I bought Bf4 a month ago and it was glitchy as hell and I had to play on lowest setting , but after their latest patch I run it like a dream also a 64x OS is recommended as a 32x windows doesn't allocate enough ram for BF4 and there for u are fixed to the lowest settings and you will still lag like ****. I found that out because my friend had a 32x OS and the Campaign plays fine but multiplayer. . . not so much. Still BF4 is a great game even though it was rushed,, DICE also added a bug tracer and they are trying to improve the game as much as possible, I also saw before my friend upgraded to a 64x OS he had a LOT of problems, (example: severe lag spikes, random game crashes) then he upgraded and game worked perfectly!
