Programs like these tend to push the physical hardware to their limit hence the strict requirements for the graphics card specifications. Virtual machines will never be as powerful as the host, especially on the video side. They use after all a virtual graphics card, not your host's real graphics card. Applications that have high requirements on the GPU (drawing, 3D, games, video) are expected to not work as good as on the real hardware, if they work at all.
You only option is to pretty much wait for improved graphics support. I have no clue when this will happen, or if it will happen at all.
