<pre>In the game workload, the criteria is for FBC not to consume more power. Since
every frame requires recompression (costing power), and ideally the game is
running at the vertical refresh, there is no power saving from used the same
compressed data for more than one refresh. For this reason, FBC is turned off
under this workload.</pre>
