I’ve been wanting to try to organize a fighting game tourney at a local lan center, so the first thing I wanted to research was their TVs (40" Samsung LCDs) and how much video lag they have.
I used Guitar Hero 3s calibration option. In HD mode, there’s no lag at all. In SD mode (the switch on the 360 component cable), it reported between 1.5 and 3 frames of lag.
My questions are: Is using GH3 an accurate test of input lag? And is between 1.5 and 3 frames of input lag acceptable for a (more than likely casual) tourney? The games I expect to run would be (at least) 3S, CVS2, ST, and MVC2
