ZaneZam Moderate

NEW! setting based on 'ZaneZam Optimized' which has mainly (but not strictly only!) 2 cores online -

ZaneZam Optimized

Balanced setting with no focus in any direction - DEV-NOTE: relict from back in the days, even though some people still like it! -

All you can get from zzmoove in terms of performance but still has the fast - down scaling/hotplugging behaving

ZaneZam InZane

NEW! based on performance with new insane scaling active. a new experience!
