Re: Persistent GPU induced freezing (PC)
The recent update ruined the game for many, i can't even play multiplayer because of "Error 1066" which is just being ignored with blanket fixes.
Back to the point however i am assuming it is solely this game, if so reinstall would be the first approach. My 1080ti has been running fine and averages around 48C in this game.
Make sure all your NVIDIA Settings are set to GPU not CPU. Update your drivers if you have not already, not just GPU but everything else as well. Check task manager just for broad readings on what is maxing out when these errors happen.
You can do digging with through DxDiag and crash logs yourself, it takes awhile but just a lot of reading. Support might take awhile to respond. When i hear system lock up and audio bugs i think RAM/CPU over GPU but you seem convinced it is GPU.
Also if you have not already try running in windows 7 compatibility mode.
Side note: Consider what programs are running in the background and make sure they are not conflicting with BF2.
