Oculus Quest (Santa Cruz)

Where I'm going with it though, is if the quest display can support that level of sharpness, which it clearly can, then when being driven by the PC source then it should be possible to make things sharper. Its just figuring out how. I was playing with steam vr's supersampling settings the other day but i don't have a powerful enough GPU to experiment fully with it. And also I assume the wireless bitrate must also constrain the display quality.

I believe the issue is there is a bandwidth limitation with decoding video in the Quest's onboard chipset.

However with Oculus Link you can tweak the resolution and image quality, and get better results if you have a good GPU:

I've just tried the latest Virtual Desktop beta, and the image quality is definitely sharper than the default Link quality, but for me Link feels smoother, presumably because it's hard wired and the frame times can be more consistent.
 
@Ravenger thanks for that. I'd read similar elsewhere but nice to have a link directly to Oculus on the topic.

I'm struggling to see how VD can be higher quality than link though. I haven't experienced it for myself yet as waiting for a cable to arrive, but VD is limited to 100 Mbps bit rate and the max I'm seeing as confirmed yesterday is about 80 Mbps which will include data as well as video. I've read that the Quest decoder can run at 150 Mbps so should be plenty of room for improvement if the GPU can handle it. A USB 3 connection running at 5 Gbps should be able to transmit the max video bitrate of 150 Mbps as well as the data.

This is what I meant.

My PC network rate was maxing out at 54Mbps when doing the suggestions above whilst playing saints sinners, wihch I thought was a bit strange, and swapping out the cat5e cable got it up. I saw 85 at one time, but can not replicate it and now seeing max 70. My PC isn't the strongest, hitting 7.2 on the steamVR test. So I wonder whether lowering the graphics settings on either S&S, or VD would help for the purposes of testing max network thruput.

Trying tonight, I'm now see 86.xMBps,in VD oftem when I switch quickly from saints&sinners to VD, and also seeing 32Mbps before running the game. The reboot after sorting out the PC network connection seems to have improved it.

Is your wifi signal compromised at all, either by walls or by other devices using some bandwidth?

No VD is showinng 866mbps connection, and I'm only a few feet away from the router.

I'm out of touch with wifi realworld transfer rates. On such a connection what's the expect real-world thruput. I'm guessing I'm pretty close ?

Having completed saints&sinners (great game I thought thanks to those on here that suggested it), I'm thinking about Alyx. My PC gets 7.2 on the steamVR. should I expect Alyn top be more taxing on the PC than saints ?, just wondering if I should invest, only for my system to be too slow.
 
@tangey this is what I get, 6.8. That's on an RX480 which is 3.5 years old now. If Steam puts that into the green and says its ready and you're getting 7.2 then I'd say that's fine?

Re the bitrate over wifi, youre close to the max as am I. VD is limited to 100 Mbps.

Ignoring the portability and wirelessness, and the sound quality. Is the quest a worthwhile upgrade from a CV1 for a couple of space sims? (lots of blackness)

What you need to remember is the Quest to play PC games the image is streamed to the Quest. So in theory even though the Quest has a better resolution the CV1 will look sharper. If you are thinking about playing just PC VR games then you are probably better looking at one of the dedicated PC VR systems. If you want a good mix of both PC and untethered gaming then the Quest is a good option. Maybe someone on here who plays Elite can add to this but just for PC based space sims not sure whether it would be the right choice.

Just wondering myself whether to try Elite again I bought it really early and I could never get the hang of it, too frustrated with not knowing what to do or going on a mission to find x in a location and getting there and not being able to find it.

It's definitely sharper than the CV1 in games like Elite, but the comfort and refresh rate aren't as good. The picture is softer when using Link than when using virtual desktop too.

Also on my Quest I have mura in black scenes which you can't turn off like you can on the CV1 (using the spud registry hack).
 
Sorry for barging in, but just setting up the sidequest for my mother on the quest. Hadn't experienced it truly before, but jesus why does nobody mention the screen door on these things. It's like rolling back 4 years to the Vive. Had a pop on Beat Saber, which wasn't as bad as I thought it might be it played fine, but you can really make out the FOV compared to Index.

On a related note, if your steaming varkanoid, then Xrebirth VR is very good if your looking for a space game.
 
The Quest has pentile OLED screens, so it has more SDE than the Rift S or Index. It is actually pretty high resolution, but rarely runs at the native resolution as it doesn't have the power. It's a lot better than the CV1 though for clarity.

But yeah, going to the Quest from the index you really notice the SDE, lower FOV, and lower refresh rate, but then you can buy a Quest and a Rift S for the same price as an Index and still have over £100 left for games. Or at least you could if they were in stock. :rolleyes:
 
B grade 128gb in stock

I got my 64gb from there with £60 off the advertised price and it looked brand new (had plastic covers on everything inc lenses) - if anyone is worrying about warranty I rang them up about the free Vader Immortal at the time and they said I couldnt have it because the serial number was just before the giveaway but I could register it for full warranty.

Thanks for the replies....

It seems like there should be some kind of clarity index, like some of the VR eye test apps that are available, where a headset is given a clarity value like headset X is 10 and headset Y is 15, but as the image is only x0.5 clearer you won't see any difference.
 
If you're a dedicated simmer then really you need an LCD based headset, due to the subpixel layout, as all the affordable PC headsets with OLED use pentile displays which aren't as sharp. Really that boils down to Rift S, Index or HP Reverb.

Now if an affordable (note: Affordable, the Star VR headset isn't affordable for most people!) PC headset comes out with hi-res OLED displays with RGB Stripe then that might be one to go for.

In my experience, and from what I've read clarity and sharpness goes something like this:

Rift CV1/Vive -> Oculus Quest -> Vive Pro --> Rift S --> Valve Index --> HP Reverb

However clarity on the Quest in PC mode depends on several factors including if you're using Virtual Desktop wirelessly or Link hardwired, and if you've tweaked the various Link settings in the Oculus debug tool to make it sharper.

Also to drive an Index or the Reverb properly you need monster hardware. Sims are the most demanding games, so you often have to drop detail levels or resolution in order to get a playable VR framerate.
 
So.

Installed everything, running the VD app on the PC, Virtual Desktop purchased on the Quest, Sideloaded the VD version so it'll streamVR.

It connects, launches SteamVR.. then problems.

It'll run most of the Oculus stuff I purchased to run through Revive. Stormlands, Chronos, the welcome to VR. Brass, Dreamdeck won't, Asgards is uninstalled.

Nearly all my steam stuff in the Oculus library won't work, aside from Contractors, which is weird. Trying to launch anything from my steam library directly will only show in a desktop window, which is what im having problems with.

I had thought that trying Oculus runtime games like AMS 2 or SPAZ2 in Oculus mode might work, but they won't even launch.

I did notice at one point that they was a switch to VR in the bottom left of the VD app above the already launched SteamVR tab.

The switching to VR screen would seem to be the problem, but I do have my Index plugged in and that's what shows in the Steam VR window on my desktop, it's just odd that Contractors works all fine, Stormlands (even though it runs like a dog), yet nothing else will.

Ravenger, you'd be the man to ask, you run/ran both?
 
Are you running your games from the Games tab in Virtual Desktop settings ? Need to make sure SteamVR runs first when playing Steam games it should auto run. Its probably being confused by the Index but try running the games from inside Virtual Desktop Games menu.
 
Yep using the games tab/library. I'll unplug the Index and see what it does.


Did the trick, it booted the Quest straight in to my SteamVR library. Seemed a little stunted, laggy when playing Beat Saber though, either 2 feet from the router, or over in the other room through two walls.

Is there any magic settings I need to be using in either the VD app on my desktop, or on the Quest side of things.
