Oculus Quest 2 clarity **solved** with 200 render scale hack

[BaseKamper]

Hi fellow Questers,

Ever since the 200 render scale hack was released I was very frustrated - it completely solved performance issues, but my clarity remained very poor. I spent many nights trying to figure out how some users have solved all their issues and I’m still doing bush trips through a screen door.

And finally last night - my ‘A-HA’ moment. It is the OTT stupid!

Apparently, it is a bug, or some stupid mistake on my side, but whenever I launch the sim my Oculus goes to SuperSampling = 0 (which is also 1.0). That means I didn’t enjoy from the extra pixels I was sending the Ocolus from my Nvidia.

So here is a short description of my problem, and how could you identify if this is also your problem.

I hope I can help at least one more user, and make Ocolus VR a better place

My specs:

CPU: i7-10700kf
GPU: RTX 3080
RAM: ​32GB
Nvidia driver: 471.11

Ocolus Quest 2
Ocolus version: latest 30
Ocolus resolution - 90Hz 4480x2256
Oculus air link over 802.11ax

Do you have this issue?

1. Start Ocolus Tray Tool aka OTT
2. Start the sim
3. Do the 200 PC Render Scale hack - out of the scope of this post - Google it
4. Start your flight. I suggest you use the Cub Savage so we can all be on the same page
5. In the Cub look at words “AIRSPEED” and “ALT” - if you suffer from a screen door effect you will see them blur.
6. In OTT choose from the HUD the “Pixel Density”
7. Now in the OTT window inside the sim you would see that the bottom line says “Pixel Density 1.0,1.0” - BINGO!!! This is you screen door effect

How to solve it?

Most basic solution - increase the supersampling in OTT to the one suited for your machine.

You see, when you increase the SS you severely increase the load on the Ocolus.

I choose SS 1.5 with a VR Render Scale of 90 and FOV of 0.80. The rest of the settings are pretty much my sweet spot, but if required I’d post them here - NP.

How to verify issue solved?

1. Go out of VR mode
2. Change the OTT as described above
3. Go back to VR mode to make the Ocolus accept the new configuration.
4. The “Pixel Density” should now show the new SS
5. You can replace now the HUD to “performance” and find you fps sweet spot - I know I did :)))
6. Go back to OTT, remove the HUD and fly away

A few more tips:

1. Remember that on each start up the ASW is set to auto. Set it back to Off with Ctrl+1 (or in OTT go to auto and then back to off)

2. When you go from Ocolus home to the air link, you see this new environment that comes from your PC - I’m sorry, I dont know its name:

3. Choose the leftmost button in the gray panel in front of you. The label will say “air link”.

4. Choose “Dynamic” and I set the max mbps to the maximum 200. Keep the changes

5. In OTT to the Quest Link tab and choose 0. As you can see above, 200 is the maximum anyway. If you manually choose above 200 you will see the Ocolus go wild with black rectangles and slideshow - mine does.

That’s it. I hope I helped someone out there.

This is the time to thank this wonderful and inspiring forum, and especially the YouTubers “PIE IN THE SKY TOURS”, “The VR Flight Sim Guy” and “theVRpilot”

Please let me know if you require any more details for reference. I didn’t want to clutter this post with long shopping lists.

i tried and i think i got something pretty good, i need to do it again to be sure…
i set 1.3 SS in OTT to be able to sustain 16 FPS, the result was quite good.
my conf RTX3070, Ryzen 2600X, 32 Gb RAM, Quest 2, all last versions
but quite everything was ULTRA in MSFS VR tabs, and 200% in PC.

@BaseKamper Thanks for the mention and your support - this is interesting so will check it out too.
Cheers!

In OTT to the Quest Link tab and choose 0. As you can see above, 200 is the maximum anyway. If you manually choose above 200 you will see the Ocolus go wild with black rectangles and slideshow - mine does.

Could you please elaborate? Why should you set the bitrate to 0? Wouldn’t this contradict the setting you’ve chosen in Oculus Home?

[BaseKamper]

Good question.
Proper disclosure, I’m answering by reverse engineering the system. Nothing that I say is the ultimate truth.
The setting in OTT seems to complement in some sense the value in Ocolus Home.
My guess is that the value in Ocolus is the maximum number and you should give it the highest value. So this is the upper boundary. This is also a value I trust to work since it is in a native Ocolus software, and well explained in the software.
The 0 value in OTT I guess take you the default or best effort value. My estimation is that if you leave at 0, this will eventually take you to the maximum value defined in Ocolus Home value.
Anyway, I do now that if you go beyond 200 it starts glitching, so this boundary got me to the conclusion both values are linked, and these values will give you the best Air Link bandwidth.

Again, this is just an estimation and I’d love to hear more opinion, or even better an actual explanation on these values interact.

Quick question, I’m trying to source a GPU for VR. Is RTX 3060 any good for it? Or do I need something beefier?

[BaseKamper]

My advice, wait till the YouTubers I mentioned above will review performance of Sim Update 5 releasing on 27th July. This update might change dramatically all current benchmarks.
I have 3080 and it look like it struggling for a clear view and 3090 is the only decent GPU.
I believe it will change. Just hang in there for two more weeks

[HPRacer5605]

Thanks for the advice. Sure, will wait and see how it unfolds. Think have to even wait for another 3 months hopefully production of GPUs picks up by Thanksgiving. Already see some big players promising delivery of 3080 Ti based systems in August.
