OK im sure this is covered countless times, but with the speed of builds that come out things change.
I know there are a few different factors as in the input lag can be put down to the device used, however with speaking to a few people that USB is now less a factor than it use to be. The video can also lag depending on monitor.
I was told the GGPO FBA lags and people play on a different speed setting... (not 100% certain of facts).
so what is the most accurate emulation of ST out there??
