I am so happy to finally see 21:9 however it looks quite stretched, with your weapon taking up a lot of the screen even at max FoV i feel like i have tunnel vision i really hope that this is not working as intended gives me motion sickness.

We do not plan to increase the max FOV beyond 103, in any resolution. As a result, this doesn't leave us with a lot of options for 21:9 support. I know this is not the answer our 21:9 players want to hear. But we feel like it would be unfair to 16:10 and 16:9 players if 21:9 gave a substantial FOV advantage.

This post is considered to be relatively outdated with no developer follow-up response as 21:9 monitors have become more commonplace in the last three years. However there has been no new information since then.
