Having some framerate/freezing issues with this laptop:

[Cyalume]

Aspire Timeline U, which has:
Nvidia GeForce GT 640M LE (1GB) / Intel HD 4000 (It has been set to use the 640M by default)
Intel Core i5-3317U laptop CPU
4GB, 1,333MHz DDR3 built in RAM
Windows 7 Home Premium (64-bit) OS,

And in trying to run these two games, I get these results:
Luigi's Mansion (18-30 FPS fluctuating, 28 on AVG), 3-5 second freezes, some sound issues
Sonic Adventure 2: Battle (20-45 FPS fluctuating, 20 on AVG) 3-5 second freezes, lots of lag

Settings are:
High Performance power plan,
640M LE set for graphics processor, rendering at 640x480 windowed
DirectX 9

Does this sound about right, or is there something wrong? The games play quite terribly.

LOL. Ma boi... ULV CPUs are not made for heavy gaming. No wonder that u get bad performance.
