Thanks for the feedback. While we cannot give the source for OpenCL 1.2, you can always write that and test yourself easily. However, the main point is the fact that real penalty is in translation of...

Re: List of platforms supported by OpenCL 2.0 driver
Any plans to offer support on other models, or do hardware limitations of older GPUs (I have a HD 7870) prevent this? I was hoping to wait for the next process shrink (20 nm?), before upgrading.
