Now MT version is VR must-have! Eliminated my stuttering issue!

[kerlcat]

Kindly remind that the outcome is depending on specific hardware. You may not see the improvement I just saw which is pretty amazing!

You might wanna try if you are still with previous stable one like me. 

In short, this MT version just eliminated my previous stuttering issue. Was occuring each 4-5 sec. Deal killer to VR experince even my previous fps is acceptable. 

And also see ~10-20% of fps increase. Not that big. But good enough for a SW upgrade. My setting is with many highs and visible range ultra, cloud also ultra.

Yeah running MT version in VR is especially a no brainer - performance benefit is nice and hopefully they will continue to improve upon it as time moves on.

Agree! Now waiting for ED making this preview to stable (seems still some reliability issue)... AND Vulcan is on horizon as next big milestone.

It moved to stable today right?

Yes, the stable version just released in case you didn't realize! https://www.digitalcombatsimulator.com/en/news/changelog/stable/2.8.4.39731/

But pls notice that it means ST stable with all improvement since Dec. And MT is still same as preview which you might be using as Beta. 

So for me, MT preview version today (as part of Stable version release today), is way better than my previous Stable version updated in last Dec.

Glad to hear of your success. I've been finding the opposite. If I run MT - I seem to be getting stutters - whereas on single thread the experience seems to be much smoother. (I am using OpenXR motion reprojection). 

Thankfully ST is still available to use while they iron out these issues with MT.

Sorry to hear your opposite experince. Hard to believe it's caused by MT itself which shall be designed to remove those performance bottleneck. Hope you could get it solved soon with ED 's help by submitting your bug. BTW I don't use any reprojection. Fps is about 50-90 now with 3090.

My situation is exactly the same as yours, and I'm glad that ST mode still allows me to play happily.(I am using OpenXR without motion reprojection)

MT is definitively an improvement, it needs a little more performances and fine tuning but is on the right path.

I figured my rig is a little GPU biased, there is little more to come from my GPU but the CPU could be made to work harder, also the whole package could put less load on our PCs once fine tuned. Good one.

What softwear are you using to get the ingame performance monitoring data in the above screen shot?

Unless there is big difference driven by 3D V-cache in solving stuttering, wonder something has to be wrong with your setting or SW. I am using Oculus(OpenXR) to drive pico4 through MT version. It’s smooth like butter.

How do you run MT through Oculus? Mine always defaults to steam.

Try this, but I cannot guarantee this works for you. Good luck.

1. Ensure you have Oculus SW installed. No need to open; and set OpenXR on under Experimental;

2. Set “HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenXR\1\ActiveRuntime" to null. Need to repeat this every time after you opened SteamVR;

3. Create a .bat file to start DCS MT via VD.

How do you go about creating the batch file?

It's just a text file with a .cmd extension. The contents of the text file should read (with your specific path indicated - mine happens to be G)

"G:\DCS World\bin-mt\DCS.exe" --force_enable_VR --force_OpenXR

FYI. Here is mine. Start DCS MT via VD for pico4. Text file with below content and change extension to ".bat". 

"C:\Program Files\Virtual Desktop Streamer\VirtualDesktop.Streamer.exe" "C:\Program Files\Eagle Dynamics\DCS World\bin-MT\DCS.exe"

Thanks. Yours is better w/o VD. I tried it w/ VD but the extensions won't work in below 2 formats. 

opt1. "C:\Program Files\Virtual Desktop Streamer\VirtualDesktop.Streamer.exe" "C:\Program Files\Eagle Dynamics\DCS World\bin-MT\DCS.exe" --force_enable_VR --force_OpenXR

opt2. "C:\Program Files\Virtual Desktop Streamer\VirtualDesktop.Streamer.exe" "C:\Program Files\Eagle Dynamics\DCS World\bin-MT\DCS.exe --force_enable_VR --force_OpenXR"

Thanks,  I copied and adjusted the drives and directory for my system.  I am I wrong in thinking that by running this batch file that I should only need to put on the PICO headset and I'd be in the VR hanger?

You are welcome. Yes, simple like: 1. switch on VD on PC, 2. put your headset on and also open VD/connect to PC, 3. run .bat... then you are expected to be hanger.

I don't know what I'm doing wrong but when I run VD on Oculus runtime ( by setting active runtime to null and confirmed by VD overlay)  I cannot open OpenXR toolkit

1. Ensure you have Oculus SW installed. What Oculus SW do you mean?

2. set OpenXR on under Experimental. Do you mean Turbo mode?

[kerlcat]

@Koziolek I don't use toolkit. So would have to defer to others to help you on that. 

1. Oculus software: I meant official Oculus client downloaded from Oculus website VR Meta Quest Help Center | Meta Store. It's used for portal/equipment management of Rift S or Quest2 headset etc. 

2. The switch should be in "Setting"-"General"-"OpenXR Runtime". Ignore "experimental" which was incorrect due to my terrible memory. 

Hope this clarified your questions.
