I myself have random crashes while playing, and then once the game crashes during gameplay, it crashes on startup until I restart the computer. I have tried the various solutions suggested on this forum and none of them work for more than 20-30 minutes of play.
As a reference here are my specs:
i52500k@4.3GHz
8GB DDR3 GSKILL RAM@1600
Geforce GTX680
1000W Coolermaster Pro PSU
Windows 8 Pro 64-Bit
On every crash I get two messages. One says "Crysis 3" has stopped working" and the other says "DXGI ERROR DEVICE REMOVED"
Here are some things I have tried to solve this:
I have rolled back all my overclocks on both my CPU and my GPU
I have rolled back my drivers
I have lowered my settings
I have rebooted my computer(works temporary)
