Hello, this isn't a huge find, and it isn't gonna make an extreme difference, although this may help you!
What this is, is when you walk/run your weapon sways back and forth and this will lower it to the point where it doesn't move at all when you walk/run (this doesn't mean you can shoot when you run).
Step 1: Go to CombatArms Folder
Step 2: Click Profiles Folder
Step 3: Click player.txt
Step 4: Control+F to bring up find and type weaponsway and hit enter
Step 5: Change the 10 to a 0
Step 6: Save the text file by doing file, save
Step 7: Play the game with no weapon sway!!!
