From 075833e39368e63e06889f21140f816420e83541 Mon Sep 17 00:00:00 2001 From: Lars Hofhansl Date: Sat, 3 Dec 2016 21:43:25 -0800 Subject: [PATCH] Fog: Make fraction of visible distance at which fog starts configurable Optimise the fetching of global settings 'camera_smoothing', 'cinematic' and 'cinematic_camera_smoothing'.
