# Cemu detailed changelog for 1.21.5
# Patreon release date: 2020-10-30
# Public release date: 2020-11-06
general: Added a new CPU mode option called 'Auto' (#222)
When selected it will use Single/Dual/Triple-Core recompiler depending on the number of physical cores on the host system
1-2 cores -> Single-Core recompiler
3-4 cores -> Dual-Core recompiler
5+ -> Triple-Core recompiler
If the CPU mode was not previously set then Cemu will default to 'Auto' (earlier Cemu versions defaulted to singlecore-recompiler)
