Ok, since you agree it happens in rhythm games it must also exists in all other games, including shooters.
The fact is input / conversion lag is real. Milliseconds may not matter to you but they do to me so what are we debating? My mentality? Because we've established input / conversion lag is real - albeit small.
There's a reason the WCG uses CRT's with analog inputs.
I don't want to debate lag - I just asked some hook-up questions but instead of anyone giving me an answer, I just get replies about how my concern is pointless. Thank you, now how about that hook-up question, even if it's pointless?
