Quote from Skytrill :LFS is by far the most convenient and comfortable experience I had in any racing games in VR. You basicaly just sit on your fat ass with your wheel and the tiny (useless with 99% of other games) oculus remote controller and click the LFS icon from your desktop or from the oculus panel and Voila. The virtual keyboard from LFS works with the Oculus controller so you don't even need a keyboard and mouse.

The refresh rate is an issue if you are looking 90 degrees on your left or right while driving, something I had no idea was an issue before I read about it from others. Correct me if I'm wrong but the same issue exist for monitor users depending on their refresh rate settings. Maybe if Scawen could make LFS physics runs at 180hz that could help much.

Yeah the issue is their for monitor drivers also,to be honest i focus that much on the other cars and the road in front of me that scenery ect i rarely take notice of unless it's at the end of a race Smile
Quote from Ped7g :I have no issue to accept LFS is currently not ideal for VR because of the 100Hz physics clash with headset refresh rates. And I can also easily accept some person may feel about this strongly and consider that as show-stopper issue for them.

But saying LFS has "no VR support" is in my eyes just pure insult as it does plenty of VR support already and doing many things very well. And especially as LFS was *first* racing-simulator to have decent level of VR support, way before the other big names managed to adjust theirs sims.

So I was just trying to explain that to MaartenB, that his words are technically way too much incorrect (although I guess it was meant to mostly deliver how he feels about it, so I guess LFS devs could handle it and take it as feedback, which is always important and thank you MaartenB for at least commenting about it).

The thing is with VR it's more of an unpleasant experience with Pcars 2 and A.C with stutters, which i have also put many hours into, the only plus on their side is graphically better

With ACC to get it to run at a stable frame rate in VR, it looks worse than LFS and iRacing.

Can agree with you on that Smile

not sure if bug or because its pretty far out in OOB country.

what puzzles me is.

why do i fall through editor objects? in this case the road surface.

the plan was to build a freeway all way around westhill.
but as replay shows,had to make a D-Tour because encountered this small issue.
(Dont mind the driving and track is defo not finished at all).


not sure if posted correct, but thinking that must be "fixable" ?

im using U11 for this!

You reached a point which is outside the map square system. The rectangle of map squares is set to the size big enough to include all the default ground that is set to have physical properties. Outside that, there are no map squares for your objects to be registered on.

The map squares system is designed to rapidly identify nearby objects to check for physical contacts during each frame's physics calculations.
i guess thats one corner i need to cut then. Thank you!

(THE WIZARD DK) DELETED by THE WIZARD DK : posted that wrong i guess. technical thing
I have a DD wheel and once you try the FF of this version you don't want to go back to the standard U version but LAZY doesn't work with this test version!!

please Scawen updat LFS with the new FF cmon
Scawen please learn german and read this: https://misie.ga/vsync-freesync-fastsync-cpugpu-sync-engine-lag-reaktionszeit

To make LFS smoother.

I bought a FreeSync Monitor and at 100 Hz (dont know if FreeSync works with LFS, but without it will be never smooth, dont know why) also sometimes come the common known stutter-time, maybe because CPU/GPU fell out of sync. My Radeon Vega is fast enough, LFS need only 12% GPU.

And i have to say: The FOV-Setup-Possibility should be completely removed. When using 3 Monitor setup is for every monitor another perspective and projection necessary!!!!! And the completely useless FOV like 30° and 160°......... The 160° cause only a extremely distorted picture. And the 30° are maybe for people which playing with a small TV in 4m distance...... The FOV-Setup should be the same like it is. If a Human are sitting in 60cm distance from the monitor are this ca. 60° FOV. Maybe maximal 75° are a Compromise. Because you need a completely different projection technology for a wider FOV, Thats the reason why the Pimax completely fail, because the projection go to a flat Disc and needed is a spherical projection method for wider FOVs with stereoscopic Glasses. Stereoscopic Glasses with wide FOV fail because the projection method is not spherical.
Quote from cargame.nl :G-sync (Nvidia) and Freesync (AMD) are inventions of American/English companies. Why in the world you think German is the leading language all of a sudden with this technology? Lol.

It doesn't have any relation with a particular game.

Everyone knows German is the most commonly spoken language in international commerce. The compound words allow you to concisely express an idea in only 10-50 characters.

you are right, i was just joking because i dont know a english article and this guy have also many other very good articles. Smile
How to make LFS Smooth like Butter with a Samsung 144 Hz Freesync Monitor?

Misc
1. Disable Vsync
2. Maximum Frame Rate = 100
3. Sleep every Frame = Yes (Westhill is also without this Option smooth, but Aston not)
4. Maximum Buffered Frames = 2 (0 and 1 have i not tested)
Screen
5. 1920x1080 @144 Hz. (Must be changed via In-Game Setup)

Only when the Monitor at 144 Hz is no tearing effect, maybe this is the magic Freesync frequency......

The Monitor are in all cases except Full Screen TV better at 144 Hz.
i use vsync with 2 frame sleep. however im also using Nvidia and have the card set up so i do get a smooth (very) picture.
i got 0ms screen. and 600Hz Deepfield. yesterday i fixed FOV and more on some cars. as my screen is rather far away but also rather big. what i noticed is i can set FOV/view as i wish on most cars. except fxo. its border seems alot lower than forexample fz5. in fxo that makes me feel like im almost sitting on top of the steering wheel as to fz5 where it feels like im actually in the seat. not sure why that is. but hoping to see more border towards the setting in the future. geforce GTX 1660Ti.the only time i seen stutter on the fames was yesterday when many from other continents than europe is online. i had a little bit of stutter when above 37 users online. otherwise i had nothing at all. must also point out that there was alot of pings jumping when it happened.

EDIT:
Miscrosoft stopped support of MC virtual machine for OS older than win 10.
will this get any performance issues with older OS ?
Nvidia GT 1030 on that one.
The FOV-Setup is not the right way to setup a good in-car-view because of the big distortion. Objects in the middle are then very much smaller than objects at the margin. If you setup a extremely wide FOV and turn around you see what i mean. This effect disturb me also by smaller FOVs. Also at 75° is this effect still present, but because you watch also in a similar angle to the outside objects like they projected to a flat disk are this not so much disturbing and cause no motion sickness. There is a reason why some CS-Pros playing in 4:3 with black bars..... The distortion is the reason.
i came to think about the night cycles.
what i havent seen in pictures is..
well you got the sun and all looks great.
but the moon ? i didnt see any Moon in screenies.
that and ofc some stars would be very cool to have.

22 min of your time to watch how it works ,even though im sure you already know this :

Maybe a stupid question, but:
When I drive with a Pimax 8K and 20 AIs with this current test version, the frame rate drops from 80 to 40 fps at most times. But it depends on how many cars are around me. Is the GPU or the CPU limited here? I guess it's the GPU (RTX2070) because the 20 AIs have to be calculated at all times, even if I can't see them, right?

By the way: I could fix the problems described above by starting LFS via a user-defined entry under "My Games" in the PiTool control panel.
You're CPU limited. LFS does a lot of CPU-side calculations. It's generally very light on the GPU.
LFS uses only one CPU core.
Yeah but the huge drop here is either graphic or collision calculations but my guess is that there is not much here as long as there is collision.
I have also framedrops with Oculus Quest (Link) when i use more as 6 AI.
Its fall from 72 to 36 Frames.

Oculus has an feature that called ASW (Asynchronous SpaceWarp)

https://developer.oculus.com/documentation/native/pc/asynchronous-spacewarp/?locale=de_DE

But.... when i use an old Track (Fernbay) i can "easy" use 15-20 AI with stable 72 frames.

I am not sure why this only happens on the newer Tracks. Maybe the AI need more calculation on this Tracks...


Sry, bad English....
The new tracks have far higher model detail, therefore the Quest is struggling to render those tracks. ASW will be kicking in when your frames drop by half anyway, this has nothing to do with LFS inherently.

To be honest, it's a testament to LFS that it runs that well on the Quest at all to be frank.
His PC is just too weak.

The Quest with a Link cable is the same as using a normal Rift/Rift S headset. Lower FPS than the Rift (90) and Rift S (80) and a bit less detailed as it has to compress the video to send it over USB to the headset.
Now i know how to run LFS smooth like butter, but this works only offline and not online. It seems online are very much more GPU Power needed. The AMD Vega can only be used with full power with DirectX 12. Euro Truck Simulator run not 100% smooth because the GPU run only half power with DirectX 11. Creating alot of pseudo-Frames for heating the Graphic Card is not the right way and make it de facto not smoother.

The Quest (Link) need a litle bit more CPU & GPU workload then Rift, because of the compress. And it has a very little delay against the Rift. the biggest "problem" is the 72Fps lock Shrug . But it is still immersive and fast.

But 2 days ago I finally made a jump and switched from fx8350 to Ryzen3600 and the FPS problems in LFS are finally history.


Only when I turn up the AC properly ..... it rattles on the other side and the graphics card can't keep up ...
