You're probably aware that R3E doesn't offer the usual FOV setting in degrees, but instead opts for setting FOV via a cryptic multiplier number. Thankfully, it has been recently explained on S3 forum in one of the posts what the number actually means: It is a multiplier of the default FOV value of 58 degrees (vertical FOV). So for your convenience, here's a conversion table of all possible in-game FOV values. 1.3x - 75.4 degrees 1.2x - 69.6 degrees 1.1x - 63.8 degrees 1.0x - 58 degrees 0.9x - 52.2 degrees 0.8x - 46.4 degrees 0.7x - 40.6 degrees 0.6x - 34.8 degrees 0.5x - 29 degrees Apparently, according to the post, it's also possible to set a specific FOV value not available through the setting, but it has to be done by editing the game files (as explained there). Thought people might find this useful and worth sharing.
