Quote from Whiskey :

Do you guys remember that this track was what caused Scawen's quest in search of a better physics equation? He already did these test and saw that it did not match.

I definitely do. I'm actually dying to see Scirocco with the new tyre model, that page has Scirocco laptimes of Tiff Needell (on wet though).

Quote from VicaNo :

btw give me your experiment set for lx4

It's just RACE_S with +25 kg and %19 intake restriction, to get 105 HP. (says on the page)

You know other sims have side-by-side videos of real laps and replays of a car/track pair, I was curious how LFS performed under such a comparison now that we have a real track.

On this page there are several lap times of Rockingham National layout. Since none of our real cars are on the list, I decided to give a go with #52, Caterham 7 1.4 Classic (1:27.87). Checking with the specs on this page, I've added 25 KG to LX4 and added some intake restriction to get 105 HP from the actual 140. I'm guessing it should be close enough to the real thing.

On my 3rd or 4th lap, I was able to post 1:23 something. (RACE_S, cold tires, racing line on) and trust me I'm not that good with it. I'm pretty sure someone experienced with LX's can crush that easily, I'm guessing 1:19 or 1:18.

What do you guys think about this? I'd like to see similar tests. Maybe someone who actually raced on Rockingham with similar cars of LFS would provide valuable information.

Note: There's also Opel Speedster Turbo on the list (200 BHP, 930 kg), so maybe RAC would be another good candidate after setting power and weight (245 BHP, 800 kg).

Quote from CLRS530 :

Writing about competitive racing games in the official LFS forum really is missing regard. I appreciate that the devs/mods tolerate that though.

But come on, I often noticed that you guys do that in the General LFS Discussion.
That's the absolute wrong place.

Well that's Blackwood so it looked like it's related to LFS. Since we don't have a "Videos of other sims including something about LFS" discussion, this one looked fitting.

Quote from Kristi :

First of all, iRacing doesn't have a porsche and this one doesn't even look close to what iRacing has, neither the interrior nor the chassis. I'd rather guess that's a cheap conversion from an rFactor 1-2 GT3 mod.

Apparently that's true:

Seeing BL1 rendered in a different engine is interesting.

For information, the (last) official statement regarding this topic:

http://www.lfsforum.net/showthread.php?p=1764267#post1764267

Search Scawen and Scirocco if you want more details, there are interesting posts to read around here. Good luck!

well that sorted out things a little bit, i must have missed that post... thank you.

Quote from Bose321 :

Why would the whole physics engine have to be redone?

it may not has to be, i just can't think of anything else taking so long.

Yes, I know: Dead horse, when it's done, bla bla. Just my theory:

S3 will be (hopefully) providing a real-car/real-track combination for the first time. Sure we have real cars at the moment, but I don't believe they have proper data or lap records on Rockingham.

I believe Scirocco on Rockingham came up with non-realistic results - in terms of lap time, driving line, whatever - so there's quite a chance that we have been living a lie under the illusion of realism. Maybe the whole physics engine has to be changed, or they are trying to go nuclear on tyre physics for compensating, I don't know. I can't think of anything else that can cause years of delay after everything is ready.

TL;DR: Maybe VWS on RO1 revealed LFS has to be re-done.

XFG in Rain Edit:

OK I wasn't around for some time, this post is an all-in-one reply

Thank you very much for all your compliments and criticisms, I should explain the following with the picture, but it's never too late eh ?

No rain drops flying / No dashed water: I know, and I'm as displeased as those who notice that. I tried my best, but it was simply one step ahead of my phosotshop skills. I was not satisfied with the "realism" of anything I tried, so I decided to do nothing instead of coming up with something "ugly". So we have a car which can literally drive through the raindrops.

No sign of rain on the car: Come on, it doesn't look dry does it ? It just doesn't "interact" with rain..

Locked Up Rear Wheel: I'd like to thank for previous explanations, yeah it does lock up. It's easy to see small hatchbacks cornering on 3 wheels. That locked tire in that picture IS in the air, but the angle just wont let you notice that.

Quote from 5tag :

(...)Now that you look in the "mirror" three things are strange: The mirrored car is squeezed vertically, it is not blurred horizontally (which resulst in very sharp vertical lines) and on top the mirrored car is out of perspective since I assume it is only a copy of the original car in the picture.(...)

Vertical squeeze / Perspective weirdness: Thats the closest realism I can get to, pardon my lack of imagination, tho I think the whole perspective "trick" (yeah it's the duplicate of original image) is satisfactory.

Reflection blur: I just wanted to keep the details. To be honest, after editing this picture, I started to notice the reflections of cars on rainy days. And unless there's a pond on the surface, or a road completely wet with a thin layer of water, you see nothing but just the reflection of (head/tail)lights - with a heavy blur. Actually I can dodge this problem with claiming "oh it's my art, it's the way I wanna show the emotion, bla bla" but it wont save me right ? :P

Quote from 5tag :

(...)What I was earlier criticising were the skid marks. Their path is too much of a curve for a car that seems to be going so fast, for me it looks totally strange since the car in the screenshot is obviously in control(neither weight shift nor steering to the sides). Talking about the lack of steering angle the locking rear wheel makes no sense to me either but that could be just me. Do I have to mention how realistic I find utterly dark skid marks on a very very wet road to be?(...)

Skid Mark: The problem is reflection. The road reflection claims "this is one hell of a wet surface" while what I intended to do is just some ponds. I dont know if one can leave skid marks on a damped/wet asphalt, let's say I just assumed it.

Skid Mark Curve: This is the most disturbing detail for me. I wanted to tell that the car is about to dive into the curve, and to "emphasize" the locked up wheel. Apparently trying that with a curved skidmark is a lousy idea.

Misc:
Believe or not, there's a $hitload of weight shift on that XFG. My setup was hard track with low-pressure front tires, brakes adjusted to full front and dont-know-how-much-but-too-much power, and add 190 kg of weight on %100 front of the car. I slammed on the brakes at the end of BL1 straight with +160 kph and dived in. The reason for this strange setup is to show suspensions squeezed in front and stretched in rear, for a more dramatic view - yet it was not enough to show it on 3 wheels. Why it looks "too in control" is just because the narrow field of view, and the angle. And there is a steering input, which locked up that inside wheel. It was really locked up and in the air when I took the screenshot.

I don't believe there's a chance that an XF GTI can make its brake discs glow either, but there's no XF GTR in demo.
---
I was stuck in demo for a long time, I have ~4000 laps on BL1 with XFG with a PB of 1:33:67, and I guess I can claim that I'm no noob. I'm S2 licensed for a only couple of months, I usually race on IHR for now.
---
I'm no photoshop guru, I have some difficulties in conveying the ideas from my imagination to the canvas - "skill" is the word for it I guess.
---

So that's the story. Please don't think that I'm rejecting your comments, it's the comments why I share this screenshot here. I may have picked the wrong words or expressions while writing this post (as you might have noticed, english is not my primitive language), hope I did not come up with a "dont criticize me" kind of a tone.

Thank you again for all your attention...

yet another rain edit, and it's an XFG from my demo days. hope you like it..
