Jagged/ Shimmering lines in Quest 3

[killerquagmire]

 I've been using the Quest 3 with DCS since launch and have been pleased with the results overall. However, I have been noticing a lot more jagged edges and shimmering in the past week or so on stuff rendered outside of the cockpit. I'm not sure if it's the Quest or DCS as they have both updated recently. Maxing the graphics seems to have no effect. 

Any other Quest 3 users out there having a similar issue?

[av8orDave]

Nope, mine looks as good as it ever has. What GPU? Also, what are your settings? I have a 4090 and run PD in the Quest App all the way to the right, PD in DCS at 1.3, pretty much everything maxed out and hold a solid 72 fps.

Check your settings if the antialiasing had not defaulted to off.

I'm running a RTX 3090. PD at 1.5. MSAA set to 2x,16x anisotropic filtering, terrain and details set to high, everything else set to medium. Hell I even tried maxing all the graphics out and it had zero impact concerning the jaggies. But like I said, I have been running Quest 3 with DCS since October and I just started noticing this recently. It's just jagged edges and shimmering lines on stuff outside when I look out the cockpit. For instance when i was coming in for a landing at an airport tucked between some mountains next to the gulf. The waterline against the mountains was so jagged, it looked ridiculously bad. Also other planes that are beside me on the carrier have horrible jagged lines and shimmering around their wing tips. I will try to get a screen shot up later.

Have you tried DLAA instead of MSAA?

[killerquagmire]

Here are some screenshots I took today. Looks pretty rough for anything a good distance from the cockpit.

Yes but it makes my gauges blurry so I don't use it. I've been using MSAA 2x since October and I've only recently noticed this issue. 

[killerquagmire]

I should also add that I have no issues inside the cockpit. Just seems to be stuff viewed at distance.

Sorry if this has already asked but what are your resolution settings in oculus app? Is the slider pushed all the way to the right? If you use open xr toolkit what is the full output resolution?

oculus app- 4128x2208

xr tool kit 2064x2272 per eye

Those numbers don't seem quite right. Oculus app should be about 5000x2700. You need an overall resolution of 3100x3300 per eye for best quality (panel resolution x1.5). Make sure the slider in oculus app is pushed to the right for max output. Set PD to 1 in DCS and set oculus tray tool (or oculus debug tool) to 1.3. this should then give you a resolution of about 3500 (horizontal). Confirm this in OXRTK and see how it looks in sim. Set DCS to DLAA. You should then have a sharp image and good anti-aliasing (hopefully).

I will give it a shot. Thanks

When you say oculus app, are you referring to the desktop app?

Yes. Push the slider as far right as it will go. Ignore any red warning comments based on your hardware. You have a decent GPU. Also try setting refresh to 72 Hz rather than 90.

Figured out the issue. Apparently MSAA is no longer working. I switched to DLSS and jaggies are all gone now. I have avoided DLSS to this point because I don't like how it blurs my gauges in the cockpit but it seems that has been improved since the last patch a bit. Still a little blurry with sharpening set to 8 and quite a bit of ghosting but it's better than having to look at those awful jagged/ shimmering lines outside of the cockpit.

Just offering some unsolicited advice here, but knock that refresh rate down to 72hz and slide the slider all the way to the right.

I have it set to that already. I just posted a screenshot I found online of the oculus app to make sure that was what he was referring to. 

Any idea how to reduce ghosting with DLSS? 

[PawlaczGMD]

I've had similar issues on Pimax Crystal. Using temporal antialiasing has resolved them. You do get some ghosting though - might just as well turn on upscaling.

I haven't found a great way to reduce the ghosting with DLSS. It's better than using ASW, but still not perfect.

[Qcumber]

To minimize ghosting/smearing you need to push the resolution higher and try to maintain 72 fps with 72hz refresh. I have found that setting the resolution to about 5000x5000 then using DLSS performance reduces the "smearing" a lot. It sounds counterintuitive but try if out and see if it works for you. The caveat is that I use a quest pro and dynamic Foveated rendering. You could try using Quad Views Foveated rendering in fixed mode to help boost performance and maintain a high centre resolution.

Q suggested that you try DLAA instead of MSAA. But you jumped to DLSS right away. You can use DLAA without DLSS. DLAA alone still causes some smearing though.

DLSS and ASW have nothing to do with one another.

One is an upscaling method, the other a motion reprojection method.

That's what I settled on as the best mix of image quality and performance. DLSS was too fuzzy on the cockpit instruments with too many artifacts outside (though performant) so I turned it off. DLAA works very well for me.

I’m aware. I was using the ghosting you see when using ASW to the ghosting you see using DLSS. DLSS has far less ghosting relative to ASW, which sets the standard on my system for bad ghosting. I’m comparing levels of visible artifacts, not upscaling to reprojection.

[killerquagmire]

Good to know. I thought you had to choose something in the next dropdown for DLAA to work. I will give it a shot

Hello guys, I have the quest 3 and a 4080. At the beginning everything was fine but after a while MSAA is not working anymore as usual. I'm trying a new set up. I've read all the topic but I am a bit confused.

about resolution if I use just oxrtk and push the resolution to 3000 or so, why I have to do it again in the oculus app, or doing it again with PD to 1.3 for istance. Is not enough in just one app like oxrtk or PD in DCS? why doing it in more part? is not the same thing?

I usually go with 1.3 PD in the game and oculus app 1x (72 hz) and oxrtk just turbo and no upcaling resolution but I am not super happy.

 

thanks

It doesn't really matter too much where you supersample. The usual recommendation though is to do so in oculus rather than PD in DCS. Overall you need to aim for about 3200 pixels. Things have moved on quite a bit since the post you quoted. The latest version of DLSS (3.7.10) is a lot better. Sharper (but not as sharp as MSAA) with minimal blurring and very good antialiasing.

thanks so much. I will try at home this evening. So is it better DLSS now over DLAA when I reach 3200? anyway I will have a try.

I also understood that I have to use the Foveated Rendering via Quad Views from mbucchia

Do you have a discussion were I can get other informations? I have seen that you are in more than one discussion so I am pretty sure that you know a lot about it
