I started playing Fable - The Lost Chapters last night and got a really strange lag. The game runs really smoothly, but it freezes for .05-.1 seconds approximately every 2 seconds. This happens during gameplay as well as cutscenes. I set all the options to minimum to see if it improved, but there was no change, so I set everything to maximum, again, no change. I'm used to everything just slowing down to a really slow frame rate if the game is too much for my system, and this isn't what's happening. It runs very smoothly with intermittent pauses. I'm about three steps ahead of your grandma when it comes to computer knowledge, so I'm not sure what you need. Here's everything.

Changed laptop settings from optimized to high performance. Opened up the NVidia control panel and set it to "Let application decide". This is where things get weird. The spinning graphic in the middle does the same thing. It rotates a quarter turn, freezes for a fraction of a second and then resumes spinning for another quarter turn. Messed around with the other NVidia settings. Opened the task manager, ran the game for a few minutes, CPU and Memory were both under 20% for the whole time, even at max settings. Tried to check for overheating. My laptop feels fairly cool to the touch at all points, but I'm not sure how to get an accurate temperature reading. Tried all XP and Vista compatibility modes. Updated all my NVIDIA drivers through their separate tool. None of these things have had any effect. What concerns me the most is the same freezing happening in the Nvidia control panel. My tech knowledge is very limited, but I can (and have for the past five hours) Google things and follow basic instructions. If you need any more information please let me know, and bear with me if I'm not great on a lot of terminology. Thanks in advance for your help.
