Nowadays, I turn off all shadows and reflections, and depending on the game, I turn off post processing and ambient occlusion as well. These options make screenshots look GORGEOUS, but in motion? I don't really notice unless I stop and just take in the scenery, which I don't often do in a game nowadays. However, I almost always turn on V-Sync and and Triple Buffering. Makes the game so much smoother.
For a game, I turned off shadows and it looked BETTER, and my FPS went from 30 to 60.
