Game looks pretty good. Hor+ & FOV looks proper. HUD & text perfect. Rendered video spreads full perfect. But minor issues *.
(PLP screenshot with bezel effect)
In game launcher, windowed & settings how you want. Edit %APPDATA%\StokedBigAir\userdata\gpu_settings.config (Notepad, backup original). resolution_height_ & ...width_= your base PLP resolution. ShiftWindow (+ border = borderless & to position).
NOTES:
1. * Minor issues:
A. A few flat visuals are stretched:
i. Startup logo, flat loading screen image.
ii. Screen bottom's frosting overlay. Seen on main menu (first page), Customizer screen & during some helicopter's rendered video.
iii. FMV video. Seen in Scrapbook page & Credits, sometimes at challenge completion.
B. Scrapbook videos page is basically broken, so watch in single-screen (using backed up gpu_settings.config).
2. If game won't boot, uninstall PhysX & install old version (from game's release, version 8.09.04 tested working).
(comparison. Notice the falling snow difference on sides; it was windier at the time, but game's FOV also contributes)
(1080p)
(main menu. Notice stretched frosting overlay at screen bottom)
