that is already fixed in the Master branch, unrelated to the new
Toolkit and Volume. (Simple parameter mismatch after another
commit). :)<br>

<div>Just a heads up, in your build with volumes enabled, MIS
doesn't work for environment lighting on the GPU. Turning it
on just results in a black background.</div>

<div>Hi Thomas,<br>
<br>
</div>
I think the move to cuda 6.5 and enabling volume are
2 issues and should be treated as such. I do however
agree that we should do both.<br>
</div>
Ill update the buildbot to cuda 6.5. The cuda 6.5
cubins should work on older drivers ( pre 331 ) but it
would be good to also test and verify.<br>
<br>

Best regards,<br>

<div>Hi David,<br>
thanks for the tests!<br>
<br>
* Equi-Angular and MIS is only implemented for
Decoupled Ray Marching, which we cannot enable
on GPU yet due to Performance / Stability
issues. I will change the UI accordingly (for
example disable the button when GPU is used).
<br>
<br>
* The performance drop when using a texture is
to be expected, Decoupled Ray Marching helps
here quite a bit, I guess that's why CPU is
faster in that case.<br>
<br>
Best regards,<br>

<div>Notes: Was testing volumes and
with a simple world volume and a
lamp now it's actually much faster
than cpu (before gpu was crazy
slow). Haven't tested it with more
complex scenes. I noticed though
that in gpu volume gets always
sampled as "distance" sampling, no
matter the setting. Cpu however
respects the other settings
(equiangular, etc). In distance gpu
much faster and its also faster when
bounces are introduced, something
that in older builds really killed
gpu performance.</div>
