Geforce FX Go5700 Problems

[esoteric]

I've had an ongoing problem with my laptop for a while. It is an Alienware Area51M 766 notebook with an nvidia Geforce FX Go5700 video card. The drivers I'm using are forceware 79.11 and the bios version is 4.36.20.44.08. OS is Windows XP SP2.

I noticed that games in general, even the not so intense directx based games, tend to decrease in performance over an extended period of time. Specifically, the FPS seems to decrease drastically. I've ran the same game on another laptop, an IBM Thinkpad T41 with an ATI Mobility Radeon 7500, and despite having inferior specs, the IBM runs the same game much faster than the Alienware. I tried updating to a newer graphics driver for the Geforce FX Go5700, using the modded inf files from here. No dice, the screen wouldn't even display a single thing and I had to roll back. I basically need help resolving this issue. Any help would be appreciated. Thanks in advance.

Try the 67.66 Drivers.

Thanks for the help.

Just installed the 67.66 drivers and performance seems to be more stable now. I also used Rivatuner to adjust the Pixel Shading in Directx, changing it to force 1.4 rather than 2.0. Directx performance does decrease over time, but not as fast as before. I'm not sure why this decrease occurs though - maybe because of heat issues? (since this notebook is notorious for overheating)

Yes it is heat most probably, try cleaning your air vents. There are tips about how to deal with overheating, try searching the forum a bit.
