HOW TO OPTIMIZE:
In GeForce Experience, click the refresh game list button, then BF4 should show up, click optimize. worked for me with the latest drivers. Has to be an nVidia issue, but you would think they would have been prepared for this game's release. Only one of the most played and powerful series' out there.
I know some of you already did tthis, but I saw someone post "how do I opttimize for the game"
My only issue now is that when flying it seems to be having a seizure, lol. I've heard people say its lag, butt it doesnt seem so much like lag as a graphics side twitch.
