The same thing happened to me weeks ago. It does not happen to me with other games, not even with the return of NFS. It has been a while since BFV is giving my PC many serious problems. I will not play again until they are solved, I will not compromise the integrity of my PC. I have an i7 6700k without OC and the temperature increases to 70 ° C only with this game, apparently it consumes more cpu than gpu.
I have used stress tests like the Prime95 and the temperature does not rise to 50 ° C. The Unigine Overlay and the 3D Mark (all tests) do not generate bottlenecks or collisions, in fact they work very well and at normal temperatures. I have changed the thermal paste, I have tested the ventilation systems to rule out all kinds of cooling problems. And as for the GPU, I have a Strix 1080 A8G 11Gbps and it's cooler than a lettuce.
Now, considering that most of us have nVIDIA, the only thing I have left to eliminate the doubt is to go back to the old drivers to see if the problem is due to nVIDIA RTX updates, but I doubt a lot, since Una de what Lo What worries me most is the high temperature of the CPU.
