Find the autoexec.cfg file and open it with Notepad++ preferably which you can get for free here:https://notepad-plus-plus.org/
After that add the following commands:
r_maxmodeldecal 0
r_drawmodeldecals 0
r_PhysPropStaticLighting 0
gmod_mcore_test 1
cl_threaded_client_leaf_system 1
r_3dsky 0
r_queued_decals 1
r_queued_post_processing 1
r_queued_ropes 1
r_threaded_client_shadow_manager 1

r_threaded_renderables 1
r_fastzreject -1
cl_threaded_bone_setup 1
cl_threaded_client_leaf_system 1
snd_mix_async 1
