so im running bf3 right now and im getting about 40 fps low to med settings. im monitering my cpu and gpu usage. on these settings my cpu cores are running at 1.80 -90% 2.8-90% 3. 50-6-% 4. 60-7- %

low settings on gpu and its running around 50-60% i crank up the settings to ultra and get a fps drop and the gpu runs almost full but a drop in cpu %.

does this mean bottlnecking? if so what is the bottleneck

Without hearing some of your system specs it is quite hard to say, but from your findings you can almost say it is the Card or the graphics drivers.

BF3 is a very intensive game... but more so the Graphics card than the proccessor.

o forgot to say specs lol. phenom x4 9950 (not phenom2) hd 4850 512 ram gpu 2.5 gig ddr2 ram( upgraded really needed i know)

Well that is considering the oldness of your computer. That isn't relly bottlenecking, bottlenecking is where cpu is at 100% and gpu is very low. Right now you are perfectly fine, it is much better to hvae gpu at 100% and cpu at 10-20%.

is my cpu in a normal range? how much more can it do?

It's normal, as said before upgrade to an ssd :)

Without a doubt its the graphics card and possibly your Ram.

When you up the textures your card cannot render at the same speed, this probably means your cpu usage goes down since less calculations need to take place. Another problem may well be your Ram becomming full and the your hard drive being used instead. Personally I think the latter is less likely but an upgrade to 4gb would not hurt you at all.

i see. im really new to pc gaming so thats why i post so many things here lol. so your saying if both my gpu and cpu are pretty high im not bottlenecking? cuz ill turn settings to full and get lower cpu usage but higher gpu usage. thats normal yes?

That's better! You want your gpu to be doing the work, not your cpu!

I really do not know what amuffin is talking about here.... an ssd only assists with the load time of applications and games.....

The advice he is giving here is incorrect.

Any way. My advice is to upgrade your GPU and Ram as much as you can... your CPU should not bottleneck an Nvidia 470 or Raedeon 5800 series card imo. Also an upgrade to 4gb Ram would be fitting for your system.

He doesn't have the money atm^^ you need to check his other threads! :)

ssd is down the road for me lol. so i did the right thing in purchasing a 6850 to replace my 4850. good :)  thatnks guys

You will deffo see an increase in frame rates with that card, but your CPU still will not be your bottleneck when you upgrade.

Regardless... telling somebody to upgrade a part which will not benefit the problem is the wrong thing to do.

He just wants things to load faster and not hang, according to his other thread.
