11331,VIrtualBox 4.2.6 crashes WIndows 8 guests with 3D Games,gojul,,"DO : launch Windows 8 Guest under GNU/Linux (Kubuntu 12.10 used in the example)
DO : within the guest, launch a game like Age Of Empires 3 or Age Of Mythology
EXPECT : the game works fine (at least it used to, using VBox 4.2.4 - for AOE3 this required to tweak a bit parameters to ensure minimum parameters were set)
ACTUAL : the game actually aborts the VM.

I tried to reinstall VBox Guest Additions 4.2.6 but the result is always the same.

The issue is not reproducible with Windows XP Guests on the same platform.

Host platform :
AMD Phenom x4 9850
8 GB RAM
GeForce GTX 460 1 GB RAM
Ubuntu Linux 12.10 w/ PAE kernel
NVidia proprietary driver 304.43
VirtualBox 4.2.6 installed from VBox Debian repository

Reproducitibility : always
