OK so this is sort of an anti-VM question and I really should know the answer to this, but don't... I have a PC where I'd like to squeeze the most performance out of it possible, and normally I enable vt-d and vt-x in the BIOS whether I'm running VMware Workstation, VirtualBox or not. I leave it on in case I need it on most of my builds. In this case, this particular PC will not run any virtuals. Is there any detriment to leaving that feature on and not using it? Or is there an advantage to turning them off if you aren't using them?
