Has anyone tried this?

Anyone see any improvement?

I'm not sure which headset you have, but with MR off that micro-stutter is caused by the gap between the lenses.  This is why when you look ahead you don't see it, but as soon as objects are travelling across the lenses there can be a lag which is perceived as a stutter.  Your brain just blurs things that do this across your eyesight.  With MR on you get the wobbling affect which is a little less noticeable when you set OXR to 75%ish, but none of what I call the "90 degree" lag.  Personally, I find it easier to get used to the lag now that I understand it.  I've turned down the game settings just a tad, set OXR to 75%, and set the world scale and field of view correctly in OXRTK.  On my 3080, this is a solid frame rate above 30 if not higher.  No, scaling, sharpening, or anything else required for me.  I find less is more in VR.

I have G2, see my setup in my signature. I am having stutters without MR because I can not everywhere reach full frequency. Many places I have 90FPS now and that looks okay, maybe I then still have the microstutter you mention, I am not sure. But in places where the FPS drops because of CPU impact, I see hesvy stutters. Even with 60-70 FPS. I see the most stutters when I fly low in the hog, look over my wing and do some quick wing rocks.

What do you mean by setting world scale and fov 'correctly' in the toolkit?

World scale override  The in game setting for IPD under the VR tab is similar, but I haven't tested this yet.

Field of View I have mine at 90. 

 

Okay yes I know what they are but wondered what you meant by correctly.

Made some further adjustments trying to get both stable view inside the G2 and in the recordings.

- Reprojection OFF (having it on gives smooth view inside G2, but heavy stuttering in recordings)
- Custom render resolution 50% (lowest I can stand inside the G2)
- FPS locked 55 to stabilize 
- OBS NVENC AV1 Encode, Remuxing to MP4 for Resolve 
- New version of Jabbah's OBS Mirror (champ!)
- Using Fred's OpenKneeboard

I find it weird that you have to have the custom render resolution down to 50% to get the game to be smooth. I have a 4090 and a Ryzen 3700X with 32GB of 3600Mhz ram.

My game is pretty stable, locked at 55.

Are you using native openxr or using the old method of copying the dll into the bin folder?

I could not play DCS with 70% render resolution with my old card. Did not liked the way inside. I bought rtx 4090 special for 100% render resolution. I get good performance with 100% and fps locked at 55 + Foveated Rendering quality/wide and turbo mode.

Custom render resolution 50% for rtx 4090 is not the way.

Thanks for pointing this out, I'm also using turbo mode and using the old dll for opencomposite. The native support just didn't work well for me...

try also Foveated Rendering quality/wide. you don't have to copy dll. if not use native, just use the app and select dcs to not use steam vr as default.

I copied the dll to use opencomposite. I don't know why, many people are claiming that native is looking great for them. For me, it just looks muddy and I can't stand it 😞

1. same quality

2. you don't have to manualy copy dll for every update. this is a very old method

 Set runtime to OpenComposite

(Which connects DCS to OpenXR) - On first startup it needs to download DLL's. Wait for that to complete before going to the next step.
NOTE: The app configuration screenshot below is post DCS launch. Initially, you will likely see a blank page. This is normal

  • The application allows you to select which individual games you would like to connect via SteamVR and OpenComposite and comes with a built in update utility! Just run it every now and then to check for updates - Neato!

I just got a 4090 and 13700k plugged it in set every thing to max except 1 shadow setting and its hitting from 55-72 using the default instant action F18/Syria free flight.

No tweaking nothing and man is it smooth

try to cap your fps. because when you jump from 90 to 72 fps or from 72 to 50 fps is very nasty( at least for me). i choose stable 51-55 fps with a lot of overhead than just to see 90 fps sometimes(very rare in free flight at high altitude)

Posted

 I do get 90fps on every SP mission or campaign,  using hp reverb g1 and balls to the wall settings(5800x3d + 4090). But,if I  try that config on a mp like grayflag or enigma's server... can't even get more than 20fps sometimes.

If you're on MP server or hosting a mp server, the fps loss is so high is not even worth it for now in vr (I'm talking about very populated and heavily scripted servers). I even used my old riftS and low settings but DCS is very CPU bottleneck, so I ditched VR for now on MP servers.

That's why MP with VR, no matter your hardware, you can't have max settings. We'll see how this will improve once we get multithreading and dlss.

I am currently using native Open-XR. I have things turned down because I mainly play in MP and if I keep things at 100% it is a stutterfest when I have Motion Reprojection OFF. I need MR turned OFF, because otherwise my OBS recordings show crazy stutters. So it is tricky to find a balance where things are good inside the headset and inside the recording. I sometimes lock my frames at 55, but I mainly do this at places where my FPS is close to 55. When I fly SP I have it disabled because this gives me more smoothness.

I agree it is not the way, but it is currently the least bad choice in order to get both acceptable visuals inside G2 and in my recordings. I used to have Foveated Rendering on when I was using a 3080, but I disabled this because when I look back at my recordings it looks horrible. Inside the headset it is okay, but on screen it is bad. Will give Turbo Mode a try. I might reintroduce FRR, but not sure if this will give me a big noticeable improvement performance-wise.

Yes I have similar experience on our own MP server, albeit a bit better FPS, but still very noticeable impact. My FPS sometimes just drop from 90 to 45, sitting still cold and dark and looking around to certain areas on the base. When we have flight night it is worse, especially with a couple of AH-64's in the air. This is why I currently turn my render resolution way down to offload my CPU, which still gives me an acceptable experience inside the headset. The custom render resolution is also an easy knob to turn.

unlikely as the DLSS 3 uses  backward predition (interpolation between two   already  generated  frames) so add unacceptable latency for VR...

Motion Reprojection alghoritms use forward predition (syntetic frames from already generated frames)

DLSS is not for vr. See problems in Msfs 2020. Every mfd and text on mfd will be blurry.

 

I may well be wrong but from what I understand you can set certain layers/areas/textures to be excluded from the upscaling which helps prevent the blurriness.  In MSFS this was the case with the blurring.  It could be pointed out that currently with NIS/FSR upscaling via openxr toolkit the MFD text clarity doesn't start to suffer really (in my case) till you're below around 65% scaling; I would hope that DLSS when implemented will be an improvement on this 🙂
