Need help
I recently encountered a problem with VR. When i launch vr mode I can only see black screen. When mirror to desktop i can see game works fine, but in goggles there is only black screen.

You have to make sure that Steam VR is running and recognized your headset. If the Steam VR dashboard is visable on the goggles then VaM should be displayed as well. If your glasses only support a certain Hz then make sure the VR Software and Steam VR is set up correctly.
Never had problem before with steamvr. I solved it by launching VR directly through oculus without steamvr
the closer i get to the model the lower my fps gets and that's a real problem for VR. when the whole model is in vision i get 80 fps, when i'm so close that i can only see her face i get 35 fps. is there any fix for this?

Yes, the problem is the hair, as mentioned above. But the only solutions were either removing all hair from the model (no, thank you), or running the game through Virtual Desktop.
I used to have the same problem when running with ALVR, which requires SteamVR. Using VD this isn't a problem. If you use airlink, try to run without SteamVR, there is a slight chance that this will fix it. Also, try using Givemefps plugin and reducing hair multiplier. Maybe it can work for you (for me it didn't)
Dang i didn't think the hair was the problem... Well at least it's something i can fix, i was afraid it would be something on the engine or driver level. Thanks for letting me know. I'll test the differences between VD, Air link and Stream VR tomorrow.
You can also try using a plugin like

(link to plugin page on VaM hub) in order to reduce hair quality automatically in all scenes. Just lowering the number of individual strands and making the existing ones thicker can make a world of difference.

You can also set the hair pieces in the "Look" tab to "fast".
I cannot recommend Givemefps because it resets all hair assets physics to 16 which will look really bad if you use pubic or other hair assets like brows.
Use OpenVR with FSR2 and lower hair pieces quality to a minimum and or to personal liking. Reducing hair lenght also boosts fps.
If you use a single dim light (from bodylanguage's watchme plugin for example) and toggle off all other light resource (within watchme with one click), you will not really see a difference in hair quality but your fps should be significantly better than before.
Mine jumped from 15-20ish on heavy scenes to 30 and higher with a 1080ti.
i'm not a fan of GiveMeFPS either.
i already made my own minimum viable light subscene with 2 directional pixel lights.
i thought the hair shader made a huge visual difference, but i guess the lack of shadows is okay if you don't do an A-B comparison all the time.
i don't know how i didn't find this sooner, my 3070 runs at 45 fps (no spaceswap lock) with hair and being close to the character, and 120 fps with no hair at any distance, with all plugins turned off. i have no idea how this is acceptable, i would be pretty mad if i paid for VAM.
...i just found out it's not even the physics that are so taxing, it's just the hair renderer. turning hair sim on and off makes almost no difference.

Can you help me do these steps?
Do you use Virtual Desktop? How do you launch the game for it to run with OpenVR? I tried to use that VRperfkit, but the game becomes so stuttery that it makes my eyes hurt in 30 seconds. And the foveated rendering plugin simply won't work
That 'watchme' is that CheesyPluginSuite feature? I can't find that option to remove light resources

I dont use virtual desktop. Iam closing all unnesesary apps after Steam VR is open (I also close steam), VaM Process is set to realtime and I force the VaM process to NOT use all cores. I ussually take away 4-5 out of 24. (this should counter alot of short stutters but not all!)
For watchme, add the body language plugin to one of your characters. Be aware it has auto handjob and stuff enabled by default so it could break timeline animations. Deactivate all of them under fillmeup/forces tab you dont want to mess up timeline animations. Also the shake chance under "readmylips"sometimes do weird shit to the character on animations, I also deactivated those.
Then go to watchme and hit "install focus on me". You can also add watch triggers like eyes, head and so on so the character with bodylanguage will react if you look at those triggers.
After hitting "install", "lightmeup" will apear in your vam vr menu. Hit the button and just enable C for center light. Then go to sessionplugins/lightme up and set your center light range and strength to your liking and set center light to force pixel.
Deavtivating all scene lights with one click should be on the upper right somewhere.
Then safe just body language as plugin preset.
Now, everytime you add body language and activate lightmeup, your light settings should carry over. Body language is getting updated very often lately so be aware to do this everytime you update the plugin.
For OpenVR, you just have to download the FSR mod from github I believe and copy it you Vam_Data/Plugins

I have tweaked abit around in the config but the standard 0.77 scale is good enough. You can go up to 0.85 but anything beyond doesnt make any difference just worsen the performance, atleast for me.
So set everything up until your SteamVR environment is visable on the VR goggles and then just launch the "VaM (OpenVR).bat" and vam loads up like normally but with FSR2 enabled. You can switch to the Nvidia upscaling with a hotkey but it looks super bad compared to fsr.

Thats because when any hair asset is set to "quality", the shadows will apply to every hair layer.
Try disabling ALL light sources and set all hair pieces to fast just for a test and then use the single light from watchme's lightmeup session plugin (set to pixel light and not on standard range).

Thank you for the thourough explanation. I managed to make lightmeup work. I was looking for a plugin to disable all light sources easily for quite some time to make customization easier. Yay! Thanks!. Although the lights are not making a huge difference in performance...

Combine it with fsr and lower hair asset quality. You will notice a difference.

How do I lower hair asset quality? Is it that shader quality that I need to change to fast? Or just reducing the multipler/curve or some other setting that I missed?
I'm not sure fsr will make any difference, because I already use an upscaler. VD uses snapdragon super resolution, which is like fsr but runs on the quest. It's good because it fixes the image after it has been encoded and sent through the network.
The problem with SteamVR is that people say that running with it kills a little bit of performance... Also, I'm having no luck with it. My controllers aren't showing up in VaM (works fine running Half Life Alyx)
Which streamer do you use: Airlink, ALVR, SteamLink?
