Got bottleneck on some games

[bagusnl]

Why i get bottleneck on some games like FC 3, and Crysis 3.

when i set to high res, bottleneck is gone but fps is low an laggy

when i set to low res, gpu usage is 50~80% and cpu goes +90%.

can i fix this?

oh ya, one more.

i got a 1600MHz ram but my cpu limit is 1333MHz.

in task manager Freq just look fine. but cpu-z show my memory was 667Mhz

it just half of my cpu limit. no settings on bios. what can i do?

 

 

HP pavilion g4 1311au

AMD A4 3305M (1.9~2.5GHz) Radeon 6480G 

2 GB Single

- Your machine is extremely low spec. It isn't meant to play Far Cry 3 or Crysis 3, just so you know.

- When you are at a higher resolution your GPU needs to work much harder, and your FPS will drop, but not be jumpy due to lack of CPU horsepower.

- You should at LEAST be using Dual Channel memory to help the integrated GPU, if you're using only one stick right now.

- When at lower resolutions and the GPU is relaxed more and your FPS raises, your CPU needs to pre-render the frames (I'm just simplifying) to send to your GPU. The more frames needed, the more your CPU works. Your CPU is hitting a natural limit.

- RAM runs at half the rated speed and is simply doubled effectively (DDR = Double Data Rate). 667MHz * 2= ~1333MHz RAM, so your RAM is running correctly.
