OK, thanks very much! Still can't get them to work, but the investigation continues.

OK, just got a Lenovo IdeaPad Y510P, running Windows 8.1 64-bit....which has both Intel 4600 graphics and an NVIDIA GeForce GT 755M card. Yes, you guessed it...I'm getting the "unsupported hardware, update your video drivers" error. I have a control panel for the NVIDIA card...certainly have the latest driver. And it's not the Windows driver, I'm using the NVIDIA one. I've even tried disabling the Intel 4600 so that only the NVIDIA card is working. Still no success. I've tried the Second Life Viewer, Singularity (32- and 64-bit) and Firestorm...even Imprudence...same thing. I figured it was not in the GPU table but I found this entry in the Singularity file: NVIDIA GT 7xxM.*NVIDIA .*GT *7.* Could it be that this entry is wrong? That it has to be "GeForce GT"...etc.? If it's not the GPU table, what could it be?
