I use this preset, although I modified it slightly to fit my tastes more.
EGVA SuperNOVA B2 750W | 16 GB DDR3 1600 | Acer XG270HU | Win 10×64
MX Brown Quickfire XT | Commander Shaussman [AGNY]- Fort Aspenwood
I tried using several presets and custom ones, the different areas/locations already have drastically different colour pallets to match the overall mood adding a general preset over the top of that ruins it, nothing I did made the game look better only worse. I use sweetfx on tons of other games but with Gw2 I stick to vanilla.
Even without changing colors/saturation/etc you can use sweetfx to get rid of the blurriness of the vanilla game, which is incredibly nice

That’s the only use of it that I endorse. Most of them are awful, the one you linked literally changes the time of day. Turning storm clouds into a clear day.
