Get the Best of Hybrid Graphics on a Desktop
The Competing Standards
Hybrid graphics are hardly new, and certainly not unique to Virtu. Nvidia and AMD both offer switchable graphics solutions to achieve many of the same goals as Virtu. Nvidia’s Optimus technology seamlessly switches between discrete and integrated GPUs depending on an application’s needs or available power. AMD’s switchable graphics, while not quite as seamless as Nvidia’s, essentially does the same thing. But both Nvidia’s and AMD’s technologies are typically relegated to the mobile space, save for a single Alienware system (the X51) that leverages Optimus.

The closest Nvidia has come to offering a hybrid graphics solution for desktops is with this wee Alienware X51 PC.
We reached out to both companies to see if either had switchable graphics solutions in the works for desktop systems and got the typical answer that neither company could comment on unreleased products. Nvidia said there is nothing preventing OEMs from using Optimus on desktop systems, but that it hasn’t been done because power is much less of a concern on desktop system, especially since recently released graphics cards consume little power while idling or sitting at the desktop. A rep for AMD said something similar: “On desktop platforms, AMD leads in power efficiency with ZeroCore Power. This vastly reduces power without having to rely on solutions such as switchable graphics.”
How to Set Up Virtu on a Desktop PC
Installing Virtu on a system could not be any easier. Assuming you’ve got a compatible platform with the necessary motherboard and iGPU and dGPU installed, there are only a few steps necessary to get Virtu up and running.
1. Choose Your Mode
As we’ve mentioned, Virtu can be set up in i-Mode, in which a monitor is connected to the processor’s integrated graphics output, or d-Mode, in which a monitor is connected to the discrete graphics card. Although our tests didn’t show much difference in either mode, you’ll want to use i-Mode if power consumption is your main concern and d-Mode if game performance is your priority. To choose your mode, simply connect your monitor to the desired display output on your graphics card (d-Mode) or motherboard (i-Mode).
2. Enable Virtu in the System BIOS/UEFI
For Virtu to function, you must be using a compatible motherboard with the necessary hooks incorporated into its system BIOS/UEFI. If you’re unsure about your motherboard’s support for Virtu, reference its specification on the manufacturer’s website (if Virtu was included on your motherboard’s driver disc, chances are it's supported).
If you’re certain you’ve got a Virtu-compatible motherboard, the next step is to enter the system BIOS and enable Virtu (image A). On the Asus motherboard we used for testing, the setting was located in the Advanced > System Agent Configuration > Graphics Configuration section of the BIOS. The name and location of the setting will vary from manufacturer to manufacturer, however.

3. Install Your GPU Drivers
Virtu requires that your GPU drivers be installed before Virtu. Once you’ve got your monitor(s) connected and the necessary feature enabled in the BIOS, boot into Windows and install the latest drivers for your iGPU and dGPU.
4. Install Virtu
Installing Virtu requires no special knowledge or configuration information. The tool installs the necessary drivers and abstraction layers and automatically detects the hardware in the system. Although a Virtu installer was likely included on your motherboard’s driver disc, we recommend grabbing the most recent version from the LucidLogix website to ensure the broadest compatibility.
If you don’t need to change the default installation options, simply start the installer, accept the license agreement, and click through the onscreen prompts to complete the process (image B). If all went to plan, once rebooted, Virtu will be installed and enabled

5. Using Virtu
When the Virtu installation is complete, GPU virtualization will be enabled by default. To access Virtu’s control panel, right-click the Virtu icon in the system tray and simply choose the option to open the control panel. There are only four tabs available in the Virtu tool—Main (image C), Performance (image D), Applications, and About—and they’re all simple to navigate.
