MBP Unevenly Split Processes in Windows

[s1lent.ey3s]

I have a MacBook Pro 15.4", 2.5GHz Core 2 Duo, 4GB RAM, NVIDIA GeForce 8600M GT dual booting Mac OS X and Vista Ultimate SP1. Whenever I run the game Assassin's Creed I noticed that it's been somewhat laggy, so naturally, I ran Task Manager to find the CPU usage, just to see, and lo, and behold, the processes aren't split evenly among the two cores. I attached a screenshot of the CPU usage, and I was just wondering if this is at all normal. Also note that whenever I am running anything else, the processors are, more or less, performing the same amount of work.

Is Assassin's Creed even multi-threaded? ~50% indicates the processes is a single thread being distributed. Lag isn't low frames per second as well. You might want to check your video settings.

dude, that game has bad framerates on the PLAYSTATION THREE

well, as with most games this resource intensive, i did indeed expect lag. but assassin's creed was written for dual-core processors (in fact i believe its part of the requirements, but don't quote me on that). im more curious than concerned/annoyed as to why its not evenly split. i play the game, nonetheless.

I'd turn your video settings down as well. Are you patched up with the latest version and video drivers?

Please tell me how you can have lag on a singleplayer game? :D
