Question ERR_GFX_D3D_INIT error crashes GTA V

[jujuLOL]

Hey guys,
since the new GTA V Casino Update my game does not start properly. It always show me "ERR_GFX_D3D_INIT". I tried to set my DirectX Version in the settings.xml to 10 and 11 but it not worked. I also reinstalled the game 4 times, but this doesnt helped too.
Maybe you guys can help me? I have an Nvidia GeForce GTX 970

Thanks
(Sorry for my bad english, im from germany lol haha)

Did you try setting the DirectX value to 0 and do you have the latest drivers? if so did you make sure to DDU your previous drivers?
