What is lucidlogix

Installing Virtu was very simple. Just go through the installer application, reboot and you're good to go. The only requirements are that you're using a compatible video card and that your display is connected to the SNB video out and not the discrete GPU.

Other than the irate control panels, the rest of the experience was completely seamless. I ran games, browsed the web and even transcoded a video - each application behaved as if the only GPU available was the one best suited for the task. Quick Sync even came up as an option under Arcsoft's Media Converter 7.

I measured performance with Virtu and natively off of the dGPU itself in four games to see how much overhead the frame buffer copying and Virtu interception posed:. Given the relatively consistent performance everywhere else, I'm guessing this is an early-software-artifact rather than a normal occurrence. I also ran a Quick Sync test both with and without a discrete GPU attached - performance remained unchanged:.

Finally I decided to run a Quick Sync test while I ran our Metro benchmark to see how running two tasks, each on an independent GPU, impacted each other:. While Metro didn't lose much performance, the Quick Sync task ran considerably slower. Here we see that there are still some kinks that need to be worked out. Note that even in this case there's a power penalty over a purely integrated setup - the dGPU is still active to a certain extent.

Intel is slowly correcting the issues with the Sandy Bridge platform situation. The first B3 stepping 6-series chipsets are now in the hands of OEMs and motherboard manufacturers and Z68 boards are coming in the next quarter. Lucid's Virtu is a key part of the strategy however, at least on the desktop. In mobile it's a non-issue as everyone supports some form of switchable graphics there, but for desktops we need a universal solution. While the Virtu release candidate still needs some work, it's far more polished than I expected it to be.

Once setup there's no user intervention necessary - the software just works. Fire up a game and it'll run on your discrete GPU. Board makers and OEMs should have their hands on the RC of Virtu now, meaning we should see it show up in motherboard boxes in the not too distant future. We'll have to wait until Z68 for that to happen.

Even then, Lucid's Virtu will still likely play a role in those systems. History We first met LucidLogix now just Lucid 2.

If it does, then is it the rated 'Idle' power, or something even less since it is maybe just spinning its fan s? From the power consumption table in the article, it seems that under Virtu, the was using nearly 90 W at idle - Privacy Policy.

I keep hearing about a software called Virtu, Just wondering what is it? Is it like Software SLI or something? Also does it work with Ivy Bridge?

Sep 27, 8, 1 34, It works surprisingly well with things like 3D CAD, but for gaming it's not really worth it - it causes more problems than it's worth for an extra 5 FPS.

Also it is less of a parallel processing algorithm and more a task scheduler type program. I've not taken the sensible step of re reading that review but if I can recall it correctly, virtu distributes workload between the gpu's according to complexity of the load so that it can power down the gpu below it's idling point when a task is simple enough to be handled by the IGP.
