he has discovered lfs yesterday ... give him some times 
@Scawen : what I see/feel :
* with vertical synch (60 fps here), I find some disturbing transitions between frames. It feels not so fluid in some parts, more often when going at high speed, but even in the corners of Blackwood it is sometimes a bit weird to me. One note : Sleep is = 0.00 in this mode (while my cpu is almost doing nothing)
* at 100 fps I still see some "missing frames" I will call them. Again, it is obviously subjective, but it gives the feeling of a computer slowing down when doing the job
* at 150 fps it looks the same as without limit
@Degats : I see what you mean, and totally agree.

A powerful catheram or a 996 GT3 on a karting track is just great 😁👌🏻
Ok, noted. I think I was misunderstanding sleep/cpu time/cpu tick.
Indeed when more AI are present, the percentage for physics is at 20, while alone it barely reach 1. What is logic.
A simple side question : is LFS limiting the cpu usage to compute frames ? for instance, in my case I suppose the clock frequency is getting somewhere at 5GHz when a single core is stressed, and so LFS displays a huge amount of FPS (more than 1300 when alone). But in the mean time LFS knows that my screen is limited to 60Hz => how is handled the thing in the end : does the couple cpu/gpu has really computed the things (1300 fps), but forbid the gpu to send this flow of framerate to the screen ? or is it done anyway, and the screen discard the unecessary frames ?
I know in the past there was some strong proselytizing (
) for using vertical synchronization to have fps matching the screen max frequency, but at my level when doing some tests in various games, I tend to have a slightly less fluid experience than not using it ... it is of course very subjective I guess.
Anyway Scawen, I hope you wil succeed to find how to implement the facility for multithreading capabilities for LFS
, it ease a lot the cpu consumption for a given result in the end.

, it ease a lot the cpu consumption for a given result in the end.I just made a quick test on Blackwood for this feature :
While driving alone, if I limit the frame rate at 250, I can see the sleep value at around 70.
If I do not put a limit, I am reaching 1200-1300 fps, but this time the sleep is around 0 => I can see a core going at 100% of cpu usage (single core app behaviour I suppose)
If I use a full AI grid without limiting fps, I can see them dropping to 300-350 while the cars are present (a lot more if you are "alone" in your field of view).
The Draw is almost always identical I would say, in my case ~70 when not limiting fps. Physics is going to 15-20 with the full grid of AI, and almost 0 when alone.
How is this working : does more sleep mean more cpu "free" time ? is it the same for physics value ? if so why would 31 AI with you cost less less cpu for physics than when alone ? Or is it a display showing the average consumption between each part (the sum is close to 100 each time) : physics, draw, etc... and the "free time" (sleep) ? I tend to suppose it is the last one...
not yet the hybrid/knobbly for GTR cars ?
I will test u14 later this day. Interested in those CPU usage things

and to be more realist, when the graphical update and the tire physics will be released (as a test patch(es) obviously), the next challenge after releasing the whole thing (indeed there will be some glitches I suppose) for Eric will be to release the two other tracks for S3 content ... so, interiors ...
Nice info kagurazakayukari
We know that Eric has to come back to Kyoto to fix some holes, but I guess you may have motivated him to fix the Japaneese texts, knowing is aim for perfection

lol. Anyway, you have it into the setups of the xr gt : ABS : on/off option in brakes part.
It may not be optimum, but I am sure it will be fun. I remember having done some laps in the past with the FXR with hybrid tires, it was insane
Note that rallycross cars irl are not having necessarily crazy ride height, and if stiffer suspension is needed to have the necessary height, the drivers will adapt
APPROVED !!
Making those GTRs some rallycross machines is indeed very appealing Same for those who wants to have AI online.
For drifting, I have no knowledge, but 65° seems crazy, but maybe real, do not know ...
What bothers me the more, is to not know :
- what means the "O" in FXO
- what means the "50" in FZ50
...

Happy new year guys ! I wish you all the best for 2021. 🤘🏻
Wow, impressive guys !!! Wish you all the best for the year to come, and a merry Xmas to you 
Thank you Degats for the comparison shots

You have to contact the team by emails, more chance to have them reading emails than the forum : https://www.lfs.net/mailus
correct me if I am wrong, but there are already serious discount according to where do you buy your licence, no ? this was especially done for Brazilian people (but not only) iirc.
And I doubt Scawen and co are keen to play the black friday thingy

... but maybe Eric is still struggling on South City and Kyoto ...
Eric will simply have to add it on the Scirocco when it can be delivered
Other cars seem not concerned due to the period of "production" they seem to belong to !

Hot air temperature or altitude may give an advantage to na engines over turbo ones. So according to where your track is located, it may influence the overall performances of each car... Even if not by that much of course.
And of course having temperature to be managed everwhere is something interesting on the paper, but indeed may not be that nice in the end ...

Indeed, quite rare to have engines overheating nowadays. But having air temperature and pressure impacting engine performances would be a really cool feature !
I do not think Eric is planning to spend over than a year fixing few holes on two tracks and doing magic on Fern Bay !
NB: Eric do not forget jocker lap layouts on rallyx tracks ☺️
Are the equations completly different when on soft surfaces ? I mean : dirt, grass, in the future maybe snow (why not snow), I suppose the behaviour may differ due to the resitance encountered by the tire.
not yet
It disturbs me a lot when I play a little in LFS and see the GPU temperature almost as it was idle whn I quit ... while other games like ACC are bringing it to 80°c
