Another win for Fholger

[Sr.]

This is actually working. Long story short, it allows you (me anyway) to run SteamVR SS at 100 and MSAA 4x with no frametime loss.

Here are the no nonsense EASY instructions. It's a must.

1. Download the ZIP file from here. https://github.com/fholger/openvr_fsr/releases

2. Go to your DCS folder and into BIN

3. Find "openvr_api.dll". Rename it to "openvr_api.orig.dll"

4. Extract the ZIP files from the above download.

5. Copy and Paste those files into the DCS/BIN folder.

 

My current config file:

 

{
  "fsr": {
    // enable AMD FidelityFX Super Resolution
    "enabled": true,

    // Per-dimension render scale. If <1, will lower the game's render resolution
    // accordingly and afterwards upscale to the "native" resolution set in SteamVR.
    // If >1, the game will render at its "native" resolution, and afterwards the
    // image is upscaled to a higher resolution as per the given value.
    // If =1, effectively disables upsampling, but you'll still get the sharpening stage.
    // AMD presets:
    //   Ultra Quality => 0.77
    //   Quality       => 0.67
    //   Balanced      => 0.59
    //   Performance   => 0.50
    "renderScale": 0.75,

    // tune sharpness
    "sharpness": 0.75
  }
}

didn't work for me last night. got an error in the log and the shimmering was absurd. I WANT this to work really bad. haha

Had some more time to do better comparisons today. I think you're right about the shimmering. And while it was nice to be able to run 4x MSAA, it's kind of a trade off. Going back to stock for now.

Try setting the sharpness closer to 1.0 that basically took care of the shimmering for me

That's the ticket 

[Gun Jam]

I gave this a try and was unhappy with anything under 1.0. using 1.0 reduced shimmer and let me run my G2 at 100% SS in steam. Things were for sure sharper but they were over sharp and it started to generate ISO noise in the image. Using 4xMSAA and 100% SS gave what I would consider a good improvement in overall quality but caused too much loss in frame time I was down about 10fps with a 2080ti when close to ground. Between the loss 10fps and the iso noise (over sharpened) I went back to using just the VR shader mod, 70% SS no MSAA. This is almost a win in my case.   

[Baldrick33]

I didn't see any real improvement using this. I tried lots of settings but the loss in quality and gain in performance seemed similar to simply reducing the SteamVR SS.

Does Mustang's clear sky still work?

 

Last times I've tried it, I get an error on DCS started that it's was "deprecated" or something to that effect.

[speed-of-heat]

Don't know the flat shadows mod is depricated though

[speed-of-heat]

Release Candidate 1 is now available

[Tshark]

Showing the same gains on frame times.  Little bit more shimmer, but worth it.

[speed-of-heat]

yep the numbers i have are basically margin of error changes:

[Sr.]

Encouraging to see he's working on it.

[speed-of-heat]

There seems to be a big that overly saturates the gamma in the latest RC1 build i have rolled back to the alpha 

[zildac]

I must be doing something wrong because with this enabled and reshade obviously disabled the shimmering and aliasing is awful (Caucasus ready on the ramp). If I look to my right at the other F18 parked on the apron it's wobbly mess I’ve tried with MSAA OFF and set to my normal 2x. It's working as the log file looks good, but it looks horrendous.

[RealDCSpilot]

@zildac No worries, you're not doing something wrong. I'm on the same boat, tested it again and again. Simply going back to classic SteamVR SS settings and MSAA gave me same smooth performance as before and superior image quality compared against Fidelity FX FSR.

[speed-of-heat]

hmm not sure what to say, the shimmer is "the same" for me with the mod on or off, the reshade mod and this do not play nicely together and with them both on it has more shimmer than a hula-hoop dancer...

[speed-of-heat]

RC2 Just release fixes the over saturated gamma.

Alpha definitely the best so far. 

[zildac]

Yeah it's strange, it almost looks  as though the res has been dropped and all antialiasing turned off. I'll have a root around to check that there isn't some remnant of a previous mod, I already did a "long" repair. I am using Bartheks Caucasus but that shouldn't affect the actual aircraft model "shimmers"

The worst "shimmering" I'm seeing is in the cockpit MFDs (FA-18). They go from very readable to "WTF have I done?!"
