RetroLink SNES Controller problem?

Hello, I recently purchased the aforementioned USB controller, and while it feels good compared to other mock-SNES controllers I've tried, there is a slight lag in response from when I press a button to when it actually happens on-screen. This makes playing a game such as NES's "Punch-Out!" near-impossible. Any suggestions? Thank you

Laq is almost always, if not 100% always, hardware issues. I had a few laq issues with my snes 2 usb adapters in the beginning but have ironed that out. My suggestion is to ditch the controller and get something better. Smart joy adapters are cheep but you do need to buy a snes pad. If you want more then just snes take a look at my sig.

Only other thing that comes to mind is a lagging computer. Just check task-man ans see if you have any memory hogs on there.
