Loosing your touch? Getting too old? Check your TV for game mode

A little piece of essential gamer advice: So I bought a fancy new TV and a PS4 a bout 6 months ago. I booted up Battlefield and got torn up. Again I tried PvP in Destiny and got torn up. I thought I was loosing my touch. I wasn't the best at shooters but I usually gave more than I got and was pretty frustrated by this drop in skill. So while reading some stuff on Destiny, I saw a comment about how Samsung TVs and most flat panels have game mode (reduces the processes & time it takes the image to display but reduces quality slightly). so I found the settings, switched to game mode and tried out BF4 again. I got to tell you it makes a huge difference! Its almost unnoticeable, the delay is so slight but it's enough to make you miss that headshot or that long sniper shot. Even though I'm not as well practiced as I was in college, I feel like my old gamer self again! Thank you random redditor!
