Truly a great proper pc game, and majority of pc users still loathed ubisoft with their horrible DRM crap, anyway apart from this warfighter is an absolute gem...the graphics can looks stunning with a sort of yellowie impressions, gun firing's sound is quite good too and also it's best to use K/M since there is no game pad for this but you'll love this tactical FPS shooter alright . the mouse's binding is a bit lame and it dosen't set to how you want it done especially for cross-com..however it's still a decent pc port rather than a crappy console's port unlike today many games for pc are poorly done...
if you're still keen to get this to work using the mouse properly (middle wheel),: go to steam folder>steamapps>common then see GRAW folder >setting folder> and see "ctrl_set_def.xml" file and profiles folder & see "profile.xml" file then change to notepad ending with .txt instead of .xml to open up then add the missing binding (see below) and return to .xml when you've finished.!
like this :
you need to add the missing binding for the middle mouse wheel :
<button id="hud_use/action" binding="3" device="mouse" group="misc"/>
avoid the screen loading freezes-dont use full screen mode
