No worries, you can also disable it right now but yes you will need to edit the D3D8.ini file in \WOFF\WOFFScenery\Shaders
(make a back up copy of the old D3D8.ini first).
under section :
; Set to 0 to disable acceleration effects. HeadShake=1
set it to
HeadShake=0
Save as d3d8.ini
Note if you use notepad it will try to save it with .txt on the end of the file. That won't work. So in the Save as dialogue, choose Files of Type: pull down and change it to All files *.*
