After gathering feedback from the community, and discussing things internally, we have made the decision to no longer allow Re-Shade to be used in game.
This was something the team discussed at length last night and we feel this is the best move as it gives an unfair advantage when removing/changing fog.
This drastically changes the competitive dynamic of the game by allowing players to reduce the fog visibility by using the 3rd party software. If you have previously used the software, EAC will request that you remove it before you are allowed to connect to the servers.
We appreciate your feedback and look forward to bringing our next hotfix very soon.
