If you don't know then you don't need it

Virtualisation is a technology that 99% of people have no need for.

I'll leave it off and i do know what it is just not if games would ever need it. It has always been on by default on my other PC's. If only virtual machines, running another OS on top of the main one for testing stuff and other things like that need it. Then i have no issue simply leaving it off, like i said the PC seems to be running perfectly had it over 3 weeks now.

All i need now is a gtx1080 and I'll have one hell of a gaming PC (currently it has a 4gb asus gtx960) Which surprised me to be honest. Maybe it's because i have not upgraded graphics cards in any of my PC's in ages. But i was surprised when it did 70=88fps+ at 4k everything on high 4x aa and af enabled on portal 2! That is quite a hardcore game for it's time and it's playing it in 4k.
Modern games of coarse kill it in 4k and i have to drop to 1080p then there ok.

Never say never, but certainly no games in the foreseeable future would require virtualization. It's an interesting concept, though.

I am pretty sure you do not know what virtulisation does, People do not seem to be telling you. What it is for is so you can run another Os on top of windows, so if you want to say run Linux you can and still have Windows running at the same time, or you could say have windows 8 running on your computer, but windows 10 as a virtual machine.

Very useful if you want to look at another operating system, but not install it on your machine.

Which is pretty much what i said yesterday. I once used it once to run ubuntu ontop of xp probably before cpu vitalization existed or it was in it's early phases not sure on a Phenom 2.
I basically said what you just said yesterday here.

" It has always been on by default on my other PC's. If only virtual machines, running another OS on top of the main one for testing stuff and other things like that need it. Then i have no issue simply leaving it off,"

I wanted to know if it would cause any issues off for anything other than virtual machines.

No. It won't cause any other issues.

Thanks guys for all the quick very informative information. I now know a lot more about virtualization. I new it was use to run a OS in a virtual machine etc on top of your own. And that virtualization speeds it up. Just was not sure if games etc would ever need it. I will leave it off for that gaming PC.
You get faster information on here than you do on computer help sites.

Mine is always enabled in the bios and it have not given me any problems, I think the reason it can be disabled is for security top stop people running a virtual OS.

Disabling hardware virtualisation features doesn't prevent running virtual machines - there are virtualisers that work with no hardware virtualisation features whatsoever, though the performance is not very good.

I believe the main reason why hardware virtualisation features can be turned off is if they are discovered to have an operational and/or security flaw. I have an old and still marginally useful Core 2 Duo laptop with defective VT-d - it interferes with the graphics controller. This is a chipset erratum that required disabling VT-d in the BIOS to resolve.
