I have an xbox1 connected via hdmi to a Yamaha RX-V475. The TV is an older Panasonic 50" plasma. I've noticed gaming lag, and would like to know if the lag could be caused by the receiver. I plan to connect the gaming unit directly to the TV to see if I notice a difference, but I just wanted to know if anyone else has experienced gaming lag when playing Titanfall or Battlefield 4.
