Optimizing Quest 2
-
Has anyone managed to set up their Quest 2 to optimize graphics? After much searching ( and with kind help from this forum ) I have finally got smooth results running an Nvidia 3070 and 13 Gen i7 with Virtual Desktop and a wifi6 router, but still find the graphics quite blurry. And I’m getting confused between Oculus, Steam VR and Virtual desktop settings.
-
@danster Why don’t you use the cable and Oculus link? As for the blurrines I had to move the resolution slider in Oculus link all the way to the right. Otherwise the picture was unacceptable. I also set the resolution in Steam VR on 100% and 1.1 factor in BMS config file.
-
@DanWolo As I said, Virtual Desktop is giving me a smooth wireless result. Do you think a cable link ( which I have if necessary) will improve the blurriness issue? Will certainly try changing the Oculus resolution slider, but wondering what settings take precedence, Oculus or Virtual Desktop (or Nvidia or Steam)? I’m a total idiot at VR.
-
@danster all resolution sliders will be multiple of each other.
-
@danster Try to increase the Quest resolution first keeping the rest at 1.0 or 100%. Then you can move another sliders if the picture is still blurry but I bet you kill the performance with just the Quest slider. If you have both the cable and wifi 6 you can also do the back to back comparison and check in which case you have more frames.
-
@DanWolo I run a 3070 and have everything at 1.0 except quest 2 render slider, which is maxed. This will give the best possible 1:1 clarity with no supersampling.
-
@obsidianuk Do you have stable 72 fps with this setup?
-
@DanWolo no, normally run 80hz, but with AWS forced on, so stable 40
-
@obsidianuk No ghosting in dogfights or when passing by another jet at high speed?

I know you’re using VD.
But for wired Link, some key settings are the encode resolution and bitrate. As with all things oculus, the defaults are very conservative. Bitrate of 300 and encode resolution in the mid 3000s should be a good starting point to reduce compression artefacts.
After that, resolution is key to balancing performance and quality. You have many places to play with it - oculus itself, steam Vr and then BMS render resolution. Oculus and steam Vr can cancel each other out (eg if you set oculus high and steam Vr low) I think - I no longer have a quest and never used steam Vr with it so I could be talking rubbish.

@DanWolo probably, but I usually avoid WVR combat.

@obsidianuk A possibly stupid question:
If I measure my latency, using the Virtual Desktop tools, its quite high- in the 40s- yet I don’t get any stuttering or other issues besides blurriness. I gather latency should ideally be in the 20s or below. Will adjusting settings to reduce latency improve the blurriness? Maybe I don’t understand what latency is; I assume it means the picture stutters.
I’m running the max refresh rate of 120.
-
@danster From what I gather latency will be the delay between when the image rendered to it being displayed in headset. I don’t use airlink or VD, but believe a latency of 40ms is typical for non wired. I think to get 20 you may need cable.
But if the picture is smooth then don’t worry about the numbers!
-
@obsidianuk I agree. One can get fixated on numbers e.g. Some people are obsessed with frame rates even when the picture is stutter free. That being said, I’m uncomfortable with the “blurriness” I’m experiencing and will play with the “Resolution per Eye” function.

Latency in this regard would refer to the time it takes for the image to be drawn to the screen following a change in that image (such as moving your head). The lower this number is, the tighter movement to response ratio will be. The way our eyes and mind process this information varies between individuals to a degree, but in general, a latency less than 20 (preferably less than 14) is optimal. This is not universal, and some users may require even lower latency to avoid motion sickness.
It’s worth noting that there are different types of latency in VR, including motion-to-photon latency (the delay between a user’s movement and the display of that movement in the VR headset) and display persistence (the time it takes for pixels on the display to change). Both types of latency can contribute to the overall latency in VR, and reducing both can lead to a more immersive experience.
EDIT:
On Nvidia GFX cards, there are a couple settings users can change to enforce the lowest possible latency. Set the following settings as shown below.

@SemlerPDX As ObsidianUK correctly said , one should not fixate on numbers. Although my latency according to Virtual Desktop, is in the 40s, I’m not aware of it i.e. I get no stuttering or strange effects-using Virtual Desktop wireless.
My issue remains the blurriness I’m experiencing which, as far as I understand, is all about resolution. So I still wonder if that’s just BMS or is it my set up.
Nevertheless, having experienced BMS in VR, I’m hooked.
