Only 4 variables -I don't see how this could bloat your savegame or cause any kind of CTD.

It does use scripts, but the scripts are tiny and only fire during the knockback moment. Sort this to the bottom of your load order since it modifies the attack data of vanilla races, which means that if you're still using Racial Body Morphs you should probably upgrade to FK's Diverse Racial Skeletons instead, which uses a more modern skeleton, and then use the patch for this mod in the optional files section. I prefer knockbackViaRace.zip because it makes NPCs knock you back too, which evens the playing field a lot.

Or you can pick the old knockback.zip version in the miscellaneous files, which works with any mod race but may conflict with some perk overhaul mods and lacks all the new features. You can pick the new knockbackViaRace.zip version, the main file, which is compatible with everything except mod races (although there are patches for the Half-Dragon, Dagi-Raht, and Ohmes-Raht races already).
