I don't know if this is the right place to ask...I'm having some troubles with my PC, unexplainable slowdowns and such.

My real question is, anyone know a program that could tell me what's the cause of the slowdowns, for example where 1.4GB of my RAM goes, the taskbar only show about 400GB?

For another example I think Demigod should work flawlessly on my PC (I might be too naive), but it runs at 13-18 FPS with a resolution of 1920x1200 everything on high and 4X AA. But if i set the fidelity to medium the framerate jumps up to 20-23. (BTW my memory usage while playing demigod is still only 73% so I doubt it's the memory.)


My laptop (an Asus G71V-7T044C):

OS: Windows Vista 32bit SP1
CPU: Intel Core 2 Duo T9400 2.53GHz
Memory: 2X2 GB DDR3 800MHz (I know Vista32 can only really use 3 Gigabytes)
VGA: nVidia 9700M GT 512MB (1 GB of RAM is allocated to the video card, I don't know how this works or if it's good or bad)

Here's my DxDiag: http://rapidshare.com/files/201299973/DxDiag.txt

Thanks in advance!
