Hi i just bought an acer aspire 7750g-9810 and it has the switchable graphics. When i put it into high performance it uses the 7670m card. i try to play any game that uses opengl and then after two or three minutes of play it says "display driver has stopped working and recovered" i looked around online and people said that it could be the ram but i switched it out and it still said it. People also said it could be overheating but the temp only gets to 60 degrees Celsius.
you are not alone. I bought a brand new Aspire 7750G-6645 with Dynamic Switchable Graphics - 7670M. I have the exact same problem. Pretty much any game if i tweak the settings. Lara Croft Guardian of Light on any settings, Dungeon Defenders on above medium, and I just tried Diablo3 and pretty much on all settings it blue screens. I got D3 to work with limited crashes on lowest settings, and maybe none now that i did full screen windowed mode. I got the same error ("display driver has stopped working and recovered") as you if i alt+tab to windows and close program before it gets a chance to go to blue screen.
It seems impossible to update the drivers for these. I have the most current ones from the Acer website but they are not current. Right now I have CCC 2011.1013.754.12275 and AMD Display Driver 8.901.4.0000. I've contacted both Acer and AMD with no response. Also have sought help on forums and my bluescreen log shows the ati sys file as the culprit of blue screen. Auto detect from the AMD/ATI site doesn't work, and i've tried to find drivers there (latest i've tried is 12-3_mobility_vista_win7_64_dd_ccc) but anything there hasn't worked. I've also tried leschat 12.3. I've followed the guides and have run Driver Sweeper and followed steps before installing drivers, but nothing works. What a waste buying this laptop if the video card isn't going to work correctly. I could've gotten something 100-200 cheaper if this is the performance i'm getting.
so far i've only played Diablo3 on these drivers for abotu 20 minutes, but they were stable for 20 minutes on medium to high settings, whereas on lowest possible settings i'd get bluescreens every 5 minutes before.
FYI I installed 5/14 Catalyst 12.3 UP2 UnifL for Hybrid Graphics, which "includes config updates from 12.4 and 12.x":
