Setting fullscreen resolution to 1920x1200 keeps the game rendering at 3840x2400

[Milklord]

Game Version​

[e.g. 2026.10.13.5602]

Operating System​

Windows 11

What Happened​

Setting fullscreen resolution to 1920x1200 kept the game rendering at 3840x2400, seen by UI scale staying the same, graphics looking the same, and game still running very slow.

What Was Expected​

Setting fullscreen resolution to 1920x1200 would render the game at 1920x1200. Monitor is 3840x2400, so I would expect borderless windowed to do this but not standard fullscreen. Setting to regular windowed set the resolution to 1920x1200.

Reproduction Steps​

Either:

1. Start game
2. Go into settings
3. Change resolution to 1920x1200 fullscreen

Or:

1. Start game after setting game to 1920x1200 fullscreen previously

Reproduction Rate​

Always

Additional Info​

It would be awesome if there was a setting for render scale - that way it's easy to just set render scale to 1/2 so UI is 4k while the graphics render at 1080p. I know KSA isn't at the optimization stage yet though, but looking forward to the optimizations once it gets to that stage!
