Does enabling hardware x86 virtualization (AMD-V or Intel VT-x) slow down my computer?
Obviously, it improves the performance if I'm running virtual machines, but what if I'm not running any VMs?

No it will not. Most of the recent processors are coming with VT facility and its enabled by default.
Note that I've read that turning on this feature can slow normal operations down by 10-12%, which is why it's normally turned off.
This is a myth.
