Con la última actualización de Sonar hay gente quejandose del aumento en el consumo de CPU,pero parece que tiene su explicación;
Some customers have reported that 5.2 is more CPU hungry than SONAR 5.0.1. We have determined the conditions under which this occurs. It is a side-effect of a bug fix that was made to SONAR's dithering code for 5.2.
Before 5.2, SONAR would not apply dither to audio played out of 24-bit hardware. This was in fact a bug which was fixed in SONAR 5.2. But the bug fix means that the CPU load will increase on 24-bit hardware due to the processing overhead of dither. Note that Powr3 dither is particularly expensive.
(In a related fix in SONAR 5.2, if you are recording from 24-bit hardware but your file type is 16-bit PCM, SONAR will dither the incoming recorded signal in order to truncate the word length down to 16 bits.)
To lighten the CPU load for 24-bit hardware, you can simply disable dithering in Options | Audio | Advanced. You may want to reenable dithering when you bounce or export your projects.
