VR Discussions, Questions & Feedback

To the best of my knowledge frame generation features like dlss3 and fsr3 do not work in VR but only in desktop mode

frame generation in VR is ASW for oculus or smoothing in steamvr

 

Would love to have Dynamic Foveated Rendering as the posters above suggested!

 

DLSS in non-VR can greatly improve performance, but in VR DLSS looks AWFUL, you are much better off reducing the resolution scaling within your VR headset settings, or in the case of Quest 3 just using "potato" quality.

 

Since I use AMD, I never used dlss, but since I consider fsr (even 1.0) use essential for vr, I can hardly understand dlss would be worse.

Fsr significantly improves sharpness of the screen for reverb G2 using it in open composite with XR tools.

 

Okay, then I'm okay to have DFR as it would give headroom to increase the scale as well.

 

well it took sometime, there where some troubles with the store and delivery and the parcel service. But finally,tomorrow it will be delivered. (Quest 3). Link cable will be here next Sunday. Headstrap BoboVR s3 is currently out of stock. So I have to use the standard which comes with the Quest 3.
I presume I can use VD from meta store as well? it is the same application. I noticed that I purchased it at the time I just had my Rift CV1. Already 8 years ago.
Anyway, I hope I can get the whole setup working with a reasonable FPS. (Steady 90 would be nice)

 

Am i the only one seeing water spray clipping into the cockpit on this latest update? Is it just a VR thing? Ive got a Quest 3

 

@Shodan0000
So, you are using FSR instead of CAS to sharpen the image (corner signs etc.)?
Can you please post your FSR settings and resolution pls?

I run a 4080 and have to use a resolution of ca. 2900x2900 or so with CAS in order to achieve 90FPS with more or less medium settings in AMS2.

 

FSR and CAS are two different things FSR is an upscaling solution, so you set a percentage of the orignally requested resolution and FSR upscales that. This gives the benefit of reducing load on the gpu. There is a sharpening pass applied after this upscaling. But FSR will reduce image quality as will NIS

CAS is contrast adaptive sharpening and it is just a sharpening pass, if you don't need the performance benefits of FSR, just use this instead to sharpen your image or you can sharpen it through dx11 config file in your AMS 2 Documents folder.

 

This is wrong.

FSR is used to get a sharper image. I see this misconception many times.

It does not work like this in VR.

For VR you have the following hard requirement in mind: 90fps in all scenarios. That is a given.

Any tricks you do to the image are there ONLY to get the best picture quality at this 90fps. It makes no sense to do something to lessen the load, guaranteed 90fps should be the outcome anyway.

Using fsr you can achieve a sharper image at 90fps then without, with the cost of some artifacting. If you really don't like this artifacts, then of course you should not use it, but personally the much sharper image possible at 90fps far outweighs these occasional graphic glitches you can see for me personally.

My settings are 75% fsr ratio and I believe 35% sharpening. For reverb G2 (3000*3000 native per eye)

 

so you are saying that (3000 * 3000) * 75% upscaled to native produces a better image than 3000 * 3000 native? Because that literally makes no sense and FSR is there as a performance tool.

 

Of course that is not what I am saying, and again, this is where the misunderstanding comes from.
I have a 6900XT, and obviously that is never ever going to get stable 90fps at 3000x3000. If I want to achieve 90fps (keeping in game settings the same). I would probably need something around 2500x 2500 resolution.

So you have to compare 2500*2500 image quality vs upscaled to 3000*3000 quality with FSR And in both cases having the same buffer for GPU usage to keep stable 90fps. The latter is significanlty more pleasing for the eye, at least on HP Reverb G2.

In that sense, no fsr is not a performance tool, (well I guess it depends on how you define it of course) but an image quality tool for a much sharper image.

 

What misunderstanding? Nothing that I wrote in my post is misunderstood, you yourself are literally using it for it's given purpose of upscaling a lower resolution image so that you can achieve higher fps at the expense of a lower quality image than native, this is the definition of a performance tool.

If a user does not need the performance overhead provided by FSR they should not be using it. If they just want to sharpen the image they can use CAS or edit the openvrdx11 config with a low sharpening strength of something like 0.2 - 0.4

 

The bold part highlights that you still misunderstand what I said in my posts:

- You are not achieving higher fps! That was the main point of my first post. framerate is a given 90 fps. This does not change, you will always target 90 fps, no less, no more.

- There is no point in comparing things to "native" resolution. You need to compare the image quality that you can achieve at 90 fps with and without FSR.

Effectively FSR improves image quality for VR, since 90 fps is the target. That is what you should use fsr for, not for performance (meaning more fps)

 

I like both your arguments, and I think I finally understood the purpose of an upscaler or CAS in VR.

I run at the moment 90fps with a resolution of 2900x and CAS. I will compare the visuals (sharpness) to it with a higher resolution and FSR. FYI I change resolution of AMS2 only via resolution override in the openXR toolkit and do not touch it anywhere else.

 

Help, I have a weird problem, should steamvr start when using PimaxXR?
It's doing so at the moment, and I cant change it (tried changing to Steam, and back, reinstalling PimaxXr)
I have not set SteamVR as the openXR runtime.
The main problem now is that I cannot start the OpenXR toolkit.....

 

For FSR the approach should be to look at your current settings that you trust give you guaranteed 90fps with some headroom. Take a track and look at the headroom number using OpenXR tools.

Then you apply FSR and increase the resolution until you have the same amount of headroom. Personally I use 75% FSR and 35% sharpening I believe, You can ofcourse change these settings as well, but they should be constant when you are tuning towards the headroom you also have without using FSR.

I hope this makes sense.

 

Well got my quest 3 hooked up and it looks awesome.
One question, how do I set a “select” button on the gaze control in the VR settings panel of AMS2

 

Gaze control activates when you stare at a button without moving. I don't think you can set a key for it. I've had issues with gaze locking the mouse cursor in the corner of the monitor, so I've turned it off. I prefer using a mouse.
