Same issue, already had to use the fixed EXE to get the game to work on more that 4 cores.
Ryzen 5 1600
16Gb DDR4 Ram
more than 200GB left on HDD
Radeon RX 560 4Gb
Windwos 10 64 Bit
We need a fix for this. As with the way it runs now, there is and has been major issues with this game that you have not attempted to patch or even address.
This is most probably a Windows and not a game issue.
Because of the missing official documentation I can't say if this workaround will still work on Windows 10.
