<br>
I know your mail is meant for Brecht so hope you won't mind my
little bit of information.<br>
<br>
While researching instancing I tried the "19 Billions of Polygons,
not a ridiculous number anymore" compared your recent CUDA 4.2
test build designed for GTX 680, compared a recent build from
GraphicAll.org containing CUDA 4.0.<br>
<br>
With the CUDA 4.2 build I get some graphical glitches compared to
CUDA 4.0, </font><font face="Calibri">please see attached cropped
images, this </font><font face="Calibri">m</font><font
face="Calibri">ight be because I am using a GTX 460 but thought
best to let you know in case it's caused by CUDA 4.2</font><font
face="Calibri">.<br>
<br>
Thank you,<br>
<br>
David<br>

<pre wrap="">Hi Brecht,
for the upcoming 2.63 release I propose the following actions:
CUDA:
The toolkit 4.2 is still in RC phase. Although I don't have any issues
or slowdown here (Geforce 540), I'd stick to 4.0 toolkit for now.
So I propose to build the sm_13, sm_20 and sm_21 kernels with toolkit 4.0
and the sm_30 with the toolkit 4.2 for the Kepler gpus.
I am not sure if the kernels are different for Linux or Windows, if they
aren't I can build the Kepler kernels, upload, so release builders can
manually copy the sm_30 kernel into addons/cycles/lib.
Otherwise I will create the sm_30 kernels for windows only and upload
for jesterKing.
OpenCL:
As it has been confirmed by several people in the forums, I think it's
ok to enable _KERNEL_SHADING_ for OpenCL on AMD cards.
There are some reports about not working textures, so we could enable it
without textures support for now.
But I think it's good to have this tested by a wider audience, rather
than asking people to modify on their own builds.
Should be pretty save, OpenCL is marked as Experimental feature in
Cycles anyways.
Best regards,
Thomas
