: While Windows 98 and MS-DOS are considered the "sweet spot" for PCem, running XP often pushes the emulator to its limits, typically peaking around an emulated Pentium II 233MHz with a Voodoo3 card. Why Emulate XP on PCem?

PCem requires ROM images to emulate the BIOS of various motherboards. Delivers 100% accurate timing for software, preventing speed
PCem (short for Personal Computer emulator) is an open-source, low-level emulator that mimics the hardware of vintage IBM PC-compatible computers. Unlike other virtual machines, which create a generic environment, PCem emulates the electrical and mechanical details of actual components down to the BIOS level. It can emulate systems ranging from the original IBM 5150 from 1981, through the 486 and Pentium era, all the way to the Pentium II and early Celeron processors from the late 1990s.
Select Pentium III or Pentium 4, and set the speed as high as possible.
