One of the nicest features of this new release is the addition of a DGA2 driver. To access this driver, you must be root, and run raine in a DGA-enabled XFree server. DGA is enabled by default if your X server supports it.
In short, DGA is the equivalent of DirectDraw for linux. But since it is based on XFree, it can access any graphical mode that you can define in X, and that makes it VERY interesting !!!
