The consolidated information here is made possible by the pilots in JTF-1 and in the DCS World community whose curiosity and dedication to our hobby lead the way to the best experiences. This is their effort consolidated into a workable document.

We hope you can benefit from the collective brainpower.

The Steps to a Good Install

REQUIRED SOFTWARE for this WALKTHROUGH

How do I know which version of Windows 10 I have?

Click the GEAR for Windows Settings

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 1903.



Which Settings Matter – A Primer

[NOTE SteamVR Screenshots have NOT been updated to the latest version. There are changes to the GUI. BUT, the info is the same]

Anything other than native resolution is a degraded picture.

If you want all the pixels, then you cannot add the eye candy. But we don’t like the jitter and sparkle around the edges that fit together. We compromise and we have good tools to strike a balance of pixels to see things at a distance and pixels mushed together to see circles and stop the sparkly things. This in-game tool suite was built for flat screens before 4K or 8K and 2080ti cards to push pixels through the pipe.

We don’t need much of it in VR, though some for fine-tuning.

GPU and CPU are keys to Frametime

You can use the built-in Steam 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.”

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 is a file change that allows you to turn this on and control Steam Reprojection, seen later in this doc. If your Frametimes are in the teens range you’re golden. Try not to run with lots of Red.

Important Notes & An Equation

DCS-PD x Steam Video SS x Steam App SS = A huge mush of your pixels and drag on your comp power.

HIGHLY recommend you set DCS PD t0 1.0 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 other, based on the individual HMD used, to the rendered view. See this in action as you move the SteamVR SS slider from 100 to say 150. The resolution of the rendered image it’s pushing is noted just below the slider. Get the rez display here as close to your native rez as you can. Then, using your new benchmark start tuning for clarity of view and smoothness using your tools.

You need to decide where to apply the SS factor

Adjust the SS in Video SS (Global) or in the Application SS section specific to your game in the SteamVR Application Settings. Not both.

Both is a multiplier and will zap your horsepower ASAP.

Applying these settings in SteamVR seems to have 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.
