CPU Core hugging and Critters Posted by Ryan Brown on 10 March 2014 05:05 PM
Summary: In version 3.1 Service Pack 1, Hippotizer reserves one CPU core for use by our rendering engine. This ensures that Windows can not assign other background processes to the CPU core running the output rendering, and thus potentially degrade playback. On HD Machines and Grasshoppers there are many (4 or 8) logical cores, so the overall reduction of CPU power available to the computer is minimal. However on a Critter, there are only two logical cores. So 'hugging' one core results in loss of half of the overall processing power. This can manifest as slower media encoding on Critters.
Solution: We have created a patch that disables Core Hugging; this should speed up background processes on critters. This is not a required patch; most users have not had a problem and should not therefore apply this patch. If however, you have noticed slow background programs and encoding on a Critter, it might help to install this.
