spotting in the Rift -recommended settings?

[VRPilot]

Hi,

 

I set pixels to 1.5 in SteamVR an AA to off in the game. Image (and performance) is good, but contacts are very very small and disappear (or at least it feels like it).

 

Any recommended settings to improve spotting?

 

-having all settings to default I have no probs with spotting, contacts are kind of big blobs in the distance, but image quality is ****

-ingame AA is **** too, so I try to avoid it

-Oculus try tool SS seems to have a very different effect compared to steamVR PD (--> what's the difference?)

 

Thx for any tipps!

See this link where the difference between the two are discussed.

Running higher levels of supersampling is a compromise between spotting and identification/clarity.

 

There is no magic fix available to us that will improve it.

thx. may I ask what settings you use? Ingame and PD/SS ?

 

I run also an i7 7700k + 1080TI myself.

From memory, (not near my gaming PC at the moment).

 

SS set to 2.3 via SteamVR (I use a Vive).

No AA,

High Detail

Medium Shadows

Lowest Grass Render range

Highest Terrain detail range

 

I used to run it at Ultra, but I'm finding way too many maps on WOL that have high overcast clouds that are hurting framerate badly even at my current settings.

Same map with different cloud setting seems to run smooth.

thx! I'll try it and report back!

It is an interesting question for spotting. I have not tweaked with that.

 

For identification, I have tested with the two main variables: ingame AA and SS. The results were reported here:

https://forum.il2sturmovik.com/topic/32186-identification-vr-supersampling-and-aa-influence-sample-imag/

 

There is a third variable to play with (Sharpen on/off). But I don´t know the effect for ID or spotting.

 

It would be good to run a number of test with different values of AA and SS with a very distant a plane (a small fighter and also a bomber) to know exactly how they are influencing in the spotting.

 

Theoretically if you increase SS you are sampling more pixels for the same scene and then the resulting image is subsampled to fit into the Rift display. This could reduce the number of final pixels that are coloured in dark (assuming the plane is dark color and the sky is clear color).

 

Then the AA filtering is applied later to smooth the image before going to the display. The effect is bluring more the dark dots.

 

So higher SS is good for reading text, gauges and object details, but it will affect negatively for spotting.

Then, AA is good to remove ugly edges if they are still present, but it will affect negatively for spotting.

 

Using a good number of SS remove most of ugly edges (since SS can be considered also as a AA technique, but very heavy loading GPU), so there should be no need to use AA at all.

 

In summary: Not use AA at all. Then go to a SS number to get good clarity to read gauges/text but not too high to decrease your spotting ability.

 

For a 1080Ti card you can go well until SteamVR_SS=3.0 but the right point could be better in the rage 2.0 to 2.5.

In any case, a good test images matrix with SS and AA number will help to objetively quantify the effect.

1.5 SS in Steam VR is not very much.

That same SS in Oculus, would be 2.25 in Steam VR.

So comparing images with the same value of SS in Steam VR then Oculus, is not an equal SS.

 

I personally run 1.5 SS in Oculus (via the Tray Tool), 4xAA, and sharpen.

I don't have too much trouble spotting but struggle with target ID. I fly SP only so I have no shame, I toggle labels on if needed.

 

This is some limitations we have with first generation VR devices, as the technology improves with future generations that should certainly get better.
