So i did fresh install of F2 + updated Sfall and unofficial patch from Killap - now 2x scaling does not work in 1080p resolution =(

Screen settings shows that i have basic mode (even if i don't? DX9 enabled)

Seems like i need to set mode to 0, not 4 and scaling now works, strange.
[Graphics]
;Set to 0 for 8 bit fullscreen
;Set to 4 for DX9 fullscreen
;Set to 5 for DX9 windowed
;A DX9 mode is required for any graphics related script extender functions to work (i.e. fullscreen shaders)
;Modes 1, 2 and 3 are no longer supported
Mode=0
