Nsight 4.0 and GeForce GTX 860M

Hello, everyone!
I am trying to learn CUDA on my own, so I installed CUDA Toolkit 6.0 with NSight When trying to debug a program I am getting the following error: “A CUDA context was created on a GPU that is not currently debuggable. Breakpoints will be disabled. Adapter: GeForce GTX 860M”.
I have Windows 8.1 x64 and Visual Studio 2008 SP1. That is why I installed CUDA 6.0, as VS 2008 is no longer supported in version 6.5.
Device driver version is

Is GTX 860M not supported by nsight 4.0? Or do I need to install a different driver version? Where can I find this information?


I am not sure your GTX860M’s actually model, but it maybe a Maxwell chip, that means you need to install latest Nsight which have the support for Maxwell GPU, Nsight 4.0 is too old.

Just make sure you have the latest Nsight and GPU driver, then Nsight will do cuda debug smoothly. Be note, latest Nsight just drop support for VS2008, you should choose some newer visual studio.
