So I built a brand new gaming system, and I'm getting strange FPS results while 5 boxing. I'm using ISBoxer, and its set to the default 30 FPS background 60FPS foreground, and i have Vsync turned on, with triple buffering (Didn't see much difference with it off either). My FPS is either 60FPS, or 14FPS. I played around with the overall video settings slider, and the higher I go, it only seems to affect my top end FPS, but still often goes down to 14. Is there anything else I can try? I just upgraded from a Q6600 OC'd to 3.4GHz, and I'm now running a core i7 @ 4GHz. I had similar issues with the Q6600, but my CPU was always at 100% while boxing, the core i7 is barely at 50%. Single boxing, or up to 3 boxing I never get any hint of slowdown. System also plays Starcraft 2 maxed no problem.
