“What’s the best VR HMD for me?”

More to the point:
“What’s the best VR HMD for Flight Simulation that’s available to me now?”

The first most important tidbit you need is to STOP trying to choose a VR HMD based on advertising and opinion around general gaming. Flight Simulation graphics engine requirements are vastly different than the VR games being presented generally in the Oculus Portal and on Steam. What’s seemingly crystal clear in a portal game is not representative of the clarity you won’t have in a flight simulator.

You should also know that I’ve tested each of the 5 devices (listed at the end of this article) in DCS Single Player and Multi-Player. The Comparative Chart on this site includes my tested experiences.

The primary focus of the VR4DCS Blog is VR For Study Level Simulation to include DCS, Prepar3D, X-Plane, and to some degree IL2. My thoughts and answers are geared to this genre and purpose.

If you’re looking for help on choosing the best VR HMD to primarily play games in the Oculus Portal, you’ve just answered your own question and you can stop here.

If you’re looking for the best experience in VR for a Study Level Simulation, the choices narrow and require a look into some of the technical specifications, as well as what matters most in these Sims.

I’m going to break this into a series of questions in 5 groupings where you can better examine the factors of your choices. Sometimes just putting these choices to ‘paper’ can help you narrow your selection and best align the factors that matter most you.


 

Marketing=Perspective and PPD=Clarity

For Simulation Pilots, that marketing perspective is not relevant to your needs of running a Flight Simulator. The marketing tag about how clear the Oculus Rift S is compared to the Rift CV-1 is focused on low-res portal games with low polygon counts. Compared to the view in the CV-1, yes, the Rift S is much clearer. But placed into the context of Flight Simulation with high polygon counts, fast action, and high-res shaders – The Rift S may not be the device to be pursuing for the deep simmer.

Pause here and check the PPD numbers on the Comparative Spec Chart. When compared to the best VR HMD’s for simulation sorted by PPD, the Rift S is quite a bit lower in clarity when used in Flight Simulation.

Some manufacturers market their devices in Total Horizontal Resolution of Both Eyes x Vertical Resolution. Not only does it confuse people, but it’s also just bad marketing. Sure, some use a single LCD panel across both eyes, some use two LCD’s screens one for each eye. What really matters is what you can see with one eye, no matter the technology. One eye always only sees the perspective for that side. Don’t be fooled. If the horizontal resolution seems very high, you may need to divide it to see the single eye resolution.

The specification chart on this site uses a single-eye view for comparison no matter how the manufacturer chooses to market the device.

The most recent offender was Vive regarding the Cosmos. Vive eventually had to produce a statement that said in essence, “Yes – we used the resolution of both eyes to get to 2880. It’s really 1440 per eye.”

The Reverb really is 2160×2160 in per-eye resolution. Look on the chart, that’s quite a difference, isn’t it?

Your friend who has a Rift S and plays mostly Portal Games but does not play DCS is going to be thrilled with his view. But it’s not even close to what you would get for clarity in the Index or especially the Reverb.


 

Question Sets for determining your needs and best fit.

The following should help you define what’s important to you in a VR HMD and help you to select the device specifications that best meet your criteria. Don’t worry, it may be your first VR HMD, but it won’t be your last. There is a good resale market for the devices, you can always choose another one.

Question 1: What are my needs?

Question 2: What devices are available to me?

Question 3: What are my expectations?

Question 4: How much does it cost?

Question 5: What about the specs for VR HMD’s matters most for Flight Simulation?



Question Set 1: What are my needs?
My Experience with VR is:
  • I’m brand new.
    • Consider that you have much to re-learn about tuning and graphics interaction, you may not want to step into the top end right away.
  • I have a CV-1 or a Vive or similar and I want more clarity and better performance in my Sim.
    • You have some experience and are now ready to tackle more rig tuning and technical setup to get every bit of clarity your simulator can provide.
What do I want in my Simulation Experience?
  • I want the best clarity to spot targets as far away as possible.
  • I want the widest field of view.

We want both of those specs of course…but right now you can’t get both.
You must go back and choose one… Hint: Choose clarity.

My expectation for using the VR HMD is:
  • I only Sim with DCS, P3D, X-Plane. Nothing else is played often enough to matter.
    • You should look more closely at the higher PPD devices for your VR experience, they’re capable of proving you the detail you may not even see on your flat screen.
  • Mostly Simulation but my household would like to play the portal games as well.
    • The highest PPD devices will run portal games very well but lack the refined consumer experience you may be looking for.
  • Mostly portal games but some Simulation.
    • Concentrate on the devices that come with a consumer portal for gaming, have fewer parts and tuning. You probably won’t miss the detail you aren’t getting with lower PPD devices.



Question Set 2: What devices are available to me?

Here you’ll have to do a little digging. Reviewing the major VR HMD’s on the market and the stores they are sold through that are available in your home country or area. If you don’t see it in your area, call the manufacturer and ask. Most reputable ones will let you know about when or if it will be available to you.

This can be tricky, as some are available at a later date (Reverb re-release in EU). Some may not be available at all (Odyssey+ in the EU if ever). Others are widely available as stock replenishment occurs (Realistically all VR HMD’s are widely available in the US; some just sell out quickly).

Make your list of “Available Now”, “Available Soon”, and “Never going to be available” VR HMD’s for your area from your research. This list will help you to stop spinning your wheels on an item that just isn’t going to be available to fill your needs.




Question Set 3: What are my expectations of this VR HMD?
Your VR Mindset Is:

1. This one I’ll have for a year or two.
2. I’ll upgrade every time the technology gets better.

If you’re primarily a Flight Simulation junkie, you’ll upgrade this as much as you upgrade the rest of your rig. Getting one or two years out of your initial VR HMD is quite a lot.

Every six months to one year the VR technology gets better in a big way. Expect if you want the latest and greatest, you’ll have a solid secondary market to sell into.

What it takes to set the VR HMD up for use:
  1. It better be out of the box ready.
  2. I can handle some light tech, willing to learn to make it work.
  3. Experimental, oh yes – I’m up for digging in.

If you are honest and rate yourself in the #1 category, stick with the consumer-grade portal VR HMD’s for a while. Then look to upgrade in about 6 months.

If you’re a #2 then you have quite a bit more choice and with some guidance can get into top-end clarity with just a bit of work.

If you’re a #3, currently the higher end requires some tuning and technical configuration to get running. If you’re into experimentation and figuring things out, the higher end of the VR HMD spectrum will be that much more fun for you.



Question Set 4: How much does it cost?
What are those true costs of getting into VR?

This is the same cycle you’ve lived for years pushing pixels on a flat-screen. You’ll need about 75%-150% more horsepower for VR than for entry-level simulation use. Keep in mind, individual component updates just move the bottleneck farther downstream. Upgrade your GPU card and you may not see a great difference if you don’t have a gaming-grade motherboard that can sustain the throughput.

We won’t cover all of that here, we’ll just stick to the main parts categories.
In making your own comparison table, take into account the following, decide if your current Rig is up to the task, and add some costs where you may need to upgrade.

Stay away from the “minimum” specifications for DCS or any VR HMD manufacturer statement.
Look for “Preferred or Optimal” – minimum isn’t where you want to be in DCS or study level simulation, ever.

Components of Price
  • VR Headset price
  • External Tracking Devices (If required)
  • VR Hand Controllers (if not included and required)
  • Extra Cables, Extension Cables, available power.
  • GPU powerful enough to drive your choice of VR HMD, with the correct video ports available.
  • CPU/Memory/Cooling/Motherboard combination capable of sustaining the processing needed for the number of pixels being driven.
  • USB 3.x available ports, power, throughput. Might be best to have a PCIE USB powered card.


Question Set 5: What about the specs for VR HMD’s matters most for Flight Simulation?
The Short Version
  • Physics vs Marketing. Math is Real – Marketing is Perspective.
  • $Billions spent on software pay off.
  • Pay attention to what matters for simulation, not the hype around portal gaming.
  • The good stuff and the new stuff costs more. (price is a spec)
“The best VR Headset on the market today is the one that makes you happy.”

Taking into account your answers from the previous 4 Sets of Questions, adding those to the physical capabilities of the available VR Headsets should yield an answer that makes you comfortable with your choice. You’re on your way to VR Nirvana.

Specs to care about:
  • Pixels/Resolution
    • This still matters. Period.
    • High-res on the Horizontal coupled with a much lower-res on the Vertical = less PPD and less clarity.
    • Forcing a better picture in a lower-res device means mushing pixels together.
      (It seems less jaggy but really your distance view just tanked)
    • Lots of pixels to push means lots of horsepower to get them going.
  • Sub Pixels
    • The device with a 3rd sub-pixel is overall clearer than one with 2, and means clearer text up close.
    • 3 sub-pixels makes a device seem clearer than a VR HMD with 2 sub-pixels that has a similar or slightly higher PPD number.
  • FOV
    • Large/Wide FOV with a low PPD will seem very grainy.
    • On average with a 114-degree FOV, you’ll see about 90-100 degrees.
      • Why? Because your eyes set back a bit from the screen.
    • Only the Pimax doesn’t seem like a Scuba Mask inside at 150 degrees FOV.
      • But the view is a lot less clear than a Reverb at 114 degrees FOV.
      • You lose that scuba perception quickly in any comfortable HMD.
  • PPD
    • PPD (Pixels Per Degree) is the measure of clarity for a simmer.
    • The higher the PPD the clearer the close-up view & the better the distance view in sharpness and for spotting targets in the air and on the ground.
    • The closer the PPD numbers of Vertical and Horizontal are together the clearer the view.
    • Lower PPD means fuzzy distance, less definition of pixels out there and much lower air and ground target spotting opportunity.


Summary for the Top 5
Current Simulation Champ = HP Reverb
  • The clearest view by far currently available for Flight Simulation.
  • Uses WMR Portal and SteamVR. Complex but manageable software sets with some maturity.
  • Inside out Tracking. Well implemented.
  • Documented path to “Best Setup” for this device.
  • Requires a powerful gaming rig and DisplayPort to push all those pixels, and what a view that is!
  • A smaller than you’d like sweet-spot. Still clearer outside of the sweet-spot than most other VR HMD’s inside their sweet-spot.
  • A very light VR Headset, heavy cable.
  • Mid-Level Price at $600 for everything you need.
Largest FOV = The Pimax has this in spades.
  • It is not the clearest, not even close.
  • The software set to drive it is not simple, has variable results per rig, is very immature at this time.
  • No “Best Setup” to get the most out of this device. Consider this one experimental.
  • External tracking is variable in setup and in use.
  • Requires a powerful gaming rig to drive even at the mid-level FOV.
  • The clarity suffers as FOV rises because the PPD gets lower.
  • Very heavy VR Headset, it’s big.
  • Pricy at $800 before you add external sensors for tracking.
All-Around’er Steam Based = Index
  • Medium Clear view for Flight Simulation. You’ll want more clarity soon.
  • SteamVR based. Some maturity in the software.
  • External Tracking. Needs sensors, expensive if you don’t have any.
  • Average Clarity – Average FOV – 120hz is a plus if you can push it.
  • Built for lower-res portal games. Usable as a primary VR device for Simulators.
  • If you don’t have an opportunity to get a Reverb, good second choice for Simulation.
  • $1,000 if you need all the parts.
    Expensive for not being the clearest and not having a feature that’s a “Best of”.
Best New User/Non-Techie = Oculus Rift S
  • Medium Clear view for Flight Simulation, you’ll soon want more.
  • Best at portal games with low-resolution requirements and low polygon count.
  • Very easy to set up and use. Some tuning available via the OTT third-party tool.
  • Excellent Portal Games are available for the platform, mature software, excellent GUI.
  • Very disappointing resolution and PPD vs the competition, but that doesn’t matter as much in Portal Games where it shines. Good text display due to the 3rd sub-pixel.
  • Consider its entry-level for VR, but a good one.
  • At $400, at the lower end of the price point for average results in Simulation.
Best New User/Some-Tech Knowledge/Good Price Point = Odyssey+
  • Medium Clear view for Flight Simulation, you’ll soon want more.
  • Good first user experience for techies in Simulation at a good price point.
  • Text is not as clear as you’d like due to no 3rd sub-pixel.
  • Uses WMR and SteamVR, well-known setup but more complex than Oculus.
  • Famously not comfortable until modified with a new face pad, headphones, top strap.
  • At $299, less expensive than Index by far for similar results though with much less text clarity.

    a 1070ti must indeed be enough on a decent rig for a good Reverb/DCS experience (and also Prepar3dV45 & Aerofly) is my personal finding. I have run them all with a 1060 6Gb and my new RTX 2070 Super config with very good results BUT the Reverb/XP11 combo is a show stopper unless you want to fly without any AA. 4SSAA give a bad jaggy picture and low visuals with a poor 19.99 fps performance so stay away from it. Sadly enough because it became one of my favourites but I think that even a 2080ti can’t handle it in a proper way. I tested with my new build i5-9600K running at 4.6Ghz Turbo clock at the moment and 32Gb 3000 RAM on W10 1903.

    What does the Reverb require in terms of graphics card? Seriously tempted – currently have the CV1. Also is it compatible with glasses? Thanks!

    1. Thud

      Hi, a good question for the folks in the Reverb section of the Discord Channel here. I can’t answer for glasses, they might know. But we have one individual running a 1070ti card for the Reverb. It’s running well, he’s working out a couple of stutters, but it’s great he says.
      I run a 1080ti FTW3 OC’d – and love it. DCS takes more than the average bear in horsepower so I wouldn’t go lower than a 1070ti as a recommendation.

    That’s because there are something odd with the Windows Mixed Reality, SteamVR and WMR for steam software.. The three have various versions ( For the first different versions of Win10 and for the others stable and beta versions ) so we are dealing with a lot of combinations.. I’m sticking at W10 1809 with the beta’s of SteamVR and WMR for steam and I’m getting a very sharpest image ( in fact I received yesterday and now I’m still impressed with the Reverb display quality, was coming from a Odyssey + and never though I am going to get so much improvement )

    I read comments of a lot of people and have seem youtube comparisons between the Rift S, Index and Reverb, and was expecting a little improvement.. Now I can say that a lot of people (including youtubers) aren’t getting the right visuals with the Reverb ( the guilty is MS obviously, not these people ) and because that we are getting all this confusion with people claiming little again comparing Rift S.

    1. Thud

      Thanks for your comments!
      I’ve had great success with the latest 1903 and patches. Enabling the latest Beta Reprojection has made a positive difference. I think Microsoft may have done a better job than Oculus on this one. However keeping it in Beta makes it hard to get to the quality – I agree!

      I’ve found that “WMR For SteamVR Beta” is required with 1903 for the quality. But The “SteamVR Beta” isn’t helpful and I don’t use it.

      DCS wise, ED have said they will soon write directly to WMR and no longer require Steam. We shall see.

      1. sgerat

        Yes, can’t understand why they not enable the reprojection by default. I’m waiting a fix for the reduced FOV and quality for 60 hz mode in order to update to 1903, surely I’m loosing some benefit for the updates but prefer to play at 60 hz with better visuals. Regarding ED.. I wouldn’t hold my breath..

        Congrats for your blog, you have a lot of nice info here !!

    Thanks for the comments! There have been several (10’s) of people who’ve noted their initial setup of the Reverb wasn’t what they expected. I do urge you to go through the setup for the Reverb that’s here, it works! Nearly all of the Reverb owners in JFT-1/CSG-1 have been through it and helped to proof it. Partly it’s DCS, partly it’s the lack of maturity in the VR world. But what the Reverb is capable of can be coaxed out!

  5. Sang Bum Ko

    Just a thought, maybe some info about how vibrant the color of display would be even more grateful. Maybe it’s not that important for simmers or/ not much difference in current gen VR, but i’ve seen people complaining about some of LCD displays for its poor color or brightness range. Anyways, it’s real helpful guide, cheers for that!

    I own the reverb and the Rift S. For some reason I get better clarity with the Rift S in DCS and XP11 than I do with the Reverb. It shouldn’t be that way but it is. I’m sure it has to do with some settings that I have in Steam VR. The Oculus software with OTT is so much easier to use.
