Solved: popcount emulated for core2quads

Axxe_F_ · ‎10-14-2016

Hi all,

I'm not a programmer, i've registered just to ask a simple question:

Is it possible to emulate "popcount" instruction set on core2quads?

I have a core2quad Q9550 and I want to be able to play the pc game Quantum Break on Win10, which requires POPCOUNT.

The rest of the components are: 8 gb ddr2, socket754 asus mobo, radeon r9 290.

Thank you in advance and sorry admins if this question was already posted on the forum.

Well, you could try running the game under SDE (http://www.intel.com/software/sde) with -nhm switch to emulate the instruction, but that will slow execution down on a CPU slow by itself. So even if it works, I doubt you will be satisfied with performance.
