Game mode: Singleplayer
When I first launch Conan Exiles and arrive at the main menu, the display is tinted green and flickering. The green flicker will carry through to the game. However, I’ve found a can get rid of the flicker by going directly to display settings, changing the resolution to something else, clicking apply, then immediately reverting back to 1920x1080. Once it reverts back, the flickering is gone. The green tint is gone. The game runs fine.
I’m running a GTX 1070 and the game runs nearly perfect on ultra settings once I’ve managed to get rid of the green flicker. The workaround I’ve described isn’t terribly onerous but I suspect it wouldn’t be that hard to tweak something in the initialization process to make display work the same as they do after changing the resolution.
