Not only that but I believe the Vive Focus Vision will work with Mbbuchia's QuadViews in Fixed Foveated rendering mode. (If you are unfamiliar, basically a method for blurring the outer periphery where you are not looking to regain FPS.)

Welcome. Just read the reviews Qcumber, you will see many issues with Pimax. Also, I notice your 4070 card, ... easier to push the QP. You're just going to get an all-around better experience.

My experience completely aligns with av8orDave. Theoretically on paper, the Crystal Light should be the HP Reverb G2 2.0. Everything seems great, .... on paper. In real-life, there are too many build issues, software snafus, and problems with Pimax support to recommend the Crystal Light. In the back of my mind there is a counter, .... call it, the, .... How many times does X headset f%^@ up in one month reliability counter. The Crystal Light ticks pretty high, ... the QP does not. Because the hand tracking has become so good with the Quest Pro (no need for devices like PointControl), and I can reach a stable 72 Hz with pretty much any aircraft with all DCS settings maxed out, it has become my go-to high-end sweetspot. The QP does not deliver the pixel density of the Varjo Aero but its usability is higher. You get 95 to 97% of the Aero with a less time consuming experience.

I set the Pixel Density from within DCS up to 1.7, ... so 3060 x 3264. (On the desktop, from Meta's Link software, I left my slider at 1.0) (I also tried the obverse, setting the Link slider to 1.5 and then adding on a bit from Pixel Density from within DCS. The results were analogous.) I can run the Quest Pro at 72 or 80 Hz with everything in DCS maxed. I am just a tiny bit short of being able to run everything at 90 Hz. No, ... I didn't try every map or every plane. 90% of my testing has been with the Hornet on the Syria, Dubai, or Marianas maps. (A common mistake I see here at the forums is believing that the next flagship graphics card will allow someone to run X headset with everything in DCS maxed at 90 Hz. If you have the 4090 and were hoping that the 5090 would finally allow enough headroom to run the Somnium, Crystal, or Aero at 90 Hz with all DCS settings maxed, ... you are going to be badly disappointed. Unless, DCS implements DLSS 4 (a' la Cyberpunk 2077), you will not be able to run the Somnium, Aero, or Crystal at native or higher resolution with everything in DCS on highest/ultra settings at 90 Hz. It just does not have the ceiling for it.) If you own a 4090, the 5090 provides very little extra headroom. As one of the other members noted, ... if you have been waiting four years to upgrade your 3060 and finally have $2500 (well, ... with the possible tariff situation unstable, ... say, ... $2800 (wait, .... weren't prices supposed to begin dropping? ... every price I see continues to climb)) laying around, and your town happens to be close to a nuclear power plant, ... have at it.

Guys, I teach full time at uni, have a family, and a child. I was fortunate to even get a weekend to myself where my wife and son went off for his fencing regional. I will be lucky to get another weekend like the past during this semester. If the information I listed in the first post of this thread is helpful, ... great. If it is not, ... or you distrust it, ... I suggest either waiting till more DCS VR users acquire 5090s or purchasing one for yourself. You will confirm what I have found.

You're under no obligation to believe in a free online forum. Test yourself. (You will find the same stats I found) What I can say is that I got the G2, Quest 3, Quest Pro (and ole' Valve Index) working right off the bat. The Aero took a great deal of cussing and six hours of fiddling with to get it working with the 5090. (Please remember for theses tests that I used an ASUS TUF 5090 and not the far more common Nvidia reference card.) The Crystal worked fine for me on Sunday although very oddly I had to connect it to the middle Displayport (of the three - on the back end of the ASUS TUF card) Any other connecter, and I had a dead screen. On Monday, sadly, (and perhaps like you), ... I am back to a black screen. ... Zip. ... Normally, at this stage, I would spend whatever time was needed to get it working but after long experience with Pimax, their software, their "support" team, ... this is one problem I will not be coming back to. (To be fair, out of all the headsets we have here, it was the Crystal I most expected not to work. It is extremely temperamental to say the least. Now that it is not working again, .... not my concern. I ran out of goats last week and have no plans to secure more to sacrifice at the local Temple of Apollo to get the f$%#er working again.)

Dragon, when it comes to DCS finally incorporating Vulkan, a particular image from the movie, Sex Drive comes to mind:

Vulkan has less chance of becoming a reality than men landing on Mars by 2035 or Duke Nukem returning for his third major sequel in 2041. It is a mirage. People have been mentioning that $%#! since I (believe) at least 2017.

@Dragon - DCS has never been coded to take advantage of Nvidia's SLI technology. @Hippo - Fixed the percentiles to be readable. (Thanks, ... I like guys who notice the fine details.)

Without framegen. Take a look back at the the reviews released right around the time the RTX 4090 launched (places like Tom's Hardware, AnandTech, Tweaktown, Guru3D, etc ...) where they would show averages across 20 or more major titles at different resolutions. In 4k, RTX 4090 was beating the 3090 Ti by roughly 50 to 70% iirc. Occasionally, the 4090 would pull a low score where it only beat the 3090 Ti by 35% or so, ... but in another title, it would double the frame rates. Long story short, ... the 4090 was a "good" release. In comparison, so far, the 5090 is turning out to be (at least from the perspective of a DCS VR user) a "poor" release.

Perhaps I got lucky? My Crystal has been, ... shall we say, ... temperamental, ... to say the least. On Sunday, she was not. (Thank you Zeus and Athena, ... ohh, ... and Sotha Sil.) I usually sacrifice a small goat before I fire up my Crystal, ... no goat needed this time, ..... YAY! (I will say for all the math, physics, and engineering nerds out there like myself who will get this joke, ... I am endowed with an anti-Pauli field. After many years of experience, ... things in a lab that rarely work, ... often work for me. The opposite of the well-noted Wolfgang Pauli (my 2nd favorite physicist) effect.)

Like you, I was hoping for at least a 30% improvement, .... especially for $2500. (Actually, for $2500, I was expecting a real-world, fully nude, 32-22-32, 5'8", 114 lb, cheerful, no-STD, attractive faced, intelligent, female to ring my doorbell and help "install" the card along with other "services." I managed to get through to Jensen, ... and he informed me that due to heavy demand, ... she is coming, ... but on Thursday, .... (m$%##^$#@$@!). .... I mean the nerve of these guys to pull a stunt like that. Three dreaded days of waiting, ... . Future 5080 buyers take note, ... you only get the bobblehead doll of her, ... not the "services" package.) Joking aside, I had the same hopes. Sadly, that is not the results I measured. That said, the 5090 will pick up real benefits if like Cyberpunk 2077, DCS adds DLSS4 support down the road.

Yes, Hippo, you are right. The 4090 often beat the 3090 Ti by 70%. (In this same manner, the 5090 is beating the 4090 by about 21% (averaged).) To my mind, I am always used to setting the previous flagship card (in this case, the 3090 Ti) to 100%, and measuring from there. But yes, you are exactly (mathematically) correct. Let me fix that in a few hours at lunch.

Thanks Phantom! Also guys, ... don't read too much into anything other than the results I measured. If you have a 3080 card and it is not doing it for you or you always hated not being able to max out X or Y headset, ... and you now have $2400, .... then great, .... get a 5090! My only point is that if you already have a 4090, .... mehh, ... not much of an upgrade. I think many were hoping that the 5090 would be this monster, ... just like the 4090 was. A card that would outperform the 4090 by 50% or more. Sadly, Nvidia's cycle continues on ....

But why Evil? Wouldn't it be better to be known as GoodBert?

As many have observed, it seems that it is every 2nd generation of Nvidia cards that gets it "right." 1080 ti, ... meh, .... 2080 ti, ... right. 3090 ti, ... meh, .... 4090, ... right. Following in that pattern, .... 5090, .... pass. And you are perfectly correct Phantom, .... I often joke but using sarcasm. Sarcasm is a much misunderstood thing in the Marvel movie and literal era of the present United States. That is why my passage through any forum has a measured half-life

I post across several forums and you can always find the real me by my signature; A wonderful method for appreciating the beauty of the Multiverse is to learn the language in which it was written, .... mathematics. And that is the truth. Want to understand our reality at its deepest levels, ... look first to particles, ... then picture fields (quantum fields), .... then Information Theory renormalizations of quantum fields (and/or equivalently, ... stress-energy tensors from GR), ... then past ennui (along with strings and branes), ... and finally, ... as T.S.

You are speaking of using VR headsets priced in the thousands and then combining it with a card priced at roughly $2400 or more. Congratulations, ... you are either a surgeon, another speciality of medicine practitioner, a dentist, a pro athlete, or a highly paid lawyer, or a trust fund baby. You Sir have succeeded! .... Congrats (Clarification note - When the 4090 was released, it was outperforming the 3090 Ti by roughly 70% across many titles. It was apparent early on that the RTX 4090 was going to deliver the "goods." In some titles it doubled the frame rates offered by the 3090 Ti, ... in others, it beat the 3090 Ti by only 45%. It was a true jump up. The 5090 is the complete opposite. For the massive electricity bill it will take to run it, it is worse than the 4090.) Coming back down to reality, ..... your situation specifically EvilBert, ... even for VR users, ... is less than one in 10,000. You can take a look at the Steam VR headset usage for December, 2024 here: As you can see, the Xtal is not even listed. (Please note as well that only about 2.3% to 3% of U.S. based Steam users are even reporting a VR headset. An Xtal owner is like finding a 3 carat diamond in a coal field.) My only request, ... when you drive by in your Bugatti with your Xtal sitting nicely on the passenger seat, .... could you throw a Benjamin or two out the window? Oh, ... and why EvilBert? ... Why not Good Bert? .... The world is filled with bad people and far too few Nelson Mandelas and Jonas Salks.

Been fooling around with the ASUS TUF 5090 card in our labs and on average, it only beats the 4090 by 21% across most major titles. (And I don't mean the hand-picked titles that Nvidia showed at their reveal presentation.) As many of you know, this card requires up to 600 watts of power (the 4090 requires up to 450) and if you are overclocking everything else, you safely need a 1200 watt PSU. It requires a 33% increase in power over the RTX 4090 to provide a 21% improvement at the screen, ... which is pure s$%! for a flagship card. And that does not even take into account the very large price bump. (The ASUS TUF we were able to secure was almost $2500 US dollars compared to the $1780 ASUS TUF RTX 4090 we procured back in Nov, 2022.) Specifically, for DCS while using the Reverb G2, the Quest Pro, the Quest 3, the Varjo Aero, the Pimax Crystal, and the Somnium VR Ultimate Edition: (the G2 and Q3 are using Mbbuchia's Fixed Foveated rendering mode, while the Pro, Aero, Crystal, and Ultimate are using Mbbuchia's true eye-tracked quad views) G2 - 11.3% increase over the RTX 4090 with Fixed Foveated Q3 - 14.8% increase over the RTX 4090 with Fixed Foveated Q Pro - 17.3% increase over the RTX 4090 with true Quad Views/eye tracking Aero - 14.4% increase over the RTX 4090 with true Quad Views/eye tracking Crystal - 11.8% increase over the RTX 4090 with true Quad Views/eye tracking Ultimate - 13.4% increase over the RTX 4090 with true Quad Views/eye tracking Forum member Flextremes below mentioned that the 5090 should respond well to the 4k+ pixel heavy demands of VR with the card really showing its muscle with the high-end headsets and resolutions (think Aero, Crystal, and Somnium). I expected the same but sadly, I have not found that to be true. Of course, DCS World is not a game which currently offers DLSS 4 which the 5090 is custom built to made to take advantage of. Still, imho, this is the worst generation of flagship cards in the last decade. Although we don't have one in our labs, it seems the 5080 will not beat the 4090 in anything. I do not recommend the RTX 5090 for DCS with VR. (Some will ask what settings I am using - In short, ... everything maxed to the hilt. Mbbuchia's Quad Views does not work well with Lens Effects or Bloom, so those are off. Except for that, I've got everything, ... shadows, water, terrain, clouds, etc ... maxed at high or ultra. I am using DLSS with AF 16X. I am able to fly with the Quest Pro at 72 fps. To get that or higher with the Aero, Crystal, or Somnium, I have to dial back some things if I run at those respective headset's native resolutions. The very, very best combination of detail and definition and color gamut is through the Somnium VR1 Ultimate but very, very, few are ever going to be able to shell out $4300 for a headset. A tiny, tiny, smidgen down from there for absolute best is the Aero. Overall though, ... and quite surprisingly given its low native resolution, ... the high-end sweetspot imo is the Quest Pro. By dialing up the resolution (through the desktop Link software) and using Quad Views, you get 95% of the eye candy of the Aero, Crystal, or Ultimate at a far cheaper price. Temperature wise, the 5090 tends to run about 4 deg C higher on average than the 4090. After a good hour of flying the Hornet in Syria or Dubai, I had GPU temps of 74 deg C and memory temps of 84 to 85 deg C (the RTX 4090 sitting in my second rig under my office desk averaged about 69.5 deg C on the GPU and about 77 deg C on the memory in the same situation with the room temperature set at 72 deg F). The actual work being done by the card (wattage is electrically speaking, work) averaged 570 watts over this one hour. From a noise perspective, the 5090 was the ASUS TUF card I used was almost identical to the ASUS 4090 TUF version. I have not overvolted the 5090 card yet, nor have I overclocked it.) (Edit - Had time to today to add the Aero and Crystal to the results)

Make sure you have the Meta Horizons app downloaded for your phone and that the "developer" option is enabled (by opening a developer account with Meta, .... absolutely ridiculous). Occasionally, ... and for no reason, ... the app decides to revert back to preset behavior. This happened to me once about two months back. Might be worth a shot. The crazy things about the Quest Pro is that there are not one, ... not two, ... but three places to adjust settings (the Meta Horizons app (phone), the Meta Link software (Windows desktop), and the headset itself (the cliffhouse with waterfalls in the distance)). All three have settings that have to be "on" to get eye tracking rolling.

I agree with you fully Mbucchia but if you discount the Meta stuff and the G2 is no longer a go with WMR being removed, that leaves either super-expensive Varjo or Pimax. Theoretically, if Pimax ever got all their issues sorted, they could, ... (key word here, ... "could") ... become the premier main-tier headset offerings but they have too many issues. That means that once the typical simmer walks the full circle, ... they (sadly) arrive back at the same place, .... Meta. (Trust me, I don't like Meta, their policies, or Zuckerberg)

13900k and 4090 here, OXRTK does nothing for me (MBucchia recommends not using it). Quad Views with my Quest Pro really does work well. Best situation I have ever had in VR for enemy plane spotting during ACM.

(Current or past owner of the Rift, 8K, Index, Rift S, G1, G2, Aero, Quest Pro, Crystal, Crystal Light, and Quest 3) Yes, you are right. The Quest 3 is the best at, .... it just works, ... (for most people under most situations with the least snafus), ... for the $500 and under price range. My Crystal and Crystal Light have been less than fully reliable (build issues, software issues, customer service issues, etc ...) On paper, the Crystal Light seems like it beats the Quest 3 for seated PCVR, ... but in real-life, ... no. You also don't need the $79 official Meta Quest Link data cable (you can use this). You can also buy upgraded face gaskets and head straps online for much cheaper than some of the prices being floated around for supposedly high-end models. If spotting is very important to you, you might look at the Quest Pro. When I received this headset, I was prepared to dislike it bc of the low resolution. The pancake lenses though + the QLED screens in conjunction with MBucchia's Quad Views software package allow me to dial my resolution very high at 72 or 90 Hz. (The Quest 3 can work with Quad Views, but only in Fixed Foveated mode while the Quest Pro has true eye tracking and can benefit even more.) It is not quite flatscreen OLED 4K clarity, ... but it is not far off. The Varjo Aero is extremely good and has the better pixel density but Quest Pro with much lower resolution surprisingly pulls about even (if you use Quad Views) due to its even better pancake lenses and QLEDs (versus the aspheric lenses and mini-LED screens of the Aero). You would not think it by the listed stats but in-sim, the Quest Pro is actually my preferred headset for spotting/dogfighting. The Quest Pro also has full eye and hand-tracking which means you don't need to use PointCtrl or any of the other finger pointing devices that some advertise in the VR forums. You also don't need external Lighthouse tracking stations (thank god!) and the headset is better balanced than the Quest 3. Finally, the included hand controllers are the first I have ever used that beat the Valve Knuckles (Quest Pro hand controllers are self tracking). You get a great deal and the Quest Pro currently goes for about $800 new or from ScumBay for $600 or less for used.

DCS loads slowly, poorly and sometimes, ... not at all. If I were wrong, why seven "reproachers," .... one should be enough.

@ SlipHavoc, Thamiel, cfrag, .... I hear Draconus is holding a DCS appreciation festival. Have you received your invites yet? Apparently, it's going to be quite the event.
