WipeUout

The idea is good but the breath is too wide for three reasons. First, as stated above by @speed-of-heat, there are numerous mission type, scenario, terrain, airframe, etc. Second is the hardware variety and possible combinations, which is almost infinite. Thirdly, personal taste and tolerance toward details, image quality, refresh rate, etc. That is not to say it would not be possible but you would probably need a multi-dimensional matrix to cover all aspects and possibilities. I think that we have already a good set of guide for several type of HMD and VR support software. But I'm with you, the VR world need simplification and standardization, it is a mess.

Agree, same workload for both HMD. 90 FPS is achievable with the 8kX but you have to compromise on MSAA which is for me not a big problem with the resolution. Agree about the 60hz also but not everyone can sim at that refresh rate, I personaly can but not for prolong hours. The 60hz is also not available to all models of 8KX, only the first version has it. I also expect the crystal to perform better given the dynamic foveated rendering. My only worry is the trade off of FOV for clarity, is it going to be acceptable? I find that large FOV is such a critical feature to immersion. We'll see.

In my opinion, you will be disappointed with the clarity of the Pimax 5k+ compared to the G2. You will also find that the screen door effect is too much in the 5k+. If you want to switch to a Pimax HMD coming from a G2, then don't go lower than a 8k+ or even better, an 8kX if you have the horsepower to drive it. After all, the 5k+ is 2018 tech.

Ok, a little more explanation: Say your HMD is set at 90hz, this means that in order to have a smooth video, you need your system to pump more than 90 frames per seconds. If your system can't keep up and your FPS drops below 90, then you get stutters. MR or reprojection or smart smoothing, whatever it is called by your HMD maker, will insert frames to ensure the FPS never droppes below 90 using different techniques to predict how the next frame should look like if dropped because to system can't keep up. If you are a time traveler and have a 7090, then you absolutely don't need MR anyway.

It is the Pimax version of reprojection. It will kick in only if your FPS drops below your HMD's refresh rate.

Mee too.

hope you have a smooth setup! Good luck and let us know how it goes.

Sorry to hear that, I did have an issue with my 8k+ cable but it was quickly diagnosed and replaced by Pimax. My experience with them so far is very good but we all have different experience. Not sure about the Aero support. I am also keeping my 5kX for trade-in value when the 12k will be available, if ever. If you have some patience left, I will point you to this thread and you might find a solution and better performance, at least for DCS:

Here are my actual settings below. I am having the best experience so far with the 8kX, very clear and smooth visuals for the vast majority of scenarios. First the Pimax settings and then the DCS Setings. As you can notice, I use 90hz which is the maximum refresh rate on my 8kX (older model). The 75 or 60 hz is usable but a bit flickery in menus. Using 75 or 60 hz allows higher settings though if you can sim at that rate. At 90hz, you should be able to maintain at GPU frametime bellow 11ms most of the time with those setting but need at least a 4080. The CPU is no longer a limiting factor with Multi-threading(MT). For DCS settings, it is up to your personal taste but running the 8kX at native resolution, I find that MSAA is not required as the best cure for aliassing is higher resolution. If I run the HMD at 60hz, then I have the horspower to use MSAA but the quality gain is not that much. MSAA has a very high cost in terms of GPU frametime. On average, I increase my GPU frametime by 2.7ms which is huge and would force me to use re-projection and this is a no-go for me. Native resolution without reprojection is the objective! You may notice also that my gamma setting is pretty low and this is to reduce haze. It is a good and efficient way but you have to crank up your backlit and brightness to compensate. As for windows stuff, I have HAGS on with not issues and leave nvidia driver 3d setting pretty much at default except power management set to max performance. For other software such as Pimax client, PimaxXR and OXRTK versions, see my previous post. Running these exact versions is the key to have a smooth DCS MT experience. Some additional info about OXRTK: I do not overide the resolution but use Fix Foveated Rendering (FFR) at performance setting and CAS at 100%. Note that the pimax client FFR does not work with DCS-MT and OpenXR. We all have different hardware setup and this is why it is so challenging to find that sweet spot but hope this can help.

Coming from the Defense industry, NDAs are used to protect IP right and limit disclosure of company information to third parties. It is not to prevent people to do evaluation of a product. That is not to say that there can't be some bug disclosure restriction agreement made but it would not be called an NDA. Youtuber need vues and subcriptions to make money and it is entirely possible that some could be greedy and agree to omit some stuff in order to get first look privileges. When the Crystal comes in our community's simmers hand, then we will have a better picture of how good it is. For now, I based my assessment on pure specs and personnal experience with Pimax, I think the Crystal will be very good in DCS.

Wow, 8KX is absolute joy for me! And with your rig, you should be able to run it at native resolution! Talk to me dude.

I saw that in early reviews and in particular with 30 series GPUs, but seems to be resolve with the first production units. At least from youtuber MRTV it is not an issue as he tried both 30 and 40 series GPUs with positive results.

Looking at some recent reviews, I pull the trigger on a pre-order. Seems that with MSFS it is very good and even performing well with a 3080! From a spec perspective, this HMD as a similar pixel count as my 8KX but more compact, thus resulting in a much clearer image. My 4080 gives me the opportunity to run my 8KX at native resolution and even at 90hz. The resolution is so good that I don't even need MSAA, I think the Crystal will be even better with a PPD of 35. I will lose some FOV but I am already running my 8KX at normal FOV which is around 150 degrees horizontal, not a big loss as I wear glasses anyway. I also expect dynamic foveated rendering will help improve performance over fixed foveated. Can't wait to get the crystal!!

Mmm, not sure I understand this either now. Playing DCS on multiplayer or single player can be a basis for comparison but the best way to compare your setup with other is to use a track file to standardize as much as possible the testing environment. When using a track file, it does not matter where you are physically and everyone in the community can try it.

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.
