sv_maxunlag

[Intensity]

what is better

sv_maxunlag 1 (default)

or

sv_maxunlag 0.5 (got this from a league server config)

[Drocona]

Depends on what you prefer.

maxunlag 1 makes the game smooth but it will decrease hit registration (due to prediction).
maxunlag 0.5 will make the game more stuttery if it's sensitive for that, but will increase hit registration (reason why it's used in leagues)
