WipeUout

My favorite map is NTTR because I can crank up settings compared to other maps, except when flying over Las Vegas of course. I can maintain my GPU FT bellow 12ms easily with a native resolution (4k per eye) on my Pimax 8kX. CPU FT is not an issue anymore with MT. Do you have track file to share for comparison?

VR not a core DCS feature anymore and it's an off topic subject? Mistake or is there a message here? Dear Ed, put a little more tought on this please

Activating RBAR will have different outcome depending on the game. It may not in all cases improve FPS but it can reduce stutters or improve stability. The easy way to see if the feature is active or not is to use nvidia profile inspector. Select the game profile and scroll down to section 5. There is a small gear icon beside each selectable features. If it is gray, it is not activated and you can toggle it. If it is blue, then it is activated but not necessarily supported by the game. If the icon is green, then the feature is active and supported by the specific game. For DCS, the feature is still not supported unfortunately.

Glad it worked mate, happy flying!

Tried the mod with my 8kX at native 4k resolution using the "spotting-test2.miz" file. Without the mod I can spot the 32nm plane. With the mod I can't spot further than the 8nm plane.

@minimi66, If you have the time and patience, backup settings, then erase everything and re-install windows from scratch using FR33TY's methodology: I did it and was very happy with the improved performance and stability. Either windows 10 or 11...

I had a 6900xt for over a year and was happy with its performance despite AMD's low priority for VR. And then I switcehd back to nvidia and it was a big difference both in visual quality and VR performance. I did consider waiting for the 7000 series and I am glad I did not. Although they cost way too much, Nvidia cards are simply better for VR.

ST version does not show the issue, hence this is a DCS bug. ...and it has been reported:

This is very HMD dependant, what is yours? My Pimax 8kX is at native (100%) 4k per eye, so everything at 100% or 1.

Same issue here with 8kX. Strange light reflection in the left eye only. This is a bug and since it is also present in an HP G2, it is related either to OXRTK or DCS, I would rule out PimaxXR and Pitool/Pimax client.

Update!! Wow, MP is now working very well with latest OB 2.8.4. here is my recipe: OXRTK 1.3.1 PimaxXR 0.3.4 Nvidia 531.61 Pimax Client 1.10 I am not seeing the same performance as before when it was wobbling like crazy in the menus but very close within 0.2 to 0.3 ms for GPU frametime. Pimax client 1.10 is a must as with Pitool 1.0.1.284 the instabilities were still showing. Even the 2 second repetitive micro-stutter is gone in MP! Thanks ED and @mbucchia!!! I still have to try a few things such as compare Fixed Foveated between OXRTK and Pimax to see which is more efficient. Will get back with more update. UPDATE: Pimax FFR (still) does not work with OXR, on the other hand OXRTK FFR works well with 1.2ms drop in frametime, in my test track on performance preset.

Presently, it seems that results vary a lot depending on hardware. With a Pimax, OXR + MT is really bad in term of stability and quality of visuals compared to SVR. I get my best results with OVR + ST version, the image is clear, crisp and stable over time. I will admit the performance wise, OXR is a bit better, until it starts wobbling. Nevertheless the image is not as nice and clear. We are still in the early stage but as of now, I prefer OVR which seems much more mature and stable. Will OXR reach this? It take resources...

Well OXR is pretty good performance wise but very unstable with a Pimax, I have to turn on OXRTK turbo mode and limit FPS at my refresh rate to get rid of wobbles and stutters and still very unstable. OpenVR is working well but only in ST, MT is good but not possible to use Reshade with it. We are at the early stages of MT implementation... Looking forward to get DLSS implemented, I think this will come before Vulkan.

Yup. With the last iteration I was seeing no more that 0.5ms of frame time improvement and that was with 2.7.18.

What do you want to use it for? VR Shader no longer provide added performance and for the other stuff such as haze reduction, there are alternatives as indicated above.

I think it is still not implemented in DCS. If you enable it, the little gear next to the feature in nvidia inspector remains blue. If a feature is enable, the gear should turn green.

With the settings you mention probably yes, I can with my 4080. But the real beauty with the 8kX is running at native resolution which gives a very detailed view and minimize shimmering to a tolerable level without resorting to MSAA. Of course the view is even better with MSAA, almost perfect. I keep my refresh rate at 60hz to avoid any upscaling and can even afford MSAA 2x without problem on busy multiplayer missions with plenty of headroom. The 8kX at native resolution is really shinning.

Reshade is not compatible with the OpenXR runtime. Reshade will not work with MT using SteamVR runtime either. Only possibility to make it work is ST with SteamVR runtime.

Yup, MT working in SteamVR but can't use re-shaders. Performance wise, it is similar OpenXR CPU frametime.

I disagree, Pimax is not a plug and play but no worse than G2 and the extra WMR layer and miriad of possible settings. Speaking from experience. The state of things in VR is that there is no standard, every manufacturer have their own approach and it takes time and effort to optimize any HMD nowaday. There is also the PC in the equation, which have endless combination of hardware and requires tweeking and testing to get the best VR results possible. If it is a bigger sweet spot you want, then Pimax has that. Unfotunately, it might be difficult to get one, except the refurbished units on pimax.com. Cost is also something to consider because Pimax cost significantly more than a G2 considering you need a lighthouse and maybe controlers.

Reshade substitutes a DLL (dxgi.dll) in the DCS\bin folder and adds a "Reshade" folder with some other files and folders inside. It will only work with the ST version, not the MT even if you copy the files in the DCS\bin-mt folder. For now.

The only Reshade mod working with DCS that I found is ''VRToolkit Reshade'' (https://github.com/retroluxfilm/reshade-vrtoolkit) and it only works in SteamVR. Seems that OpenXR is not playing well with any post-processing mods, might be because it does its own post-processing and uses the same DLL. In any case, DCS-MT with Pimax and OXRTK/PimaxXR is not working very well and very unstable. I use DCS-ST with SteamVR with Pitool's Foveated Rendering (now working) along with VRToolkit Reshade, it is very stable and offer very good performance.

You are right, this is another solution. But there are also issues with SteamVR. Very glad you ask that question because it is not a bad option now! First, when using the MT version, the Pitool Fixed Foveated Rendering (FFR) does not work. FFR is a powerful feature that can improve performance significantly without sacrificing too much quality. With the wide FOV of the Pimax HMD, it is the ideal HMD to use with this feature. Unfortunately I tried many times, including today, and it will not work with SteamVR. On the other hand, it does work with the ST version which is new and welcomed as it lower GPU frametime considerably. From my testing, I have found a 1.0ms reduction in GPU frametime. This is using the balanced setting. This feature in Pitool is as good as the one found in OXRTK giving very similar results in improved performance. Second problem is the loss of sharpening with MT. The CAS sharpening option in OXRTK was very useful as the default VR view in DCS is very blurry. There are no sharpening options in SteamVR unfortunately but some mods can help. I tried many re-shaders and none seems to work with MT. On the positive side, I found that VRToolkit Reshade works perfectly with the ST version. This is also very welcomed. You just have to find the sweet spot as too much sharpening can make the FFR circles visible. In all, the ST version using SteamVR is pretty good and on par with using ST with PimaxXR/OXRTK as far as performance. I also noticed that SteamVR seems more stable with less random stutters. I still need to do more testing but so far so good, this is what I will be using going forward until MT is fixed.

Do you have his contact info?

I run my Pimax 8kX at 60hz in order to get native resolution, 90hz is not achievable without scarifying image quality too much (for me). My 4080 is pretty good and the i9-13900KF is smoking fast but we are not there yet and I doubt very much I could drive my 8kX at 90hz even with a 4090 at the same level of details going multiplayer in Syria. MT is not the determining factor for me, my CPU is pretty powerful. But if you play dynamic campaign like DCS-Liberation or fly on enigma server, then MT is making a difference.
