Quest 2 Airlink-- Oculus Debug Tool - ASW auto / disabled?

[dopamineoverload]

I can't seem to figure out what the best option is... I'm getting FPS drops when there's 3 enemies on screen at the same time... ASW is on Auto. I set to Disabled, and it seems to respond exactly the same way. I don't know if there's an advantage to it. I've found that with Virtual Desktop, DISABLING SSW (VD's answer to the official ASW) makes games respond a million times better/smoother.

GPU: 1660 Super
PC: i7 4790, 3.6ghz, 32GB ram, SSD system and 2nd internal

I'm closer to getting more solid gameplay... but it's not quite there.

Recording the gameplay with OBS shows the game responding smoothly with no lag. But inside the headset I'm getting dropped framerates.... have the Performance overlay... I have the headset on 120hz, with bitrate 120. Normally, I'm 90/90 with Virtual Desktop. Airlink seems to be responding better, but overall, I'm getting around 60fps, even with ASW off... which leads me to believe... is it really off?

Any help is appreciated. Thanks!

Hey! For ASW, it is only to lock the frame rate to half if you prefer it over a fluctuating frame rate. So the frames would be more smooth and stable, albeit at half rate. Some people hate this and some don't care, so it's up to you.

However, some things jumped out at me -- you mentioned running the game at 120 in the headset. I would wholly recommend you lower that to 90, as the game really can't handle 120 too well. You should see a massive improvement if you drop it to 90.

And then something else to just be vigilant of; running OBS itself will impact your performance as both things are hogging your CPU. All the physics mean the game is CPU centric, and OBS is CPU hog too. I used to stream and this was a pain for me.

And last, Airlink can be hit or miss (the Quest is currently not officially supported). Some folks are playing Airlink and having no issues. Personally I cannot get Airlink to run any VR game smoothly! It tends to be the case that people who can't use Airlink have better luck with a tethered Link cable, though funny enough I have heard the reverse too!

So you kind of have the unholy trinity of performance red flags going at the same time right now haha, 120, OBS and Airlink. Have a look into those first.

Then, if you are still struggling, here are some options to change in the settings that will greatly help:

Set "Physics Quality" to low
Persistent Bodies and Items to 1 or 2
MSAA to off
Render Scale to 0.75 (only do this if you are still struggling with performance)

Have fun!

THANKS, Baron. Someone on Reddit said 120hz for him was "buttery smooth" the whole time... but I have not found this to be true, by and large, haha.

What I think I might do (re: OBS), is record gameplay to a separate system. Apparently running DisplayPort to HDMI... then to an HDMI-to-USB capture card.... that takes the load off the gaming system. Could you verify? I've seen a lot of people do this. I have a 32GB ram laptop, quad-core i7 (2nd gen), with a 2GB Nvidia Quadro 1000m in it... 2.7ghz. For just capturing HDMI at 60 shouldn't be too much for it. I've done this before I got a gaming system, capturing Quest gameplay directly... worked pretty well.

As for Airlink-- ODD! Yeah, usually it works awesome for me. In the case of B&S, considerably better. VD hates my Blade & Sorcery, but.... then again... I was trying both at 120hz.

And lastly-- yes, those tweaks. I found those first, as soon as I started playing Blade & Sorcery and running into issues! :)

Buttery smooth 120hz... Maybe! You never know, but definitely not my experience haha. Your OBS plan is a great one; if you can do that setup if will work really nicely.

I've delved into the Oculus Debug Tool for the Quest, exploring its various settings and functionalities. This tool offers numerous options to enhance your VR experience, and I've consolidated the key points to help you navigate it with ease.
-Some of my insights:
*Accessing the Tool: The Oculus Debug Tool is part of the Oculus PC software. It's found in the "C:\Program Files\Oculus\Support\oculus-diagnostics" directory by default.
-Important Settings:
*Link Sharpening: Enhances image clarity without performance penalties.
*Distortion Curvature: Adjusts pixel density between the center and periphery of your view.
*Encode Resolution Width: Alters pixel count in the output image.
*Encode Bitrate (Mbps): Influences video stream quality.
*Encode Dynamic Bitrate: Dynamically adjusts bitrate based on network quality.
*Pixels Per Display Pixel Override: For supersampling or downscaling the image.
*FOV-Tangent Multiplier: Modifies the field of view to potentially improve performance.
*Asynchronous Spacewarp: A frame-rate smoothing technique.
*Mobile ASW: Optimizes frame rates for Air Link sessions.
*Adaptive GPU Performance Scale: Controls dynamic resolution scaling.
*Use FOV Stencil: Related to GPU pixel processing.
*Frame Drop Indicator: Displays on-screen frame drop alerts.
*Bypass Proximity Sensor Check: Previously allowed display to remain on when the headset was removed, but may not work with Quest 2.
*Force Mipmap Generation on All Layers / Offset Bias: Deals with texture resolution at varying distances.
-Troubleshooting Tips: Restarting the Oculus service can resolve issues with settings not applying.
-Performance Overlay: A useful feature for measuring and optimizing in-game performance.
-Resetting Default Values: Manually reset numerical values and dropdown options to default to undo changes.
-Useful Menu Items: Includes Performance Profiler and Mirror View for gameplay monitoring and sharing.
