My original SS Is running in 4: 3 , but rather was in 16: 9 as SSS . Does anyone know how do I go back to 16: 9.

Go here http://pcgamingwiki.com/wiki/Silent_Storm
Half way down the page are video instructions, http://www.wsgf.org/f/u/contrib/dr/257/hacks/universalreschanger2.zip Extract to game folder silent storm and then change res.ini to what you want. for me I am on a lap top with 1366x768, so changed the ini and saved it. Works great but some large text are clipped very slightly but not enough to spoil game.
