I tested on vmware win 8 and its works great, same as on my win7 laptop

i give 2gb ram, and grafic 3d on, then i disabled device (printer, soundcard, usb, cd/dvd) - always Virtualize Mode on ( you can set on in your bios ).. Disable too the sound for coc/bS you win so speed, u can too win speed with many disable drivers where you do not need...

try a fresh install windows on vmware, mostly helps
