![]() My guess: It’s off by default because hardware-assisted virtualization incurs very high CPU loads, which in turn requires a lot more power than normal operation. Why is virtualization disabled by default? A virtual machine allows running a different OS than what is installed on the computer by using some kind of virtualization software like Virtualbox as an example. CPU virtualization allows a computer to run a virtual machine. It has absolutely no effect on gaming performance or regular program performance. ![]() … Instead, it causes the second virtual CPU to use physical resources that other virtual machines could otherwise use. For applications that are not CPU-bound, CPU virtualization likely translates into an increase in CPU use. If you have no virtualization software running, your system will never use those instructions and there is no performance degradation.ĭoes virtualization technology affect performance?ĬPU virtualization overhead usually translates into a reduction in overall performance. Does enabling virtualization reduce performance?Įnabling virtualization in the BIOS just means that the processor is capable of using those instructions. In rare cases (you are a high profile person and will get targeted attacks and in particular rootkits) it’s safer to keep it off. In most cases enabling virtualization is fine. This feature is also a requirement for many virtual machine software and is required to be enabled in order for them to run properly or even at all. This allows an operating system to more effectively & efficiently utilize the CPU power in the computer so that it runs faster. Can Windows 10 run Hyper-V?
