unipus Posted December 15, 2016 Share Posted December 15, 2016 I'm trying to record some video, and noticing that there's some sort of vignette filter applied over the image in dark/low light conditions. The problem is that filter seems to be low-bit so there's really obvious gradations that are frankly kinda killing my video buzz. Anyone know how to disable or alter this effect?

unipus Posted December 17, 2016 Author Share Posted December 17, 2016 ...? Or anyone have any idea a better term to describe what I'm talking about? Link to comment Share on other sites More sharing options...
unipus Posted January 14, 2017 Author Share Posted January 14, 2017 Might as well bump this. Haven't had much time for DCS the last few weeks but never got any closer to figuring out this problem in any case. Link to comment Share on other sites More sharing options...
zaelu Posted January 15, 2017 Share Posted January 15, 2017 There is no overlay. It's how it looks when the light dims out. It's like an artefact of compression... like instead of 8bpp it shows less... 6 or even less. Try putting one single plane on a mission on an empty airfield (Anapa is a good one) and then just accelerate time really really much and watch the night setting.

unipus Posted January 18, 2017 Author Share Posted January 18, 2017 Why would there be compression? Why would the bit depth degrade? And only around the edges of the image? That doesn't make sense. Link to comment Share on other sites More sharing options...
GeorgeLKMT Posted January 18, 2017 Share Posted January 18, 2017 Do you have a screenshot on hand? I haven't noticed any overlay like you described. Only issue I know about is color banding, where there are visible color steps in the skies, and we can only hope they'll fix that in 2.5. ■ L-39C/ZA Czech cockpit mod ■ My DCS skins ■ Link to comment Share on other sites More sharing options...
Kuky Posted January 18, 2017 Share Posted January 18, 2017 It's like an artefact of compression... like instead of 8bpp it shows less... 6 or even less. That's what I think it is also, I think game is not running full 32bit color, I even reported it long time ago but nothing ever came out of it. No longer active in DCS...

Cobra847 Posted January 18, 2017 Share Posted January 18, 2017 The banding effect is caused by a lack of dithering. It's not something easily solved. Here is a dithering implementation by a AAA title recently that illustrates the issue and solution: https://imgur.com/a/tVrWL Nicholas Dackard Founder & Lead Artist Heatblur Simulations https://www.facebook.com/heatblur/ Link to comment Share on other sites More sharing options...
unipus Posted January 19, 2017 Author Share Posted January 19, 2017 I deal with banding issues in my job as well (VFX and design, among other things) and the usual solution is to add a very small amount of noise. Not sure if that would work within engine. I will try to take a screenshot very soon and post just so we're all definitely on the same page.

Mustang Posted January 19, 2017 Share Posted January 19, 2017 (edited) Night vision goggle effects show the banding at it's worst, it looked much much better in older DX9 engine. P.S: I already made a bug report for this a long time ago, but it's never been looked at (Mantis: 32454) Edited January 19, 2017 by Mustang 1 Link to comment Share on other sites More sharing options...
