I have this same problem - I have an Ultra-Wide and it sucks not to be able to play it properly :( These screens are getting quite popular so I hope you'll consider at least allowing a console command to adjust FOV show-more :) Thank you very much for the product, donated!!
Horrgakx - you should check out the app "Flawless Widescreen" if you have this issue with other titles that don't have support.
