Metal Gear Solid 4: Guns of the Patriots [BLES00246]

Aah, good news then. You'll see these cpu's are excellent. I suspected it was probably a bottleneck problem. RPCS3 works well, but is not yet fully optimized. Now you can aim for 60fps without problems at 200% (1440p) or 300%( 3840p) if you want.
RPCS3 but also other emulators also benefit a lot from the AVX-512 if you enable it in the bios.
I wish you a good game
