Getting strange fps+CPU/GPU load values on BF4.

Hello,

I just installed my GTX 660 on my admittedly weak motherboard/cpu. I was expecting a bottleneck which I'll deal with later, but got a good deal on this card and went ahead.
Current specs:
Vista-64 bit
ASUS IPIBL-LB Benicia
Intel Core 2 Quad Q8200- 2.33GHz
2 x 4GB DDR2 ram- 800MHz
MSI GTX 660 2GB
CX 430W
Playing on 1080p

Original pre-built model: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01...


I was comparing my GPU and CPU values with my average FPS, and something isn't matching up. I got all of these numbers on the Testing Range. At all settings my CPU usage ranges from 70-80%. My GPU load only goes to 60% max, with VRAM maxing at 840MB, and core clock maxing at 960MHz.

On Ultra (without MSAA), I'm getting 40fps.
On High (which is my auto/default settings), I'm getting 48fps
On Medium, I'm getting 55 fps.
And on Low, I'm getting only 62 fps.
I would be expecting much greater fps on lowest, considering my CPU usage is not hitting 100% here. Plus from what I've read, fps changes are usually much more significant at each level.




Could this be due to one of the following:
1. PSU weak (even though I calculated enough wattage). If so, how can I check my power consumption?

2. Windows Vista- 64 bit not optimized well enough?

3. My motherboard PCI-e1.1 x 16.0 slot?

I was having the exact same problem, what i did was underclock my GPU, this increased my FPS as my CPU is also a bottlneck in my system. in battlefield 4 on ultra with a R9 280X i was getting 32-60 frames when i underclocked it i get 50-60!

Do you think I can do this safely with this old rig?

YES! i doesn't take any real knowledge to underclock you first need to get software that will allow you to underclock like MSI Afterburner, from there just tone down your clock speed and test it in game, if it gets better tone it down again then repeat until you don't see any increase in FPS

and i mean UNDERCLOCK not overclock under is slowing you gpu down to the cpu can catch up!

Okay, so I don't have to worry about voltage adjustments that overclocking typically needs?

No, what im saying is just slow your GPU down, lower the clock speed. im not asking you to increase the speed im asking you to do the opposite and decrease the speed this will allow the cpu to be less stressed and when i did it i had more stable and higher FPS
