Hi, I'm still using PD9, since the OS X 10.10 Yosemite Beta 2 Upgrade, my Win8.1 VM is using the discrete graphics, as soon as I power them on. There ore no configuration changes been made on PD9 or the VM. Before the OS X Update the VM is running with the internal one. longer battery life is configured 3D Acceleration: disabled graphics memory: 32MB any advice how the get to the old behaviour!?
