The moon is too small now (in VR)

IPD should always be on your personal eye distance. This setting changes the world scale as perceived from a normal adult human to a toddler or a giant. Everything close to you in the cockpit will get bigger or smaller but it doesn't do anything to size perceived for very distant objects. Which makes sense and i also double checked if there is anything wrong with it.

When inside cockpit good outside not so good but would rather have the right size in the pit for me personly,.as for them moon not  been in vr night mission for a while so..

Well, here the moon is only an indication that something is off. Spotting of distant objects is problematic in general in VR. FOV not set right could act as a problem amplifier. Sadly we can only change IPD but not FOV to check.

That question kept me thinking and i got the idea for an experiment. Highly inaccurate of course without knowing on what values the cameras in DCS truly operate.
There is this tool which is pretty famous for being used measuring your VR HMD's optical FOV in a calibrated space.
https://knob2001.itch.io/testhmd

To get your horizontal FOV measured, you have to stare at the center of an image with two red bars left and right. Then you move those bars further and further into your peripheral vision until you can't make them out anymore. My current HMD gives me a result of 110° (depends on personal face shape and eye position).
So i did a simple test in DCS. Prepared a date and time with a full moon close to the horizon, centered my heading on it and started turning sideways until i reached 55° more (233° -> 288°). Always kept the yellow cross of the fixed mouse cursor in the center.

The moon was leaving my field of view at 292°. This basically means that DCS renders a FOV of 118° on my headset with 110°.
Would be nice if someone else could test this too on his end...

On top of that, i talked to a former Tornado WSO which also uses VR in DCS too and gave him the test mission. He said, from his memory, the moon definitely appears to small in DCS. By 30-50%.

 

Hey RealDCSpilot!
It's very interesting to see that someone is digging into something so deep.
On the picture you shared (F-18?) it seems that the moon now shows at a "size" of ~1.6° of azimuth.
I think I will try out the test which is linked above when I am back home, this question is interesting for me as well.

Thanks anyway for sharing your thoughts and observations.

Regarding the IPD setting in game is virtual IPD not real IPD many ague it's the same for me if I set to my real IPD all pits are different, but I am going off topic.

No, the azimuth ruler at the top of the HUD is not to scale. The pitch ladder is correct though and can be used for such measurement.

Yeah, on one side it's cool to have the option to modify. But this is also another indication that DCS might do a little sidestep here and doesn't follow the rules. Personally i do not use it, this should all be managed by the OpenXR API. It takes the value you mechanically set in your headset and reports it to the game which should adjust it's camera rig accordingly.

Thanks for starting this topic RealDCSpilot. 

It saves me the trouble.

The moon is obviously way too small now. Anyone who looks up should be able to see this. I can't believe that anyone is arguing with you. It detracts from the sim. Devs.... just fix it ... OK?

Yes, we all know how big is the moon and it is correct now in DCS.

I just  got done flying on a server ..........It's too small!

Reduce the fov then.

This.

Also keep in mind, that the apparent size of the real moon varies quite a lot depending on your location and the time of month/year. (Almost 15%)

Sadly this only works for 2D monitors, for VR there is no option to access such a setting.

In VR you need to adjust the IPD in DCS to scale the world. (I assume that includes the moon)

[RealDCSpilot]

No, this doesn't affect any far away object. Rendered FOV is something very different than eye distance.

Because the fov is correct in VR. No need to adjust. So is the moon and sun size.

[RealDCSpilot]

I have my doubts. The appearance of the moon in my headsets leads to the conclusion that something is off. First suspect is a slightly bigger rendered FOV than the screenspace demands for being 1:1 with real world perspective.

It's just a feeling due to low resolution - lack of details - compared to RL. It'd have to be huge difference of fov to notice and other things would look bad too.

[RealDCSpilot]

You still not understand. If i could bind the VR spyglass zoom to an axis and just move the lever from 0% to 5% or something, i could demonstrate the issue perfectly.

meh...

Even after the latest update the Moon appears ridiculously small. It looked better when ED made it too big. As it is right now the Moon is so small that it is easily mistaken as an enemy plane during the confusion of a heated WWII dogfight when scanning the sky for the bandit, when fractions of a second matter.

Zoom in, it'll look better.

[aceviper]

The zoomed out flat earthers say its right.

The amateur astronomers (me included)say its too small in VR.

Human eyes perception or zoomed out alternate reality?

Moon is ok but stars are in some random position, can't find any recognizable patterns there.
btw in msfs2020 this goes opposite way: stars are more or less in place and moon is out of place and scale. pic for the lulz:
