aim_assist_script_disable 0
The mature reducing command in my comment works from my testing as it’s literally what the option in the settings does. You can also use this command to open the pop-up for it if you’re that sceptical:
openmenu mature_content_pc_disable_warning
The lack of smoothness is probably caused by you not updating your settings since the client now saves the settings to a different file for T5SP. Use this to move most of your settings to the new file:
exec conLZM.cfg; vid_restart
