These are actually game based tips, not upgrading hardware or drivers, etc. Some nice ones.
One they missed was jumping and dodging at the same time (you HAVE to bind dodge in order to do this) provides a longer dodge that evades damage just a touch longer. It's hard to master (I can do it about 50% of the time so far), but very useful.
