Assetto Corsa in VRPC

[Masscot]

@Masscot does yours work with OpenComposite_acs (acs.exe)?

Yes, that's what mine says.

 

[Masscot]

OK, having had a play with the toolkit menus I can confirm that everything seems to be working, even foveation.
I now know why I changed the menu overlay from ctrl+down, it's because that's what I use to fly around in VR.
The toolkit menu is one of the most frustrating UIs I've ever used. Why the hell is simple mouse navigation not possible?
It's so counterintuitive it's far too east to accidently break a previous setting without any way to revert.
Hateful, hateful UI.

To those who still cannot activate the overlay UI, try unticking fullscreen in AC video options. That's the only thing I can think of.

So, if I understand correctly, you can access toolkit in game using Oasis, like we used to with OpenComposite.

Yes, using the 'down' arrow with my ctrl modifier. The overlay settings menu appears exactly like it did with WMR (and is just as horrible to navigate).
I really need to change activation (and navigation) away from the arrow keys because at the moment those navigate the menus but also make my VR viewpoint fly around if I'm in F7 cam.

It is my turn to be puzzled, as I cannot get that menu to appear in AC using Oasis.
Probably some setting somewhere, at least now, I know it can be done.
It is probably not a setting in AC, as the menu does not appear in any other games either, it used to with WMR, so not specific to AC.
I know it works because I can see it in AC Evo, which is different from all other of my games as it runs OpenXR native. So it by pass OpenVR in Steam VR.
Something in my SteamVR setup is blocking that menu for me.
As mentioned before: The plot thickens.

Hey all, wondering if there is a friendly soul out there who can help:

I am running Assetto Corsa using Virtual Desktop + OpenVR + Opencomposite (mandatory) + OpenXR Toolkit and the companion. I found it gave me like 30fps extra over running it through SteamVR and Airlink, which was a HUGE surprise.

Question 1:

Is this the right thing to do in 2025? Is there any new tidbits I've missed?


Question 2:

The only downside I have in running it in (actual) OpenVR is that the little yellow mouse dot in the pre race menu when you are sitting in the car, the mouse isn't able to cover all of the screen. There is like an invisible wall. Using the Quest 3 handcontroller does cover the whole screen, but it sometimes takes over the dot sometimes not. It's very frustrating. Often I have to hit ALT+F4 at the end of the race just to be able to get back into content manager.

I've tried a myriad of options in Assetto-> Video, checking fullscreen on and off, fix res automatically, changing the default to my screen, etc. Nothing helps.

Quest 3
5070Ti
Assetto Video set to OpenVR and custom resolution at 3000x3000x0
My actual pc screen is a 1920x1080 display
I don't run passthrough or mixed reality
I have all settings maxed out in Assetto and the in game renderer shows 112 fps, so performance isn't an issue

Very weird indeed. I can't see anything obvious in your SteamVR settings.
It'll be something simple somewhere and you'll kick yourself when you find it.

My Oasis conclusions so far:

• OpenXR toolkit seems to work fine (hooray!)
• Tracking seems normal
• Performance does seem to be down slightly compared to what I've been used to with WMR, but that could be any of a whole host of variables and not because of Oasis
• I will never miss those pointlessly annoying WMR splash screens or that cliff house environment with the tweeting birds
• My audio no longer gets hijacked by the headset on starting VR, only Crew Chief comes through the G2 headphones now, as intended. Main audio gets piped through my amp automatically.
• Everything just seems slicker and quicker with less faff compared to the WMR bloat.

Who would have thought that Microsoft actively working to brick our WMR headsets would have eventually led to a much better experience thanks to the tireless work of one genius coder?
Microsoft actually did us all a favour with their scorched earth WMR policy.

I think I now why, I am on 24H2 and you are on 23H2.

OpenXR tools is not compatible with my OS

So 24H2 not only kills WMR, it also kills OpenXR?
Goddamn.
Seems like I have to keep trying to block 24H2 then, just when I was about to allow it.
That is terrible news. The OpenXR toolkit makes a HUGE difference to performance.

@Cote Dazur maybe ask the question in the Steam forum I linked to recently, maybe the dev will clarify what the issue is?

OpenXR tools still works for me, if I do not allow it in Steam VR I can see a difference, it is access to the OpenXR toolkit ingame app that I do not have access to.
Except for AC Evo, where I can access everything, probably because it runs native on OpenXR.

So it's impossible for you to make changes to the OpenXR Tools settings in AC now?
But existing settings work?
Are they global settings, or per-game?
Can you alter the settings in AC Evo (where the menu overlap appears fine) and then they'd translate to AC?

not possible now.

I believe so, but I am not able to verify, all I know is that it looks and run better with OpenXR toolkit layer API on in SteamVR.

I don't know, with WMR they were per game settings, I assume they still are, but not sure.

 

[Pekkahe]

Guys, are you now mixing OpenXR tools and OpenXR toolkit. Former works with WMR and latter is the tool that Mbuccia made for opencomposite.

 

[Steve Hayward]

Right, so I have been catching up with the posts on this now I am around.
I have exactly the same settings as you and cannot see the toolkit menu.
Have tried to replicate mascots findings and settings, no change.
If I go off full screen in CM I get the 60fps as I always did.
I do get small micro judders at times.
Toolkit is definitely working as before in terms of graphics.
My conclusions are that I was happy with the settings I no longer have access to so I can ignore that.
The only thing I need to change is the pixel density which I can do on steam anyway. I also rediscovered the per game
slider which I had set to 150% before I used open composite and the toolkit so I have found my stutter for sure.
Did the oasis update.
Oh, and just to confuse things, I am still on 23H2.
Just happy it is still working and for now I'll work around the small stuff.

Very weird that I can see the menu and you two cannot.
Maybe try turning off both modifiers and pressing every single key in sequence?

 

[Pekkahe]

From toolkit ui press Open log file and at bottom find circled entry. Maybe this will help.

In my case the key sequence is not the issue since CTRL + arrow down works for Evo.
