Before I send anything to Zendesk.
Has anyone noticed that the external lights on the Cessna 172 at least, only render on the right eye?
Also, there’s what appears to be an image, showing up at random on the right eye only for like a millisecond.
This happens after yesterday’s update only.
Im using a Reverb G2 + 3080 TI + 471.41 Nvidia Drivers.

I have also seen some large artifacts on the horizon, only affecting the right eye and only since SU5. It’s not all the time, just certain cloud conditions
Do you found a solution for that, it looks like we are the only one having this problem there. And I did not receive any response from asobo
@DDVPilot
This problem has been documented in greater details in the dedicated night lighting community solution topic. Here are some reference posts about this issue:
@CptLucky8 is right. Same lamp texture since release.
Here’s the release build early september, compared to Update 5 & Update 7. The biggest difference is the brightness falloff, “old” lamps also fading into invisibility with unchanged size after a very short distance.
Lamp sizes doesn’t scale linearly with distance, that’s the thing with point light sources, where the origin source is smaller than a pixel or smaller than what your eye can actually resolve, if it was a extended unlit surface.
Before update 5, lamps disappeared after just a fraction of what the distance in real life. But they where still the same size bulbs.
Here is a series of images to show what is creating the illusion of a bigger size, i.e. white clipping the halo.
The source image is one of the texture from XP11. It is has a bright center and a falloff. The image shows the original in the middle and the effect of just adjusting the brightness level:
NB: This is the same light bulb texture in all cases but showing as 5 different sizes in appearance.
Since it can’t be whiter than white, it will clip when adding brightness and make the semi transparent halo less transparent and whiter, adding to the ‘core’ size.
What is happening in update 7 like I’m showing is that they are increasing brightness nearby, and decreasing it farther (most likely nor inc/dec at middle distance). this gives the illusion of brighter lights close by and dimmer lights farther away, but this is wrong. They shouldn’t change brightness, they should only change size.
Now compare the light bulb above with the comparison with update 3 and 7 at RJTT:
Update 3 was still showing the halo not far away (this is a crop from the lower right of the original image) while update 7 is white-clipping.
Why do we need a Legacy / Modern Light Setting
(like Legacy / Modern flight model setting)
Regardless it is more accurate perceptually, some prefer left, some other right…
PS: of course there are different performance implications doing one approach or the other but ultimately it appears FS2020 is rendering point sprites anyhow, so in the end it might not change much between doing what they do which looks like:
they’re changing brightness using the halo as an indirect size changing effect, instead of changing size using the halo as an indirect brightness changing effect.
the former makes distant and close lights look nearly the same size and distant lights seem brighter
the later makes distant and close lights look accurately sized from each other and accurately emitting the same power.
This will probably be my last post about light bulbs sizes, but I’ve experimented trying to make them more visible and this is really interesting comparing the different approaches vs the photo. Here is:

NB: you have to open these images in their full size to really see the details!
A few quick comments on what I see:
fs2020 update 7 is rendering almost all “street light” bulbs at the same size, whatever the distance to the viewer. In addition the emboss filter is showing sharp edges which means they are very bright with very small halo. There seem to be “types” of lamps each displayed the same size and same way (all taxiway bulbs are rendered the same, all street bulbs the same, etc…)
fs2020 update 3 is rendering smaller street lights in the distance which is good, and the emboss filter is showing more fussiness revealing a wider halo. However it looks like their size vs distance is not linearly distributed like in the xp11 shot. Instead it seems they are displaying by LOD rings (all lamps in LOD ring 1 are the same size, all lamps in LOD ring 2 are same size). Otherwise if not by LOD rings there is some form of ‘clustering’ of same size lamps.
xp11 is rendering street lights with size varying with the distance and all lights are softer than fs2020 indicated the rendering of the halo around the light even for the closest ones.
real photo is showing more variation in light sizes but it shows there is a correlation still with light size and distance to the viewer. Furthermore, some of the lights are as sharp as the ones in fs2020 but most are fuzzy like xp11
@AlexE75 has posted a series of screenshots exhibiting the latest WU3 outline/edge bug around objects lying in front of clouds and I find there is some very interesting visual info about the night lighting issues we’re discussing here*.
Some comments:
It seems to me the halo around light bulb is displaying better than the last time I visited this topic.
Light intensity attenuation with ambient lighting is really credible, but I believe lights are still too large at night . This is even more disturbing in VR than in 3D.
Light size still doesn’t decrease with distance and it is making them a nuisance in VR where the most distant ones are creating a soup of light.
I believe if there would be only 1 thing to change first is light size with distance. And this is where these screenshots are really interesting to me because the reflection distortion along the longitudinal axis of the aircraft is showing exactly what would the green lights look like if their size would decrease by distance, vs the white lights on the edges which are not.
I don’t know for you but to me, the varying green light size is much more realistic (and they’ll solve the light soup problem).
*I’m reproducing some of the screenshots here in order to make it easier to follow through but the original link to the topic is found below and worth looking out: you can cycle an entire day time span and see how this affects runway lighting rendering.

Here’s another comparison of the different night tech versions we’ve seen so far…Early Alpha Release Build Update 5 Update 7 - World Update US (November 2020, nothing significant have been done after this)
Here’s another location I’ve been using to compare night tech of different versions.
One of the biggest problems with the release build up until now, are the blurry oversized lamp texture… Instead of being small sharp light sources at greater distances, we have huge fuzzy orbs that fade in transparency while still being huge at a distance. It’s almost like the devs have used telephoto night photos as reference with severe “out of focus” lamps in the background as reverence. Just look at this crop, IRL lights would be sharp small lights with fading size & brightness, not big fuzzy orbs with fading transparency and constant size:
In my opinion this is still wrong for all the wrong reasons already documented in this topic: they don’t change size with distance thus the farther the light, the higher the perceived intensity but also, and especially in VR, the farther the light the fuzzier it is.
I’m still convinced the best technique would better be:
a core opaque bulb with a halo.
the closer the light, the bigger the halo (brighter and fuzzy - glint effect)
the farther the light, the smaller the halo (dimmer and sharp - in the distance effect)
ambient lighting could still affect halo size if up close (appears less bright and sharper/smaller)
ambient lighting might not need to affect intensity if distant, otherwise just dim the intensity of the light pixels.

I try to turn off hardware-accelerated gpu scheduling in windows game setting, and the checkered patter is now fixed. I will do more test tonight.

Thank you all for your kind replies.
Can confirm that disabling gpu scheduling makes the ‘ghost image’ that pops up at random is now gone.
BUT
Reflections on the windshield (?) only render on the left eye. Tried different planes and no reflections on the right eye, no matter what.
Anyone with this issue?
