You definitely shouldn't be lagging with those kind of specs, but it can be effected by other factors as well. Are you running other programs in the background? Try closing out as many things as you can before you play. Another more obvious one would be to play on low graphics. If none of that works it might be your internet connection (if you're playing multiplayer), or the server itself might be having issues (again if you're playing multiplayer).
I figured it out bro, i had over 10 programs running in the background haha:laugh:
