ASUS Z77 Motherboards - Official Support Thread

[neo_rtr]

You are doing something wrong and your issue is not related to Asus. Go and google how Lucid Virtu MVP works. And how can it be that your system dosen't list GTX680 in Device manager??? Then how did you manage to install nvidia drivers??? Definitely you are confusing something.
You should attach your monitor to GTX 680 and set it as primary display in bios.
In the same Graphics Configuration set iGPU Multi-Monitor support to enabled.
Then boot into Windows and make sure that both Nvidia and Intel HD are listed in the Device manager. Then install drivers for both.
Then install Lucid Virtu MVP software.

You are missreading
The Heaven Benchmark lists Intel(R) HD Graphics 4000 9.17.10.2792 2112Mb opposite to
NVIDIA GeForce GTX 680 8.17.13.142 2048Mb as it used to do before.
I did not mention anything about the device manager.
With reference to the BIOS settings. I tried both (auto/pcie) with no result. I removed and reseted the VGA card with no result.
I used both the original vga drivers for the intel 4000 as well as the new and even the update that comes when going to properties
At the moment iam listing driver vers. 8.15.10.2696
the nvidia driver is 8.17.13.142
The Lucid is enabled and with license status activated. both the Aug 03, 2012 release and Jun 17, 2012 have been reinstalled.

Also the biggest tell is the "in game icon" that does not appear when 3d applications running. Opposite to what it did just few days ago.
For reference the latest Intel® HD Graphics WHQL Driver for Windows 8* 64 (zip), which includes the Win7 64bit installer can be found here. -> link

Drivers are current as identified by the updater it self.
Product Detected Intel® HD Graphics 4000
Current Driver Installed 8.15.10.2696
Your driver is current.

Of course it is D-mode we are talking about.
Also forgot to add ,if i disable it from the BIOS (the i-GPU) i will get the error msg from the Lucid MVP sw that the 4000 card is not present. This proves that the card is enabled both in bios as well it is visible from within the system manager.

EDIT: BIOS cleared and re flashed, no improvement.
