The software approach generally has lousy performance due to the extra overhead of forwarding rendering commands between the guest and host. In addition, since this approach requires writing a completely new graphics driver for the guest, there tend to be limitations with rendering API compatibility, as well as bugs. With the hardware approach, the guest can use the GPU vendor’s normal driver.
