Nvidia Sharpening and VR

[Wicked.-]

You are saying that Oculus Rift can now have the graphics manipulated by using nVidia Profile Inspector. However, using the Nvidia control panel will do nothing.

Do all the nVidia Profile Inspector options work with Rift?

 

No, but they don't ALL work for other headsets either. Other than the negative LOD for OpenGL, the settings I've applied work with VR.

So the only 2 settings you've tried are the 2 LOD settings?

Are you trying this on the Oculus HMD or some other?

[Sniper175]

didnt work on od+ but it works on the vr feed that is sent to your monitor, you can see the sharpening on that but not inside the vr headset. Atleast for OD+. Dont need it on a rift s so...

I have tried this settings just for 10 minutes with the Tomcat and to me it seemed worse then before...

Will give another chance tomorrow with more time....

Rift S here

Other Index users said the same when trying -1.5. Try -1.35 and keep dropping the number towards zero and see if you can get a better image. The fact that you’re seeing any effect from changing the setting is promising.

[VirusAM]

I tried -1.5 and -1.35 but didn’t like the effect..

Will try again with -1 and so on...

Yes i can definitely see a difference that is for sure...

I am using pd 1.2 (oculus tray tool) and msaa 2x

[Chapa]

Yes, these settings have definitively positive impact with Rift S.

 

However, I have better results with:

 

- Antialiasing - Transparency Supersampling: 8x Sparse Grid Supersampling

- Texture filtring - Driver Controlled LOD Bias: On

- Texture filtring - LOD Bias (DX): +0.000 / Automatic

- Texture filtring - LOD Bias (OGL): +0.000

- Texture filtring - Negative LOD Bias: Allow

 

I have also set the following anisotropic filtering settings and disable the AF in DCS (nvidia settings are taken into account):

 

- Anisotropic filtering mode: User-defined/Off

- Anisotropic filtering setting: 16x

 

The 16x AF from Nvidia inspector is better than the 16x provided by DCS.

 

 

And finally MSAAx2 in DCS settings.

 

 

With these settings it start to make no sense to use VR supersampling at all. PD 1.2 stay better than PD 1 but.... with the transparency supersampling settings, it is at least as clear as it was with PD 1.4 or more without...

At this point, using PD to reduce aliasing becomes very costly in performances. Even PD 0.9 becomes acceptable for my point oof view (note that I want to play at 80Hz so I accept some compromises).

 

P.S.

 

The new nvidia drivers from today or yesterday add support for sharpening to OpenGL and Vulkan. We will probably have good news for VR in futur driver release.

I go try tonight. Thank you all. :D

[Rosebud47]

Also thanks for this thread. Definetely looks better in the cockpit, but it is also more taxiing on performance at the moment... need to set down PD in DCS to balance.

 

Don´t know, if it has come with today´s patch, the new Nvidia driver or the Inspector profile settings, but the ghosting effect is now significantly reduced on my side.

When looking with external view ( F2 ) to the jet, and moving around the view, there is absolutely no ghosting effect anymore. Before there was always a ghosting effect visible depending on how fast you move the view around the plane.

[Chapa]

If you followed my advice by setting the 8x Sparse Grid Supersampling, it effectively tax a lot on performances. I did know when I wrote my post but I did some measures this afternoon and I discovered that this setting cost (all other things equal) about 30 FPS. These tests was done in no VR mode. Using 2x Sparse Grid SS doesn't change a lot the cost but reduce the effect, so I think the All-in is the best choice.

 

Now, here is the dilemna:

 

As suggested in the picture page 3, you can go with the setting AA_MODE_REPLAY_MODE_ALL and a negative LOD Bias (DX). My test didn't show any cost in FPS for that. But the price to pay is in shimmering. Applying negative LOD Bias increase the shimmering.

 

Personnaly, I find shimmering as annoying as ghosting effect and I decided to stay with the Sparse Grid SS setting. I don't see now any reason to increase the PD for clarity and prefere to reduce at 1.0 or even 0.9 to increase other settings and stay at 80Hz.

 

If you go with the AA_MODE_REPLAY_MODE_ALL setting, I found that a LOD Bias of -0.5 was good enough and do not introduce exagerated amount of shimmering.

 

All of that tends to prove that it exists or will exist solutions to have good clarity without the need of the brute force solution called Pixel Density.

[Rosebud47]

Thanks for your advice to look into the 8 x Sparse grid Supersampling setting to balance the performance.

After downloading today´s patch, I just followed the advices given in here and took a round with some jets.

 

Didn´t looked before into graphics/performance for some time, but recently I´ve changed the new Latency setting to ´Ultra´ and prerendered VR images to 1, what maybe reduced the ghosting... can´t say, which setting does reduced the ghosting finally.

 

For me the shimmering effects are the most annoying things in VR. With some thanks to Wicked too, it is very good, pointing out some opportunities to enhance the graphics for VR with Nvidia Inspector. Have to try out more different settings, to see what fits best for my VR.

 

btw: as just downloaded the newest nvidia driver, I meanwhile got used to set in nvidia driver setting/ display / change resolution / there under point 3. set to nvidia colors and then set the dynamic spectrum to full ( see picture ). This improves the colors a bit.

My friend this is beyond GOLD in a Rift S. Amazing performance and quality top knotch. Thank YOU!!!!:thumbup::thumbup::thumbup:

Think you guys are seeing some sort of placebo effect.

What are you're SteamVR settings for the Pimax 5K+? I know this thread is more Oculus S focused but I use SteamVR with my Index as well and would like to try your settings. I had a Pimax 5K+ and despised it lol but if you can get it running well with SteamVR those settings will probably work well on the Index too.

 

 

Thanks!

Today´s setting in SteamVR is 2724 x 2324 Pitool: @90Hz, Parallel mode, normal FOV.

 

I´ve reduced Sparse Grid Supersampling to 2x, set Nvidia Anisotropic Filter to 16x override application in nvidia driver.

 

In DCS set PD to 1.0 (!) and disabled Anisotropic filtering...only left MSAA 2x in DCS

 

In result it looks really good and is quite performant so far. Shimmering is mostly gone, what is really a small wonder.

Before using nvididas image sharpening and the additional settings we´re talking about in this thread, DCS was close to a shimmering mess when set PD in DCS to 1.0, but now it´s better than before with PD in DCS at 1.3 or 1.4. That´s surely no placebo.

[Chapa]

After some investigations about the meaning and history about the settings in NVidia Inspector (and some performances issues), the following settings seems to do the job well:

 

- Antialiasing - Transparency Supersampling: AA_MODE_REPLAY_MODE_ALL

- Texture filtring - Driver Controlled LOD Bias: Off (very important to set to Off to force the LOD bias setting below)

- Texture filtring - LOD Bias (DX): -0.625

- Texture filtring - LOD Bias (OGL): +0.000

- Texture filtring - Negative LOD Bias: Allow

 

MSAAx2 is counterproductive for clarity. It blurs a lot the picture... (but remove aliasing for sure)

So, I put MSAA to Off and added some PD at 1.1 (sweet spot for my 1080ti to stay at 80Hz and have some margin)

 

The gain in clarity is huge and the counterpart acceptable for me

[Chapa]

@Wicked: I would like to thank you warmly, Wicked, to have share your settings and offer the opportunity to investigate about it. I was already very happy with my Rift S but now it just a lot better.

 

And there is no placebo effect :)

[Supmua]

No definitely not placebo. I can read most of the F-16 side panel texts on my Index with this, couldn’t do that before.

[Rosebud47]

@Chapa

 

just tried your settings and what I could say for sure is, that MSAA2 in DCS really makes the image a nuance less sharp and blurry, while with setting MSAA off, the textures lok a nuance sharper and the image a bit clearer.

 

At the moment I see shimmering quite a lot, but recently I flew the F-16, which is more shimmer free and more optimized for VR than the MiG, which I flew today.

Maybe there´s also some influence of ´selective perception´ at the moment, what causes your eyes to focus on what the mind expects to see. :huh:

 

In nvidia inspector there´s the option Antialiasing mode, which offers much more modes, than the regular nvidia driver settings. Just tested two modes only and the effect could be already observed at the edges of the DCS mains screen in VR. Will try more of these options as there is a lot of Antialiasing variants.

 

The good thing is, that the nvidia settings the image quality could be enhanced, while having performance much more in balance as with DCS PD or MSAA.

You're most welcome. That being said, the settings were recommended to me as well lol. Thanks for testing much further than I did, I tend to get a benefit and then fly for the next week instead going further lol.

 

 

@ Supmua, what are your SteamVR settings with the above NvidiaProfileInspector changes?

[fitness88]

I saw this file posted, does anyone know what the individual lines in the saved games autoexec.cfg do to improve performance?

 

 

Thank you.

[Wicked.-]

Alright, I applied the above settings, then I switched from Video Custom Resolution in SteamVR @ 148% and DCS Application Resolution @ 138% to SteamVR Custom Resolution @ 188% and all other SteamVR SS to 100%. I turned off AF and MSAA in DCS and set PD to 1.0.

 

 

 

Wow.... It is MUCH clearer and the Aliasing is much reduced. Also, flying the Round Table mission and Snowfox missions on our squad server I never went below 45. Regardless of the action it was rock solid 45 or greater.

 

The only thing I noticed odd was my canopy rail would get that watery look when on the ground sometimes. Not often though. The odd thing about it was that my frame rates did not drop corresponding to the wateriness which is what normally causes this. Is this an effect of the Negative LOD? I didn't find out tonight as I was too happy flying my ass off! lol So thanks again Chapa for the diligence in figuring this stuff out!

I don't see any showstoppers that would increase performance to a great degree. But at this point who knows?

Edited November 29, 2019 by Wicked.-

I think we have proven that settings in the Nvidia CP, at least with NvidiaProfileInspector directly affects the visual quality and performance in VR for DCS.

 

THAT, is a damn good thing!
