How to solve issues with shader model in VirtualBox?
I figured out: To successfully enable shader model, you need to install the experimental WDDM drivers for 3d hardware acceleration. Like described here.
- Make sure the device has at least 128MB video memory allocated (256mb recommended).
- Safe mode is not required for installing the experimental drivers.
- Devices > Install guest additions... (Host + D)
- Select: Direct2D-Support (experimental)
- It suggests to install the basic 3d driver instead of the WDDM drivers. To install the WDDM drivers, simply click No and Ok.
- Finish the installation.
- Reboot.
Done.
