Much less banding without HDR

[hjsmuc 393]

I noticed that the banding effect of the sky is much reduced without HDR. Any expert here who can explain why? I read about methods of dithering with Bayer Matrix and the like but that's way beyond my comprehension. What I would like to understand is whether the bug is in the HDR shader or in the skycolor png's (or in both). Thanks for an explanation.

It's a known issue.

Don't waste time for a bug they will fix, and most important NO HDR = NO PARTY for me in XP. I will never sacrifice HDR for performance, it's what change XP in a light breathtaking experience.

Sure, it looks way less nice without HDR. This banding is just horrible, it was eliminated in XP10 at one point in time and now it has sneaked back in.
