Crashing with no error message solved

I have a good rig and could run on Ultra settings just fine however I was crashing before even completing a game. I wasn't aware that there were crash logs until I surfed reddit for awhile. They get put in your documents folder.

I checked my crash logs and saw that there is an exception code given (I used Visual Studio); mine was 0x887a0006. I googled that and it came back that my GPU "DXGI_ERROR_DEVICE_HUNG" which seemed like it meant that my GPU was freezing up or not receiving instruction. I combined this with other details from the dump file that showed modules the game was using that I guess are a problem. (I used previous debugging experience and treated these modules like a call stack. I don't know if that was correct or not but whatever)

The first module that was not the executable was "GFSDK_ShadowLib_DX11.win64.dll". I figured that had to do with shadows so I fooled around with my shadows settings in game. I found one that was past Ultra that has seemed to work for me. I set my shadows to "HFTS". I don't know what that is but it has worked for me and so far I have been able to play several games in a row without crashing.

TLDR You can try changing your shadow settings to "HFTS" and that might solve crashing for you. Also, error logs are dumped in your documents folder.
