Bug #25992
Shadow Flickering and banding
0%
Description
Upon the suggestion of the Private Division tech support team I'm reporting this bug. Apologies if it's already been reported.
Description:
at certain angles at ground level on Kerbin, severe shadow flickering occurs. At it's worst, dark bands cross the entire scene at various distances from the camera. This problem subsides as the focused craft launches and ascends higher into the atmosphere.
the tech support team report they've seen this issue on Nvidia cards before but don't have a fix for it. There are also posts on the KSP forum reporting the same thing but no solutions have been found. The only common denominator is Nvidia cards but no particular generation - the problem persists on both GTX and RTX series GPUs. I've encouraged those forum posters to report here too in the hope of providing enough info to find what the problem is.
My game is a fresh install and new game start. I also have a 'clean' install of the latest Nvidia drivers.
Although I can't change the severity of this bug to 'severe'' I could definitely describe it that way as it is totally immersion breaking.

Same problem, very immersive breaking.
It happens at any zoom but these screenshots are zoomed out since then the problem is more ''stable'' and a screenshot is possible.
Up close it flickers so fast....ugh....please try and fix it....

Updated by Same problem. Turn off the shadows kind of works, fixes big black lines, but leaves shadows flickering.

First I thought it's because of visual mods - but it's not.
GTX 660 here.

Immersion totally broken and I can't film the ISS Challenge after days of work.
And will have to stop streaming this game at because it just looks terrible. And its not the quality I can serve my viewers.
Tried everything on hardware side.
Even swapped my Gigabyte 1070 GTX with an MSI 970 GTX with the same result.
My test ISS added to the files.
Setup:
Windows 10
Steam install
Fully stock Both DLC's
1.9.2 1.10.1
X3600/Asus X370 Prime/ 32GB RAM Corsair /Gigabyte 1070 GTX and tried MSI 970 GTX
Update! Anth12's post seems to clear the shadow banding! So go and check your settings.cfg file folks.
I am still testing but it seemed to work!

If the settings.cfg file is upgraded from 1.7.3 to 1.10.1 then the settings will be as follows and the banding doesnt happen:
Upgraded NO PROBLEM
SHADOWS_FLIGHT_PROJECTION = 1
SHADOWS_KSC_PROJECTION = 1
SHADOWS_TRACKING_PROJECTION = 1
SHADOWS_EDITORS_PROJECTION = 1
SHADOWS_MAIN_PROJECTION = 1
SHADOWS_DEFAULT_PROJECTION = 1
If the settings.cfg is deleted and KSP recreates it from scratch in 1.10.1
Clean Install PROBLEM
SHADOWS_FLIGHT_PROJECTION = 0
SHADOWS_KSC_PROJECTION = 0
SHADOWS_TRACKING_PROJECTION = 0
SHADOWS_EDITORS_PROJECTION = 1
SHADOWS_MAIN_PROJECTION = 1
SHADOWS_DEFAULT_PROJECTION = 0
Clean install or the rebuilding of the settings.cfg causes the bug to happen because of the above settings
