank sloshing, IDK if that is an issue. But if the fuel tank is half full/empty then I suppose fuel acts much differently than solid objects experiencing G effects. And if it is sloshing from side to side, then it could possibly influence some weird CoG oscillation. But I am just brainstorming, cars probably has something against sloshing in their fuel tanks, and maybe ~50-60liters of fuel moving a bit wouldn't cause so much trouble for 800-1200kg car in particular situations. Yeah probably.. fuel tanks are chambered so effects are minimum... I have no idea...

Interesting subject, will have what to think about, read net and watch youtube lol




By seeing how many material is on this issue, I thought, that perhaps it is already simulated, because seems like essential thing.

 

Lot of wheel movement

 

If you record the live gameplay you will see much more wheel movement than a replay. RSS Formula 79

 

Can you record live gameplay with porsche 918 at laguna seca?

 

I wonder how other liquids affect the handling. Especially dry sump tanks, though wet sump is supposing to slush more, but maybe not ? Also dry sump is usually higher, I think.

Thats epic, this car has so much less downforce in slow curves lol. But this is powersliding/drifting... OP is more about quick little corrections, rather than big slide catches such as powerslides and drifting.

 

IIRC the 918 was recorded using 96% grip and trying to copy the real life steering especially a couple of notable corrections. A bad example really maybe I shouldn't have included it.

It could be something my end, I just wondered if other people had the same experience or if there was something else that could explain it.

 

Try to record a live gameplay. The replay is simplified. The realtime physics are much better ☺

 

Really ?

 

No.

(Well, it depends on the level of detail selected).

 

Yes sure. Test the difference. I have 2000 hours in ac.

 

On maximum detail the replay doesn't lose any fidelity compared to real time (and even on lower detail levels it's hard to notice much of a difference - it shows less detail per second so some of the finer details will be missed and the movements will seem less natural).
