I’ve been playing for about two hours with no crashes so far. Below was the response from my ticket. Hopefully it fixes the issue.
1) Typically it’s a good idea to make sure we are working with a clean driver without any older files that can sometimes cause conflicts. Do a clean driver install by running DDU: Then install the latest driver
2) Next, change the Nvidia settings which has helped resolve some of these TDR errors for the new 2080 cards:
• Right click on the desktop and launch NVIDIA Control Panel → Manage 3D settings.
• Go to Program Settings tab.
• Select the game to change the graphics processor under “Select a program to customize”. If it’s not is not available, select the specific game from the drop down list.
• Select your “Prefer maximum performance” graphics card under “Power management”.
• Set Threaded optimization - off
• Set Triple buffering - off
• Set Vertical sync - off
• Set Maximum pre rendered frames - 3
- Reset the Overwatch settings to set everything back to default: Blizzard Support - Resetting In-Game Options
If this persists, it’s likely to be a hardware issue, so contacting Nvidia directly or a local PC tech would be the next best step.
