X-Fi's Crystalizer and Framerates?

Published by

One of the features introduced with the SoundBlaster X-Fi series is the 24-bit Crystalizer. Games, movies or mp3's sound better or at least they are supposed to. Creative even claims that a mp3 will sound better with Crystalizer enabled than it would on the CD it was taken from.

Does it really work? Well, it does but for people with low to mid range speakers or headphones. On low to mid range speakers/headphones it really is an improvement since Crystalizer makes up for the shortcomings in the frequency range. People with higher end sound setups will probably keep it disabled.

But the sound quality is not the topic here. The question is: Does my framerate suffer from having the 24-bit Crystalizer enabled or am I wasting processing power? To test this it would be ideal to benchmark some games with various Crystalizer settings and compare the results.
