I purchased a Surface Book 2 last summer and have struggled to get optimal performance in FFXIV while running in windowed mode. After playing with various lower resolutions I discovered that there is no support for a custom resolution at full screen, and also no lower settings for the weird 3:2 resolutions that Microsoft decided to put on this device.

Is there a way to set the screen resolution in XIV to 3:2 outside of the baked in resolutions under graphics settings? If not, are there any plans to support the lower 3:2 resolutions?

Resolutions needed:

3240x2160 (supported only at full screen)
1920x1280
1800x1200
1728x1152
1440x960
