My specs:
i5 3570k [email protected]
16GB RAM @ 1600
ATI 5870 HIS ICEQ Turbo
2 HDD @ 7200 RPM

So First time trying out this ps2 emulator. Downloaded the latest emulator and running the v02.00 USA bios (SCPH-70012_BIOS_V12_USA_200). I love MGS so I downloaded MGS3 JP version. Everything runs great but like the scene in the beginning where they open plane door where snake is about to jump out, it lags out. Not just the visuals, but the sound as well. I remember on the ps2 you can tell visually the scene would drop frames but the sound was still in tact.

So i change the video settings to from Direct3D9 (hardware) to Direct 3D11 (hardware) and change the custom scaling of 1920X1080 and enable some AA. Now everything looks great in like the HD release of MGS collection but still see the visual lag and hear that horrible sound lag like it was being slowed down. But so far in gameplay i haven't noticed it. But i can imagine when i fight "The Fury" it will lag big time because on the ps2 i remember seeing big frame drops mainly due to the fire he would shoot out.

So any suggestions to what I can do? Thanks!
