I’ve had no improvement with this patch. Which is a disappointment as I was hoping to see a slight improvement in VR when I heard about the optimisation on VRAM. 
I didn’t give any feedback at first because I wanted to fully try and tweak everything my end to make sure I wasn’t jumping the gun. I have no doubts that the team have put huge effort into this patch with lots of added features and I accept that all systems are different and some people have seen an improvement, it’s just not worked any better for me.

Yes, the same for me. I thought that VRAM optimization would positively affect performance, in fact Bignewy announced this as a radical improvement for VR (or so I understood it)... but no, in my case it has not been like that either.

Essentially, I must maintain the same low settings for two or three updates. I can maintain 45-80 FPS on land and at a very low altitude but I suffer constant stuttering, FPS drops, etc. with textures at medium. 

I would like for an explanation to be provided to the community regarding the nature of this VRAM optimization and the reason why DCS still utilizes the full 10GB of VRAM on my card without any noticeable improvement. Additionally, I have observed multiple videos from users that display the VRAM usage before and after the update, which appears to be unchanged. 

Concur with these reports - no improvement for me.  It's no worse to be fair, but certainly no better.  Still some stutters, still CPU bound, and still struggling with any unit-heavy campaign missions.

New Kola textures look great though.

If you have QV enabled in the new Pimax Play you have to disable the OpenXR Toolkit. They are not compatible.

You may try reinstalling Quad Views 1.1.3 and see if that works. I have it installed and despite the DCS warning it works perfectly.

Did this already. It was running flawless with just Pimax Play and it's native QV application. I am not using QV 1.1.3 the QV companion, PimaxXR or OXRTK!

Just one day later it did not work anymore.

Figured it must have been a Win 11 23H2 update. I deleted the Pimax folder in user/appdata/local and the metashaders2 folder in DCS saved games and it was running again!

Prior to the recent DCS patch I had updated Pimax Play to the latest edition and was pleased with the performance and image quality. However, following the DCS update there was a noticeable reduction in FPS especially at low level and a reduction in image quality. Switching between F1 and F10 caused a low of FPS. 

Not that I have in depth knowledge of computers I have been working away trying to recover to a point pre DCS update. I found uninstalling Pimax Play, QVFR, QVC, Pimax XR and OPENXRTK using the usual Windows method, followed up by manually checking the program files for any folders related to these programs and removing them. I then checked %AppData% folders Local, Local Now and Roaming and removing any folders linked to these programs. Following a PC restart I then reinstalled the latest Pimax Play, ticked the boxes in the DCS VR tab to include QV & ET. The net result is I have regained much of the FPS lost with a mostly steady 72 FPS. While the FPS  can reduce to 50+ over busy areas at low altitude and some minor stuttering can happen, I do feel  happier than just after the patch was installed. To reiterate I am only using Pimax Play and DCS now (Discord and SimHaptic also). 
This approach has helped me a non-expert and I offer it as an example which may help others if you are still struggling pending any update from ED.

What I have noticed since earlier this year which coincided with a massive fps drop when using the F10 map view, is random drops by around 15fps while running a flight. Alt tabbing then tabbing back into the sim and sometimes Alt and enter will make the FPS jump back to 45. 
I also completely avoid the F10 map view now because it’s such a pain to get the FPS back once I do it. I would really appreciate a work around of this problem as I know it never used to happen. 
I haven’t tried the Syria Sinai and South Atlantic maps as I have them on another install on another drive and haven’t updated that yet. So maybe I will see an advantage on those maps.

Just adding my similar experience.  Persian Gulf map (multiplayer) Quest 2,  Nice smooth 50 fps until going to the F10 map, upon returning to the cockpit, stuttery 24 fps or less.  In the past I could sometimes go BACK to the F10 map, do an Alt Tab til frames came back, then go back to the cockpit for a resumption of smooth play. Now that generally leads to additional frame rate loss and usually DCS crash.  Seems LESS pronounced in Single Player, but still seems present.

VR user (g2) and I can see no NVRAM benefit too, with 3080Ti I still have to use medium textures for heavy/new modules (ch47, ah64, etc.). OpenXR toolkit provides very useful statistics in CPU/GPU/NVRAM usage and you can see NVRAM 100%+ causes shuttering.

The F10 issue seemingly is affecting more people now.

Was the performance improvement mistakenly not deployed?

many people saw improvement, if you did not please post your dcs log and dxdiag in the performance section of the forum we can look for clues.

I'm one of those that saw huge improvement, even on Heatblur's Cold War server. It actually feels like a whole new game simulator for me.

I'm running a 5800X3D and a 4090, but I was having enough performance issues prior to this patch that I had to turn down some of my settings. Now I'm back to where I was previously, with even better performance.

We will continue to tweak and look for performance improvements. We are currently testing some more internally that hopefully we can share in the next update.

Yep, I think this last patch showed me you're all on the right track.

I'm looking forward to more improvements.

Eh?  In what way?

I'm reinstalling.  I don't think the first rebuild worked.  Nope.  Same results.  Does anyone else see what the F16 flight path marker does with full rudder deflection?  Or how it behaves doing a full roll?  I turned off the HUD symbology, and the flight model feels good, more like the F4 now.  The flight path marker needs some work.

I took the TF-51D out river racing, and I thought i was going to stall the turn when, whoops, I'm upside down.  Roll level and carry on.

Sadly for me, the performance are even worst now on my system in VR (5800X3D, 64GB RAM and 4080 super, Reverb G2, SSD nvme) with the last update.
I hope ED will keep working on performance improvement for the next patch.

That’s interesting, would you mind sharing some of your settings? In DCS as well as Steam VR. Also do you use stand alone DCS or Steam DCS? Also do you use/find motion Vector works for you with the Reverb? 

Best regards.

fpsVR tells me this build is more CPU hungry than before.  Performance looks smooth and consistent to me.  The future is multithreading.

I'm not a VR user, and my computer is very old. I did the reduced texture mod, somewhat improved it. Then I chose a scientific approach, and started with low settings, and pretty much all the way up, even with the ultra shadow mod. Only thing I didn't change was the prereload radius, and it's set at 100. I'm happy and everything loads faster.

Yes, I am facing the same issue. DCS takes almost 12GB VRAM and the range of the FPS change is huge around 30 to 80, especially applied the hotfix.  

I found out my issue.

My DCS is running from Steam, and Steam provides two versions:  1. Steam DCS edition, and 2. Preview MT version.  The "Steam DCS edition" one is very buggy and lagging, especially FPS (not playable).  The "Preview MT version" is the good one and very stable.

Just share it with the Steam users.

EDIT: I have done lots of home works and lots player helps and "Play DCS World Steam Edition" works for me.  My  summary can be found in the following post:

I'm always hitting Preview TM. But I've had serous preformance drop after the patch. A good 10+fps less.

Sure

It’s hard to know what makes a difference sometimes. There are so many variables with all the settings to the game and PC, combined with the effects of mods, it’s hard to know what’s relevant. Personally, I’m always trying new things people recommend for increasing performance.

With that in mind, here is my setup in it’s current state:

5800X3D / 4090 (undervolted) / 64GB RAM / Reverb G2

Standalone DCS with a fresh install just before the patch

The recommended settings in this video:

No mods, not even the OpenXR Toolkit or Quadviews.

Here are screenshots of my current settings. Let me know if I missed anything and I'll edit this post:

So, my question is :

after the latest update, do we still need to click on the bin  file  sent to the desktop or the original old one is already activating multithreating ?

This is what opens with the .exe in the bin folder. It looks like multithread just like they said

Thanks for taking the time to share this. Your PC is similar spec to mine but your graphics card is stronger. Can you maintain a solid 45fps with these settings and how does your antialiasing look on your external views? 
 

I’ve always found MSAA really taxing on my setup with the G2 and I actually find MFAA looks better for me personally. 
 

Also do you not experience any of the random drops in frame time that some have been experiencing and have to alt tab or alt enter to re-establish your frame times? 

thanks
