Is there any performance difference if I turn on intel graphics or not?

I want to have max performance and overclocking, and at the same time be able to use quick sync.

I know I'll have less ram to play with but what about cpu performance?

If anything you'll likely have less performance on the CPU if you turn on the integrated graphics. I always thought that those integrated graphics on the cpu were good for home theater PC's and such.

after reading about it closely, looks like the cpu has a dedicated gfx engine built in, so enabling gfx doesn't affect overclockability or straight up bench performance.

Just for lulz I went ahead and enabled the HD3000 in the BIOS and besides havin' 64megs of ram less (whoop-dee-doo) I can't see any difference in the benchmarks..

You can adjust the amount of ram for the on board video via bios. I think max is around 480mb.
After seeing benchmarks, with it enabled you do lose a couple fps.

With BC2 and max memory and the on board only, i think i got 6-7 fps @1680x1050.

You don't lose FPS, it depends on what mode you're running it in.

Running Virtu in "i" mode means you've set intel HD as your primary gfx adapter in the BIOS. It gives you energy savings but performance is terrible.

The "d" mode will work only when you've enabled intel HD in the BIOS but you're still using discrete graphics as your primary adapter and don't have monitor connected to on-board gfx.

This allows you to use SLi/Crossfire and etc while being able to encode videos using quicksync. That's what I am running and I've benched to see if there is any fps loss, there is none.

thats awesome, which board are you using sovietdoc

You can either be part of the problem or be part of the solution.

with the Z-68 platform and Virtu Lucid, arent you supposed to be able to run both the onboard and discreate card at the same time? Where your monitor is connected to the onboard using the gpu on the cpu for normal stuff, i.e. word, IE, solitare...... and then when you kick in a game like BFBC2 or the likes, the discreate gpu takes over.... Yeah ?????

Okay I had it setup wrong at first. Thanks to the awesome LACK of good guides.

First, I had intel VGA as my primary device in the BIOS. I hooked up my monitor to both intel chip, and one of the 470s. After enabling Virtu, games ran at 10 fps, screen always would flicker and my custom color profile would always get reset to intel stock.

Only later on I found out that was the "i" mode that's supposed to save power.

So the heck with that.


Setting PCIE 16x as primary adapter in the BIOS and pulling HDMI out of on-board VGA made Virtu run in "d" mode. So game fps is back to max, no flickering, no color issues. And that is how it's supposed to be running.

Only downside is I did all that to use quickSync in Power Director, but it doesn't work with Virtu. It just crashes :(
