Baseline (Widescreen) Solution & Issues
All cutscenes are in ~21:9, anamorphic.
A field of view slider is available in the settings, ranging from 30 to 70. It is set to 70 in the screenshots.
Ultra/Super-Wide (21:9/32:9) Specific Solution & Issues
The rendered cutscenes are pillarboxed and kill cameras are windowboxed at 32:9. Rose's tools allow to remove the pillarboxing. The frequency of kills resulting in kill cameras can be adjusted, or they can be disabled altogether.
Eyefinity / Surround Specific Solution & Issues
The HUD gets centered once the game detects a multi-monitor resolution, including 4320x1080 and 5760x1080.
The cutscenes are affected by the same issues as in ultra-wide and can be corrected with the same tools. See the Additional Screenshots for the demonstration.
