Hello, don't know if this is a good place to ask this but I'm asking here because there are a few technically knowledgeable people here so here goes.

I currently play arcade fighting games through emulators on my PC with an arcade joystick. I notice that I get a bit of input lag when I play, and its even worse when I play versus other people online through GGPO (ggpo.net) and 2DFighter (2dfighter.com)

I was wondering if it was possible to use one of the various USB rate changing programs to make my joystick perform a bit better. The one that I had in mind was Sweetlow's HIDUSBF. I wanted to use this one because it wouldn't change the rate for all of my usb devices.

The program recognizes my joystick and I was able to change the rate to 500Hz but I'm not sure if it actually works or not, would there be a way for me to actually see if its working 100%? Or any tool i can use to measure the frequency?

Im also using Win7 so I followed this guide http://www.ngohq.com/news/15043-how-to-increa...a-7-a.html

Any help/thoughts/insight would be most appreciated.
