After a huge amount of frustration I have found a way of playing on dx9 without causing the screen to crash and go black. I have established that the error is caused by turning off settings iin the clipboard , specifically graphic settings. as soon as I alter one and hit save, the screen goes black and requires a full reinstall of the game.....its taken 14 reinstalls to establish this.
the fault is there in the settings somewhere but and it wasn`t there prior to the updates.
so, I altered the settings on a black screen and hopefully got them how I want them. I then uninstalled and reinstalled the game and as long as I don't touch those graphic settings it will play.
there graphics card is perfectly capable of playing this game as I have tried it on other higher spec games and it works fine the issue is somewhere in the build , a change in the clipboard graphics settings that is causing this. perhaps you guys could look at that specific area and see what has changed.
running it on dx11 is hopeless as it finds issues in the terrain and just throws up constant messages of errors. My computer has dx12 so it should have been fine.
at least I have something, but the frustration is very evident in my postings.
