Yesterday we covered the graphics hardware needed to handle Beryl (GPUs & Beryl: What is Needed?) and on the heels of that article we are taking a quick look at another Linux versus Windows comparison for the official ATI/AMD graphics drivers.

With both the Radeon X1800XL and X1950PRO the Linux binary driver had caused the frame-rate performance to be sliced in half when compared to the Windows Catalyst driver. The only benchmark that didn't see about a 50% drop in performance was Enemy Territory, which is CPU bound being based upon the Quake 3 engine. While the fglrx driver has its share of performance problems right now its image quality between Microsoft Windows and Ubuntu Linux are comparable and the Linux driver contains a number of similar features to the Windows Catalyst suite. Once AMD introduces their new OpenGL driver later in the year the performance problems will hopefully be a thing of the past.
