OpenCL version

Greetings,

I was experimenting with OpenCL on my machine using the software stack from a hardware vendor other than Nvidia and when I list the device capabilities it shows Nvidia at OpenCL 1.2.
Is this really the case, ie is 1.2 still the latest OpenCL supported by Nvidia or could it be the software stack from the other vendor causing a low version number somehow?

Thanks in advance.

Yes.
