DirectX nonesense - Direct 3D Initialization Error

[snowhiker]

I've started to get a "Direct 3D Initialization Error" after starting a game. Game requires DirectX 9. I have DirectX 9 and 11 installed.

I have updated video drivers and re-installed DriectX v 9 and 11. The game I was playing worked fine at 3840 x 2160 x 60 Hz for a day or two, now it errors out. Can't think of anything that I changed after successful game launches at "4k" resolution. I went into the game config file and changed launch res to 1920 x 1080. Same error. DxDiag finds no errors, 32 & 64-bit tested.

Any suggestions on how to proceed?

Did your driver update automatically? I have had MS Update override 3rd party drivers with older ones.

Does that apply to all games or is it only an issue for one title?

For me restarting the whole machine always fixes such issues. I have them all the time, sometimes an older DX9 game like Asheron's Call or Oblivion craps out and then I can't start it back up without a restart.

tl;dr
I'm working A-OK now. Thanks again for the quick responses.

Long version.
DD, I never update video drives using windows update.

Merc, it was one game.

Sed, I powered off and restarted several times. And re-installed video driver and Directx 9 and 11.

I upgraded my video driver in 2013 and hadn't touch it since. I upgraded to the latest 365.xx Nvidia driver when I got my new UHD monitor and the game loaded a few times then just crapped out. I just now upgraded to the new 368.xx driver that can out May 23 and that fixed my issue. I knew there was a reason I never update my video driver unless I have to.

Funny, it's usually AMD I associate with breaking games with driver updates.
