Multi-Thread Emulation?

Post by DevanDrake99 » Sun 01 Dec, 2019 9:53 pm

I've heard about the new CPU recompiler on PCem. Is it possible yet to emulate the guest CPU with not just one, but multiple cores/threads? :?:

PCem (and its forked variants) can only emulate a single core, single threaded processor. It's not possible to emulate multiple cores or threads.

VMware and VirtualBox are capable of virtualising a guest PC with multiple CPUs as they can be treated as multiple cores/threads on the host PC.

It's not possible to split single-core CPUs into multiple threads.

PCem already does use multiple threads for the other parts (Video, Voodoo lines*SLI)
