I recently bought and built a new computer and when I play battlefield 4 I get really bad lag and FPS, I have updated my drivers completely and added several FPS and lag fixes to my files, but it still runs horrible, I have an Intel i5-4670k, ASUS GTX 750ti OC edition 2GB, 8GB of Corsair Vengance Ram, Gigabyte Z87-OC motherboard and a WD Black 1TB Hard Drive. Any help will be greatly appreciated
