<pre>There are some known performance problems with UVD. I don't believe we know why
it is slower than fglrx yet. Maybe something subtle related to UVD setup.
Tiling is also disabled for UVD surfaces at the moment. This slightly reduces
throughput, especially on GPUs with little memory bandwidth (such as APUs).</pre>
