About an Xbox One X patch fix the light, the shadow and every visual issues :
I repost the message of @HAMW05WC2014
because I have exactly the same problems. If other people have problems, say so. I would really like codmaster to bring a patch, because the first Dirt Rally is for me the best at the moment.
But he is now unplayable. They must do something!
"Hi all. I know the visual texture glitches are well documented in Dirt, Especially the multicoloured cockpit glitch and why Codemasters never fixed this very well known issue is still a mystery to me. Anyway at the end of the day if you usually quit the rally and restarted the glitch typically wouldn't bother you again for as long as your session lasted and given Dirt Rally is my favourite game I could live with that. But I recently upgraded to an Xbox one X having had the day one console since release and I reinstalled Dirt recently to find that on the X besides the known glitches there now appears to a lighting texture issue that effects stages in Sunlight. Turning fences and signs predominantly but including all roadside props and even sometimes patches on the road and the car itself bright green or yellow/orange in colour."
I don't understand why codmasters don't fix this because there are a lot of error reporting of the same kind. We bought the game, it must be usable and functional.
