Yes. It was always off for me, but switched on before first testing the MT version (tried to act as written in the MT FAQ), but experienced bad stutter with MT. After that I read in another topic that hyperthreading was a bad idea for other users as well, so I tried to switch it OFF again, which indeed made MT version much better than before.

Curious if after switching it ON, you performed a power cycle?  Not simply a reboot.

while in VR (OpenXR) it becomes CPU bottlenecked on the MAIN THREAD (not the rendering thread) in a simple SP mission?!

A lot of people (including myself) are having that problem in VR, looking at the amount of threads that pop up. I’m sure it will get fixed. It’s still very early days after all and there are also limits to what DX11 can do I imagine.

I hope we won’t have to wait too long for Vulkan…

[St4rgun]

The easiest reproduction is to go into main menu in VR. As long as I get solid 90 fps in ST version and 75 fps with CPU bottleneck (main thread) with the MT version then not even starting any mission is neccessary.

This was mostly an experiment in how fast can i get it to go and still have a reasonable quality picture.  So sad but true that there is such a trade-off between speed and quality.  I to have high hopes for Vulcan (it really helped with X-Plane, but took them a long time to change over).  I also hope to see more improvement with MT over the next few months.  Of course the developers will just add more features and will just slow everything down again.  The usual see saw in programming and sims. Just for fun I cranked up all DCS in game setting to max, dropped FPS to 30 to 60 or so in VR.

Thanks for this I have followed your settings right through and Im now getting 40-45 fps....... Smooth to fly the Apache... but Lots of fine tuning on graphics required as I am only running a RTX 2060Super. Interesting very few frame drops.

Has anyone got a Nvida settings page I can try out, based on the above please??

Awesome patch fix! Thanks for getting it out there!

I still haveproblems with the cockpits of the Mi-24P and the KA-50 III. in the MI-24P there is no english cockpit available for me and in the KA-50 III the ABRIS AMMS is also always in russian even though the rest of the cockpit is in english. With both modules in "english cockpit" chosen in the special tab

This is what you are looking for in the Ka-50, I guess?

I dont have oculus myself sorry but someone who does said this 

"MT works via native client with both AirLink and VD. Make sure you launch dcs via VD with "Launch Game..." feature"

FYI:

Changing ActiveRuntime in Registry to None re-enabled OculusVR for Pico 4 in MT.

(Set HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenXR\1\ActiveRuntime to None)

Finally got rid of SteamVR and the problems with being possisoned at the wrong hight. No flickering/blinking at startup. Also when ending DCS I'm back in Windows and not SteamVR.

Obviously it's not OpenXR, but for me Oculus works better that SteamVR/OpenXR.

It is great! But too late, I have sold my Pico4...

I'm playing around with Process Lasso... is there a magic number of cores I should assign to DCS.exe on a Ryzen 5600X 6 core?

I was thinking of buying a pico 4 for a play I use a G2 at the moment, any reason you have moved on ?

[crispy12]

I have the Pimax 8KX, Reverb G2, Quest 2 and Pico 4

And out of all these... I think Pico 4 is the best (when it works), and G2 is second
Quest 2 is the most stable and easiest to run, but the FOV and Fresnel lenses are worse...

For me it's the Pico 4 which is the easiest to run, also it is very stable.  I have G2, Pimax 8KX, Pico4 and Quest 2. Quest 2 would probably be just as easy and stable as Pico 4, but since the visuals is so bad compared to the Pico4, I never use the Q2. Pimax 8KX is collecting dust. Same with the G2 now after I got my RTX 4090, the Pico4 gives me the best visuals. 

"When it works" statement about your Pico 4 I really don't understand. It just works.

I have both G2 and Pico 4. The Pico 4 gives me the best visuals and the best comfort. It is so light on the head. Be aware that I run it with a RTX 4090 and an Intel I9 13900K. Before I had a an Intel I9 9900K and RTX 3090. Then I prefered the visuals I could get from the G2. Anyway, I never use my G2 anymore, but I am keeping it as a "backup" just in case.

Thanks! I will check it out   Before the MT update I had with the Pico4  8-10 fps more when using the Oculus runtime than when using the OpenXr through SteamVR. Also the Oculus gave me somewhat crispier/clearer picture. Will test your method later today.

Agree, it works fine. It does require a powerfull Gpu as any streaming/standalone solution though.
Also worth mentioning is the active cooling which is very nice.

[St4rgun]

As others wrote it's obvious that MT's performance graph is incorrectly states "CPU bound" in VR when in fact there's a GPU bound situation. This was misleading me also, but as I reduced my settings with the G2 back to 100% and capped the frames to 45 with OpenXR toolkit the current MT OB produces smooth visuals in SP for me (OK, there're some occassional hiccups as well, but not much).

On the other hand I really miss the super crisp visuals and extended hotspot which I was able to get with 300% OpenXR and 60% FSR.

This raises the question: @BIGNEWYis there any possibility that DLSS implementation could arrive in the near future? Because that would massively help in VR. I know that the devs are extremely busy with squashing MT bugs, but DLSS seems kinda important...

I am having good luck with restricting DCS to physical cores only (all even numbered cores except zero). I have also set CPU priority always to high for DCS, Virtual Desktop and Steam. Probalance and high performance modes on. I have an AMD Ryzen 7 5700x, 8 physical cores. Strange thing though, running OpenVR benchmark I get 14% CPU usage but running DCS it goes to 34%. Still lots of headroom. But I have frequent crashes of DCS or Virtual Desktop even starting non MT from the VD streamer/ Oculus runtime. I am trying the registry change in a few minutes. Hopefully that will work.

Thanks. I'll give the even numbered cores a shot.

I have tried the same, and for me disabling SMT in either Project Lasso or BIOS made no difference

I only have 16 total cores so I don't have to disable SMT but I just tried two other things mentioned in this thread and they worked, I just played through a demanding mission 4 times with only one lockup. It happened when I double tapped the Pico passthrough to see where my drink was, LOL. All credit to the two people who posted these. 1. I shut of the audio streaming in VD and used separate headphones for audio from the PC. 2. I changed the registry entry to None, now MT starts in Oculus runtime if started from the VD tray icon, bin_MT. I'm now getting smooth 35-45 FPS. No problems even when I dropped a pair of CBU-97s. VD reprojection is turned off, it causes too much ghosting for me. Finally I can play until the next update when we will have to figure out work arounds for the new "improvements". All in all though, I think ED is moving in the right direction and have high hopes for the Vulkan engine. Although I wish they would check out the Unreal 4 engine, Assetto Corsa runs great in VR even loaded down with Reshade and Pure weather and its as old as DCS.

[schurem]

Disabling my SMT helped a bunch in stopping the stop-go nature of terrain when viewed at 9 or 3 o clock.

[Beirut]

I had a little 18MB DCS download on Steam yesterday. Any idea what that was?

[Minhal]

So what do you guys think will be under the tree today? Big drop or "only" bugfixes?
