you're on 32 bit windows? what are your specs?
Processor: intel(R) core(TM) i5 CPU 650 @ 3.2.0GHz 3.33GHz
RAM: 4GB
graphics card is the most important
intel hd graphics
But I think it's because unreal engine 4 isn't supported by 32 bits devices :/
i doubt you'll be able to keep a decent framerate with only intel HD graphics.
unreal can support 32 bit, although i compiled it for 64 bits.
