Reducing USB input lag?

[Fuzzy]

Tried MAME on 2 PCs, one running Win 7 and one running Win 8 - there's slight lag that I'm sure is down the the USB input rather than the screen response time.

Does anyone know a way to reduce input lag from a USB controller?

Hi

I'm just using a generic USB controller, direct to the USB port, no adapter/converter. Thanks.

How about fitting something like this?

ok for the first test then, just try whatever game you are playing but instead use a usb keyboard
are you getting any lag with the usb keyboard?

Its almost certainly how MAME is set up or the USB controller itself, not the UDB port.

Did you have any luck sorting out the lag?

Yesterday was the first time I have had a good play on my MAME system and found that the player 2 has a far bit of lag on the joy and some of the buttons.

What controller?

I have hacked some cheap SNES copy pads and not noticed any lag. I've only done this for cabinets with one set of controls though.

I have the I-Pac 2. All the connections are good and tight no loose connections.

Everything has been up dated.

This is my first system and not sure if I have missed something in a setting somewhere.

I have the I-Pac 2.

I haven't used a recent one (I think they are USB only now?). The only think I can think of is to check you are using a USB 2.0 port and that the 'high speed' drivers are installed and working. Also avoid using a USB hub.

If you have an IPAC which can also be plugged into PS/2 (& your PC has a port) it might be worth trying that too.

This, and I've done it with 2 pads no lag.
