When playing Battlefield 3, I get a framerate of about 20-30 FPS. When playing mutliplayer, maybe after 5 minutes or so the framerate will drop and stay at 4-8 FPS. When a new map is reloaded this resets.

I am wondering if there is any common graphics settings for this. I noticed that Catalyst reports my video memory as 4 GB "Hypermemory". Perhaps at some point RAM is being used for video memory? (The card is 1 GB), maybe disabling this will help?

Update:
Using GPU-Z, I noticed that when this happens by GPU load % drops from a steady 100% to 0-10%. So it is as if the graphics card stops being used. The dedicated and shared memory are not going to the capacity of the card, so I don't think hypermemory theory is right.

Assuming updated drivers, the next common cause of this is overheating. I'm not sure about the 4600 series but the 4800s were notorious for throttling or even crashing due to memory overheating not GPU.

Since you got GPUZ, I'd look at the memory temperatures next.
