Hello, would you mind sharing the file, I would greatly appreciate it sice I...

Hi! Here's the file. Copy it to "LFS\data\dds"

Does this work properly with latest 0.7D versions? I got white interior textures with FZ250.

EDIT: nevermind, the file was 460px instead of 512px, so LFS reported an texture error, logically. I made new 512px noisy texture in PS and replaced it, all fine now.

I think the point Pelle is trying to make with this statement is that once you start a VR session with a Quest 2, the headset's refresh rate cannot be changed without backing out of LFS (and the SteamVR connection) entirely. It's the same on the Pico 4 -- standalone headsets which connect to PCs via a video stream simply cannot (currently) change resolution and refresh rate variables on the fly, so there's no way for LFS to "take care" of the refresh rate, unless you are referring to something other than what I am understand as "letting LFS adjust the setting".

Exactly what I meant. LFS tries to lock the fps to match the refresh rate. I can also try to use frame reprojection (36, 40, or 45fps, times 2 equals refresh rate), maybe that way I can remove the frame skipping/stuttering because of LFS 100hz.
But generally speaking, fast paced games, in this case simracing titles are best running at native fps without frame reprojection, as fast moving scenes and objects create very visible visual artefacts. Frame reprojection is made for flight simming for example, I use it in every single flight sim.

Hi Pelle, zemljače, you did the right thing by buying S3, it's well worth it.

I have the same wheel as you, the settings are everything to 100% in the driver, in LFS you should set FFB rate 100Hz, FFB steps to 10000, for most details (with 200 you had before, it's extremely low res, you can't feel anything). In LFS, you should set FFB strength for each car differently, but generally around 20% for GTi and TBO and about 10% for GTR and fast openwheelers. You have to experiment and set a comfortable level for each car, but these are a rough baseline. I use XFG 22%, XRG 17%, RB4 14%, XRR 7% and so on..

As for VR, you should have LFS take care of the fps and screen refresh rate. Ideally, you want vsinc for this as that way lfs will set 90Hz or whatever is the optimal refresh rate for your display, this will minimize stuttering, but may also introduce some input lag. It will be noticeable at 60Hz (16ms), but already at 90Hz it's somewhat more than 10ms which is very little to be bothered about.

Once more, we have a situation where a wheel user is struggling to set FFB correctly because we don't have any way of visualizing the FFB signal sent to the wheel. At the same time this makes me angry, but also more motivated to continue my efforts to develop a stand-alone app that will utilize outSim packets for the real-time FFB monitor.

Hvala za info.
Thank you for the info Rane :)_

Will try again 10000/100, but I remember getting absolutely no effects with these settings. Can't tell why. I will certainly test them again on the same track.

Regarding VR, none of you guys here seem to understand how VR works. First of all, LFS can't adjust Quest 2 refresh rate. I must select refresh rate in the Oculus app, prior to connecting Quest 2 via link cable. Also, in VR mode, LFS greyes out vsync and frame limiter options.

So, VR doesn't work like the monitor whatsoever. Means, I can't see significant micro stuttering on my 60hz monitor, at 60, 75, 90, 120, or 200fps. Doesn't matter. Yes, 200fps vsync off is smoother than 60 with vsync on, because LFS engine works at 100hz, and simple math doing its thing (2x or 1/2x).
LFS is the only sim that I can't have smooth results with vsync on, simply because 100hz doesn't match 60hz/60fps, again vsync on or off. But again, 200fps is closest to vsync on, and I will keep that in 2D.

Stuttering is multiplied in a VR headset. It has two screens that must match the refresh rate, so I guess amount of stuttering is doubled. I tried 72hz, 80hz, 90hz and 120hz, and logically smoothest results are at 90hz, simply because it's the closest number to 100hz. I see a lot of frame skipping, but no suttering, that happens when your fps is close to refresh rate. The best result I'd have at 50hz, 150 or 200hz, but no headset supports that. Actually, luckily no headset support 50hz, as my eyes would melt. I tried 60hz couple of times in the Quest 2, couldn't stand it for more than 2 minutes.

Hi!

Got into LFS many many years ago (probably around 2006-2008), when I even was driving a bit using the mouse hehe. Then I got Logitech cheap wheel (with a spring, no FF), then Momo, then G25, and finally now I have Thrustmaster T300 coupled with G25 pedals. I also drive all sims in VR, with Quest 2.

I really struggle to find ANY info on FF settings, especially regarding FF Steps and FF Rate. I'm currently using 200/100, but I can only feel the wheel resistance, almost no effects like bumps, rumble shaking, etc etc, especially if I reduce FF to 20-30%. I can barely feel fumble strip FX when I bump up FF to 80%, but then I must fight with a wheel pretty hard. MAybe I tested it on wrong tracks, can't tell.
So, what are the best settings for T300, in both Thrustmaster app and in LFS? Any CFG file where I can fine tune FF effects?

Regarding VR, I'm quite familiar with 100hz LFS rate creating stuttering in VR (not matching FPS in the headset). I can see stuttering even on my monitor, vsync or not at 60hz. I limited the game FPS to 200fps to minimize the stuttering, it's almost as smooth as other sims with vsync.
In VR I tested 72hz and 120hz, both produced really bad micro stuttering, and my eyes can't stand that. Tonight I will test 90hz, as it's closest number to 100hz that LFS uses. Wish me luck. If not, I will use 2D exclusively, which is a shame.

My second question is for Scawen - when will LFS be updated to 1000hz? I'm seeing replies mentioning 1000hz in summer 2022. Any update on that is welcomed.

Thank you!
