Guides How to launch without SteamVR (Performance Increase)

[Kawum]

Maybe there is something wrong with VirtualDesktop. I just downloaded it. When I right click its icon, The "Launch Game" selection is gray.

Bit late however, launch game section will only be active from VR, so when connected to VD desktop from quest. Just create a .bat with command "[VD path]\VirtualDesktop.Streamer.exe" "[VAM path]\VaM.exe" Stick it on destop, point the pointer,clicky da fingers and presto. Vam without steam.

When i try this with the virtual desktop method, the game start but its very jittery and unplayable.
Any idea what could cause this?

Is VAM normally like that for you even without this method? If so you'll need to adjust your graphics settings

I haven't played VAM in VR in a while. When I last played, I could hit the 90 fps max of my headset in a simple scene. Months later, I tried launching VR mode again but no matter what I do I can't seem to get over 30 fps even in an empty scene. This is using a clean install a VAM with no additional vars. Vsync is disabled ingame and in the NVIDIA control panel, I don't have a frame rate limit set in the control panel either. I'm completely at a lost at what could be causing this as it only happens with VAM, every other games runs fine. This is through Oculus. If I launch through SteamVR, I get about 50 fps but it is unstable.

Edit: I also have ASW disabled in the Oculus debug tool.

Might be a deep underlying problem that's not VAM related, have you tried other VR games or apps and are they the same? Just taking a first guess here

Managed to fix it. For some reason ASW was still activating in VAM but not in other games despite being disabled in the debug tool. I confirmed this using the Oculus performance profiler. I had to download and use OculusTrayTool to disable it in VAM.

Thanks Thinoreos. Very easy to follow. I jump between opencomposite vdxr + openxr toolkit and just the VD batfile. I've a question. I read someone mention that with the VD batfile method, I can use VR Mod App to run foveated or upscaler stuff that's in the VRPerfKit. I've experimented a long time but don't think they work unless I go the opencomposite method. Curious of your opinion on this. I'd prefer not to use VDXR since my pointers start pointing in a little awkward angle. The way I know that it works on VDXR is that it can go into debug mode whereas with VR Mod App, I've no way to tell that the settings are running since the debug mode doesn't appear in VaM.

Another question is - do you also use the VD SSW setting with and set double FPS? This is another topic I read from the community somewhere that this setting could give extra FPS.

That's great! I personally don't use open composite +vdxr for this because the controls with Opencomposite are messed up, and like you said the angles are wrong. There's no way to adjust the settings from within open composite as the dev doesn't support it for this too. The performance gains are also similar between running in Oculus mode & running with Opencomposite, so there's really no point IMO.

SSW doesn't "double" your fps, it interpolates it so it makes it look like it's double the fps for half the performance. You can try it for yourself, for me it looks pretty terrible and jelly like, but for those with lower specs it can help with performance at the cost of visual jigglys, but again try it for yourself!

I'm also having the jitter issues while using Virtual Desktop with a Quest 2. The framerate is all over the place and the head tracking is snapping and rubberbanding back and forth to a nauseating degree. It doesn't do this while using the native AirLink connection.

Has anyone been able to figure this out?

Is your SteamVR on? Is ASW on?

I fixed the issue by deleting the dxgi.dll file that came with the vrperfkit (VR Performance Toolkit) for anyone suffering the same jittering / stuttering problem.

Quest 3 (PCVR link cable) + Vive trackers. Launching steamVR seems mandatory for my trackers to be recognized. Anyway to bypass this restriction? I would love to gain some more FPS in VR, I used to have a decent experience when I was not using steamVR, but now that I have the trackers...

 

[cheeeeellin]

I had this working perfectly (first option). But now when I open the .bat it just opens it in Note pad and does nothing. Any thoughts on what could be the issue?

Sorry not through this method, but you could use the VR perf kit method for SteamVR to help performance a bit

Redo the whole .bat file, if still giving issues might be a windows thing for you. Can check around like here: https://superuser.com/questions/1415142/batch-file-will-not-run-only-opens-notepad

I have the same problem but on an HP Reverb G2. I have the VD desktop app but when trying to launch it within the G2 it will open Steam VR.

It does work on my Quest 2 though.

Virtual Desktop for WMR headsets is only available through Steam. But Method #1 says to use the non-SteamVR version of VD?
Where can I get the non-SteamVR version of VD for WMR headsets?

Method 1 doesn't work for WMR headsets, try method 3

I followed instructions, but for whatever reason, when I save, it doesn't turn into a .bat file. yes I put the extension. When I go to double click it just opens the text back up. It's staying a text file.**Update** I was able to get it to work after a few retries. I think the order might matter? the last attempt I created the file but waited to name it, until after I made the command land, and did save as. Then named it with .bat at the end. That seemed to have worked. When saving as, I also changed to all file type.

omg. This was my issue too. I completely forgot add that a while ago. This fixed my VD performance.

 

[HunterDadHD]

Here is an alternative method that might fix issues like this if any suggestions here didn't fix it

Vam with VR Desktop is either 1fps or no controllers (video)

So I ran into this problem with VAM with my Quest 3 and Virtual Desktop a while ago that showed up out of nowhere, and after several updates it still persists, to the point where I cannot use vam wirelessly anymore.. I really hope someone can help me with this because playing it via wired link...

Tried this with Oculus quest 3 and Meta quest link-no perfomance difference whatsoever, unfortunate

If you're using Link cable make sure you're launching with Oculus runtime, and compare it with SteamVR to see the difference

thinoreos submitted a new resource:

How to launch without SteamVR (Performance Increase) - How to increase VR performance by launching without SteamVR



Read more about this resource...is there a video totorial because ive read this nearly 50 times yet still i have no idea what im doing, and i have grown to hate steam so badly i wish i had access to nuke because id blowthem up.

I guess there is something with how VAM works on my system in VR mode,bcs its literally a fresh install,and it works fine in desktop mode.
I tired Half Life Alyx,to test how it will works compared to VAM. On max settings it works perfectly fine,havent noticed any statters or lags.Also image looks alot better than VAM.

My guy you are comparing Half Life Alyx, the MOST optimized game in all of VR to ... VAM? ?

(Hopefully VAM 2 runs a lot better in VR)

But 3-4 times fps difference in VAM(compared do desktop version) is abit too much as for me,esp looking at image quality
