Ok, I've been asked a few times recently what filter I'm using in my screenshots and it's my own custom made settings. A am happy to share but won't be updating it for the masses and flooding it with updates. This is it. If you like it, use it. If you don't then don't. Set saturation to 85% in game.
RT: stands for realtone (photo realistic)
HD: High definition.
FX: Photo FX but very subtle.
This filter emulates you looking through a visor or windscreen with it's colour tone choices. Back up your weather files as this overwrites. It includes custom clouds and sweetFX efx light settings for no FPS loss. This has been updated and fully working for AC v1.7
