The PC stutters with multiple videos because Windows depends upon each program to have coded into it releases of the CPU.
Programmers are awful at programming in such releases because they impact performance and take longer to write...so that leaves Windows guessing at the right time to swap which ap gets the CPU’s attention.
Very poor architecture.

Really? You seriously need to update your superficial knowledge of Windows as Windows NT through Vista has always been preemptive multitasking. Only Windows 3.11 through 98 didn’t.
