Strange Lighting Issue (Colour Banding)

First off I know theres compression in the images which doesn't help convey my issue but I'll try and explain if it isn't obvious. As I was playing I noticed that the sky had this kind of oil slick appearance where the light of the moon starts to drop off there is a kind of gradient. It's really noticable especially as it gets closer to the horizon line. I took this screenshot and transfered it to my phone (i don't have another monitor). Same results.

Running at 4k
Nvidia RTX2080Ti (Although I had a 980Ti when I saw it in RE7)
I checked out my display settings in the Nvidia control panel currently 32bit colour depth / output at 8bpc. Output colour format is RGB and Output dynamic range is Full.

If anyone can advise I'd be very appreciative. Thanks.


**EDIT**

Apparently it's known as colour banding and it's common in games. I was hoping to resolve the issue but I think it's hardware related :(

You are on 64 bit, possible it's the cause

I would say that it is a hardware issue. I dont have this issue as of yet. I added the files to make the game 65bit. The game is pretty much flawless for me, except the part where my game doesnt use more than 1.6gb of memory (which bottlenecks my game hard as ♥♥♥♥ in Open areas with buildings). Im using a gtx 1070 16gb mem, and i7 quad 4.0gh with a 4 year old top of the line intel SSD. Ive seen non of those issues you have mentioned. I did have flickering when I used motion blur, but i turned it off and I dont get flickering.

BUT, I just read that you had a 2080ti ♥♥♥♥♥♥♥♥♥. lmao. when I first read this, I thought you where talking about an AMD card LMAO.

Yeah, It has to be hardware issue, since thats an extreamly new and powerful car that has new tech on it. that htis game during its development probably never thought would happen. I would give it another Geforce update or two. And see if the issue is still there. Also just incase TRy playing in Window mode. I have to play in windowed mode, otherwise I get weird issues when in full screen.

I know non of what i said will help. BUt hey, tbh try windowmode, and turn off motion blur. If that doesnt work, try turning down the volumetric effects down, and maybe postprossesing. Those are all the things t hat would cause weird lighting issues I think

it's normal, games use compressed textures which results in slight color shifts on each band (blue vs purple)

but even if textures were uncompressed, even if this was photoshop, banding will happen because there arent enough colors

think about it, you have a gradient from 30 bright blue to 50 bright blue out of a total of 256 brightness levels (8bits per color 3 colors rgb = 24bit color aka 32bit to have 256 levels of transparency)

so you end up with only 20 brightness levels to choose from that you're trying to display on a monitor with thousands of pixels, meaning you divide the height resolution by 20 to end up with the size of each band (straight gradient in this example, game is more like a curved gradient)

the only way to make it less obvious is to dither it, making dots of the two bands so that it's not a hard line, imagine retro games from the 80s to early 90s, they dither a lot

this is one thing 10bit or HDR monitors may be able to solve in modern games that support HDR, same issue with movies/video files or photos

for older monitors, if you use a cheaper 6bit monitor instead of decent 8bit, you will have even worse banding than what the game/movie/photo is displaying

the steam client also has obvious banding in certain areas
