"Patches"" of color rather than shades.

[greybeard1]

When there is little light (dawn, dusk, rain, etc.), I'm getting landscapes (especially sky, clouds and sea) divided in areas of slightly different colour (or light), each with its own "border", instead of a continuous gradient.
In the past, I saw this defect when trying to render a higher colour depth image with a lower colour depth display.
Here follows related section of my conf.ini file; I would ask an help to solve this issue.

Imho its a 'new nvidia driver vs old game' issue but I'd also check my monitor settings.

[greybeard1]

Thank you very much for prompt reply.

Actually, I recently updated my NVidia driver (although I think that issue was already present).

It's a long shot, but are you sure IL2 is running in 32bit color mode?

It can't be set from inside the game, only in il2setup.exe. Either have a look at that or check this in your conf.ini:

[window]
ColourBits=32

If that value is 16 instead, that's likely to be your problem.

[window]
ColourBits=32

If that value is 16 instead, that's likely to be your problem.

That section of my conf.ini reads:

ColourBits=32
DepthBits=24

[Pfeil]

That looks correct. I did say it was a long shot.

Sometimes its only your monitor. Most of payable actual monitors lack technically in enough color depth (although they call it 32bit), which leads to a bad display of color, especially in the dark to very dark range.

Your problem sounds much like that case.

Do you see stripes on this pic or is it a smooth blending?

Thats the reason, why I haven't thrown away my old CRT yet BTW...

Well, it makes no sense, indeed, since this is a laptop I use just for the Internet while I play IL-2 on a different one, not connected.

I think it's purely matter of graphics, though; would attach here a screenshot, but can't load from my HD.

Dont worry Graybeard, I get the color banding ingame but not in Photoshop hence its not the monitor! Its the nvidia driver 100%!!
Even in 24 bit you got 16,7 mio colors so why would that break a blue to lightblue sky gradient? :grin:

[greybeard1]

Thank you all for kind help.
