I'll briefly describe the effect on both performance and graphical quality for each command. Also, if I reference a command that you do not have, simply write it in under the correct heading. Any of the lines in your ini that I don't reference can be left alone unless you desire to change them. It's worth noting that these tweaks are edited for my personal use on a high end system (specs below) targeting 60fps at 3840x2160p however, many tweaks will not affect performance at all.
