Hello,

I really need your help, sir/madam.

I am playing PS2 iso game (such as Persona 4 and Harry Potter Quidditch World Cup) on Parallels Dekstop application on my MacBook Air (11-inch, Early 2015). It runs on high graphic but slow/lag in audio, and sometimes slow in video.

PCSX2 1.2.1 run on Parallels Dekstop on Macbook Air 11

My Emulation Settings is:

Enable Speedhack - yes.
EE Cyclerate - 3 / max.
VU Cycle Stealing - 3 / max.
MTVU - yes.

(The rest of the Emulation Settings is on default. I think.)

-----------------------------------------------------------------

I really need your help to run my PCSX2 in the most effective way, lag free on audio and video would be a dream come true.

Thank you for your help.
Regards.

play it on your real PS2.
Parallels is an emulator, pcsx2 is an emulator.
basically, you're running an emulator inside an emulator, with a weak CPU and a weak GPU.
That won't do it.
