Many 3D games stopped working with VBox latest updates under W8.1 guests

Hi,

Starting with VirtualBox 4.3.14 I've remarked that many 3D games stopped working under my Windows 8.1 guest.

Among the list :

• FarCry (before 4.3.14 the game started but there was a mouse issue)
• Warcraft 3 (worked before 4.3.14 but was damn slow while very fast under my Windows XP guest on the same machine)
• ... and many others (I can give you an exhaustive list if asked)

Interestingly, other games work like Age of Empires 3.

Host : AMD Phenom 9850 8 GB RAM NVidia GeForcfe 660 Ti with NVidia 331 binary blob Kubuntu 14.04.1 LTS 64 bits

Guest : Windows 8.1 32 bits 2 cores assigned 2 GB RAM 256 MB VRAM Configured as Windows 8.1 and not Windows 8

To perform your tests you can pick up a (French) demo of Warcraft 3 there : ​http://www.jeuxvideo.com/telecharger/jeux-et-demos/00004991-warcraft-iii-reign-of-chaos-pc.htm

And for Far Cry : ​http://www.clubic.com/demo-jeux-video-695-0-.html

Please reopen if still relevant with a recent VirtualBox release.
