Hi Thomas and Sergey,<br>
<br>
<a class="moz-txt-link-freetext" href="http://lists.blender.org/pipermail/bf-blender-cvs/2014-August/067323.html">http://lists.blender.org/pipermail/bf-blender-cvs/2014-August/067323.html</a><br>
<br>
Firstly, thank you kindly for adding experimental GPU SSS cubin
files, what an exciting, unexpected, surprise!<br>
<br>
Amazed to find Experimental cubin using exactly same amount of
memory as Supported cubin in a complex scene containing SSS. Also,
less memory than Blender 2.70a and 2.69.1 (GPU SSS test version).<br>
Understandably Experimental cubin are a little slower than Supported
cubin due to SSS calculations, but not by a massive amount!<br>
If helpful/interested added GPGPU memory consumption and speed test
results at the end of this mail.<br>
<br>
---------------------------------------------------------------------------------------------------------------------------------------------<br>
In relation Blender file size increase (extra cubin files), is it
worth switching to 7-zip, at the very least for Buildbot versions?
Saving server space and bandwidth.<br>
For those on Windows not wanting to install 7-zip, there's a
portable version (portableapps.com).<br>
