In NWN, simply go to options and disable "shiny water", and that should hopefully fix any random crashes you might get like I was getting.
In Farcry, go to start menu and under Farcry (probably under Ubisoft), bring up the Farcry configuration tool. Go to advanced video options and select custom. Scroll all the way over to the right and select water effects. Under water effects, select "WaterUpdateFilter" Double-click in the value cateory with "WUF" selected and change it to "0.001". As a further precaution, put water effects to "low" before doing this to make sure as many water effects are disabled as possible. Prior to doing this, whenever I tried to start the game, it would always crash back to the desktop during the loading screen. After I altered the "WUF", I was able to play! Now I just have to hope the v1.4 patch I'm downloading will allow my mousie to work .
EDIT: To get the mouse to work, you probably altered what mouse button does what. To fix it, hit default so the original keys will go back, and you can edit every other key except the mouse buttons and wheel.
Any other games, do your best to disable all water effects, and hopefully it will solve your problem .
