I was having this problem on my RTX 2080Ti Founder’s edition and after a number of chats with blizzard tech support, they tokd me this is a TDR issue, which means the error is thrown by windows because the GPU stopped responding for a fraction of a second. they advised me to contact Nvidia.
I contacted Nvidia. They asked me to do the following and contact them if the issue still persists. here is what they’ve asked me to do :
Open NVIDIA control Panel (Right click on desktop and click on NVIDIA control panel) > Go to Manage 3D settings, under 3D Settings > select Program Settings > Select app/game from the dropdown menu > if it is not listed in the dropdown menu then click Add then select the respective .exe to the list (I was having problems with my Overwatch, so I selected Overwatch from the list) > And now change these settings from Option 2.
- Power management mode - prefer maximum performance
- Tripple buffering - Off
- Threaded optimization - ON
- vertical Sync - off
Apply these settings, refresh the Desktop several times, start the game play and check the performance
I have played for an hour after making these changes and have not had a problem since. Will post an update if I encounter the problem again.
Hope this helps anyone facing similar issue.
