Hello,
For me, don’t play on PS2 becausse your option is to up.
Remove all option (bezel, shaders, retroachievement ect ect ) and see of you play (maybe change the resolution too)
It’s you “options” to lagg with computer/screen on the systeme.
My config is I5 2500 (3,3ghz) AND WITHOUT GRAPHIQUE CARD ! Only drivers hd intel and i have very appy of my hardware….ps2 run !
I think the material you are using is not good, let me explain:
You have HD screens, wide screens, HDMI cables, etc., you also have another mode than the default 4/3….
And all this makes your graphics system row
Because video games were built natively in low resolution (400×600 or 600×800) and when you enlarge the image, your hardware must compensate for the difference in output.
I had one day Killer Instinct under mame which no longer worked, just after having changed the screen and having put on a large HD screen, and indeed: when I put back a normal 4/3 VGA screen I could finally play killer instinct again.
In fact, as you have too good material from the start for graphic rendering, you forget the main main lines of emulation.
