Arusai,

Can you post your D3Debug.txt file? It's located in the main Diablo III game folder.

Arunas,

I'd suggest trying with Vsync enabled and in a windowed mode first, changing the settings later if they allow you into the game. If that doesn't help, I'd revert to an older Nvidia driver next, 353.62.

To change the settings I mentioned, you'll need to edit your D3Prefs.txt file which is located in your My Documents\Diablo III folder.

You would change these lines

DisplayModeWindowMode "0"
Vsync "0"

to these

DisplayModeWindowMode "1"
Vsync "1"

Arusai,

Opening Fullscreen Direct3D at 1600x900, 32 bit, 50 Hz.


This is likely the problem.

Try editing your D3Prefs.txt file which is in your My Documents\Diablo III folder. Look for and change this line:

DisplayModeRefreshRate "50"

to

DisplayModeRefreshRate "60"
