sv_turbophysics
From Valve Developer Community
This boolean ConVar enables/disables turbophysics on the server. It's only on by default in DOD:S.
When sv_turbophysics is non-zero, players can't move physics objects by touch. To move them in turbophysics mode, they must press the use key. This prevents collisions and as a result less CPU-power but physics behaviour will be less realistic.
Note:Command parameters are described inside the < and > characters.Syntax: sv_turbophysics <boolean>
