As the title says, I am running BF3 on the Lenovo g505s (here), and I find something to be quite fascinating.
Now, I didn't buy this laptop expecting to run BF3 on anything but low with FPS around 30ish.
Turns out, if I run the game on low, anti-aliasing post and MS off, native resolution (1366 x 768), I get 20-35 fps, with it hovering around 25/30 most of the time.
Now, when I tweak with the settings and set everything to ultra except ambient occlusion, and anti-anliasing (post and MS) to off, I still get 20-30 fps, with the fps hovering around 20-25.
Why isn't this APU scaling? I'm not mad, just curious, seems fascinating that this should happen. What, from a technical point of view, is holding the performance back? My layperson knowledge says there must be a bottleneck or maybe it is a fault of the speed of the integrated graphics, since there seems to be enough memory on hand for the APU to handle ultra settings (which take up a lot of memory, right?)
Anyway, I'm confused as hell and would really like to know what is going on, and if adding more RAM or something will make the low setting fps go up.
Thanks!

Mine stays at 3.2GHz most of the time in turbo mode, up from 2.5GHz.
