First off, thank you very much for the kind words, you guys! But really, I’m a cheater and shop all of my screens fairly extensively to make it look dandy.
I’ve briefly covered a very similar question right here; so to sum it up, yes I do indeed use SweetFX and I highly recommend it for any GW2 players out there (considering it can really improve the game’s graphics without adding much more to GW2’s already CPU intensive nature).
I’ve also included a little comparison picture above that I’ve lazily slapped on together to basically illustrate just how much of a difference SweetFX can bring to your overall gaming experience.
You can grab SweetFX here, download/upload any presets here and if you wish to fiddle with your SweetFX settings you can grab the configurator here.
Regarding any tools of the trade, I use FRAPS to screenshot and record all of my gameplay (although I’m slowly veering towards OBS) and Photoshop CS6 to edit the goodies. If it isn’t entirely evident in my edits already, I’m a huge fan of the blur tool, and gradient overlays, just throw those on and there it is.
If anybody has any specific questions or you just want me to elaborate further on something, do drop an ask and I will try my very hardest to answer! \(^u ^ )
