Launching DCS *MT* in VR (Steam)

[cfrag]

I read (in the very interesting MT thread) that supposedly, there should be a choice item to launch DCS as MT in VR. Unfortunately, for Steam users it seems that this option is currently unavailable (launching MT will not support my VR Headset - a Vive - and launch in Desktop theater mode instead):

Now, biggest likelihood: me be ham-fisted. What am I doing wrong, or is VR-MT slated for a later release?

 Thank you for any pointers.

my guess would be, that you have to start dcs.exe "manually" from bin_mt folder and add all your vr commands as arguments to the exe with windows. this is just an educated guess though.

That could be a possibility - thank you! Then again, Steam provides developers tools for packaging command lines exactly like this, and I'm doubtful that ED wouldn't have included that already if it was ready. So before I accidentally screw up my DCS install, I think I resign myself to awaiting some word from up high

I don't think so. I have the same

i think waiting for official clarification is a very valid approach. if you decide to tinker for yourself, you can just make a shortcut from the exe (in the bin_mt folder) and put that newly created shortcut on your desktop. all the command lines would go in the shortcut anyways, so if it does not work, you can simply delete the shortcut.
i could imagine that someone at ED just did not bother to put all combinations of different executables and different launch parameters in...

[Koziolek]

can it be that the Steam versions is not updated yet?

[dutchili]

Steam always launches ...\bin\dcs.exe, even if you use a shortcut to the other .exe

Help is needed from ED.

Here with my Valve Index performance in OpenXR, in MT, is a stuttering mess (even with motion smoothing on). Much worse that in non MT version. MT will be compatible with SteamVR?

I can’t launch The MT exe. In OpenXR or Steam VR Runtime,The screen freezes on loading similar to what happened when DCS added OpenXR natively.
 

I can run the MT exe. Fine in 2D…

I can also Launch/Run DCS in the Regular DCS exe.
Weird

I would love to see a Launch VR with Steam VR and mulithreading. Currently I can only launch VR within DCS and it launches Oculus VR for me without my FPS overlay.

The probably didn't add the option as it is broken. 

 

You can add "--force_steam_VR" to the command line of DCS launched from Steam, in title properties.

After checking, can you bump the thread I linked?

I have the standalone version and I renamed the bin-mt DCS.exe "DCS.exe --force_steam_VR" and it just breaks the executable. I feel like I'm doing something wrong

No, its doesnt work.

Its an issue. Now. DCS MT works ONLY in api OpenXR, not like single core version (without OpenXR as default).

Now only works " --force_enable_VR", not with "steam".

You mean "known issue". Please refer to some source?

You need to create shortcut with this param or the *.bat script.

I'm posting this as it might help some Pimax users here....I had forgot I had Pimax VR installed...I switched The Runtime in that App back to Steam VR and now at least I can use that runtime and MT.

Launch the MT preview with steam VR running in the background. Go to options (in DCS) and enable "Virtual reality headset". The game will relaunch and you'll see "Multithread preview" by the version number in the bottom right.

[Mike_CK]

Thank you for that answer. I couldn’t understand anything the other posters were saying:

jusr add $&/:; to your bin5/d4  file and back link your proton thruster so it enable the VXR validator subroutine…..”

jesus. Some of us don’t really know how computers work. Has to be a way to press buttons and make it go 

[MadogPL]

MT for me is ONLY working when from steam I choose MT version and then choosing the VR headset in settings. It's a laugh a bit as even launching mt/dcs.exe does runs normal dcs.exe.

It also screws up my controllers positions, so that's not very nice at all.

Waiting for a fix. Hopefully not 2 weeks.

I was hoping todays patch would remedy that, but it still does not work with Steam

[cfrag]

Same here. No MT launcher in Steam for VR. A bit disappointing as setting up the launcher isn't that difficult for the vendor, and can be done in the publishing front-end.

Well, I guess that's ED for you. Let's hope that they eventually get around to fixing this.

It’s not too hard to do it. Just get your VR apps up and ready to go. Go to steam (2d version) and select the MT option for DCS. Run it. When DCS opens, confirm it says multithreaded version in bottom right, go into options and click on “enable VR headset”. It will close and auto run the MT versus 

it’s a pain but worth it when I can now play VR in a MP PvP server and get a steady 45fps at 1.3bp. Used to be about 15-25

Has this at least been acknowledged as being a bug ? 
It´s been 2 patches since the MT update, and still no changes.

Agreed, not too hard. But decidedly inconvenient. I'm developing missions. That's done in flat. Then I test in VR. Switching already requires a re-start. If a switch now requires a double restart each time, this drives up the annoyance factor a lot - especially since it's quite trivial for ED to provide this option (it requires two clicks in Steampipe, the developer front-end for Steam).

Unfortunately, I have not seen anything from ED, not even a 'reported' tag. Let's hope that one good day in the future a developer happens by, looks at this issue, and is kind-heartened enough to care and acknowledge it. It's the little things, I know.

[Eugel]

Well I guess it´s one way to get people away from Steam ...
