Hello, having the same problems as you, I decided to conduct some research and labs .... For example, I have an FX-6300 CPU, 3.5GHZ Stock ...
You talked about the game is not mult threads, however, to put the game on only 1 core processor, my fps was stable at 35 .. which is very bad, and the use of this core get selected in 100% .... then did another test, I set the game to 2 cores, my fps was at 60 (with sudden drops as everyone is reporting), and use these 2 cores was 70% on each core ... for 3 or more core not made a difference .... that is, the used game 2 cores.. ll realializar some more tests like overclocking etc. and I will post! Thank you all!
sorry my bad english... bad google translate...
