Ultra/Super-Wide (21:9/32:9) Specific Solution & Issues
You need a hex editor and the ResHex app.
- Input your resolution settings in ResHex and copy the resulting Combined Hex e.g 8EE31840 for 3440x1440
- Hex edit Assembly-CSharp.dll found under Steam\steamapps\common\june\LastDayOfJune_Data\Managed\
- Search for hex string 398EE33F and replace it with 8EE31840 (9 times) for 3440x1440. Save changes.
- The first time you run the game, enable/disable windowed mode to update the aspect ratio.
Performance tip: use launch options -screen-width -screen-height with a fraction of your desktop settings e.g -screen-width 1720 -screen-height 720 for 50% scaling at 3440x1440
In 'regular' aspect ratios you would select a lower rendering resolution to increase performance. This is not possible in UltraWide: only your native resolution is available because every so-called 21:9 resolution has a unique aspect ratio...
2560x1080 is 64:27
3440x1440 is 43:18
3840x1600 is 12:5
Eyefinity / Surround Specific Solution & Issues

4k UHD Specific Solution & Issues
