VR setup - My best advice to you and........ I guarantee it.

[Heli Shed]

Trust me on this..........  this will make a huge difference for you if you are struggling to find what is right for you. Like many of you, I've been around this community for many, many years and one thing we all have in common is the constant drive for max performance from our systems so that this great sim looks the best it can be.  We do likewise for VR!  But......................  is there a 'best set of parameters?'.

Horses for courses perhaps.

This is my view.  If it doesn't help you, I'm very happy to work 1:1 to get it the best you can. 

Good luck!

So basically on the Quest 2 you set the HZ @ 90 then set the ASW at 30 well that is still ASW is it not?? it just limits the FPS too 30?? I Could try it too see for myself but I have a G2..

 

I can set the HZ to 90 but how will I lock the ASW too 30hz?

 

I am sure this works but it still uses ASW..

[Heli Shed]

As long as it's a multiplier ie, the VR refresh rate divided equally by debug refresh rate, then it will work fine without ASW. Use oculus tray tool or better still the debug tool to ensure that the FPS is fixed - by setting 30hz in Debug or tray tool you are essentially fixing the frame rate - works fine mate.

 

I have just added timelines for easier navigation of this 17 minute demo video.

saving it for later, thanks

[Thanatos31]

Will /Can this work for the reverb ? 
what Tools / settings to use then? 

[VR Flight Guy in PJ Pants]

I tried it with Quest2, it gives constant 30 fps +/- 4,  even in Syria map. I have not tried any MP or heavy scenario. But it  very sharp, no strange screen warp, not much stuttering but still have ghosting from time to time. I would say this is very enjoyable.  Thanks for taking the time and sharing with us.  The downside is that I don't use OTT which wrecks the performance and changing ODT every time the computer boots is not a joy.

Good advice - I’ve been using the same mindset since I got my oculus. For those of us with hmds that don’t have 80 or 90hz refresh rate (quest 1, for me, sadly, though it was under £100), you can just turn ASW off and then use Nvidia or amd control panel to limit max FPS to the appropriate factor of your refresh rate. I set mine to 36fps, half of the 72hz. And that’s just perfect.

With my current settings, on a 1060, I get about 50fps in single player over Syria and slightly more in Caucasus. So I limit to 36fps and rarely if ever dip below, and it’s solid, no artefacts, no weird shimmering/melting trees etc, even at 650kts and 100ft in the hornet.

The only things I haven’t decided on are whether to have vsync off or on (or fast, set in NCP) and the best choice for low latency mode.

well with the g2 limiting the fps in nvcp seems to have no effect?

[rubbra]

Oh, that's odd! You have hit apply, and then restarted DCS? You could also try Adaptive vsync, half refresh rate?

I find vsync fast an NVCP essential for flying at half or full refresh rate. It just makes the whole experience cleaner, can't rely explain it but I have tested it several times across a couple of headsets and can't fly without it.

Interesting I’ll give this a shot and see if I notice anything 

[Gogojuice]

What version are you running.  

Mine has a setting for clouds.  I don't see that one on yours.

 

Is this current?

From the video description:

I remastered this video I done about 6 months ago now. I now have an RTX 3080ti but I still fly in exactly the same setup as I did for the 1080ti - no difference. Point is, set it up right, watch the video and VR will be transformed for you, it was for me. This is using Oculus link (cable btw).

So, yes, it is DCS 2.5.6 but advice should still apply for current version.

Just checking, this is the Oculus Debug Tool setting:

I am making a batch file so the setting loads every time I start up the computer.

I cant get 30fps with debug tool. If I choose disabled I get the highest possible framerate.

Perhaps but highest possible framerate != best experience, at least not always. I get a better experience limiting frame rate to a factor of my HMD’s refresh rate (in my case 36, half of the 72hz of my Quest 1) than I do if I am running at 50fps.

Thanks, I think you are saying highest possible frame is mostly the best.. This is not my experience, I have flown like this achieving frame rates of 40-80 (80hrz) with no ASW and, to me, this is a horrible experience. Not smooth. I current lock to 40fps and ASW on and its seems buttery smooth. I can sometimes get the full 80fps which is really great but its only a small amount of the time and the flicking between on and off isn't very nice so I lock to 40 with ASW. I'm interested in trying this 90hz and 30fps with ASW off, but from my own 2yrs DCS VR experience this will be horrible. Not really sure how the 30hrz  in OTT is applied if it isn't an option within the debug tool?

Not all,  I’m saying that the highest possible frame rate is often NOT the best. 

 

oculusdebugtoolcli has options for:

 

asw.Clock30

asw.Clock45

asw.Clock18

asw.Auto

asw.Off

asw.Sim45

asw.Phase45

 

Which is how OTT sets them.

 

[VR Flight Guy in PJ Pants]

I use the server:asw. commands too. It works fine if I type them in.

.

However, when I put the commands, I have tried "server" prefix ones, in a file and run it through -f option, it does not work some how.

 

One thing, if you type Server:asw.Clock30 (command is case insensitive), the ODT still shows ASW disabled, but typing server:asw.mode shows it is running at 30fps forced.

I dont know you get good results setting at 30hz ASW with 90hz.

 

That way is supposed you get two interpolate frames from every real frame and if, aiready with 45hz you get some graphics glitches from ASW things just gets way worse whith 30hz.

 

I get WAY better results with 45hz

The video is about 30fps without ASW. Apparently this is smooth, I haven't tried it yet myself. 

[draconus]

I only tried 45fps, ASW disabled with ODT (no NVCPL changes) and I liked the experience - more smooth and no ghosts but unfortunately headtracking itself is lower fps too now, and that certainly is not what I like.

Oh ok. Didn't know this. How do I get ODT to use these? Is oculusdebugtoolcli a command line version?

Yes it is. Same folder as ODT.

 

You can't get the GUI version to use them.

 

 

[VR Flight Guy in PJ Pants]

  

Here is an example how you can use a batch file to set the Oculus Rift/Quest every time you start the computer, based on the ODT setting I posted above:

 

In the Batch file:

"c:\Program Files\Oculus\Support\oculus-diagnostics\oculusdebugtoolcli.exe" -f setoculus.txt

 

for the setoculus.txt:

service set-use-fov-stencil false
service set-client-fov-tan-angle-multiplier 1 1
service set-force-mip-gen-on-all-layers true
server:asw.Clock30
exit
