Fancy displays waste power and can potentially harm audio quality,
it's true!

+# CAVEATS
+
+Increasing timer resolution increases the number of CPU wakeups and
+power consumption.   This defeats the efforts of dtas-player
+configurations which use large buffers (especially in the sink) to
+reduce wakeups and power consumption.
+
+In rare cases (or poorly-configured systems), increased wakeups from
+dtas-console will also increase contention with the sound card,
+negatively affecting audio quality even if CPU utilization is not
+a problem.
