Hi:
I have an Alienware M17 x R4 laptop that has a GeForce GTX 660M video card. I thought if it is feasible to upgrade the VC, so I could use this laptop in WCG OpenPandemic GPU project. Anybody has any feasible suggestions? C E Hunt |

I have an Alienware M17 x R4 laptop that has a GeForce GTX 660M video card Probably should just wait for more confirmation if NVidia GTX 660M works for OpenPandemic GPU.Looked up both Wikipedia and TechPowerUp, NVidia 660M have OpenCL 1.2 and also have FP64 (floating point 64 bit / double precision). |

Thanks, Sam for your reply.
According to the documentation, it's certified for OpenCL 1.2 but during the GPU tests it fails. Clive |

Update to the latest driver. It might work.

I have already checked to make the video card had the latest driver installed.
