Why was Multi-threading removed?

[LunaMoo]

No lol. Not only PPSSPP never could use "as many cores as you have", also "CPUCore" is a PPSSPP cpu core, which as follows means: interpreter, JIT or IR-interpreter and has nothing to do with multithreading.


"Multithreading (experimental)" was completely removed since it was really bad and causing a lot of device specific issues with many people ignoring all the warnings and using it anyway breaking their games just because the setting worked for someone else or even without any reason at all other than having a multi core device.
It will never return in it's old form, currently different, safer MT exists only in Vulkan backend only where it's enabled by default and does not need an option, that new multithreading method might eventually be backported to GL backend, but it will be unlikely to give same results as the broken option, so if you absolutely required that feature on some old device without Vulkan, you might as well continue using old PPSSPP versions on that device.
