Far Cry 3 is out, and for those of you on the PC, that means being able to mod the game to an extent that's well beyond the capabilities of any console version of the game. Part of the benefits of having the PC version of Far Cry 3—besides being able to play it on Steam—is having the ability to alter some of the game's hidden settings and tweak it to your liking.
Among one of the things you can do with this much access is to be able to shut off Far Cry 3's heads-up display (HUD) for a much more immersive experience, sans pop-ups, health status and ammo count. It's not as if you can't track your health by looking at the blood bars around your view when you're injured, in any case. Doing so will make the game much more like its predecessor, Far Cry 2, which lacked any sort of HUD and instead used diegetic elements.
To do so, you'll need a HEX editor of some sort and edit the following files, and change a few details. This little guide below was put together by GaulKareth on Reddit.
DX9/10: Locate and backup \bin\FC3.DLL, then open the original file with a HEX editor, I’m using Hex Workshop.
DX11: Locate and backup \bin\FC3_d3d11.dll, then open the original file with HEX editor.
Search for "showuielement". In the next few lines you will see S.h.o.w.U.I.E.l.e.m.e.n.t.
Replace the S.h.o.w.U.I.E.l.e.m.e.n.t. with H.i.d.e.U.I.E.l.e.m.e.n.t.
To remove all intrusive sounds:
Copy and paste each sound item from the list below into your HEX editor and search for TEXT, then replace the HEX value for the text with zeros.
