Openxr now works with vam

[itscard0man]

I am not getting this to work, after copying .dll file intoplugin folder

 

[Plunty]

Hi All, I got OpenComposite working wonderfully and thought I'd quickly share how:

Machine specs:
CPU - AMD Ryzen 7 5800x3D
GPU - AMD Radeon 7900 XTX with driver 23.7.2
Headset: HP Reverb G2 using the controllers that came with the headset

If in the past you ever tried the vrperfkit and you still have the dxgi.dll file in the VAM directory, go ahead and rename it to something like dxgi_nonactive.dll to disable it.

Also, if at some point you've tried the fsr mod, go into VAM/VaM_Data/Plugins, find the openvr_api.dll and if it's the fsr mod version of the file, rename it to be openvr_api_openfsr.dll to disable it. Normally you would then re-enable the default VAM openvr_api.dll file, but in this case do not, keep reading below.

@miketruck69 mentioned in a prior reply about the skyrim mod version of openvr_api.dll. This particular version has a few extra parameters that it accepts, and important for Reverb G2 owners, are these:
leftDeadZoneSize = 0.2
rightDeadZoneSize = 0.2

Download the skyrim dll file and place it into VAM/VaM_Data/Plugins/openvr_api.dll.
Also, in the VAM folder, create a blank text document called opencomposite.ini and place the left/right "DeadZoneSize" lines in it as shown above.

Download the "OpenComposite Runtime Switcher (OpenXR)" app. When you launch it, click the button "Switch to OpenComposite".

Launch VAM by using the VaM_Updater.exe, and then clicking on the "Launch VR" button. For me on the G2 headset sitting in the windows Cliffhouse, for some reason my G2 controllers are unable to "click" the "Launch VR" button, so I do that with the mouse.

Instead of the black Steam VR load screen, you'll be greeted with the white/blue triangles of the Windows Mixed-Reality Open XR launcher. For some reason, it usually does this three or four times in a row... as far as I can tell, that is normal or necessary for some reason, but after a few times, you'll find yourself in VAM, with fully functional controllers including joystick navigation (although, see note below).

This is a MASSIVE boost in performance. Night and day difference! Totally worth the trouble! You can tweak things on the open composite menu (F2 on your keyboard).

A note on the controllers: Most of the time, they work perfectly. Now and then the game will launch and the little dots that represent the controllers on the menus will be visible, but the buttons won't work to select anything. I am not sure exactly why it does this, but the best observation I have is that it may have something to do with pressing a button on the controller while the game is still launching into VR. If you encounter this issue, just try to "Launch VR" from the VaM_Updater.exe a few more times in a row, and I am betting after about five times or so, you will eventually discover that your controllers work exactly how they should.

Another note is that most other instructions would tell you to either use the skyrim mod's DLL file, or, to use Open Composite's DLL file, but not both of them together like I have done above. And technically they might be correct, but for the Reverb G2 controllers, I believe combining the two like above is a good scenario in order to fix the controller drift by using the "dead zone" updates that were added to the skyrim mod as an intermediary before that DLL passes control along to the OpenComposite DLL (at least that's how I am imaging it works). It's probably worth noting that, as shown above, I did NOT do an application-specific install of OpenComposite. Rather, I did an application-specific install of the skyrim DLL file, and a global enabling of OpenComposite, which can be easily turned off if needed for other games later.

It should also be noted that in the above configuration, I am not seeing an option for fixed-foveated rendering on the F2 menu in the open composite settings. I see this in other games, but perhaps the skyrim DLL has somehow disabled this, I am not sure. It would be nice to have if that can be figured out, but controllers that work (and also don't drift!) is more important.

I hope this helps someone. Let me know your experience with this approach if you try it.

Works for me... but I'm not getting any performance gain at all.

I think Openxr is running at a much high resolution because everything seems sharper?

 

[RexNemorensis]

No luck on mine using @Plunty 's method. It definitely got me further than any of my other attempts, but still no button response after VAM loads. I did notice however that it loads 10x faster as opposed to opening with steam. This would definintely be a game changer if I can manage to get the buttons to work. And I agree @emmaqq , everything looks much sharper. Colors seem a little richer as well

 

[kanjobanjo]

I wonder, do the people seeing a large performance gain have the steam HOME environment turned off in the steam VR settings, doing that gave me lots of performance in skyrim vr with my WMR headset, I also switched the giant microsoft cliff house environment into a super lightweight environment.... these 2 things will give you tons of VRAM back...

follow this guide and you will get GIGS of VRAM back...

Has anyone successfully managed to get this working on a Pimax headset? I have the 8KX, followed all the above instructions and VAM starts in desktop mode with the headset just displaying the static Pimax logo.

 

[genericlogin12]

I have a Pimax Crystal, and this works following Plunty's guide. IMO, the secret sauce was running Vamupdate.exe and launching VR that way, for some reason the vam openVr. bat file crashed.

 

[Bahamut]

I have the same problem, did you solved it?

also I have this error View attachment 241939

That specific error appear cause in the .bat file u have the option "-openvr". Delete it.

leave only: START "VaM" VaM.exe -vrmode

After u do that, just run the bat file normally.

"IF" after that u encounter problems like game being stuck loading forever before showing anything at all (happen with the G2 mostly)
follow these steps:

0) Be sure u applied the custom .dll posted few comments above.
1) Be sure u applied the opencomposite.ini with the deadzone fixes (only if u have a G2 or you keep sliding in game) .
2) Shut off the controllers.
3) Don't wear the headset (if u have the G2 u can wear it temporarly on the forehead but DON'T press win+y to redirect the displaying on the vr).
4) Run the game from the bat file (be sure u removed the -openvr option).
5) Wait the game to load until u start to see on the bottom corner of the game screen on the desktop, the vam buttons to toggle the menus.
6) Wear the VR.
7) If u have the G2 now press WIN+Y to redirect the video to the VR
8) Turn on the controllers.
9) Play.


To the other guy saying that removing the option openvr mean u're not using opencomposite at all, pretty sure u're wrong, cause even the opencomposite log file start dumping succesfully and in game u can see the fps increase aswell. (for my personal experience +10fps for vam, and between 10-20 more for other games).

Weirdly enough, I tried it again and the controls just worked pretty much as they should. Then next time I loaded it they didn't, then next time they did again. So not sure what's going on, but at least I have it usable if I just keep loading it.

The only control that wasn't bound was holding the A button to view targets, but that was fixable with KeyBindings - just bound Toggle Targets to the stick click (which I actually like better as a way of doing it I think).

Yes, this is still quite buggy.

I was able to get it to work as well on a
amd 9600x(5.5ghz) (stock aircool) 3090(2000mhz,10,000mhz), running cpu patch (ht or smt turned off, and the boot.config edits and set to 6 charmorph ect on SkinMeshPartDLL )Hp reverb g2
and actually im only running 1 stick of ddr5 6000 ram, main mobos getting repaired for m.2 pcie signal integrity at asus

i was getting like ave 75frames on 2 person medium load scenes, like cgs studio
not sure the render resolution, WMR set to optimize perf and auto scaling under windows VR, but supposed to be 2,160 x 2,160 pixels per eye

i did use the skyrim file, OpenComposite, and edit the bat for to
START "VaM" VaM.exe -vrmode
seemed to work as well as the vam_update->start vr

and also create the
opencomposite.ini in root
leftDeadZoneSize = 0.2
rightDeadZoneSize = 0.2



i need to work through the too large heap more, but turning off caching helped there.
and i havent had any glitches/crashes on it for the most part, worked mostly like steamvr but more frames if i recall.

Using @Plunty's guide, I managed to get this working with my Pimax Crystal OG. Except the default resolution is too high. I usually run 80% supersampling in Steam VR, so I added supersampleRatio=0.5 to the opencomposite.ini, but that didn't work either. I ended up setting this in Pimax Play to get the optimal resolution for my system.

I'm not getting any stick drift, so it seems like the deadzone settings work. However the controllers seem to be slightly higher and further away than they should be, it's like I need to offset the position. I'm using the Valve Index. Also I can't use the trackpad button to navigate in Virtamate. Does anyone have a solution for these quirks?

 

[thinoreos]

That is cool. Please let us know what else you find.

I'll provide a data point from my personal experience with controller, maybe it could be helpful to people:

My reverb g2 controller will only work if I turn it on *after* I started VaM.exe, otherwise it won't show up or work in game. And I have the drift too. My current solution is to disable all navigation in VaM setting so the drift won't move the camera, then bind Pan_X and Pan_Y in Keybindings plugin to to RightStickX and Y so I can move around in VR. I also bind Orbit_X to turn, but somehow the plugin won't allow trigger+joystick to be bound to one action, so I have to use shift+RightStickX to turn. It is somehow usable this way.

It would be great if Acid can add ability to bind trigger+stick* to an action, and add a real turn camera action, that way we can use RightStick to move along X and Z, trigger + StickY to move along Y, and trigger + StickX to turn.

Wait did I miss something? I thought the Keybindings plugin by Acid doesn't let you remap VR controls

Nope controls still broken on my pimax too with openComposite
