LFS is the result of a passionate small team.

And this is perceived in every aspect.

Physics stand out.
Cars behave differently. You can feel that.
Sound is synthesized and this is GOOD.
Force feedback is not gamish but near reality.
And the list can go on for ever

It is not a game, but it can be used also as a game !

So a good way to express lfs in your video, should contain the message

"Save your lives, learn to drive, in a simulator"

Greetings

We are lucky, that Mr. Scawen's personality has the tendency to create "art" in whatever he is in "love" with.

But please remember (sure you do) that perfection costs in time and soul stamina as learned in the hard way, via the new physics engine.

To share your art with lucky one's (us), please find whenever possible the golden analogy between perfection and do ability.

If I failed to describe .... sorry :-)

Thank you and good luck !

"Vertigo is what happens when there is dissonance between your balance senses. There is more to balance than just those loops. Your body also knows where it is in relation to other parts of itself, which is how when you are sober you can touch your nose, but when you are stumbling around after a few too many drinks, you end up poking yourself in the eye. Also, your sight helps with balance. There is a large portion of your brain devoted to processing what you see, and one of its outputs helps with balance. If one or more of these senses are not reporting complimentary information, your brain gets confused and simply gives you a dizzy sensation."

I am doomed :-( on VR as even the smallest dissonance between sight and labyrinth makes me sick...

Quote from Whiskey :

AFAIK current tire physics run at 20.000 Hz (the rest of the simulation runs at 1.000 Hz). It's quite an impresive figure with that low CPU usage. Scawen may be having a tough time achieving this again with the new model.

I was with the wrong impression of 100Hz so forget that note. At 20khz maybe it is time for multithreading (hehe each tire a thread etc) and a thread orchestrating the communications and results. Transputer like if you remember...

I throw the dice and enter one more parameter to the discussion.

I thing that calculations sampling rate of 100 fragments per second may be not enough to approximate the behaviour of a car.

At a speed of 100 km/h about 27cm are being travelled every 100th of a second, thus increasing adjustments to the model.

Vector processing and resampling is a solution but increased sampling rate is the only way to calculate high frequency model changes.

I donnot know if the described issue has already being discussed, so excuse me if already done.

Finally Dynamic Look-up-tables is a way of caching data whenever processing power is available but I donnot thing this is the case in driving simulators.

For example on Grand tourismo they are using several convolution matrixes (drop pulses on real cars) to get samples of total deformations specific vehicles are having during a set of conditions. The rest is a good approximation on a model that gets data from these matrixes !!!

Result is average.

I donnot know what type of magic the creator of lfs has made to physics, if it was just a good guess, or a full blown mathematical model, but I believe he is the only single one that can really give some light of how difficult this can be.

And as time passes, age comes, brain slows down, consider sharing.....

Quote from CarlLefrancois :

the problem is to generate a good enough approximation to the "bench" result in real-time.

the "bench" can take as long as necessary to tell you the grip given many parameters, load, temperature, wear, surface, etc. what Scawen is trying to do is generate a real-time approximation using all those same parameters.....

CarlLefrancois, my respect for describing so clearly human race limitations. Also, scaling using more human resources is not linear. Communication is a bottleneck. May be the solution is the forecasts of Ray Kurzweil like The Law of Accelerating Returns etc. Or artificial intellicgence.

Any way, just congratulations...

@Dandy Dust,

One of the best posts read. So much beauty in your words.

Everage (average) computing power my friend is huge today.

Clean code that takes advantage of this power is no where in this world.

Multi threading is the future and after the creation of quality compilers, programming hardness every day is passed to the logic of splitting things apart in software development.

Somewhere here is the loop hole Mr. Scawen has entered.

He needs (fun,way of thinking) to create a perfect code in an industry optimised for mass production. This is a lonely road and thank you Sir for choosing this road vs the easier ones.

I wish him lfs s4 being created by his kids :-) for our kids, in a better world.

prepare to be flamed. Welcome to LFSforums.

Thank's Kirmelius, I didnot know....

I am an IT director on a software development company.

Audi R8 is another design in the platform of Gallardo. Has the awd of labos. All are based on 959 (It has a strong placement in cars history)

Quattro is a general term describing anything from Haldex, torsen and clutches used in audi cars. The same occurs on other companies subaru nissan etc.

Ok it would be mostly kind if there is anyone on this forum owning an impreza sti previous version (2001 -2008).

Has RB4 the feeling of an sti or can it be made using settings to have anything like that ???

Thanks for your time.

It has mothing to do with the placement of the engine. Only center differentials / center clutch make the difference.

You can imagine an AWD car with Haldex type center differential as a front wheel drive system (engine / transmition connected to front wheels) adding an axle transferring torque to the back wheels which has a smart clutch to make variable the torque going to the back wheels.

At 100% engagement of this clutch engine torque is 50% front 50% back. Thats it.

In my view this type of AWD must be considered as partial AWD.

GTR, EVO and ALL MANUAL subarus have center differentials, some models super advanced electronic, some simple friction based. Engine/transmition output is connected to the center dif and the decission is up to the dif specs where to send the torque.

EVO also has one of the most advanced rear dif which makes it very easy to drive fast.

Subaru is based mostly on optimized physics (low center good balance etc) as also center diffs.

GTR is a new world I donnot know exactly.

The writer of the car and driver tester is completely wrong on these. Only auto subarus use clutch at the middle and subaru considers them as partial AWD.

Clutch based cars are audi a3 range (including s3) all haldex ones (VW , volvo honda crv's etc)

Finally very few cars have clutch systems where primarily engine/transmitions output is connected to rear wheels and clutch tranfers torques to front wheels like lambos, audi r8 (a lambo actually) porche 959.

Quote from kimd41 :

Licence "renting" is retarded and I refuse to pay such shit.

Also, Scawen has a real job apart from LFS.

Then we have to wait.... a lot

Bad thing is that failed attempts create history habbits.

No one will create a 'new' higi quality niche market product like lfs, if there is no gain behind it.

I wish lfs is not a failed attempt (always from the developers view)

as a software developer and at about the age of 40, things get worse under presure.

Lfs developer(s) have done the mistake of creating a buy and not rent license for their product.

I believe there is a decission they should take on this. Individuality costs.

Also isn't anyone thinking that lfs earning are not enough for Scawen to survive with full family ?

Sorry for my bad english, have a nice day and good/plenty luck for the developers.
