Game spreads full hor+ & FOV proper, in all view distances. Aim reticle proper. Rendered video hor+ (sometimes letterboxed). Other areas bit ugly *, but decent spread & none a problem.

1. In launcher, Display mode: Windowed (not WindowedFull) & then select the biggest resolution allowed. Save.
2. In-game (every restart):
A. Click gear icon (top-right, may need to hover), then Graphic.
B. Uncheck "Window border".
3. ShiftWindow (fullscreen resolution = borderless).
(main menu)
NOTES:
1. * Most text stretches. Main menu elements span full width, rendered proper on center & stretched on sides. HUD stretches, its element-positions spanning full width.
2. SoftTH does not work, both game & launcher abend.
(example of interface looking stretched & ugly)
