That's interesting... do you know how they are doing this and what kind of improvements it makes? Are there any benchmarks?
Does the GPU make a lot of difference (eg. a GT120 vs. 4870 vs. GTX285)?
It's odd that Adobe claims that Flash cannot exploit GPU decode acceleration on OSX (due to lack of exposed API), yet, if you are correct, they are utilizing the GPU for some tasks with Photoshop?! 😕
Pixelmator 1.5 (it offloads to GPU but it uses Core Image, OpenCL hasn't been officially nor unofficially mentioned yet) Homepage - http://www.pixelmator.com/
I recall ATI cards (eg 4870) having some difficulty with OpenCL back in Sept. although there was some speculation over whether that was drivers or the benchmarks being used... has that situation improved at all? I did a search of the forums here and couldn't find any real updated info.
it is supported in MovieGate 3.07. see above links for more details.
other than that, like you, i have no idea what other software supports it. let's hope Apple will take the lead by Macworld 2010.
