Common Questions
      • “I’m not running DCS via Steam. Do I need all this?”
      • “Does this work for Flight Simulator 2020?”

YES!

    • DCS uses SteamVR as it’s compositor and essentially driver for connecting to your VR Headset
    • Your headset needs this setup no matter the Simulator you will run after
    • For Oculus users, this is done with the Oculus software also supported by DCS
    • There isn’t currently direct support by DCS for Windows Mixed Reality, you need to install and use SteamVR to get started 
    • You don’t need to run the Steam gaming environment with it, you do need this setup with Stand-Alone DCS or Steam DCS
LINK: For the best experience, first, follow the Oculus to Reverb Setup
  • This will ensure you have all of the necessary software to run the Reverb in DCS/FS20 for a First Time User or Oculus transfer
  • Then, come back here and follow the initial setups for the device
  • It is a requirement that you tune your Rig and OS for VR
    • Out of the box Win10 drags simulation to it’s knees
  • Follow the Rig Tuning Guides Closely
    • This is a game of inches, not giant leaps
    • Windows 10 Tuning
    • Rig Tuning
    • Skipping around generally means, oops, missed that, it’s not so great

Not doing the tuning means you’ve left up to 30% of available horsepower on the table and not in the cockpit. Flight Simulation is not your average VR Portal Game when it comes to Rig setup.

Links to Required Software & The Steps to a Good Install
Software for this Walkthrough
      • Windows 10 – [latest version]
      • Windows Mixed Reality Portal (WMR)
      • Windows Mixed Reality for SteamVR
        (WMR for SteamVR  or Beta)
      • SteamVR Release
        • Found in the Steam Store
        • You may need the BETA for some  simulators
        • (MSFS 2020 currently needs BETA)
        • LINK>> SteamVR install
Check Windows 10 Version
      • Click the GEAR for Windows Settings

      • Click SYSTEM

Controls: SYSTEM
      • Scroll down and Click ABOUT

System: ABOUT
      • Scroll down a bit until you see Windows Specifications and the info

      • You need AT LEAST 2004

About: VERSION
Turn Off GAME MODE
      • Critical for DCS and MSFS 2020

      • Enter the SETTINGS: Home screen again and select GAMING

      • In the GAMING screen select Game Mode

      • In the Game Mode screen select Game Mode OFF

Settings: GAMING
Settings; GAME MODE
Settings: GAME MODE OFF
Turn off Hardware-accelerated GPU Scheduling
      • ONLY for the weakest Rig setups or untuned Rigs

      • Tuning far exceeds the benefits of this being on

      • Turn this OFF especially for DCS and MSFS 2020

Control: DISPLAY
Control: GPU SCHEDULING OFF
Settings That Matter
      • If you want all the pixels, then you may not be able to add all the eye candy – horsepower matters

      • But we don’t like the jitter and sparkle around the edges that fit together

      • We compromise, we use tools to strike a balance between enough pixels to see things at a distance, and pixels mushed together for fewer jaggies and stop the sparkly things

      • The in-game tool suite was built for flat screens before 4K or 8K and 30xx cards came around to push pixels through the pipe

      • We don’t need much tuning to clear the view in VR, a bit for fine-tuning 

GPU and CPU  Frametime are the keys to Smooth
      • You can use the built-in DCS Frametime display to show you how much you are degrading your smoothness. However, using the 3rd party “fpsVR” tool available in the Steam Store gives you a better display and more info
      • “Lower Frametime is greater smoothness.”
      • “Once you’re sustaining 35+ FPS, forget about FPS, manage Frametime”
      • In the Frametime graphs
        • Green/Yellow is Good
        • Orange is OK
        • Red is Bad
      • You’ll need to watch both CPU and GPU Frametime and adjust your Super Sampling (SS) percentage and in-game graphics settings to see what configuration keeps you in the Green/Yellow area
      • You may find yourself in a lot of Orange with Red spikes, still smooth but with variable play
        This is where Reprojection can smooth things out
      • There instructions to turn this on and control Steam Reprojection, seen later in this doc
      • MSFS 2020 See the MSFS 2020 Setup Doc for Reprojection
      • If your Frametimes are in the teens range you’re golden
Important Notes & An Equation
      • DCS PD x Steam Video SS = A huge mush of your pixels and drag on your Rig power
        • HIGHLY recommend you set DCS PD to 1.0 and manage the view with SteamVR Per Application SS%

        • The current implementation of DCS PD is not as fine of a control as you get in SteamVR SS%

CAUTION
      • SteamVR adds a multiplier factor of 1.4 based on the individual HMD used when rendering the view

      • See this in action as you move the SteamVR SS slider from 100 to 150

      • Note the resolution of the rendered image it’s pushing is just below the slider

      • Start tuning by setting the slider to 100%

      • Then, with your new benchmarks of FPS and FrameTime, start tuning for clarity of view and smoothness using your tools

 

Where to Apply the Resolution Multipliers

      • For WMR or SteamVR headsets, leaving PD at 1.0 gives you finer control using SteamVR SS% in tuning
      • Using SteamVR Per-Application settings enables this control per application
      • DCS.exe won’t show up for adjustment in the Application section unless it’s running in VR at the time
      • The setup steps follow in the SteamVR section
A Necessary Tool for Tuning – “fpsVR”

@Yomo states and I agree, “Stop chasing FPS”

      • Work for a picture you like and a smoothness in your gaming experience
      • Then stop. Stop being the important part
      • Frametime more equates to smooth a smooth experience than FPS
      • The “fpsVR” Tool available in the Steam Store for about $4 can help you with what your GPU and CPU are doing with various settings.

These are starter settings to get you to a known place to begin tuning.
From here, using the described tools and processes, you’ll start tuning for your unique Simulation Rig capabilities.

      • Example Settings Below
        • These settings change on my rig based on the most recent update and likely the direction of the wind for the day… 
        • NOTE: Anisitropic Filtering should be set to 4x 8x or 16x
          • Without it, the lights and markings on the KC135 tanker are hard to see
        • I have recently set Clutter & Grass to the max with no negative effects
        • I have turned Reprojection OFF currently for the results below

  1. A one stop VR guide. Well done.
    A fellow YouTuber concluded that NVCP has no effect on VR: https://www.youtube.com/watch?v=hipoAXasWeI
    NVCP may in some cases actually cause a decrease in fps, but it’s not completely conclusive. But aside from NVCP, your Win10, WMR, and SteamVR settings are a great benchmark for the VR community.

    • Thanks for this man. I just got HP reverb G2 on a 3070TI I followed the steps here and got a worse picture, stability and performance which frustrated me for days. Resetting Nvidia back leaving and raising the DCS back to 1440P and higher resulted in better experience and visuals were massively improved gfx and stability. My take is have a baseline. DCS PD at 1.0 and SteamVR on Auto worked fine keeping me above 55+FPS average was down to 35 on very low settings. I will mess with the steam setting for now I have a known good config which I think new VR users need to establish. Seems impossible to truly say what your settings should be as some are on 10XX 20XX and 30XX what can be left on seems to very. I am new to VR and have a tendency to min max setups but I gave up and accepted for now It looks good at 1440P with most visuals on like my flat panel.

  2. If the ingame PD is such a drag on performance, why not just leave it at the minimum 0,5 and do everything by supersampling? Is there a quality difference?

    • I’m not 100% sure but wouldn’t setting it 0,5 cause additional processing for downscaling? I think a setting of 1,0 means it’s basically disabled and there is no extra software processing
