Noob to VR. Image/Graphics Quality Question

Hi,

Being a complete noob and a bit thick, I eventually found out that a lot of the blurriness I was referring to is actually called Screen door effect. D'uh! (Old fart =slow learner :). So it seems, to me anyway, that this is just the state of technology at the Quest 2 price point right now. I imagine other, more expensive headsets may have less of this effect.

Sure, my graphics card struggles to give me the graphics quality i'd like but I don't really notice much of the scenery when racing. It is quite acceptable. The cars appear fine. The performance/frame rate is decent enough. No glitches or noticeable frame drops that I can see. Yes I'd like a better card but given the state of the market right now, it doesn't look like I'll be splashing out on a new card soon. (I'm still looking though. Incredible to see there are people on well known auction sites actually paying £650 for a second hand 1080TI. No warranty and unknown history of a card? Not for me, too big a gamble.

As for performance, my RX 590 seems ok. I can even put supersampling up to 2.0 (Although I haven't played it much at 2.0) without any great performance drop.
If that seems odd, given my set up, then I'm probably doing something wrong and my mistakes are cancelling each other out :)

I might add, I got myself a second hand Oculus Go. Using Virtual Desktop I set it up for PCVR. In my opinion, on PCVR I get almost as good an image on the Go as on the Quest 2. Ymmv.

Project cars seems decent on medium settings. Automobilista 2 seems to be way better than PC2 graphics wise on my setup.

I have read somewhere about how the supersampling in-game doesn't work when using steamVR (I think).

The same guy also recommend playing with steamVR and setting your global resolution up to 150% and then dropping it down specifically for PC2 in the "per application" settings.

How is Automoblista 2? Does it implement VR properly?

I've been playing quite a lot of AC mainly in the open wheelers and the graphics look so smooth and sharp part of me thinks it just raised the expectations of PC2 for when I went back to it after oculus solved the usb speeds.

Upping the global resolution and dropping it down? I'll give it a go.
It'd be nice if that offers some increase in picture quality. I won't expect too much of a difference though. RX 590. Can't make a silk purse out of a sows ear.

Automobilista 2 doesn't have a problem implementing VR as far as I can see. It's fine. I have no issues with it.
I'm just a beginner with VR though so don't take my word for it. I could well be overlooking something the more learned among us would notice.
Anyone else play Automobilista 2? Have you any issues with implementing VR?

Quest 2 doesn't really have any screen door effect. That's the black unchanging segment of each pixel.

What refresh rate are you using through the oculus settings? Playing on star wars squadrons i need to set 90hz to eliminate a blurry effect of moving objects.

I'd also suggest turning on the performance overlay to see what exactly effects your performance and what doesn't.
 
@Baldbloke and @jesus2nd Just after reading Jesus's post about supersampling in Steam or in game. For the Quest 2 it's different. If you want to get the best image Quality, I would highly recommend that you turn off the super sampling in game and turn the resolution per eye down to 100% in Steam VR. Then in the Graphic settings of the Oculus App, set your render resolution to as high as you can and still get playable framerates.

This 100%. All these settings are cumulative, and having them all high will cause big performance issues. It's actually not that commonly known, so a lot of people will be having VR performance issues and not realise that it's due to all the different supersampling settings working on top of eachother, and your PC is rendering at a ludicrous resolution.

Launching in oculus VR mode would mean that the steam settings wouldn't be applied though right?

When I had my 1080Ti and my original Rift I was never happy with the performance in PC2 or AMS2. I wanted to increase the supersampling but just didn’t have the GPU power.
I then got the Quest 2 and that was brilliantly clear in headset/native games but IMO looked worse in PC2 & AMS2 because of the compression smeary effect for distance graphics, i.e. what you look at in driving sims.
Only when I got my 3090 and was able to set bitrate to 400/500 in oculus debug tool and in game supersampling to 1.6+ that I was happy with visual quality in AMS2.
As far as I know these ‘tweaks’ help a lot with the smudgy graphics from the USB link video compression.
 
As others have said I get the best results just adjusting the resolution in the oculus app and leaving in game supersampling off and steam at 100%. For sim type stuff I run at about 2400/2500 resolution on a 3090 and adjust in game settings so that I can hold 72 fps as much as possible. For unmodded skyrim I just turn the resolution all the way up and run at 90, it looks pretty good to be honest in terms of clarity on distant objects. I set the bitrate to 500 using a link cable, drop it if you get audio weirdness. For wireless I use virtual desktop on high at 150 bitrate.
 
There's almost no screen door on the Q2. There's a slider in the link section of the Oculus desktop app. On a high end card it can go up to 1.7, on lower end cards it usually goes up to 1.5. 1.7 is native resolution on the Quest 2. Thing is, even a 3080 can't run native. My 2070 Super can get to 1.2 maybe 1.3. The blurriness is partly caused by the Quest being run well below native resolution. The Q2 is one of the highest rez headsets around. It's not that far off the G2 res. Honestly.no card can run either native in a racing sim and I returned my G2 in favor of the Q2.

It can also be cause if the ipd is not set to match your eyes or if the headset is slightly off centre with your eyes, up down left or right. So double check that by moving the headset around whilst looking straight at a bit of text in the centre of your vision.

Next go into a game like PC2, AMS2, or AC. Not ACC. I find AMS2 to be particularly great in VR. Set the graphics to mostly low and medium, run shadows low for instance, but try to get anisotropic filtering at 4 or 8 times and the track texture and medium or ideally high. Do some hot lapping with no other cars on the track. Try to hit 90fps. Make sure in the Oculus app you are at 90hz and 1.2. In the debug tool you can turn on an FPS overlay.

You should be able, at least hot lapping, to get a decently crisp image. There will be some shimmering and aliasing because of the up scaling. We need a 3080, to really improve things, but to get native it's probably a year or two away.
 
Great tips here, zero71. Thank you for that.
I actually sold my Quest 2 last week and got a Rift S just to see if there was much difference. There's not. But then again my RX 590 must be the limiting factor.
I've got a used 3060 GPU arriving in the next couple of weeks. I hope to see some improvement. Probably modest ones though.
I'll try those tips when I get it.

I may get myself another Quest 2 in the future. I'm now suspecting my less than great impression of the Quest 2 was down to a very low end VR gpu and my lack of understanding of the settings. There are so many possible options (and pitfalls) it can get a bit bewildering.

And I agree about AMS2. It does seem to be a better image quality than most, without tweaking. That and PC2.

Now, if only I could find time to play the games instead of tinkering with the settings.
