Client crashing randomly

Technical Support

My game client keeps crashing to desktop every few minutes (even seconds). This issue started occurring with the most recent patch.

Event viewer contains two errors for the crash:

Looks like the crash may be due to the latest Nvidia drivers (445.75). Nvidia released a hotfix driver to address an issue that may cause crashes in DirectX 11 games. Try downloading and installing the 445.78 hotfix here:

If that doesn’t help go ahead and post your DXDIAG and the latest crash log so we can take a look.
