I also had issues with it, not so much for the fixed camera FOV, but because the weird momentum/camera mechanics (it always felt like it was pulling and shifting in non-linear ways I couldn't control) made me feel motion sick within a half hour of getting in game. Googling at that time, it seemed like a common enough issue that people had hacks or add-ons or workarounds to address it, but I ended up just returning it for a refund as I had less than the steam hours limit.
