hey, ive been experiencing low fps while playing BF3 and cant figure out why,
CPU: Phenom II dual core, 3ghz.
RAM: 4gb 800mhz ddr2
OS: Win7 64 bit
Hard drive: 500gb SATA II
Started with a Geforce 9600gt, obviously wasnt running it very well so I upgraded to a Geforce GT 440, also wasnt very good, I then upgraded to an ATI 6870 GPU and I couldnt notice much difference, even on medium I dont go above 40 fps, when my friends say they can play on Ultra with a Geforce 550 Ti?
your going to be asked to take your email down probably so i would just take it down for spam reasons.
back to the question. you were right about the gpu being slow but now you have a cpu bottleneck. contrary to what a lot of the benchmarks show(they kinda hide the importance of the cpu) you need a quad core to get good frame rates in multiplayer.
try overclocking your cpu and see if you fps go up.
