Is there a widely used or recommended mouse sensitivity to use or is it all just down to personal preference?

use what you want

lower is generally better, otherwise go crazy

just do what feels comfortable, just as long as it not too slow, other wise you cant turn around quickly for some tricks

Ight ok thanks

Another quick question: Are Znernicus's tutorials still the best to use or are there any more recent updated ones because even the "Updates" video in that series is something like 3 years old now

Znernicus tutorials are generally pretty good for starters, except for Chapter 8 i believe. Optimizations/new strats are spread out through the game compared to Znernicus' tutorials, but even then you can get pretty respectable times with the strats on the tutorials. Over time, if you get invested into the game, you slowly pick up better strats.

Watching the top runs is always recommended anyway

it depends on ur dpi. if u have a high dpi, lower sensitivity would be better, however if u have low dpi, higher sensitivity would usually work

Protip: Threads from a year old are not relevant anymore ;) @Soulfur

got it
