Workstation 11 Linux Host, 3D acceleration and Windows 7 guest

Hi!

I'm using Ubuntu 12.04 with Kernel 3.13.0-40-generic 64-bit and a AMD Radeon HD 7450 and default xorg-radeon driver.

While using Workstation 10 with Windows 7 guest anything inclusive 3D acceleration works fine.

After upgrading to Workstation 11 the 3D acceleration stopped working - WS11 says the host system has no 3D functionality, whis is not true.. There was no other change made by me.

A downgrade to WS10 and it works again like a charme.

So how can I get 3D acceleration back working in Workstation 11?

TIA and HAND.
