Thank you, Tippis and Flappie, for all the help. Indeed, it was a Crossfire issue. Once upon a time, ATI let you enable/disable Crossfire on a per-game basis in the profile. -- no longer. You have to disable it globally or not at all. That really sucks, because for games that use it, you have to re-enable it just before you start. I might as well throw an extra monitor on now, until I get a good VR set. Thanks again!

I tried all those, but had to change to the display. Since I deleted the ED folder on the game drive and the DCS folder in SavedGames, it leads me to believe something was saved in the Registry that isn't removed during the uninstall.

Thanks, Tippis, for the suggestions. I'll give them a try, but I'm not optimistic, since I deleted the DCS folder under SavedGames when I reinstalled. But, I'll let you know how it goes.

I had some stuttering, so I tried reducing a few settings to pick up some extra FPS. When that didn't work well enough for me, I tried changing from High, to Low, figuring I could work my way back up. On Low, the screen looked almost like sepia tone, sort of like 256 shades of brown. Except for the sky, which was black. The clouds were still white. Since then, different maps looks like shades of green, or still brown, but the sky and clouds remain black and white. The Dashboard background is always fine. I created a profile for DCS in Radeon--no change. I tried repairing through WinPS. I tried Cleanup through WinPS. I uninstalled, deleted everything I could find (I didn't search RegEdit), and reinstalled. Nothing changes. I only get brown shades, or green shades, except I get what looks like twilight, with the last vestiges of daylight disappearing over the horizon, even at 0800. And of course, the sky is black and clouds white. Ryzen 7 / 2700X, dual Radeon RX580 (8GB each), 64GB RAM, 4k SamSung monitor (3840x2160). Tried with an without Crossfire. But the palette was fine when I initially installed. The old equipment affects FPS, for sure, but not color or resolution. Is there a registry key I need to delete that the game keeps reading with the old data?
