T400 Switchable Graphic Card Problem

2008-09-03, 2:11 AM

Hi,

I have been using T400 for days, and I found a problem with the switchable graphic card, actually it's with HD3470 when enable the switchable graphics.

Here we go. When I enable the switchable graphic card in BIOS, and select HD3470 in Windows, the memory usage of some games keeps growing. I have tested several games such as NFS11, PES etc., the memory usage of the game's process can reach 1G easily in serveral minutes, and just keeps growing rapidly, never stops. But the problem disappeared when I switched to X4500.

Then I went to BIOS, set to use HD3470 only, games also ran properly, no memory issue at all. It seems the ATI driver is not so compatible with the switchable function.


Does any other T400 users face the same problem? 

 

Thank you.
