I tried searching the forums, but I couldn't come find a good solution to my problem, and I think it may be deeper than just a Mass Effect issue, but I'm not sure.

Simply put, no matter what graphic detail/resolution settings I have, be it High on 640x480 or Low on 1200x800, or any mixmatch of settings in between, after 5 minutes or so, the game will simply just start slowing to a crawl. Restarting the game fixes the issue....for another 5 minutes.

I am on a laptop, so I think the video card memory is shared with main memory.

According to Canyourunit.com, I exceed the Minimum requirements for Mass Effect by quite a bit.
CPU - Intel Core 2 Duo @ 2.26ghz
4GB of DDR3 RAM measurd at 1066mhz
nVidia GeForce 9400M with 256MB VRAM
Windows 7 Professional 64-bit


Outside of ME, Trine is the "newest" PC game I can run comfortably at high settings. 

However, I just tried the Bioshock 1 Demo, and the same thing happened -- after about 5 minutes of smooth gameplay (all at high on 1024x768) the game suddenly started lagging and slowing to a crawl.  I'm not sure if this is just an effect of trying to play these games on my video card (which shares RAM with the normal RAM of course), or if there is something else wrong. Any help would be appreciated.

Maybe Unreal Engine games just hate me :/.

Maybe you shpuld have bought a better PC:

            Looking at today's sub-minimum borderline

I was curious about how the Geforce 9400 GT related to the 7600 GT and 8600 GT, both of which were full-power Mainline Gaming parts.  The 9400 is just the prior year's 8500 GT, although the thinner die wafer increases its efficiency and reduces its heat signature, so I have also included the 9500 GT, which has the same relationship to another 8n00 card, the 8600 GT, the 6800 GT, and I threw in the 7800 GS for good measure.

nVIDIA ranks their 9400 as "1X" compared to their GTX285's 28X and GT 240's 11X (the practical ME2 minimum amounts to a 4X).

Run some tests on your RAM, good chance of some serious memory leak issues



Overheating GPU will bring your FPS down like that also, not much you can do about it on a laptop thpough
