Well, happened again. I get the following error message:
DirectX function "GetDeviceRemovedReason" failed with DXGI_ERROR_DEVICE_HUNG ("The application´s device failed due to badly formed commands sent by the application. This is an design-time issue that shoud be investigated and fixed"). GPU: "NVIDIA GeForce GTX 780", Driver: 34788
This error used to happen before and it was related to Origin overlay provoking a dead lock with the driver or something like that, disabling it should fix the issue. To do so right click on the game in Origin and click in "game properties" and there check the box "disable origin overlay" (or something like that).
Also I've experience several crashes and glitches after installing JoH and the new version of Origin. The first problem was after saving a game with JoH, I loaded it and I started to see odd polygons everywhere, but only with savegames after JoH started. Fortunately I managed to fix it just by restarting the PC. The second problem was after installing the new Origin update, DAI crashed everytime I try to start it, then again fixed it by restarting the PC.
Hope that helps.
