You may need all these actually:
cl_threaded_bone_setup 1
cl_threaded_client_leaf_system 1
r_threaded_client_shadow_manager 1
r_threaded_particles 1
r_threaded_renderables 1
host_thread_mode 1
mat_queue_mode 2
Also for those on quad, add -thread 4 to the command line as it's limited to 3 otherwise.
Does this speed up the game at all adding more FPS?
