t-stoff Posted May 31, 2024 Posted May 31, 2024 (edited) I've noticed when I'm over the water or in bad weather on my VR headset (not in the duplicate screen) I see these "concentric" lines (like surface lines) that kills immersion and depth. I've tried to mess around with contrast brightness, getting it darker it highlights it more, brighter helps but you can only use so much of it. If I go down low the disappear. I'm using Virtual Desktop + OPENXR and I've disable/enabled the Color Vibrance and nominal range with no effect. Also in the F4 the windshield/HUD is black in the weather (might not be related, but I noticed yesterday while grabbing screens). I've searched but couldnt find anyone with something like this - or maybe I use the wrong terms. Setup is: QUEST 3, Virtual Desktop (no ASW), OpenXR Turbo mode, 4090 7800x3D, 64gb ram, NVME. Thanks!!

WipeUout Posted May 31, 2024 Posted May 31, 2024 This is called banding. Try playing with your Gamma setting within DCS to find a sweet spot. I will not go away completely unfortunaltely. For me it is worst in low light or night missions. 1 ------------------------------------------------------------------------------------------------------------------------------------------------------------ 9800X3D, RTX 4090, 96GB DDR 5, MSI Tomahawk 870E, Crucial 2TB x 2, TM WARTHOG COMBO + PENDULAR RUDDER PEDALS, THE AMAZING PIMAX 8K X, Sony 5.1 Spks+SubW | DCS, A-10C_II, AH-64D, F-14/15E/16/18, F-86F, AV-8B, M-2000C, SA342, Huey, Spitfire, FC3.

So in a way that's kind of a relief I'm not getting crazy, even though its weird it took me this long to figure it out how its called! I'm sure (well, I think) I don't recall seeing it on my Reverb G1. [sIGPIC][/sIGPIC] "The nation which forgets its defenders will be itself forgotten"

It’s a side effect of insufficient color depth (8bit color) to render the smooth gradient. I’d you’re using virtual desktop you may find that if you encode with HEVC or AV1 (which use 10 bits) it may slightly reduce the effect. Sadly, because DCS renders in native 8bit color it’ll never completely resolve it. I get the best results (for eliminating this kind of color banding) on my quest 3 with AV1 and godlike mode, with “snap dragon super resolution” and “increase color vibrance” checked. I think the quest’s onboard chip may do some additional processing to the image that may dither or smooth out the banding a bit at those settings. 1

I'm using AV1 10bits but no snapdragon and I disabled the color vibrance to try solve this issue, gonna put in on and test it again! Thanks!

kablamoman Posted May 31, 2024 Posted May 31, 2024 (edited) Probably won’t help a ton, but I do know that it’s definitely worse with just h264 (the banding gets more prominent). Sadly, it’s there even on the headsets I’ve used with display port, so I don’t think you’ll ever get rid of it. Edited May 31, 2024 by kablamoman 1
