# This is nginx setup of sneakyjoe.ru
# Based on obs forums and helping squad articles.
# Made for personal use and sharing with the crowd.
# Updated with new tweaks for the best job each time I learn something new.

# WARNING! Streaming WILL drop all the fucking time if you stream to server higher than 1920x1080/60

# WARNING! This will 100% work only on UBUNTU 16.04 with HWE Kernel enabled on installation.
