Ton,
<div><br>
</div>
<div>thank you so much for the kind words.</div>
<div><br>

<div>bf-cycles,</div>

<div>We have attempted to split the OpenCL kernel with the utmost goal (of course) to get better performance on both discrete GPUs and APUs (integrated). There was been a lot of work spread out over different kinds of optimization types in order to get the
performance improvement. This has been detailed in the doc that Ton provided below.</div>
<div><br>
</div>
<div>AMD is definitely planning on continuing this work (fixing bugs, providing additional performance improvements, etc.), so please do treat this as an ongoing effort.</div>
<div><br>
</div>
<div>I'd like to express my thanks to Ton and Martijn for being supportive of our work, and of course to our engineering team for the hard work to push this out. They'll definitely continue to be active for ongoing support.</div>
<div><br>
</div>
<div>I'd like to remind everyone that feedback, bug reports, etc. are always welcome.</div>
<div><br>
</div>
<div>Thank you,</div>
<div><br>
</div>
<div>George</div>

Hi all,<br>
<br>
A couple of developers in AMD have been working for many months with trying to get smaller OpenCL kernels for Cycles. Yesterday they've posted their patch for review:<br>

Doc:<br>

<br>
Whatever the outcome is, I'd like to express my thanks to AMD and George Kyriazis for their efforts. A corporate contribution to Blender of this scale is unique in our history. I hope it will be an inspiration for others to consider to help us out as stakeholders
as well!<br>
