lol, it's not that bad
first thing I noticed was their misunderstanding of the differences between SSAA and downsampling
downsampling renders the game at whatever arbitrary resolution, and then scales it to the resolution of your display. this allows a lot of freedom in choosing a resolution that fits your performance needs. but it can be a problem if the game doesn't scale the UI well at high resolutions
SSAA (Super Sampling Anti Aliasing) is limited to integer multipliers (1x2, 2x2, 3x3, etc). for instance 1080p with 2x2 SSAA (2x horizontal and 2x vertical resolution. often just called "4x") is effectively 4k (3840x2160). this is gonna mean a rather large performance hit when using just a 2x multiplier. but it's applied like normal AA, so it doesn't effect UI elements
it's funny reading such a technically inept tech article. I guess it proves that anyone can build a PC
