Can you flick between IGP and proper GPU on the fly?

[mark2410]

i can see a propper new build coming soon and im trying to work out what i want. i think im going to want a reasonable gpu but i realise most of the time it wont be needed so i like low power too. my my laptop will let me flick between the intel igp and the radeon.

what options are there for similar in desktops? i think amd ones let you by allowing a proper card to run as a crossfire, is that the case? also can you do the same with intel and nvidia?

I believe this is what Lucid Virtu does on the Intel side of things, you need a supported chipset/motherboard.

Yes lucid virtu does do this, but its poor and pretty damn useless (Plus doesn't save any power as your GPU wont turn off) Frankly I wish I Didn't install Lucid, I'm too chicken to uninstall it in case something goes wrong so I just leave it off

Indeed, lucid virtu allows this. And you can run the igpu and an add in card simultaneously. However when i last tried it it was quite buggy on my old Z77 system.

i thought all the lucid vertu did was allow quick sync and stuff when running a proper gpu. i know it was briefly all the talk but id seen notehing about it in a couple of years and even their web site talks about old z68 era motherboards, so two generations ago stuff.
