RTX 4090 vs RTX 3090 - Comparing DLSS, TAA, all options maxed out, OpenXR @ 200 (5900x, G2)

DLSS Performance

Thank you :slight_smile:

Thanks for the suggestion to go 200 in OpenXR and DLSS Performance. It was the icing on the cake after messing for two days trying to optimize my new build. I can confirm that the performance of the 4090 (Gamer X Trio by MSI) on a Ryzen 7900x, 64GB 5200 DDR5 is a pretty big boost in performance all around, running ULTRA in VR at last. I have also noticed that moving in and out of VR is much more responsive and trouble free with the new system. I have the Buttkicker Plus and Next Level V3 motion platform layered in as well. All working together nicely. I came from a Ryzen 7 and 3080.

Does this mean motion reprojection and ASW are a thing of the past now then? I have 13900k, 4090 build being constructed for me now by PCSpecialist. Hoping it gets to me before Christmas so I can use it during my two weeks off!

Well you can still use Motion RP if you want - it will almost always be locked at 45, and you’ll get 90 FPS.

Of course… you have to try :slight_smile:

Are you using OpenXR Toolkit? If so what are you Foveated rendering settings?

I am guessing you are running Reprojection in in Open XR as well correct?

No I don’t use the toolkit anymore. I found that - on my system, at least - it slightly worsen the performance.

Thanks, I will try without the toolkit and see if it improves.

I also get better performance without OXR toolkit.
But then I cant use Shaking reduction and without it, its unusable for me on G2.

I can confirm in connection with the 4090. You get it set up in such a way that there are no losses, but it makes no difference whether or not it is loaded. With activated FFR, it tends to ensure that the GPU is not properly challenged. So counterproductive.

I have seen the opposite on my 4090. I only use the OpenXR Toolkit for the FFR with the varjo aero, nothing else (no scaling or other things like color changes, etc). The GPU runs at 100% all the time, so I don’t see any less usage of the GPU in VR by using the OpenXR Toolkit and it doesn’t impact my FPS, but each system is different and of course the other myriad of settings folks use. I am using the default High preset on MSFS for graphics, and the aero headset at maximum resolution. i9 13900k, 4090, 64gb ram.

Dumb question maybe:

People are saying OXR at 200, where is this setting?

Flying VR, 13900KF, 4090, Quest 2, Virtual Desktop

It’s a setting related to WMR (the OpenXR tools add-on software actually that allows for further edits of the base WMR program) for the reverb g2 headsets only, and refers to the resolution scaler so 200%.

There has been some placebo affect going around with respect to this setting:


Custom render scale should be at 100%. I fell for it myself because I decided to test two changes at once. VR is working great now in the G2 with DX12. With your 4090 set WMR to Best Visual Quality. Disable Motion Reprojection. DLSS Performance is butter smooth. You should try DLSS DLAA. I can just do DLAA with my 3080ti, but I do see some motion artifacts. With DLSS Performance it’s perfect. I have turned off all OpenXR Toolkit features.

Steam has something similar, right now I have it set at 150%. Maybe I will play with it.

Check out this thread:

Placebo effect? Are you saying OXR100 looks the same as 200?

No, but it does not bring sudden performance improvement.

Sorry, i dont get what you are saying. Reducing OXR from 200 to 100 doesn’t improve performance, but some people think it does, so thats the placebo you speak of?

200% OXR provides higher clarity reducing shimmering at the severe cost of fps. I’ve found this in both DLSS and TAA. I’ve chosen clarity over fps. I’m using an rtx3090, so it’s a sacrifice in terms of fps, but those with the rtx4090 is should imagine it’s as smooth as silk.
