Pico 4: how to set it up for DCS?

@VR Flight Guy in PJ Pants It's right there in the numbers of fpsVR: 120% ss resolution only. This is pretty low. Most people use 150% and more for sharper image quality. If it's enough for you, why not?

Actually I was just illustrating the point that somebody here and elsewhere are simply irresponsible for what they are typing. The screenshots can be misleading. Actually, the screenshot is not the whole picture. The rest of the flight went mostly at 45 fps....

So, if my understand is correct, I can make SteamVR soaring in terms of frame rate. Any guide would be very much appreciated.

BTW, I am still waiting for the updated 4090 setup guide...

Thanks in advanced.

I need so OpenXR for XRNS...

I guess DLSS is only available to NVIDIA cards and is it OpenXR?

Also, I notice that there are discrepancies between VD's Performance Overlay vs fpsVR and DCS's own frame rate display. The former shows double the frame rate over the others, most of the time.

I'm trying to figure out the "and is it OpenXR" addition to your DLSS/NVIDIA question?

This is just the start of new troubles (of which I'll be pretty happy to have and maybe even contribute at solving)

Please, please do not dig too deep into this one. I was just kidding.

[RealDCSpilot]

There were discussions that ED will never implement DLSS and stuff. But well, it does make so much sense. With OpenXR it's the same. It wouldn't make sense to not implement it and get rid of the old VR APIs.

[VR Flight Guy in PJ Pants]

Unless this were BMS....

BTW, I turned off ASW on VD and it runs much better...most of the case. But I just find something amazing, may be it is the engine or lack of ray tracing there of, I am going to post it somewhere else.

Heads up if you're using VD on Pico 4. Latest firmware breaks VD.

Alright, got my new machine on friday, was pretty busy installing and migrating all the stuff...
When i started DCS for the first time, i got shivers down my spine. Never seen this image quality and performance in VR in DCS.
3840x3840 per eye resolution, DCS settings on ultra but without any AntiAliasing. It's mind blowing.

Still has no firmware update...I can wait and I am then not sure if I were lucky or not. Yes, turn off all AA is a big help.

OK guys, I've bought a Pico 4 (again), assuming that it's now possible to get it up and running.

 

I've had DCS running with SteamVR, no problems, by both Neo's streaming assistant and Virtual Desktop.

 

I've then installed OpenXR toolkit, done the usual kind of config, e.g. go into SteamVR and set that to OpenXR, but I've not got DCS successfully running OpenXR to my Pico, such that I can then enable the usual OpenXR goodies.

 

Would someone please be kind enough to talk me through the step by step elements to enable OpenXR with Pico 4

I didn't see you mention loading OpenComposite dlls and replacing openvr_api.dll - do some Google searching.

[Lange_666]

@whitav8 really? Next time you ask a question my finger will the only thing you gonna get.

I've found the 32/64 versions of OpenVR, will give that a try tomorrow, thanks.

That resolved it, thanks.  I'd missed the step of replacing OpenVR_API.dll.

 

Just had DCS running via OpenXR using Virtual Desktop (wifi) and Streaming Assistant (both USB connected and wifi).

WD definitely looked better and also ran with fewer micro-stutters.

What's the current state of play on USB connectivity for Virtual Desktop?

I've found an ADB command and tried that, but that doesn't appear to have worked.  Is there a new version?  This certainly used to be possible as I've had it working with the previous Pico 4

[VR Flight Guy in PJ Pants]

I am told USB connection on VD is not possible, because the author does not have access to the low-level USB API.

As mentioned, it certainly used to work when the Pico was first launched.  No idea if a software update has killed that.

[VR Flight Guy in PJ Pants]

The USB tethering method worked with the risk of BSoD. Definitely USB would be the best for connection speed, but then, we either take the SA or VD, which the latter still gives the best overall. That's all I can say.

I've found a guide online on how to get USBC working with VD:

Unfortunately I get an error message on running the terminal command...

Hmm.

No wonder PC-VR is no where near any mass adoption. Just look at all the steps required above... all because they chose not to provide a native display port connection for the PC.

Can't argue with that.

On a positive note, I'm now happy with the Pico4 using Virtual Desktop, currently on wifi.  I'd still like to use USB, but I now have a degree of confidence that it'll get there and this time won't be returning the Pico.

My thanks to those who've helped, much appreciated.

 

I'll be retiring my Rift S as the Pico really does have massively better visuals and DCS looks utterly fabulous.

They want to make it PC-less and appeal to a new reach, far bigger than the PCVR market: Facebookers and Tiktokers.

 

 

[Mr_sukebe]

OK, got it.  Here's a walkthrough on setting up the USB connection for Virtual desktop:

Again, it's a bit convoluted, but as I'm currently at 17,000' over the pacific in an F18 using VD/OpenXR via USB, I'm MUCH happier.

 

and 20 mins later, BSOD.  Hmmmmmmm

That's why this UTuber switched to Ethernet later.
