^^ Hi RCaloca yes I am using version 4.5 offcourse my PC is below requirements as I have a dual core Pentium G 3220 haswell CPU. Which may be the culprit I suspect.
I want to maybe get a core 3.6GHZ intel core i3 which acts as a quad core. The i5 are so expensive!! I am a student and thus am not rich 
but I thinks I can manage with the pentium G sure some games take 3 hours to cook but it can be done. I hope during the project and design of the game this CPU does not become a major problem.
I have a 128GB SSD and 4GB RAM DDR3 but I have a old stick of 2GB lying around maybe I should put that in the PC
thanks for the advice jwatte
