Flickering screen/ unstable picture/ mostly black screen.
This happens under several conditions:
- In monitor settings DisplayPort mode is set to MST. Usually SST (Single Stream Transport) mode is on - in this mode picture is stable. In my case with MST (Multi-Stream Transport) mode my videocard NVIDIA GTX1070 is initialize normally in the UEFI bootloader)
- G-Sync is on.
If you have these conditions, to avoid flickering you should turn off G-Sync for this game only in the NVIDIA control panel settings or switch DisplayPort mode in monitor settings to SST.
