Quick Tips
Why do I have screen stutter, ghosting…etc.
- Clear out the Shader Caches in Saved Games
- Nvidia CP Setup needs reviewing
- Ghost Monitors need to be turned off
- Game Mode is on – Turn it OFF
- Reprojection is OFF you may need to turn it ON
- My software isn’t updated
- Windows 10 isn’t tuned for VR
- My rig hasn’t been tuned or OC’d
- USB Power is low or too many devices in the chain
[get a USB PCIE Card] - Too many monitors on your video card
Tools to Make it all Work
- DDU – Start with clean drivers
- Easy to do, but follow the directions closely and plan ahead with your chosen driver version downloaded before you start
- fpsVR – FrameTime and FPS
- Performance detail Desktop and VR views
- Process Lasso – TBD
- ..to be continued
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
- 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.

Check Windows 10 Version
Click the GEAR for Windows Settings
Click SYSTEM
Scroll down and Click ABOUT
Scroll down a bit until you see Windows Specifications and the info
You need AT LEAST 2004
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
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
Settings That Matter
Anything other than native resolution is a degraded picture
If you want all the pixels, then you cannot add all the eye candy
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 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 or more likely 0.7 / 0.8 / 0.9 and leave it there
Use the settings in SteamVR to enhance your pixel density
The current implementation of DCS PD is a massive drain of GPU/CPU
Using SteamVR as much as you can for tuning will save you cycles for gameplay and turning on more eye candy
CAUTION
SteamVR adds a multiplier factor of 1.3 or 1.5 or more, 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 rez displayed as close to your native rez as you can
Then, using your new benchmarks of FPS and FrameTime, start tuning for clarity of view and smoothness using your tools
You need to decide where in the Steam Settings to apply the SS% factor
- Adjust the SS in Video SS (Global) or in the Application section specific to your game in the SteamVR Application Settings
- If you have many games with different SS% needs, make adjustments per Application
- DCS.exe won’t show up for adjustment in the Application section unless it’s running in VR at the time
- Applying these settings in SteamVR has less of a drag on your CPU and GPU than using the PD Slider in the DCS VR Tab
- PD does essentially the same thing in DCS but not as efficiently
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.
DCS Initial 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
- System Spec
- i9-9900k@5.2
- EVGA 3080 FTW3 Ultra
- 32 gig 3400 RAM
- M.2 Drive
- Reverb G2
- Results in MP
- FrameTime: High teens to low 20’s
- FPS: 55+ maxing at 90
- Small dips around busy airfields briefly to 45 fps
- No Stuttering
- No Frame Lagging
- Example Settings Below
SteamVR Settings
General Setup SVR
- Settings Menu/Video – App Rez/Custom (Native or best performance if NOT managing by application)
- Settings Menu/Applications – DCS.exe Custom Rez @ Native Headset Resolution if you choose to manage by app.
- G2 to 50% / 90% /100% OR as recommended by the white marker
- G1 to 100% / 125% / 145% OR as your best visual/smoothness dictates
- (DCS.exe only shows here when it’s running)
- Developer – Enhanced Super Sampling – OFF/ON
- Try OFF first. When stable and smooth in flight, try changing it to ON
- Adds additional smoothing to antialiasing, but may induce artifacts or lag
- Either setting may make a difference based on your Rig capabilities
Detailed Setup SVR
- Chose the Bars for the Menu
- Select SETTINGS
SVR General TAB
- Note the Resolution Per Eye Setting
- Here the resulting resolution at the 50% setting for the Reverb G2 is close to the native G2 resolution

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?
