Blurry game any help?

[NPC]

I feel near sighted when i play this game. For some reason things looks crisp up close but 3 feet ahead of me everything becomes really blurry and hard to see like I am not wearing glasses. I disabled Dynamic resolution but that didnt change anything. Im using a quest 3 and have a 3080ti

Turn OFF TAA ( it's on by default ) . Turn on Super Sampling you have a 3080Ti so you should get a fair boost to image quality.

Additionally

You will always get a "screen door" effect because you are physically close to the miniature screens in the headset - that's common to pretty much everyone. Maybe not on the very high end headsets but average ones for certain.

If you do actually wear glasses as well then your best friend when VR gaming in general is a set of prescription inserts for your headset.

Never underestimate the value of a counterweight - you can buy them for various headsets but I recommend making your own - Coins, duct tape and velcro work just fine

Blurryness in VR has a long list of reasons:

1. VR headsets that do not have a real Video port. Like Quest. use compressed video. compression artefacts look blurry. Compression has a problem with noise. It destroys noise (or tiny detail) into blurry mud. SkyrimVR has a lot of noise (the foliage is very noisy). Also, things in a distance are more noise than things very close.

What helps: increasing the bitrate (less compression). You get the highest bitrates by using a cable. But even the highest bitrate that a Quest 3 allows to be used, does not completely remove the compression artefacts. Wich results in several Valve Index (real video port = no compression in video) users, that I read comments of, that upgraded to Quest 3 to complain about blurryness in the distance.


2. Dynamic Resolution
In theory the idea behind it is good. It reduces the resolution of the image, if performance is bad. Half Life Alyxs does this aswell and it does not give you the choice to deactivate it. Difference is: in Half Life Alyx it works perfectly. In SkyrimVR its broken and you are on a lower resolution for most of the time even in high end PC.

Solution: Deactivate it (you already did).

3. TAA
TAA is an antialiasing wich is very cheap (consumes very low performance cost). But its insanely blurry. Wich is specially visible in VR. Its also not as effective in removing aliasing and shimmering as say DLAA (an Antialiasing based on artificial intelligence). You can get DLAA with a mod. this one:
https://www.nexusmods.com/site/mods/502
and it needs this too: https://www.nexusmods.com/skyrimspecialedition/mods/82179
And the DLAA files (they did not have the rights to make it part of the mod): https://www.techpowerup.com/download/nvidia-dlss-dll/

DLAA is as blurry as TAA though. But zero shimmering. And it costs huge amounts of performance.

Solution: Either you deactivate TAA (or DLAA) complete. Wich results in a sharp and crisp image that has aliasing and shimmering from hell.
Or you use a sharpening filter, that sharpens up the final image before its delivered to the headset. (note that sharpening adds noise to the image wich can again be problematic in headsets that use compressed video)

There is a lot of sharpening solutions for SkyrimVR. One is build into the DLAA mod. But there is other. And you can stack some of them, if its still not sharp enough.
I use the DLAA sharpener at maximum (1.0) and the sharpener in Glamour Reshade at 0.4

Here is an example of what to expect of a sharpener filter (in this case, its Glamur reshades sharpener):

4. AAF (anisotopic filter)
The anisotopic filter sharpens textures that you look at a flat angle on. The floor for example gets so more flat, so more far the distance is. SkyrimVR uses 4x AAF by default. You can force 16x AAF in the NVIDIA panel.

this image shows the difference between high and low AAF:

5. Supersampling/Upscaling
If your PC does render at a resolution lower than the native resolution of the headset and is upscaling it, the image will be blurry. Thats even the case if you use modern upscaling like DLSS (wich you can try with the same mod that offers DLAA).

Better is to always render at MINIMUM the native resolution. Its even better to "Supersample" (rendering in a higher than native resolution, wich results in a more crisp image).

6. More unknown is a setting in the ini file.
I am however unsure if this still makes a difference. Back in Valve Index it did. I could not see any difference anymore when I upgraded to an Index, but I keep the setting. (and its still a recommended setting in a list on the SkyrimVR ini settings.

[Imagespace]
bDoRadialBlur=0 - disables Radial blur which is a particular kind of blurring effect

This setting made a difference in the clearity of distant mountains to me, back in the Vive era.

A different source even deactivates more of these types of settings, where its unclear if all of them are even active in the VR version or not:

[Imagespace]
bDoRadialBlur=0 - disables Radial blur which is a particular kind of blurring effect that
bDoDepthOfField=0
iRadialBlurLevel=0
bDynamicDepthOfField=0
bMBEnable=0
bScreenSpaceBokeh=0
bLensFlare=0

screen door is only on those with terrible vr, the vive headsets like cosmos elite and pro 2 and pro dont really have those, can't speak for the garbage index

Well, the ppd (pixel per degree) also says something about image clearity.

Its how many pixels fit onto 1x1 degree FOV. The ppd numbers vary from source to source though.

Roughly like this:

original HTC Vive or Oculus Rift 1: 7 or 8 ppd
Valve Index: 11 ppd (thats the ppd that 360p on a monitor would be)
Quest 2: 18ppd
Quest 3: 22ppd (thats the ppd that 720p on a monitor would be)
Pico 4: 25ppd
Pimax Crystal: 35 ppd (thats the ppd that 1080p on a monitpr would be)

Flawless in an eye doctor test: possible with 60ppd and upwards

4K Monitor: 70ppd
Average human eyesight (reading very tiny numbers test): 80ppd

Samsung Galaxy Ultra Smartphone: 120ppd

Good human eyes can detect 2 squares not perfectly lined up but 1 pixel difference between both: up to 650ppd

A star is 1x1 pixel in size at: 70000 ppd (and humans still see stars)

this is unique to this game. I've done all the fixes some that are not listed here and this game is always blurry. almost all other vr games including older ones look clear.

strange, but good to know it wasnt just on my end. Do you know if fallout VR is the same?

If all fixes do not help, the blurryness you see is caused by video compression.

Most VR games use very clean and simplified graphics. Means they have very low noise. Thats good for video compression.

SkyrimVR (and Fallout 4 VR) have extremely detailed and noisy graphics. (the leaves of the trees and the grass is the worst)

the Video compression of say, Quest headsets fails to keep these noisy details and creates a blurryness that is often seen especially with distant things. And that is not the case with headsets that do not use compressed video streams but have propper video connections (but these are usualy of older date and have lower resolutions)
