Improve HMD clarity & sharpness hack Samsung Odyssey

[Gryzor]

Hi, I found a tweak that improves clarity and pixel density in steam VR a LOT in steamvr apps:

Modify the following files:

A)

\\STEAM\steamapps\common\MixedRealityVRDriver\resources\settings\default.vrsettings
and edit the file, changing "renderTargetScale" : 2.0" (instead of 1.0)

B)

\\STEAM\config\steam.vrsettings
and edit

"compositor" : {
"renderTargetMultiplier" : 2
},

instyead of 1.


With this hack, you will reach the same image quality in SteamVR apps as you have in cliffhouse. Its incredible the difference of quality, now and before is like the night & day. I hope DEVs could implement this in a easier way.

Came here to thank you for this post, the guy complaining that this is placebo is obviously blind.

Rendertarget scale seems to depend on the game you are using - for example in Doom VFR, Subnautica or Fallout4 i see no real difference. Haven´t tried any other games, but for those i really tried to see a difference but couldn´t notice any. This was on an Odyssey+ with 200%SS in Steam.

[Rocco]

in fallout 4 vr you shoould see a difference for sure.
Check if you have 200 SS under Video in Steam vr

Trying to compare apples to at least another flaovr of apple question and a comment...

...@ Rocco and others with good results

Questions needing answers for reproceability of testing:

SteamVR (Release or Beta):
WMR for SteamVR (Release or Beta):
Graphics Card:
Graphics Card Driver version:
Graphics Card Video RAM:
Is WMR for SteamVR motion reprojection enabled (yes/no, auto/motionvector):
Is SteamVR Video Settings set to auto or manal (yes/no, % value):
What game did you see the improvement in and what value is its specific Application Resolution Adjustment value set at (% value):
Are there any custom external video settings such as ones found in video card control panels (yes/no, settings):
In game video settings:
Is Nvidia SLI, Nvidia SLI Anti-Aliasing, AMD CrossFire enabled:
Is SteamVR's developers Advanced SuperSampling enabled (yes/no):
Framerate from SteamVR or fpsVR in game:


Comment:
Lots of systems would have a very hard time getting and maintaining 90fps in the HMD or even 45fps with WMR Motion Reprojection when overriding the SteamVR Video Application Resolution to 200% which can affect all games. Without a manual override, SteamVR will auto detect and set a value based on the results which can vary impacting your results. Ideally you are setting this manually to 100% and changing the SteamVR's Video setting to 200% per game to prevent this issue.

Auto SS value is chosen based on your HMD standard resolution at 100% and used video card.
For instance for Vive it's

GTX 970 = 100%
GTX 1060 = 100%
GTX 1070 = 130%
GTX 1080 = 180%
GTX 1080Ti = 200%

There is no any additional real time dynamic adjustments.

Actually i do notice quite a difference betwenn 100%SS and 200%SS for Fallout 4 VR. What i meant was with the mentioned games and already 200% SS in Steam i do not notice any difference between Rendertarget Scale 1.0 or 2.0.

Elite Dangerous
Not seeting a difference when setting to 2.0 and SS @ 200% versus 1.0 and SS @ 200%

Is WMR for SteamVR motion reprojection enabled (yes/no, auto/motionvector): Yes, motionvector
Is SteamVR Video Settings set to auto or manal (yes/no, % value): yes, 100%
What game did you see the improvement in and what value is its specific Application Resolution Adjustment value set at (% value): Elite Dangerous, 200%
Are there any custom external video settings such as ones found in video card control panels (yes/no, settings): no
In game video settings:
-AA: SMAA
-SS: 1.0

Is Nvidia SLI, Nvidia SLI Anti-Aliasing, AMD CrossFire enabled: Yes, SLI, not functional in VR
Is SteamVR's developers Advanced SuperSampling enabled (yes/no): no
Framerate from SteamVR or fpsVR in game: Barely averaging 35-45fps in stations with WMR Motion Reprojection enabled to simulate 90fps.

@Andrew_WOT

To be clear, I'm not stating Auto SS is dynamic in SteamVR for WMR during a game but appears to be based at time of SteamVR launch or detected video card driver change and is based on an average of results, then set. The range, if not manually set to 100%, can vary greatly from 100% to 125% for example and is prior to a game even launching which can impact a games specifically set Application Resolution Adjustement ending value.


In my case, here are my averages with SteamVR wanting to set my base video SS to ~118% vice overriding to 100%:

"GpuSpeed" : {
"gpuSpeed0" : 495,
"gpuSpeed1" : 462,
"gpuSpeed2" : 477,
"gpuSpeed3" : 460,
"gpuSpeed4" : 476,
"gpuSpeed5" : 445,
"gpuSpeedCount" : 6,
"gpuSpeedDriver" : "25.21.14.1758",
"gpuSpeedHorsepower" : 468,
"gpuSpeedRenderTargetScale" : 1.1799999475479126,
"gpuSpeedVendor" : "NVIDIA GeForce GTX 1070",
"gpuSpeedVersion" : 2
},

o + user, I confirm the extreme improvement with the 2.0 and 200% settings. I use it since october and recommend it to my friends who are amazed themselves. all other values ​​as well as supersampling and antialiasing within the application make the picture blurred. successfully tested with skyrim, elite, doom vfr and many other games. Unfortunately, in some games the setting does not work. I'm trying to figure out why ... wmr devs should definitely make an announcement. Here wmr stands out clearly from other headsets, as the sharpest picture is actually achieved without costly image enhancement.

So happy about my placebo that i never would change the headset at this time... and I tested and used them all, included pimax 8k and 5k+...

Thanks @Gryzor. Hope next WMR update will make it default

I believe you, but I don't see how that post confirms much.

[Kyokushin]

Thank You, Gryzor. Its good devs are aware of it.
Thanx to You i can enjoy better quality on my O+. Good job.

Maybe someone can help me understand something - i tried something with subnautica today. I raised the SS in Steam to 500%. I have the version from the epic store and i figured, that changing the values in steam vr are applied instantly - so no need to restart the game. I was quite surprised to see a huge improvement in sharpness compared to 200% Steam SS. Of course nobody wants to play a VR-Game at about 20 FPS.
But - my question is, how can it be, that even if the physical resolution of the Headset (Odyssey+) is constant, that SS makes such a huge difference. I understand that supersampling a picture and then downsizing it to the displays resolution can help with aliasing artifacts, but the gain in sharpness is quite dramatic. I thought in theory driving the display at it´s native resolution (pixel per pixel perfect) should give the best picture (concerning sharpness) achievable... Obviously there is more to it.

Did you try DSR on flat screen?
