Having done a lot of testing myself, this is just my perspective. My guess is that it's either AI or a copy paste from another servers' forums. You include old commands that are non functional in the config and launch options that are nonsense. There is no way you actually believe that -nohltv or -nojoy is gonna do anything for "stutters" or crashes. 90% of issues people have are hardware or content related. Sure there are some cvars that can mess with your game if you change them, but that's if you change them. Overall, it seems like you don't know your stuff and it's not smart to guide people that way. Guides like these incentivize people to dabble in stuff they shouldn't. It was understandable years ago when everyone had shite pcs and would do anything for that +3fps but nowadays it's completely unnecessary to touch this stuff. Get a job, buy a better pc and you'll never complain about stutters or lag unless it's the servers fault
I understand that your goal in the end is to help but that's just the way it is...
