For users of the Killmove Control mod, these variables will be familiar. All I've done is collect the relevant variables by using the saveini console command.

[VATS]fVATSCastingAfterKillDelay=1.2000uVATSRangedPercentSneak=33uVATSRangedPercentGlobal=33bVATSIgnoreProjectileTest=0bVATSAllowNoKill=0bVATSMultipleCombatants=0bVATSForceRanged=1

As you can see, despite claims that Skyrim uses an entirely new engine, these variables are referred to as VATS (Fallout3 for those that are not familiar). Most of the variables are pretty self-explanatory. To turn off the killcams, change the Percent variables to 0.

• bVATSAllowNoKill will allow killcams to play even if the target is not killed. This seems to occur sometimes regardless of setting.
  
• bVATSMultipleCombatants enables or removes the requirement of there only being one combatant.
  
• bVATSForceRanged may need to be set to 0 along with the Percentage values if you want to disable ranged killcams.

I have not tested these variables extensively; I only collected them here so people could add them to their Skyrim.ini file and test them without having to use the saveini command and root through the file that is created. If people observe different behavior associated with these variables, I will edit the list to be as explanatory as possible.
