OpenCL support in Windows (nvidia)

Hi,

I'm using BootCamp with Windows 7 and I'm trying to run the OpenCL examples in developer.nvidia.com in my iMac with a 9400M

The problem is that it requires to install the drivers 197.13 in order to support OpenCL. The latest driver I found in bootcamp 3.1 was 188.86 which is far of the 195 minimum required by nVidia.

In Windows XP. I have tried installing 197.13 the hard way, but I didn't even know what kind of 9400M is my iMac using. I tried choosing the 9400M, the 9400M G and ION but I had the same result in all of them, nVidia control panel automatically rolled back the installation to a VGA driver. Eventually I got one of the driver to be installed, but even the most basic shaders stoped working and I didn't even tried OpenCL, and I also lost the control on the display brightness.

In Windows 7 there was simply no way of installing non boot-camp drivers.

I read in some forums that, before MacOS 10.6 was released, the only way to have OpenCL was using BootCamp, and I wonder: HOW!? Anyway I didn't find any evidence from any of the forums that OpenCL actually ever worked in BootCamp.

Does anyone know how to enable it?

Thanks!

I got openCL working but I still have the problem with the brightness.

As the card was a 9400M I was downloading the driver for notebook but imac is actually a desktop computer so I tried the desktop 197.45 driver from laptopvideo2go and it seems to be working.

I still need to try whether downloading the desktop drivers directly from nVidia will work.

Unfortunatelly I cannot control the brightness any more, which is a big problem in imac as they have a too bright screen to work with low light 😟 I think only the bootcamp drivers can control the brightness.

PS. I just tried it. The drivers directly from nVidia don't work. The driver need to be downloaded from laptopvideo2go and replace the .inf with the one provided by them.
