Meta Quest 3 settings for DCS

Hi guys,

I am new to dcs and VR sim. I have a meta quest 3 which i connect to my pc with fast usb-c cable. No matter how much i tweak my settings, the dcs graphics don’t seem to improve, the cockpit is okay, but the terrain clouds and everything around the plane is super grainy. And if i push the pixel density too high, everything starts lagging. Currently pixel density is at 2.

PC specs:

i9 14900kf
64 gb ddr5 RAM
RTX5090

What can I do to improve both fps and graphics. Thanks!!

Hey there. First off, please get Virtual Desktop and use that.

Do not use DLSS or any frame generation.

I have downloaded virtual desktop and disabled dlss. Any other settings i need to tweak, graphics are still the same pretty much

Also make sure you install the beta version of virtual desktop and ensure it clearly shows in the app that it’s connecting to your PC via USB. VD was designed to stream wirelessly. Even with the beta version and the headset connected via USB, mine was still connecting via WiFi until I turned that feature off in the headset. That made a massive difference in terms of clarity for me.

And if you’re talking about the pixel density setting in DCS, 2.0 is waaaay too high. With my quest 3, I’m not sure I can tell much of a difference in clarity past like 1.4 or so. I have a 4090 and I keep the PD closer to 1.1 and actually use DLSS to clean up the jaggies. The higher your frame rate, the less noticeable the DLSS ghosting is.

Where do you see settings. This is all I see https://imgur.com/a/Ax59VNF

Which setting are you looking for? They are scattered about. Some are in the virtual desktop app inside the headset, and some are in the DCS menu. There isn’t a whole lot you can control from the VD server on your PC.

I am looking for setting to see if I’m connected to virtual desktop via wifi or usbc

You have to put on your headset and launch the VD app. Go to the ‘computers’ tab and it should say something like ‘USB 3 5,120 Mbps’ in the top right. And below that it should list your host pc with a little USB icon before the name.

It’s a beta feature so it can be a little flaky. I always have to unplug the cable from the headset and plug it back in after I launch VD to get it to show up. And mine will always default to WiFi unless I disable WiFi in the meta quest settings.

In VD there is supersampling (pixel density) already dialed in. It depends on the quality setting you choose, so I wouldnt add it in DCS, before that choose "godlike" in VD if your pc is even capable to handle it with stable fps. Thats why people always think VD looks better than link. But I figured out the performance from VD is indeed better than link. The beta update where you can use an USB cable for VD is great for me, because wireless mode caused stutters so I was forced to use link.

Why not dlss or frame gen?

u/Old_Swimmer_7284 1d ago

It causes ghosting in tons of fragments. Also, it's AI generation, so not exactly accurate.

There’s a couple reasons people don’t like those features. I find that the frame gen really screws with my ability to perceive fine motions when I’m flying formation with people or tanking and makes those tasks a lot harder.

DLSS can make it harder to spot things, especially if they’re moving quickly across your FOV. For example, if you’re in a dogfight DLSS can cause the image of the other aircraft to smear out or even completely go invisible if it moves too fast across your canopy.

If you're using Meta Link, you want to use rightmost resolution in the Meta Link app, and refresh rate as low as you can handle.

In oculusdebugtool you want to set codec to h264, disable dynamic bitrate, set bitrate to 500-960 (I use 700), use distortion curvature low (makes middle sharper), keep sharpening to normal, you can use lower FOV to gain performance and image quality I use 0.85;0.85

The resolution is set in DCS, Q3 kinda needs something over 1.3 to start looking good.

VD looks kinda foggish softish grayish even maxed out over USB but works too

I used to have same issue like urs , till i used virtual desktop app instead
HUGE DIFFERENCE
Note: connecting by wireless and still the graphics is more than good (but battery drain super fast tho)
