<pre>But I confused why game workload saved 0.1w power, and HSW didn't.
(In reply to <a href="show_bug.cgi?id=65694#c1">comment #1</a>)
<span class="quote">> 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.</span ></pre>
