Amnesia on Samsung R525

[trepmaws]

I actually have the same model of laptop, with the same problem. After much searching, Googleing, and going to computer repair stores, I found out what is happening. The comp IS using the 6630M card, somehow. Here the test the tech did. He ran Borderlands on high settings, and we could get an average of 50 fps. Pretty good, I thought, for the 4250 card, which he said shouldn't work. Then, he uninstalled the 6630M card, and tried running Borderlands again after the reboot. 5 fps on high settings, barely 30 on low settings. His verdict, that the primary graphics card is indeed the 6630M, but the computer is only showing the 4250 as the card being used. It even baffled him.

It's really weird, but that's how it was for me.

Hopefully that helps answer part of the mystery!
