reduce your screen resolution to increase performance (not entirely, but to get optimal performance)

Tactics for recording : -if you are on Windows 10 : use Windows recorder Alt + G (best option in my opinion)

-you can use OBS for streaming if you want but be carefull, if you play on HD Edition and if your pc is bad, this can ruin your runs and the time is not in game (x2) but RTA (reduce the bitrate of your stream or non-stream if the lag appears in the level)

If you play individual campaign - full campaign use SSD hard drive for reducing load time
