Read this about the FPS issues . There is little point for anything other than very basic optimization at this stage . As long as the game runs , and it does , then the Alpha is in a functional state . We can test for issues , we can report issues , we can experience a fraction of what the game promises to be . They are currently still implementing and iterating on features , so it will be a while before they buckle down and optimize the crap out of it . It ' s in a true Alpha state . A term that is muddied by other developers trying to excuse their shitty development practices . Instead of saying we messed up , we are actually in beta , but it ' s in a terrible state , they say it ' s ALPHA ! SC is still very much in development , with the lions share of basic features still to be implemented .
