Is there a command line to disable whatever feature causes this? PLEASE IT LOOKS AWFUL!!!
LE: Fix found by Maxwell_Adams user * I found the solution *
The new dark effect comes the new enhanced color grading. To disable the color grading, you have to use the command r_colorgrading = 0. Either punch it into the console manually or put in in an autoexec.cfg file.
Tried it and i can confirm it works. Many thanks
