I have bought my copy of Battletech last week, installed it and just then discovered that there is no ultrawide support at all. Unfortunately I bought the game on Amazon so I'm not able to get a refund. That's my mistake obviously, I should have done my research before getting it but at this point I thought that every major release (unless you're Blizzard) will work on ultrawides.
Almost immediately after discovering that I have sent an email to the support and asked them if they are working on fix. Only thing I got back from them is automated reply. I agree that's about time for status update on 21:9 support.
The sad part is the game is amazing and would be even more so with proper 21:9 aspet support to give us move visable area to work with.
A modern game without full support of of resolution and aspect ratio scaling as well as UI rescaling and FOV settings, just feels unfinished.
