Quote from Scawen :Thanks but I'm thinking about my month after Christmas, Patch Y will be out this week!

http://www.lfsforum.net/showthread.php?p=635427#post635427

As for the LAG .. maby it isn't lag but just frame drops caused by your hardware? i know that current LFS's sound system uses a lot the CPU but I don't think it effects lag.

Quote from Bob Smith :Impressive feat of technology. I'd never buy one though. If I wanted a near 500hp car, I'd want it to look like a supercar, not like a saloon.

Yes but it costs way less than a proper supercar
I also don't like the shape... but I usually don’t like any spaceship-like designed car so it is not that surprising for me...

As for the weight i think this skyline is more like a fast long-distance cruiser, than a sport car tbh...

In BF1 and FZ50, traction control acts like clutch slip control, it’s a known problem

This is better Scawen.
As for the way you calculate the clutch strength.
It should be a combination of power and engine inertia

If we have two engines with the same power curve, the one which has more inertia doesn’t necessarily need a stronger clutch.
It all depends in the given time both engines how much energy they can store in rotational inertia.

Eg while been airborne after a bump for about half a second, at that given time in which the engines just increase revs, the one with the heavier inertia will just reach lower revs comparing with the lighter.
Unless the engine with the lighter interia hit the rev limiter and stop storing energy in rotational force, both engines are going to store the same amount of energy and the stress on the clutch will be the same when the car lands again.
If the lighter engine hit the rev limiter in that given time, the one with the heavier inertia will store more energy and stress more the clutch so in that case the “heavier” one indeed need’s a stronger clutch.

A simple example.

Let’s say that XRG’s engine inertia is able to store twice as much energy in rotational force while been at 7000rpm comparing to what the XFG can store in 7000rpm.
This doesn’t mean that the XRG needs twice the clutch strength to hold that maximum inertia force.
Because in a given short time (that half second while the car flies over those big bumps in rallyX) XRG’s engine is not that more powerful over XFG’s, to store twice the engine’s rotational inertia force.

I am saying that, because still the XRG’s clutch seems to last way longer in the same conditions comparing to XFG’s as JTbo mentioned.

Anyway I think there is not anything else you can do now, patch Y is coming soon and the clutch is much more usable now in some cars which had problems.

Just promise us that you are going to work it again in the future, with some real data because now I think it is pretty much guess work

I mean that you have borders both up-down and left right so you can increase the overall image size by not changing it’s aspect ratio till you run out of the available height or width. (I really struggle sometimes to explain something simple in English, sorry for that:schwitz

To deal with that you should change the aspect ratio to 4:3 (cause that is the A.R. of youtubes video frame) just for the youtube version by adding the appropriate borders so you don’t distort the image.
eg If your video resolution is 1280*1024 to convert it to 4:3 without cropping you have to fit it in a 1366*1024 frame by adding 2 black borders right-left 43pixels on each side. Of course there is no reason uploading it on youtube in that resolution so you could do it in a lower resolution with the same aspect ratio (4:3) e.g 640*480
But right now I don’t see that kind of borders in your video. It’s more like they are equal in height and width.

Anyway it not worth mentioning… cause youtubes quality is already cr@p and the resolution is so small (320*240) that the distortion between 4:3 and 5:4 ar, is not even noticeable.

For the engine mount flex. I haven’t any arithmetic values but I have seen some engines move a lot even with just hard revups in netural. On some dyno runs, I couldn’t believe how much the engine mounts where flexing.

I tried to find some decent videos on youtube about that.
This is a good example of stock engine mounts

Sometimes this is a problem because the engine moves so much the gearbox, that you can’t shift a gear fast enough so there comes the need for an engine dumper especially if you have increased its power.

And all this flex distortion is way less than axle twist that mentioned above.

Tested all road cars in rally X and I agree that only the XFG is problematic with it's clutch temperature.

It is for sure better. (The way clutch cools down helps a lot) Please keep it in that way if we are going to stay for long time with the current model

Ah i see.
I just always keep the aspect ratio at 4:3 or 16:9 and haven’t faced that kind of problem at all.
But if you have a TFT and using a 5:4 resolution (1280*1024) then it is normal having borders.
But tbh in your case it seems just a bit zoomed out

Anyway nice video making activity

Yeah, there are many other factors that aren’t simulated at all, so maybe the clutch model is ok and is being super uber stressed in some cases by all other super rigid components.

I confirm that the clutch lasts much more in road courses than it did before.
It doesn’t seem to heat up in a slower rate, but it cools down way faster than before. (ok that’s my wrong impression as i now saw what Scawen wrote at the previews page)
This keeps easily the clutch cool even by flat shifting for 4-5laps at a road track but it doesn’t help in rallyx mode

But anyway it seems that clutch's increased heat "resistance" is not the solution on it's own for the enormous stress that forces the clutch slipping by all that frequent loss and regain of grip that happens in rallyx tracks.

Quote from Dillyracer :Then, you should really start to practice your shifting. Since it seems it has been reduced very noticable.

Try bl Rally x with the xfg... the clutch still goes red after 4 laps.

Quote from AndroidXP :Scawen, I did a little laps-to-clutch-failure test, the XFG clutch goes red after about 4-5 BL1 laps of constant flatshifting - seems about fine.

I did test it in BL2 and found it almost the same as before.

After a careful nth check I found that it cools down a bit faster.

Quote from Scawen :

Changes in TEST PATCH X34 / X35 :

AI :

FIX : Updated Kyoto Oval and National pit lane paths
FIX : AI reported obsolete help flags GC_CUT and GC_BLIP

Auto update system :

Patch files are not deleted until user answers "Restart?"

Interface :

LFS icon now appears at top left of an LFS window
Speedo (both types) improved text size and aspect ratio
Loading a grid no longer loads qualify time / laps / wind
FIX : Load grid / drag strip could result in too many laps

Graphics :

FIX : XRG / XRT / XRR showed sky at bottom of side mirrors

Physics :

Reduced clutch heating by 25%
Tyres / clutch cool down even if the car is out of physics

Language :

Latvian language included (nearly finished - please test)

I don’t want to sound rude or something but are you sure the produced heat decreased by 25% because I can’t find any difference at all :ashamed:
(Maybe the clutch grips a bit better at the point it becomes red, comparing to the previews version, but the difference is barely noticeable.)

Nice video overall despite the low fps in some parts and the boring AI divers.

Nice lap.

As for the video, why there is always that black border? Youtube's video resolution is already low and you are wasting many pixels with that…

It sounds from Glenn's descreption as an FWD
I agree that locked diffs should not be so easy to drive... but that has completely to do with LFS's current tire physics.
Anyway principles of making a locked diff setup are the same in LFS as IRL. but i always avoid them

The intel C2D based system should handle it better.

I used to be an AMD funboy before the lunch of the intel’s C2D a couple of years ago. But current intel’s processors are just better in almost any way.

I think it would be better as a visual counter instead of a clipping message…
The first is just informative and useful, the second would just force you use something lower because you will have awfully distorted FF effects on the FF limit…

Quote from AJS :Yup

First thing i tried with the new patch was "Shift-Lock" with the XRG.

3rd gear 6000 RPM press the clutch shift to 2nd and then just kick the clutch without to heel and toe at all.

Nada Zippo niente. The rear wheels didnt lock up at all.
.

I think that’s more due to clutch slipping instead of getting instant grip with the flywheel.

Engines seem to have enough inertia, judging on revs increase and slowdown rate while in natural.

I didn’t like the first one so match... seemed to me more like a wrecking party…

The second about Fiesta cup was really nice and I ROFLed a lot on what I saw @ 4:15:biggrinfl see?? It happens in IRL also

Whatever you do, make sure you have 2gb of ram inside… espesialy if you are going to use Vista.
If you what to keep it cheap you could have the C2D 6550 instead of the 6750. They both have exactly the same core... only difference is 330Mhz which you could clock easily on your own without even touching any Volt setting… Just make sure you have DDR ΙΙ 667 or 800 because the fsb of these cores is 333mhz (DDR 667).

Quote from Rubenz81 :
So basically the lack of (slight as was stated before) chassis flex it's the problem of the high understeer of lfs on tarmac? How it could be improved?

No, chassis flex on its own will it make it even worse.
Now the granit rigid chassis gives the ability to utilitize the full potential of your suspension setup.
I think it is more about the tire model that will improve any kind of unnatural behaviour.
Anyway I don't think that there is extreme under steer now on the FWD cars... you can do pretty match whatever you want, regarding the vehicles basic characteristics, with a proper setup.
It is normal for a front weighted car to be generally understeery...

My only problem is it feels better for me at 128 FF steps but as I see it is only me
