Anti aliasing and shadows ugly in VR

[m0rta_della]

I think this game has so much potential but the image quality in VR is so distracting to me, I wonder if shadows and anti aliasing are broken on my machine or if it's really that bad and others just don't care?
Does this look normal to you? (play fullscreen hd)

Mate, when opening such threads, ADD YOUR DAMN PC SPECS AND SETTINGS.

How should anyone help, replay or do anything about it without any information?

I agreed that there still appear some shimmering even if I crank up to max in AA and I am using RTX 3090 OC. I thought it's normal even in real life...I don't know. The shadow, I assume they're fine if you crank it up to a higher settings but I always keep it low (to save resource) since I don't necessarily looking for shadow accuracy when driving at high speed anyway....as long as it exist, it's good enough.

Specs becaused you asked so nicely:
HP Reverb G2, Ryzen 3700x, RTX 2080 super @v466.77,
rendering resolution was 2832*2768 per eye.

AA was set to MSAA medium and shadows to low in my last test run, now I switched both back to the maximum and it looks about the same, only the performance got worse.

Are you using Super Sampling?

I'm not a VR user (at this time) but you might check out some of the discussion for PC2 around VR:

My resolution is already high, 2832*2768 per eye, that should not be the problem. In some of my tests I had it even higher, I think it was a little bit better than but still the same problem and I can't set the resolution to 10k*10k because there is no hardware in the world that could run it :/
Might take some time to check the 300+ pages thread but thx.

the important line to edit is...
<prop name="SharpeningStrength" sharpeningstrength="0.000000"/>
the higher the number the sharper the image, too high will add strange twinkling. test and adjust to your liking.
try 1.000000 and go up from there.
on an oculus cv1 with lower screen resolution than your HMD looks best at around 1.600000

Well, this does make the image sharper but it also makes the shimmer even worse. But thanks for reminding me about this setting, I had that already set and it was maybe a bit to high, I set it to low 0.6, so the shimmer is slightly reduced (and the image less sharp), still not a solution unfortunatly.

As a VR user, I can tell you first hand that shadows and SS are a big hit to the gpu. Turn them both off (in-game) and see if this improves your performance. What is your fps when having these issues?

I honestly believe its a question of balance.

Just as in FFB so the same can be applied to image manipulation. - Less is often more.
Many players just crank everything up to the max.
For FFB many who "Max crank" will suffer clipping and end up with nothing even vaguely akin to car feeling.

The same can be said for imaging.
Manipulate an image enough and all original definition is lost .

Higher resolution headsets Suffer from the same .
It is very possible to over Sample

For a simple example :
Look at a single frame heading towards a single VR lens ( one eye)
and the optional effects offered AA - sampling, Motion blur , TAA , Super sampling All differing image manipulation sampling algorithms. -It then goes to the VR engine / compositor where yet again more sampling can take place.

Then take the "same image" from the altered VR perspective ( the other eye) Apply the same levels of sampling.
However any sampling added must generate the same perspective manipulation else your brain may well notice it . ie pixels in one lens and missing or in the wrong place in the other
- something like a moire patterning effect / false colour image etc.

One of the reasons I believe DLSS does not work well with VR .

Anyhow just a thought.

[m0rta_della]

I'm no quite shure what you mean, I don't think I'm manipulating the image too much in any way except sharpening was temporary too high. But if you think DLSS does not work in VR you are wrong anyway, because it does work wonderfully. DLSS would be the ultimate solution to performance and also image quality problems for AMS2 or just any game. Check it out in No Man's Sky, it didn't work so well on the initial DLSS release but was patched meanwile, I love it. It kills jaggies even better then TAA and offers high res image quality with low res performance, every VR game should have DLSS.

Reiza is a small team integrating DLSS would be a lot of work. I wouldn't expect it if I were you. About shadows you should be able to push them to high with your setup, also anisotropy at 8 for road readability, and AA medium and no SS. If you need SS change your steam resolution. Then image shouldn't be bad, maybe not as good in terms of aliasing than AC for instance which should allow you to push resolution more but it should be clean.

[Mahjik]

I'm not aware if Reiza has 3D engine coders in-house. My bet is that they will have to rely on whoever is providing the engine to provide such an implementation (i.e. SMS in this situation).

I think I set my sharpeningstrength="2.500000"/> and it looks sharp...I like it. I see the trees sharp in the distance which is nice. Are you saying that sharpness creates shimmering? I might have to test this out to see if it's true.

Yes, oversharpening makes shimmer worse

I have not played since a few updates but I don't remember it being to bad in this game compared to others.

My first thought for the shimmering would be the headset resolution. Since you have a G2 that is obviously not the problem.

Do you have steam SS set to auto or manual?

Max out MSAA in game see if it makes any difference from low to high. If not, maybe the AA in game is broken for VR
