TDR, also knows as Timeout Deteection and recovery gives your Graphics card 2 seconds to react before it resets the driver.
Nvidia has yet to push out a fix for this, and it also happens on ATI sometimes.
The only workaround is editing/creating up to 3 registry files
Some reasons for it are:
I managed to get rid of it while playing STo, but still have it in games like King Arthur II, to an extend that I can't finish a battle, so don't worry guys you are not alone with this.
- Edititng/creating the registry files
- Always update your driver (even using beta drivers) until its fixed
- Don't use Aero-Desktop envirionment (does at least help with STO)
