If you search the cloud profiles there is a Mordhau Geometry 3D profile by [High Fov] that works great!
Make sure to turn in-game fov to max settings in game settings, fps in game to 90 in the menu, turn off temporall AA, motion blur, head bobbing, put graphics to medium.
The only issue is if you run and stab (shift and scoll mouse wheel) that is a hotkey for vorpx zoom. I would recommend changing your sprint key to capslock to avoid that. It’s very immersive, and I’ve had no issues playing hours on servers!! Have fun.
