Ive been waiting for news for ever! anyone know anything on whats goingg on?

Its windows Vista Ultimate (OEM) my pc specs are
Intel E6600@ 2.4Ghz
Ati 1900XTX,
2 gigs of Dual Channel DDR2 677MHZ
500 Gig SATA hd
Partitioned to 100gig for vista, 200 gigs for programs and 200 gigs for video's

anyone know what causes this?
Or how to fix this. It causes the video to run very choppy sometimes.

After 30 secods is trhe video


Also, using the replay, is there a way to pause the action? and still be able to use the camera controll. Like just pause the motion of the cars?

Hot Lapping.

Yeah but i have a internet connection on this computer (laptop). I need a internet connection for the computer i want to use for lfs? there is no way to activate with another computer with a internet connecion?

Heya. I have a computer at my friends house right now. I was showing her racing sims.. lfs. However, I cannot access the interent with my gaming computer, All she has is a laptop with a wireless connection. ( and dosent know where the wirless router is, or any of the passwords) Is there a way i can unlock lfs on her laptop and transfer it over via cd to my computer?

Does anyone know what the patch V will contain?

Ive been watching for updates sence the BMW. Has the guys taken a break? or are they planning something huge? Or did i just miss the posts on the forums

Quote from bal00 :

I'm starting to think that the rest of the car may be real the problem.

Let's take a look at this first;
http://www.ismirdochlad.de/decel-slip.gif
(For the non-Germans, the graph shows slip ratio vs. friction coefficient of a tire)

The peak we see in the graph is also in LFS, you can verify this by looking at the longitudinal acceleration readout(F9) while launching with lots of wheel-spin. There's a spike in acceleration right when the tires regain grip.

If we were able to hold the tire at 20% slip (or wherever the peak is in LFS' model), we would see better acceleration. Problem is, you can't get near the peak without going over it. You can have wild wheel spin or virtually no slip at all, but nothing in between.

So either the edges of said peak are simply to steep, or the problem lies elsewhere. I suspect if it really was as simple as tweaking the slip vs. friction curve of the tire, this would have been fixed long ago.

My guess is that real cars behave differently because they have lots of slack and flex in the drivetrain. When you see a real car slightly chirping its tires, it's not a constant slip ratio like in LFS, but it changes as the engine rocks back and forth in its soft mounts, the suspension flexes and the driveshafts twist.



When you launch a car in LFS with spinning wheels and the tire goes from slip to grip, it STAYS that way unless you apply a lot more throttle to break it loose again.

When you launch a real car with spinning wheels and it goes from slip to grip, suddenly there's a lot more torque being applied to the engine because of the additional tire grip. That means the engine will move inside the flexible mounts. Since the engine moves relatively quickly, the maximum travel inside the mounts doesn't just depend on the torque being applied to the engine, but also on the engines momentum. That means it'll move quite a lot and then be pulled back towards its center location as soon as it runs out of kinetic energy. Moving back towards the center location will now in turn apply additional torque to the wheels and break them loose again.


Long story short, a real tire doesn't just go smoothly from 24% slip to 20% to 16%. The slack and flex of the drivetrain will make it grip and knock it loose over and over again several times per second (the frequency depends on how tight the drivetrain is), so it's basically cycling between 16% and 24% slip the whole time, which can have a significant impact on the transient phase between slip and grip.

very well said. However dont some of the "race versions" of cars have tighter motor mounts, and less slack in the driveline. Dosent tire pressure, wear on the engine, transmission, wear on the tires, motor mounts, chassis flex/warp, surface type, type of car overall, computer control throttle, (some newer cars) and engine managment, all play a role in howe a car launches. Only reason i ask is becasue, years ago i used to have a camaro, launching was tricky becasue of the type of tires i had. it seemed like it was either grip or no grip, But i have a newer cadillac now with computer controled throttle. So if i gas it, it gradually leans into the throttle, but someties i can a little bit of spin, then chirp, chipr chirp...

I think that It could be modeled in LFS by somehow replicating either the entire driveline slack. Im sure there is a way to replicate this

hehe i just read them.. didnt see them up there... I managed to fix it.. Seems it the router reconizing the other computer as a network .. i guess the "host" had a clear line to the internet .... or whatever... I fixed it by turning on DMZplus Mode on the guest computer and it worked fine..
thanks for your help guys

well i dont want any cracks becasue i did pay for S2. However i think i should be able to use it online with 2 computers that are in my house. But if i use the other computer to host.. i get that track data error message

Oh and .. what would i chane everything to?

well ive tried using both computers to host.. on one computer i use the 192.168 ip and it says from the guest computer "cannot load track info"
so i dont know if that has anything to do with it.

Connection-specific DNS Suffix . : gateway.2wire.net
IP Address. . . . . . . . . . . . : 192.168.1.65
Subnet Mask . . . . . . . . . . . : 255.255.255.0

for my computer and

Default Gateway . . . . . . . . . : 69.183.243.25

for the other computer.. .

Both computers connect to the interent via 2wire model/router.

well the computer i host off of is 69.183.243.26. and the other computer is 192.168.1.54... Ive tried that and it says "did not recieve track data" or something like that

I have 2 computers in my house, both have s2 unlocked with the same username. ( i only race one online) I have both computers networked togeather with a 2wire router, and i share files consistantyl. All firewalls are off and i checked on the ip addresses.

When i click "start new game" and selected Local as my seettings . i completed the blank fill-ins. (ive tried leaving the ip address to auto, and setting it manually) the ip address is in a xx.xxx.xxx.xx config and LFS for some reason does not accept this and gives me a "You must enter a valid local network ip address"

any idea's?
