so i have been trying to play bf4 without lag since the start of the beta. i have been getting 15-20 fps on lowest settings. then today i got onto bf4, and i set the setttings to ultra to see what they would look like. Somehow, i waas getting 60 fps!!!!!!!!!!!!!!!!!! i was so excited that i excited out of the game so i could record with fraps, but when i went back on, the same settings produced the result of less than 5 fps. i know i have the hardware to play this game on ultra (fx-6300, radeon hd 7790) and it even did play it on ultra lag and stutter free for a few minutes. what is the deal? i didnt change anything...
