Lucid Virtu Installation Guide

1 Introduction

Lucid VIRTU solution is designed for Intel Sandy Bridge platform with Intel Processor Graphics enabled. VIRTU
dynamically assigns tasks to best available graphics resource based on power, performance and features. There is
no need for HW or HW changes.

VIRTU allows user to fully utilize the unique capabilities of the Intel’s advanced media features on Sandy Bridge
along with the high end 3D rendering performance provided by the discrete GPU installed in the system.

When no high end graphics is used and display is connected to integrated GPU, the discrete GPU is put in idle
mode thus GPU utilization, heat, fan speed and power are down to near zero, turning the system to an environment
friendly platform.

* Currently, Lucid VIRTU solution is supported under Windows 7 / 7 64-bit OS only.

3 Hardware installation

3.1 i-Mode

i-Mode provides user with Intel Sandy special features and power saving options when no 3D gaming is used.
To use Lucid VIRTU solution in i-Mode, display must be always connected to Sandy Bridge motherboard video

output.
Note: Display can be also connected to IPG VGA output instead of IPG DVI output.

3.2 d-Mode

d-Mode is provided for demanding 3D gamers to achieve uncompromised 3D performance of discrete GPU
installed in the system. In this mode, Virtu allows user to utilize Intel special features such as trascoding, while
display is connected to discrete GPU.

Note: We recommend you use d-Mode for better 3D performance unless you use Intel Insider feature or the

power saving i-Mode.
If you use Lucid VIRTU solution with SLI / Crossfire feature, please select d-Mode.
We recommend you use d-Mode for Lucid VIRTU solution if your graphics card is equipped with dual

GPUs.
To use Lucid VIRTU solution in d-Mode, display must be connected to discrete GPU installed in the system.
