LucidLogix VirtuMVP is a software driver Intel
validated for the Intel Z77 platform which enables on-the-fly switching between
discreet graphics cards and Sandy Bridge / Ivy Bridge's integrated graphics
core. It does this by virtualizing one GPU or the other. If the monitor is connected to the
GA-Z77X-UD3H's onboard video outputs, VirtuMVP virtualizes the discreet videocard
(i-Mode) when 3D games are launched. Conversely, if the monitor is connected to
a discrete videocard, VirtuMVP virtualizes the IGP when required
To install Virtu MVP the monitor cable has to be
connected to the onboard VGA ports.
The main configuration screen looks like
allows the integrated graphics core to accelerate video transcoding tasks via
Intel QuickSync and seamlessly switch to purpose bred discreet videocards when
3D gaming. On top of these core features, VirtuMVP adds two new tools;
Hyperformance and Virtual Vsync which aim to improve 3D performance.
Hyperformance increases frame rates by eliminating
redundant rendering tasks and "predicting potential synchronization issues in
the graphics delivery pipeline". VirtualVsync reduces screen tearing.
Let's try HF and VV out and see what they really do.
chart PCSTATS is comparing the impact of VirtuMVP on 3DMark11, 3DMark Vantage
and 3DMark06 scores in several different combinations of Hyperformance and
Virtual Vsync, against an Intel Core i5 2500K (Sandy Bridge) Intel HD3000 IGP
and discreet Geforce GTX470 graphics card. Results in bold mark the highest
value for each particular test.
