WipeUout

The Crystal has two tracking options, internal or lighthouse. Controllers are not required in DCS.

If you go fresh install, follow FR33THY's videos on youtube, very well optimized method for gamers:

Look here:

Did you check your DCS log to see what is happening before the crash to desktop?

Very puzzeling. I guess you already tried to plug your HMD in different display port connector on your GPU? Or tried the HMD on another computer? Or tired with an older GPU? I did have a similar problem with my 8k+ and the cable had to be replaced, but if you tried with two 8kX with same result, the problem has to be computer hardware or software related.

Send your video to Pimax support, you might have a cable problem.

Tracks made in VR must be replayed in VR, there are no way around. Else, re-do your track in 2D and it will be fine on replay (in 2D).

I believe that Valve index does not support OpenXR natively. Have you followed the instructions in the first two posts here:

If you are using Pimax Client 1.16, it might be the problem as 8kX owner are reporting issues. Try rolling back to 1.13.

What version of Pimax Client / PmaxXR / OXKTK are you using? I use Pimax client 1.14, PimaxXR 0.4.0 (Have not tried 0.4.2 yet), OXRTK 1.3.2. It is the most stable combination at 90hz. Also, if you use turbo mode in OXRTK, it may bring instability.

This is already reported and being investigated. Go to the VR bugs section to see progress:

Interesting question. I tested both DCS PD and OXRTK at the exact same super sampling value and they are both performing the same, PD=1.1 in DCS and 10% more resolution in x and y values in OXRTK with a result of average 9.14ms and 9.16ms respectively in GPU frametime in my test track. The only difference is the granularity that OXRTK offers. In DCS with the PD, you are limited to 10% increase in each axis as opposed to OXRTK where you can increase by one pixel at the time. Much more precise but also much more time consuming finding the sweet spot.

First thing is to manage your expectations. VR is giving up quality of visual to get a more immersive experience. You will be in the sim instead of looking at the sim but will lower quality visuals. Remember that. Get the most powerful GPU you can afford, this is critical and more important than getting the most powerful CPU. Playing DCS in MT (Multi-threading) does not require the top CPU. Your graphics card will be the bottleneck of your system in VR. You have a good VR Headset with good resolution but there are a lot of pixels to render and it take a lot of power to run and maintain high FPS. Compromise on RAM (32 vs 64), same for CPU and expensive overclocking mobos. Get a 4080 or 4090 if you can.

Working fine here. Have you try a slow repair? Sounds like you have corrupted install... do you use any F-14 mods? Sometime not disabling the mod before an update can cause this sort of issue.

One thing you may try is to assign priority interrupt for your graphic card. Run the attached file as administrator, locate your GPU in the list, click on the msi box to so it turns blue, click apply and re-boot your rig. After boot, run again and check that there is a dash next to the irq number to ensure msi is activated. In some cases this has improved micro-stuttering where there is competing priority between sub-system trying to get the CPU's attention. Msi Mode.exe

Your ideal VR solution will be personal and tailored to what you can afford. There is no standard here and if I can give you only one piece of advice : try it before if you can! As I wrote a few times before, the VR proposition is to sacrifice quality of visuals for immersion. In VR you are not looking at the simulation anymore, you are in the simulation. I will try to give you my take (very biased) on the features you mentioned in your title: Refresh rate: There are HMDs out there that have all kind of refresh rates up to 180hz with the pimax 5k super (possible but with lowest FOV setting only). Some people can sim at 60hz, most prefer to have 90hz which is the sweet spot I would ague. Having the ability to switch refresh rate is interesting to allow different settings depending on the map you use for example. With lower refresh rate you can have more details or resolution or tackle busy scenarios. A setting that is used in VR to cope with low FPS is re-projection. This is great to ensure a smooth video but at the expense of artefacts and ghosting, which is not tolerable for everyone. If you can try it before hand, it will be an important factor in your decision. FOV: Here the Pimax 8k and 5k offer the widest. For my personal taste, FOV is a critical element of the immersion experience. I've tried the Index, Oculus 2, Reverb G1 and G2 and Varjo and would never switch to anything on the market now for my 8kX. Nevertheless, a lower FOV will still give you a huge difference in immersion over 2D flying, and is also less demanding on your hardware. Tracking: There are basically two possibilities here, inside or outside tracking. In other words, tracking performed internally by the HMD or through external means such as the ''lighthouse''. The most accurate and stable tracking way is the outside but it cost more as you need extra hardware (1 or 2 lighthouses). that is not to say the inside tracking can't be good, there are HMD that are pretty good at this also. good luck!

Sounds like a pretty good fix, are you on steam or standalone? Can you expand about "just clearing the DCS game folder"? i.e. delete the folder directly or do uninstall through windows settings?

Absolute reverse experience. I have been steadily keeping track of performance since 2.7 and the sim has been getting better and better even though new stuff/features has been added. We did have a drop with shadows at one point but prerformance now is better. I would agree with most here as to your issue is not the sim but settings...

3D will look as good as 2D the day we have: -HMD that match or surpases the humain eye equivalent PPD which I read somewhere is around 60-70 PPD. -Hardware that can render the huge amount of pixels required to get 60-70 PPD at a decent level of details and FPS rate. Until then, 3D will always look less detailed than 2D. Nevertheless, the VR proposition today is to trade quality of visuals for a higher level immersion and much more realistic experience.

I considered going for it and even shelled the 30 bucks. I changed my mind and I will not get it. Based on the reviews out there, I think that the crystal is a transitional HMD and not offering enough from what I can do with my 8kX, the tradeoffs would simply be too much. I had a hard look at the quest pro also, it is a slick HMD which sports DFR and local diming also with a much more mature design. Going from the Quest Pro to Crystal will bring you basically more resolution, a tad more FOV but a the expense of performance, then you will have to scale down settings and quality to achieve a decent FPS rate. I don't think it is worth it. For me, I will wait and upgrade my GPU instead as I am still not exploiting the full potential of my 8kX with present hardware.

Sorry to hear that. Your experience, not mine. Only issue was with my 8k+ cable that was replace fairly quickly. the 8kx has been flawless but it sure needs a lot of tweeking and a beasty rig to get the best out of it.

I just can't believe he said it's a game

Yes, I agree. Barrel distortion correction can be very confusing and should not be the focus as it is not a variable in the user-controlled performance equation. Rendering resolution relative to the physical HMD resolution is the key element to understand and where the very bulk of the GPU's work is done.

Smart smoothing not the same as compulsive smoothing. Smart smoothing can only be enabled in Pimax client and does not work very well as transition between full and 1/2 FPS causes stutters. Did you try to enable a game specific profile and uncheck the smart smoothing box there?

My understanding is that it is not super-sampling but barrel distortion correction which is specific to each lenses and HMD combination. Super-sampling means rendering at a higher resolution and this is not the case with barrel distortion correction as the HMD stretches the image by using shaders, which is much less demanding from the GPU. My 8kX has a factor of 1.9 (190%) when I use the full 160 degree wide FOV. Good thing shaders do that job, else my FPS in VR would be less that 1/4 of what it is in 2D. As for the Pimax way to advertise resolution, not very honest indeed... nevertheless, I enjoy my 8kX, it is simply stunning to sim with this wide FOV. If PimaxXR reports that resolution, it could mean that you are Supersampling a lot your image. I doubt very much that the Crystal has a barrel distortion correction ratio of 21.99/8.3= 265%. You are overriding the resolution in your game/render quality setting in Pimax client, probably set to "maximum" or "customize" with a value higher than 1.
