I recommended a friend to buy the Acer Extensa 5635G laptop for his kid who wants to play Spore, what we later found out is that the computer lags periodically (these figures vary from time to time but the pattern is the same: 50 seconds with >50FPS, then 10 seconds of <5FPS, then 50 seconds with >50FPS and so on). Even the Acer Bubble screensaver shows the exact same pattern.
I've tried to upgrade BIOS, GFX drivers, installed XP, Vista, Win 7 to no avail, we've even sent the computer to their repair shop only to get it back unfixed.
When running 3dmark 2001 I score between 3300 and 2000 points (it gets lower every time), and everything points to a hardware malfunction but cannot really prove it.
Any thoughts? Do anyone have a 3dmark 2001/2003 score for me to compare? The test at http://www.notebookcheck.net/NVIDIA-GeForce-G-105M.13790.0.html
suggests that there's something amiss with this one.
