About This File
I did this because i don't like how the weapons swing/waggle in first person view, in Jedi Knight: Mysteries of the Sith, being worse if you use jkgfxmod. They are very distracting in the action.
It happens too with Jedi Knight: Dark Forces II, but it's not as noticiable as with MotS.
I only edited the <game>/Resource/cog/*.cog files, changing the "jkSetWaggle" parameters to a half of the original files, taking the EMSITH or MotS Neural Upscale Special Effect Annex 1.0 cog files as reference.
Extract the file in Mysteries of the Sith's game folder. If you have a (mostly) vanilla game it shouldn't overwrite any file.
If you are using other mods and there are file overwrited, it could cause issues, but i don't know because it's untested.
