Ah, yes, memory usage statistics provided were from Cycles
reported usage.<br>

<div>Just tested the memory usage, there still is a massive

</div>
<div>Generic Test scene:</div>
<div>Supported - 850mb</div>
<div>Experimental - 1408mb</div>

<div>Tried to run Mike Pans BMW benchmark but I could not get it

was too big)</div>

<div>Are you using a external program to report the memory usage
for the GPU? Cycles does not report GPU memory correctly to
blender. </div>

<div>>Firstly, thank you kindly for adding experimental GPU
SSS cubin files, </div>
<div>>what an exciting, unexpected, surprise!</div>
<div>></div>
<div>>Amazed to find Experimental cubin using exactly same
amount of memory as </div>
<div>>Supported cubin in a complex scene containing SSS.
Also, less memory </div>
<div>>than Blender 2.70a and 2.69.1 (GPU SSS test version).</div>
<div>>Understandably Experimental cubin are a little slower
than Supported </div>
<div>>cubin due to SSS calculations, but not by a massive
amount!</div>
<div>>If helpful/interested added GPGPU memory consumption
and speed test </div>
<div>>results at the end of this mail.</div>
