In Game Settings are Maxed Out @ 1080p with 4X MSAA. To Disable HUD, make sure Developer Console is Enabled in the Options Menu and then type "cg_drawhud 0". This will turn off the HUD while in Single Player Campaign, this is only temporary and will not stay persistent unless you manually edit the "config.cfg" file. This cfg file is stored in a hidden folder so you must Enable "Show Hidden Files And Folders Option" in Windows to see it. Provided you have done that the cfg file is found at C:/Users/(YourName)/AppData/Local/Activision/CoDWaW/Players/Profiles/(Your Player Name)config.cfg. You will need to open it with a program like Notepad ++ to get proper formatting and then you need to manually edit the Value from 1 to a 0 for Off. Note this will disable all prompts and Sniper Scope and other crosshair and aiming reticules so use only for screenshots or if you like a more realistic game experience.
