If LFS is dead, we have here the largest gathering of people who like to play with dead things. World guiness record?
I do not talk about the FFB problem. On/off grip is a tyre modelling problem.
In most mods tyre grip on the track is falling too quickly after the grip limit->unrecoverable spin. This is not realistic, far more unforgiving than IRL.
In the caterham mod, the tyre grip curves are different...almost flat after grip limit. And this gives for me something which counters ISI tyre model flaws.
Don't know how to explain. It feels good, like real tyres. Small mistakes make you slower, and do not send you in the grass. It goes in the right direction more-forgiving-but-deeper where all recent sims are going (LFS was first exploring this path).
Anyone tried caterham mod for rFactor?
For me this mod is very different from others in rFactor, and gives a very similar way of controlling the car than LFS. With this mod there is no more this typical rFactor grip going on/off and causing unrecoverable spin.
FFB still needs to be tweaked, but at least cars behave as expected.
This mod and the laser scanned track -> very enjoyable.

All this is good for us. To sell more games, developpers compete together to get the nicest graphics. To sell more cards, computers, hardware companies compete together to make more powerful cards, processors.
To enjoy it, geeks invest a lot for games and hardware and keep this innovation engine fuelled.
And us, average customers, we buy from time to time games and hardware two years later, for 1/4th the price geek paid for it, and enjoy massive improvement year after year. Whatever shiny, brilliant, realistic graphics one can see, one just have to wait two or three years to have it at home.
Geeks and their fortunate parents diserve a monument.

Woohooo, this is great news! Thank you. It shows windows 7 is more XP than Vista. With this I suppose it is possible to use three monitors without matrox triplehead2go, and with a higher resolution (th2go is still limited)!
And are you using the latest nvidia drivers? I remember reading somewhere that they intended to stop supporting horizontal span with new drivers. Maybe now horizontal span is done at a lower level inside windows and nvidia drivers see a new possible resolution covering both screen when they enumerate possible resolutions and do not have to care about it.

Do you mean windows 7 supports horizontal span (display extended on two screens without any hardware like matrox box needed -> for example 2 1280x1024 monitors become one large 2560x1024 display and all applications like LFS see it as a 2560x1024 display and render on both screens without even knowing about it)?
It seems to me Vista did not support it. It would be great if windows 7 does.

If this is your new system, I bet your old system is 10 times better than mine. Do you sell it?
I found last week this very affordable MDF cockpit. Around 100 euros and you need a seat. On racesimcentral customers seemed happy with this product.

The caterham mod for rFactor is quite special. I checked how it works and it uses tyre lateral force curves which almost stay flat beyond the grip limit (after 12 degrees slip angle).
And this reproduces a lot better what happens in transient state above the grip limit: you can for a brief moment ask more from the tyres than what they are supposed to give, and this is enough to keep control.
When the transient behavior of tyres is not modeled, it seems to me the only thing to do is to use tyre curves which almost stay flat after the top instead of decreasing quickly. Like this mod does.
I suppose LFS either has flatter tyre curves than rFactor usually uses, or models tyre transient behavior.

For me all release dates for all kind of projects (building, bridge, road, software, hardware) simply give an indication about the most probable date if there is no major unexpected delay. It is just to give an idea and can't be accurate all the time.
100% accurate release date = no release date at all. That's the only way.
Personnaly I prefer to know Scirocco is coming around chrismas or beginning of 2009 instead of no information at all.
But we can be sure after this experience that Scawen will give even less information about development than before (and he is right to do so, unfortunately for us).
Great news....it will be even better than expected. 
Real brand new road car! real setups! real ABS! real ambiant shadows! Amazing, I was almost sure VW would not let Scawen use the Scirocco, so glad I was wrong!
I did not read everything... but at least in the first 6 pages none of the guys complaining LOUDLY thought a single instant that Scawen could not work anymore this week because of a serious reason.
"What? No Chrismas gift? WHAT? NO CHRISMAS GIFT???? But I paid you 24 pounds two years ago, you *****, and you can't even work this week??? Aren't you ashamed? How could you? I don't want to know your stupid reasons... nothing can justify your crime."

Crazy polygons gone here too (fx5200).
WOW, like the shadows, cars are not flying anymore!
I have a probleme here with this version. I use a quite old graphic card (GeForce fx 5200) but until now it was working very well (80 fps with low quality).
Now most of the screen is blinking and there are artefacts in textures. But it seems this blinking only affects objects depending how far they are from the camera.
edit: I see the same things like Danas.

In France we got this:

Few years ago it was very popular and you could hear it in every wedding party... of course while eating. Bon appetit!

Just my opinion...more an hypothesis than anything else. I repeat this is opinion not information:
I think Scavier may have received some requests to do some specific adaptations of LFS for firms or events, like for example the WW Sirocco, the formula BMW...maybe a special version with custom tracks for entertainment places specialised in racing simulation. Such places open in many countries recently.
LFS is their property and they can do whatever they want with it, they did not promise anything excepted continuous improvement at their own pace. And they obviously do it regularly.
Of course such adaptations are great opportunities for them, they brilliantly diserved it, but I suppose it is rather annoying for them to communicate about it, because the licensed community could feel neglected. The best thing they can do is let people find about it unless it brings some new content to the licensed/demo version.
We all know how people are....the less we pay, the more we ask

For me LFS was the first sim designed from scratch to be mostly on-line. All other sims before are offline sims with a good or bad netcode if you want to use it. In all other sims before LFS, it is more comfortable to play offline if you have half an hour spare time, whereas in LFS you can get quality races online immediately.
iRacing simply takes LFS concept, a 100% online simulator accessible at any time, and adds some commercial power.
SamH, iRacing is definitely considered as the new leader for FFB and track accuracy, without any doubt. I can bet this will influence next sims and they will feel different from now.

Finally I understand why you say "it sucks" in english.
Amazing, this is a gear box applied to the power of wind!
With a zero reduction ratio (fan does not turn) it works like a small sail.
With a positive reduction ratio, the fan pushes against the wind, and it is like using a smaller sail in a faster wind. Higher top speed, but less force.
And with a negative reduction ratio, the fan pushes in same direction than wind...so the wind turns the fan, and the car goes backward!!

That's why they invented a-lerts.
Some time ago I was working on a large Java GUI project (100 thousands lines of code). The kind of GUI in which multiple users interact with huge tables and charts refreshed in real time.
We discovered that the simple countless objects generated during the refresh process, one rectangle per cell update, then dirty rectangles are merged and clipped according to documents frames....were causing the garbage collector to use 100% CPU on any average PC with only a few documents open (even with documents minimized!!!). This was not a design problem from our side, we had no control on these objects because they were generated inside Swing. As soon as we used native components directly instead of swing, the CPU load fell from 100% to 5% for the same documents.
These rectangles objects were used only in one function and should have been destroyed when the function returns, but the Java too general collecting process caused them to go through the entire cycle...
In C# this is different because simple objects like structs are allocated on the heap and cleaned when the function returns. But it is very easy to have problems with Java. It is not flexible enough in it's allocation mechanism and does not give you the choice. If you use Java in a game, you have to be prepared to spend some time implementing objects pooling and cleaning strategies.
Techland used to develop games in Java. Chrome engine, Expand Rally, Call of Juarez are written in Java
Even with fixed timestep you can use a similar cpu-saving strategy. Every timestep the engine decides if a physics update is necessary or if it should keep vectors previously calculated (like acceleration). This way you get advantage of fixed timestep and variable timestep.
The main problem when you slow down physics update frequency is that it is difficult to predict when you will have to increase it. Because you have to increase it BEFORE things occur to avoid low-frequency problems (collision bugs for example).
Am I wrong?
Anyway I am very surprised. I always believed physics engines were running at 100 hz or lower for previous sims, and 300 hz only for new generation sims like iRacing because it has to cope with small bumps at high speed.
Yes, but this can be avoided if you integrate everything carefuly. Using varying time steps can work...but it introduces many tricky potential bugs, and make things that should be easier like integration between fames become much harder.
It is like using a rotating referential to calculate everything. It works if you think about it all the time.
What strikes me reading this thread is that conspirationists are experts in one thing: turning a fact's meaning into it's opposite. This is a rhetorical tactic based on sophisms.
They turn the 9/11, the Lusitania, Pearl Harbor, D-Day into US attacks.
And the same way, they turn all possible answers in this thread into fuel for their theory. Everything...using sophisms
- USA produce weapons.
- When you produce something, this is to use it.
- Weapons are used to attack and kill.
- Then USA want to attack and kill.
With such sophism you can demonstrate anything.
There is no point discussing with people using sophisms. They do not respect the basic rules of logical discussion and therefore will always win. Not only they will reject easily what we say, but turn it into arguments supporting their theory. They are not interested in truth, they are interested in posting as many times as possible thier theory and using their sophisms. I understand now that the only possible answer is silence.
