Thanks red, Feral Heart has worked fine even in 1 core processor due to /high command.
obviously the rest of all applications has freezed due to 1 core processor.
Runs very more stable, the rest of applications does not interfere when i'm playing.
I highly recommend this post also for 1 core processor, the only different thing is to remove the affinity command
C:\Windows\System32\cmd.exe /C START "FeralHeart" /d "C:\Feralheart" /high "C:\FeralHeart\FeralHeart.exe"
Processor:
Intel(R) Celeron(R) CPU 1.70GHz
