Generally shorthand for animation, sound, and somewhat game balance. As for what’s good about it I couldn’t tell you because I came into the game jaded. IMO the visual design is nothing standout and the aim assist on mouse aim makes the entire experience sleep inducing.
That’s not a bad build, really. Although I can’t imagine the air cooler will be necessary for a 4500, much rather use the stock and possibly upgrade to 32gb RAM if in budget. My stock 2000 series Wraith cooler has done me well in 40c summers.
