Edit the following into the controls section of fallout_default.ini:
fForegroundMouseAccelBase=0
fForegroundMouseAccelTop=0
fForegroundMouseBase=0
fForegroundMouseMult=0"
This isn't working for me. I tried this after the patch and no go. Also these options weren't there to begin with, i had to add them (which is what i think they were implying?). Anybody else find this didn't work for them?
