So i was messing today with SFA3 on Final Burn Alpha using a Dual Shock 2 on PC with an adapter. Then i used the XBOX 360 Wired controller to see how the sanding i did today on the d-pad worked. And i realized that my inputs were a little "different". Then i immediately used the PS2 Pad and i noticed the lag instantly and clearly, it's not a placebo effect for sure.
I heard in the past that these converters produce some input lag but i was happy with it and didn't do any further testing. And certainly in some games this little input lag has no effect and/or it's not even noticeable.
Anyone with experience in these kind of things knows a good adapter that has zero input lag? Also it would be nice if i can connect two PS2 pads instead of one, just like the one i am using right now.
Oh and i even overclocked the USB Ports to 500hz but i didn't notice any improvement.
