Car moving with view in VR.

[Navigator]

Hi guys,

About two weeks ago I got a Lenovo Explorer and AC was running nicely.
Well, it still does, but sometimes is becoming most of the times: the view seems attached to the car.
Moving your head forward, makes the whole car and picture altogether move forward too.
At first it was one time, now I have to restart the game and Steam VR about 8 times before it is doing what it should do.
Its not only forward, it is in al directions.

Is there something I can do to overcome this?

Am I correct in thinking the lenovo is WMR? If so, I have the HP Reverb which is also WMR and I experience the same thing periodically. I think it's when the tracking doesn't fully work. I usually just go into the WMR settings and reset the seating position and it figures it out. It's a bit of a PITA but usually I only have to do it once per session

I get this problem when I'm using my G2 in the dark. Turning on a bright fluorescent light fixes the tracking issue for me, maybe it'll fix yours too.

Thanks for your reply's guys!
I am using WMR; I have no choice I believe. Pretty new with vr and this stuff installed itself, starts with the game, so, thats it as far as my knowledge goes.

I did try to reset my position and it worked, but when I -without going out of the game- took another car; it was back again.
Did not try the light though and for now I have none lying around, but I will try that one asap!

Just another question that comes to mind (and was very present when I was looking now).
I started the game, drove a few laps and "render stats" were giving 90 fps (I have set max fps to 91) and the "PHY_LAT" was very low (low is better, right?).
There is one spot on the track that makes the fps drop for a moment.
Starting the game again, without altering settings or something like that, nothing in the background: dropping fps on 15 spots on the track and the LAT building up very fast.

I have noticed this before; running smooth, being "out of the car" or even out of the game and it runs like crap again. Sometimes it does run like crap from the very beginning; it seems to have two "settings"........run smooth, run like crap.
I played around with alt-tab and so on; nothing makes it better.
GPU usage is the same in both cases just like all the other things I can see in afterburner; no difference there either.

Do you guys happen to know if there is something up with that?

When I reset my position in WMR, I prefer to have the headset worn on my head before clicking the "center" button. Maybe it's coincidental, but I don't think I've had any tracking errors since I've started doing that (as opposed to centering the view with the headset held in front of you, as per Microsoft's instructions).

I'm not too familiar with PHY LAT, but I'm guessing it's dealing with the physics? In that case, I'd guess that your CPU is responsible for the rapidly climbing LAT. Are you still using the i5-3570 (from what I've read in your previous thread)?

Do you have Custom Shaders Patch and its exclusive app, "CSP Render Stats"? If not, I'd highly encourage you get CSP and the app. I'm not sure which version of CSP this app was first made available, but I know that it's available on versions 1.74 and up. It wasn't present on ver. 1.69 when I tried it out last night.

I like CSP Render Stats especially because it overlays the CPU and GPU frame time graphs on top of each other. (It's also free). The graph overlay is very helpful in real-time diagnostics. For example, I've been using it to determine why I'm stuttering in certain corners. I can see that the CPU frametime spikes a half-second before the GPU frametime does too. This leads me to believe that I'm bottlenecked by the CPU at those certain corners.

Give it a shot and I think you'll be able to clearly determine the root cause of your stutters.

If your CPU is indeed your limiting factor, you ought to check this post out for some very helpful tips: https://www.racedepartment.com/threads/is-assetto-corsa-cpu-heavy.200056/post-3361178

As @justwannadl said, the lighting is super important, but also try and make sure it's as diffuse as possible. I found mine didn't play nice with spot lights, but is very happy with a simple shaded centre light in my office

Funnily enough I found the same thing. I figured it was because from my lap most of my surroundings are obscured by the wheel.

Yes it's a plain count of the number of times physics calculations finished late (which delays the whole game, because the physics runs at a fixed "framerate")

Thank you all for your input guys and sorry for again a late reply; real life bothers me a lot lately.

Anyway; I did the trick in wmr and that one does work now (there seemed to be two ways to do it, I thought at first and didn't have the proper one it seemed) and I'm pretty happy with that.

As for the stuttering; I wasn't using any shader as I thought that would be to heavy.
Wel, I did check that one that sets it and choose "default" and uncheck everything underneath that. If I don't check the first box, I can't see my shifting lights.
I did notice, that when the car does move with my head, the stuttering is less so thats a thing.
But what can I do, right? Just lower the settings again and that's it; I have to deal with it.

Saving up for upgrades:
i5 3570 stock
8 Gb ram 1600 Mhz
cheapest mainboard
GTX 1070 was updated a year ago

Is going to be:
i5 11400 or 12400
16 Gb ram 3200Mhz
better mobo
later on, after way more saving, there must come a RTX 3070 TI
