Hey,
I bring to you a simple fps config for CS:S, which has many commands from this steam guide: https://steamcommunity.com/sharedfiles/filedetails/?id=1700892375

This config adds the following changes to his autoexec.cfg:
cl_ragdoll_physics_enable "0" // added, removes dead players from the ground
g_ragdoll_fadespeed "0" // added
g_ragdoll_lvfadespeed "0" // added
