Disappointed with the game’s base FOV of 70? Not a fan of post-processed anti-aliasing? Own a NASA Supercomputer/1966 Apollo Guidance Computer and think/don’t think this silly hero shooter stresses your computer enough? These three hidden settings could change your life!
Note: This setting is based on the May 2022 Steam Version.
So where are these settings?

Base FOV (70)
Modified FOV (100)
Deferred Anti-Aliasing
Internal Resolution
GstRender.ResolutionScale 1.50
GstRender.ResolutionScale 0.10
