I used to be able to play Battlefield 4 (heavy game) on medium to high settings without the game stuttering whatsoever. Recently I upgraded to 64bit and 8 RAM. Even though the game is supposed to run better - it runs worse. I can barely run it when I'm on the lowest settings. Note that videos in media players and YouTube are stuttering too. I ran an antivirus scan (even though just formatted) and my computer is clean.
