DaedalusX64 0.6, which was released yesterday, is a pretty significant update to the emulator performance-wise with its release post mentioning:

Various improvements to the dynamic recompiler have been implemented which made some titles progress from being unplayable performance-wise to running at full-speed!
These improvements were originally implemented in the Nintendo 3DS version by cmf028 but then, TheFlow ported them to the PlayStation Vita
The improvements include optimisation to various instructions, making code double-buffered, adding some missing instructions and more
A Russian translation was added by nekita13
A Turkish translation was added by rewold20

A Vita-specific issue was fixed in which DaedalusX64 crashed when being opened from other applications presumably homebrew launchers
Not setting “Wait Rendering Done” no longer causes graphics to get corrupted in some titles
Some other stuff including the nightly updater being separated from the stable releases updater and more
