Virtual Desktop test Quest 2 IL-2

[kuk111]

below is a little gameplay recorded by the Quest 2 itself, using Virtual Desktop.   gives a decent job of showing clarity and gameplay using VD on quest 2. I also never saw ghosting (double planes) as they would pass my aircraft.

New Raw recordings below from Quest 2.  Used ADB command to match recording resolution to native resolution of Quest 2 1832 x 1920 per eye. Quest records left eye. Recording bitrate still a factor but you can see how clear instruments and aircraft are even with that factored in.

also just as a proof that the in Quest recording would show if anything looked like a blurry mess below is a capture with SteamVR resolution set to 30%

Seems smooth and nice, even with shadows enablend, seems quite improvement over Rift S!

How about pixel density?

With Rift S what bothers me the most is i can count pixels and flickering

[kuk111]

There is no distracting screen door at all. If you really focus hard on a uniform spot, you could maybe see the tiniest amount.  But you really have to go hunting to find it

I am just waiting on my elite strap with battery to fully replace my Rift S.

Pixel density is a bit over 800 (without knowing the exact size of the panel). I think the Rift-S is 600.

i just connected Quest2 + VD and somehow i have very strange perspective aberattions... like i'm having incorrect FOV. especially when looking down the cockpit...

I’ll test mine again in a bit. Are you launching IL-2 from the games tab in the VD menu?

[kelemenlajos]

I haven't dialed in my settings yet, but here are my test results (App Tracking to Mid-Photon via OculusTrayTool):

 

CV1 : solid 27ms sometimes spikes that stays below 39ms (using 90Hz mode this seems to be 2-3 frames + the overhead)

Quest 2 with Link cable: 44-46ms depending on the surroundings, somtimes spikes with 50-51ms if new complex visuals are shown for the first time for example cities (this is on 72Hz mode this also seems to be 2-3 frames + overhead)

Quest 2 with VD: Sadly there is no working measure method for this (VD is not reporting App Tracking to Mid-Photon), but i get the same feeling that with Link Cable, but i got some lag spikes- but i think this is because i have some issues with my pci-e wifi card (Tp-link AX3000).

 

Is there a way to compare these results (measuring game frame render time, frame sending and receiving, frame showing time?) with one app, that can be recorded with the video? Also i was live streaming to FB for archiving my results, and maybe this broke the VD test, and the VD test are in 480p all the others are in 720p in FB. I would like to finetune my settings, to my config (i7-8700, 1080Ti,16Gb ram), and not use a copy paste values from old threads.

 

 

 

 

[KookyBlimp]

nope, from steamvr

Can the Quest 2 run BoS with open Composite?

[kelemenlajos]

Yes, but i managed to start it only without sound.

(create an opencomposite.ini file in the same dir as openvr_api.dll and put this into the ini:
enableAudio=False

)

 

Sadly with this you will loose the positional audio. But if you got a decent pc i don't think you can get too much latency out of it.

With link, and steamvr i got 47ms in average with link and opencomposit 45ms. I don't think it's worth it.

I’ve noticed the same thing. It’s like a fisheye effect which is especially noticeable when you tilt your head.  Tried everything to sort it but no joy. I can run Elite and Alyx from VD and DCS from the VD streamer app with no issues. 
 

I haven’t been happy with Oculus Link performance on my system as anything over high preset with most options turned down and SS on 1.0 and I’m struggling to maintain 72hz. This is using the official Link cable. 
 

Even with the fisheye effect, on VD I was able to maintain 90hz with SS on 1.5!! Just made me want to puke after two minutes.

Hey I'm having the same warping issue running IL-2 on a Quest 2 with VD, but strangely it runs fine on Oculus Link. VD is just so much easier, smoother, and prettier than Link though, and I actually think Oculus cuts back the FOV from 104 to 95 or so, probably to save on the bitrate. I had the original Quest running VD before and didn't have that issue back then. Tilting your head skews the image, and looking up and down somewhat shifts everything. Nauseating for sure. Tried a bunch of stuff as well with no luck. And IL-2 is the only game doing that, other SteamVR and Oculus games are all fine I'm actually wondering if it just started with the latest build of VD, I hadn't noticed this 1-2 weeks ago. Running on the following: 10600K, RTX 2060, 16GB Ram. Will continue trying stuff and advise if successful, keep me posted as well if you find anything.

I would think asking a headset to run IL-2 wirelessly with smooth performance might be asking a bit much of it.

[mathdesj]

Actually, Virtual Desktop does a surprisingly good job at it, much smoother really than the official wired Oculus Link option. You just need a decent 5GHz wifi setup, I basically have a separate router dedicated to the Quest only and it works great. I'd say just getting IL-2 to run in VR with decent framerates is a bigger challenge than the wireless portion of it. Just turning on the HUD is probably more taxing on the system than encoding the wireless stream. 

 

Either way, this is off-topic, the issue here isn't the wireless portion running smooth or not, it's that the perspective is skewed or warped somehow, as if in wrong aspect ratio or wrong vertical scaling. For some reason it's only an issue with Virtual Desktop, with Quest 2, in IL-2. And for some reason it only started happening in the last 1-2 weeks. I'm at least glad I'm not alone with this issue.

Oh yea, nevermind about my "off-topic" comment, forgot the OP wasn't necessarily about that specific perspective issue. IL-2 is one of the main reasons I upgraded from a Quest 1 to a Quest 2, with it's better clarity and all, so the game not working right is driving me nuts :-)

Virtual desktop is pretty amazing really. Using FPSVR my GPU frame times are lower under virtual desktop than using Link and weirdly the picture looks better. Could be down to VD running at 90hz compared to 72hz on Link but also could a resolution thing- though surely pushing 90 FPS would tax the GPU harder!!! I’m running VD on medium and Link on automatic with no supersampling - Il2 on high preset with most options except clouds on lower settings and MSAA x 2. VD wireless performance is pretty faultless since I set up an old 5ghz ISP router as a dedicated quest access point - the odd little hiccup but generally great and for games like Alyx playing without wires can’t be underestimated - not such an issue for sim use.

ok so I’ve now got it working - sadly I’m not exactly sure how. I have VD set to medium streaming quality, with sliced encoding. 90hz is activated using side quest and the beta feature menu in the headset - this needs to be activated again in the sidequest each time the headset is powered off - standby seems fine. 
Supersampling is off in steam and oculus and oculus graphics are set to auto (though I don’t think this will effect anything as VD sidesteps the oculus app. 
I was also playing around with opencomposite at the same time - which I couldn’t get to work with VD but possibly the changing the dll may have helped. 
Whilst tweaking settings it did go all skewed again and unfortunately whilst it did come back eventually I still didn’t identify the cause and it could possibly be random. Like you only IL2 seems effected. 
I’ve been on the VD discord and apparently the developer is aware of a random fish eye fov issue which is being looked at!!
 

What I’m confused about is why IL2 performs better using VD than Link. Hopefully when the Link beta ends things will improve. Does anyone have both a quest and something like an index/g1 to be able to directly compare performance?

Ok thanks for the tips on solving the fisheye. I've tried matching your settings and screwing around with the DLL's and OpenComposite but haven't been succesfull so far. I haven't been able to launch opencomposite thru VD either, but was mainly just trying to replicate whatever you had done. I've posted the issue on the VD Discord but haven't had a response. Hopefully this will get patched either thru IL-2 or VD at some point. 

 

Agreed on playing Alyx wirelessly, I can't imagine playing it while tethered. I can't comment on the Oculus Link performance, ever since I've managed to get VD to run smoothly, I'm disappointed by Link every time I try it again. It always seems like a 2min stuttery mess to get it launched, but performance seems to vary from user to user. 

[Skood]

if you are signed up to the oculus beta channel then they have released a big update to oculus link today allowing the selection of 90hz and encoding resolution within device settings of the oculus app. Early testing looks good - noticeable improvement in performance so far but need to experiment more.

Hey guys, have you managed to fix the skewing when playing il2 via virtual desktop? It's unfortunately unusuable for me that way.

[mathdesj]

Still no luck on my end. I've noticed this same issue popping up elsewhere in the forum, steam, and reddit, so at least we're not alone. Still works ok with link though, and link for me is now a lot smoother since it came out of beta. 

[mathdesj]

This issue seems to have been resolved from my end at least in the last month. IL2 now works fine with Quest 2 and Virtual Desktop. Yay!

Is Virtual Desktop functioning as a better version of Oculus Airlink? I'm confused as to what Il-2 presents like in the headset using VD. Is it still VR but with better performance? 

[mathdesj]

Virtual Desktop is basically the same function as Airlink, so it still displays in VR. IME, it has an easier interface, better performance, and better visuals than Airlink. Your experience with either VD or Airlink may vary depending on your setup though, so suggest to try both options and stick to whatever you prefer. Like Airlink, it'll depend heavily on your wifi setup, but I find VD is even smoother than wired Link.
