Marked as "spoiler" because it flickers a ton. In this video I'm not moving at all—the flicker is basically constant when moving my character around.
I've tried changing STO's display and graphics settings quite a bit (from potato to "all the bells and whistles", from windowed to fullscreen, etc.) and nothing makes the flickering go away.
Other games (Cities: Skylines, Dorfromantik) do not flicker.
Note that UI (dialog boxes, etc.) don't flicker.
This is particularly frustrating as STO is basically the only reason I bought this computer.
I've posted in the official forums about this too, and I filed a support ticket (#553257).
