Quest pro set up for 3090

I didn't explain my self well, not at least to the end, this is what I use for the undervoltage:

You had gone that low, to 750mV? Really? Or it has been more like 1,750mV?

Yes, I checked my notes for the 3080Ti - your curve won't do anything for you it seems, looks like the default curve to me. Values above 900 mV don't matter because the GPU will never hit that mark. You can have the curve diagram opened while gaming and you can observe the current voltage output in real-time.

My 3090 curve on my second PC looks like this right now:

That is 1770 Mhz with 825 mV with the RTX 3090.

 

My prefered values for the 3080 Ti have been:

750mV / 1665 Mhz - (~280 W / 75° max)

775mV / 1695 Mhz - (~290 W / 76° max)

For maximum performance this has been:

825mV / 1845 Mhz - (~330 W / 85°+) -> even with these maximum settings the card used 25 W less than 355 W on default clocks.

Give it a shot - I think you have alot of undervolting potential ahead with your card.

Thank you, will try these settings tomorrow. And sorry, I previously mistakenly swapped Frequency with Voltage

What about the ether settings, I have them like this:

I used your 2nd option, and it seems fine, stable and just 5-10 fps less then when card used 300+ Watts

Look at the usage and temps, wow

With gpu power consumption of over 300W, temps are 10degC + and only 5-10fps gain. And fans are spinning way faster (they are also louder of course). This setup seems pretty reasonable. Have to try it in VR now.

I have MSI afterburner installed, can some one show where / how I access those adjustable settings, would like to try Tepnox's ones for the 3090.....on my GUI for the app, the core voltage, power limit etc are shown as percentage sliders, not values......

There is a pretty nice tutorial on Youtube for 3080 / 3090:

Try choosing another skin inside MSI Afterburner settings (Tab User Interface), using that right now:

[skywalker22]

In VR and Quest PRO: constantly 40fps (data by openXR Toolkit). Funny thing is, that I have a completely stutter-free picture (specially on a side view, left/right, turned into the ground) even on 40fps. And without motion reprojection turned on, maybe vr headset does that instead. Really smooth picture.

VR data of GPU with your settings:

[markturner1960]

So I am curious how you have constant 40 fps if motion reprojection ( ASW) is turned off? 

[TZeer]

Force 45 FPS, ASW off, run 80 Hz refresh.

80 Hz from the setting page in the occulus software. The rest from ODT.

OK, thanks - what would the advantage of that be, given that the ASW works so well on this headset?

I don’t see any point in locking to a low frame rate and not using ASW, especially if your PC is beefy enough to push the QP. Or reducing from 90fps. 

[markturner1960]

OK, thanks all.....its been an enlightening few days and everyone here has been so helpful. As the information is scattered across multiple threads and posts, I thought I would summarise here for others what works for me: ( i will caveat that by saying I dont have a deep understanding of how it all works, and there are others here who do, so ...) 

In Oculus home: Set resolution to 1 ( 3936 x 1984) This for me gave the best combination of frame rates and graphics quality, along with the other settings below

In OTT I have supersampling at 1.4, ASW on auto, in the quest link section encode resolution 3905, bitrate 0 dynamic bitrate & sharpening enabled, max dynamic 750

In ODT, I have FOV tangent multiplier at 0.8; 0.8  All other settings as default.

In DCS, PD is 1, MSAA x2, Shadows medium, clouds high, textures high, vis range high, Anisotropic x16, terrain shadows off, No lense effects or heat blur,

I set my GPU to 1770 mhz & 825 amps in MSI afterburner as above. In OpenXR perf tools, I have foveated rendering on set quality wide and the post processing for the sunglasses feature. Everything else off

The net result of all this in DCS in the F16 free flight mission & Banklers carrier case 1 trainer mission ( which can be demanding) I can manage 80 FPS most of the time with dips into ASW maybe 30% of the time? Have to say, if I did not have the FPS overlay from openXR performance tools, then I would not even notice the ASW was on and frames were lower, its that smooth.

This is an amazing headset and my DCS experience is just fantastic now....I usually fly  a mix of 2D and VR, and I have a really nice 2D monitor, but really, I am thinking I wont go back to 2D now, the headset is so light and comfortable and the image quality so good....Very happy! 

 

Thanks again to all who got me here!

I have approximately the same settings.

Do you also have set the Display Resolution (per eye) in OpenXR Toolink:

I have it set to 2200 x 2300 (or sometihng). But I have this still from my previos Reverb G2 headset.

[markturner1960]

No, I have turned that off, so as Nikoel says in another post, the resoltion is only set once, in one place. For me, thats the Oculus home and I have it at 1. Then use supersampling in OTT (1.4 for me)
