Hello people. I have an issue. I am trying to play BF3 but I only get 30 FPS on low settings. Is my CPU bottlenecking my GPU?

my specs are very similar

4GB RAM @1333
AMD HD6850 1GB (about 10->15% faster than your 4870)
Phenom II 955BE
Corsair Force 3 120GB SSD
monitor i game on is 1680x1050
no overclocking

i run with BF3 graphics on auto - most settings say 'high' and get perfect framerates - never been able to feel it drop

my cpu sits at around 80% usage on all 4 cores.

I would guess that your CPU is the bottleneck. Try find a 4 core phenom II cheap if you can.

lower your resolution to 1280x800 and watch the frames fly

thats odd, i just ran through bf3 at 848x480, with my specs and i was getting as high as 45fps. did you make sure you set the gpu to performance in catalyst?

if lowering the res really did not help, then the cpu would be the culprit

Yea I have everything that I can set in the Catalyst to performance or off. And changing the res doesn't change my FPS at all. I can switch from Low -> Ultra and I only lose 10 frames.

yea I was looking at that x4 645 for 99$. Would that be a good buy that would last for another 2 years at least?

If your ddr3 memory is running at 535 that is your problem, set it to 1333 in bios and rerun game

533x2=1066 +2 accounts for random frequency fluctuation

Changing the ddr3 helped a little bit but I am still dropping to 20 frames

the problem is your cpu isnt up to the game... your gonna be stuck in the 10-30 fps window even if you drop everything to low and run at 12/7. overclocking to 4.0 wouldnt even help you much. the game needs a tricore or better.

Maybe this will help i run a phenon l 8750 @3.0 4gigs ddr 2 1066 and gts 250 i also have a athlon2 245 @2.9, 4gigs ddr3 1333 with a identical gts 250 both are very equal in playing performance in bf3 @1080p but in a big map with lots of action the athlon drops fast whereas the tri core even though it is first gen never skips a beat.
Both av about 25-35 fps game play. Your cpu is holding you back with that 4870

Think of 1998 pentium iii is the world's TOP CPU
7 years later in 2005 this cpu is RUBBISH.

Now the same thing happens again.

athlon FX-62 introduced in 2005 with price of 1099usd as the world's fastest cpu
and 7 years later now 2012 it worth less than trash.

think of the ii x2 250 as about same performance of fx-62
(both athlon 2.8ghz x 2), using aiix2 250 is the same as using
once-top-now-rubbish fx62 cpu

above all my opinion IS:
ur 4870 = ur DDR3 4GB = GOOD
a ii x2 250 = fx-62 = USELESS TRASH

i recommend that u buy a i5 system asap.
