The story is this: Ryzen 3600, Radeon 580, Win10LTSC, LCD panel 2560*1080, Adrenalin Software 20.9.2 and 20.11.2.
When I flip the display using Windows, I see a terrible drop in FPS (10-15) in WarThunder. If I put the normal position, everything works correctly. Obviously we have a bug in the drivers. Don't ask me why I'm flipping the display, that's the way. What do you advise?
