can I check, if both cards are really rendering

[miohn]

Hi,
I checked "use all GPUs" in final render output settings,
but can I still kind a see (beside disabling and comparing rendertimes),
if really both (in my case) GPUs are rendering?
(Console gives no input about that)

Another Question:
If only one object with a seperate texture is very/sill grainy in
final render, is there a way to give only one object or texture a better
sampling?

thanks
Mike

concerning the grainy object.
Its caused by a light, which is placed in front.
I have set the light samples to 800 but still extremly grainy.

I don't want to increase the overall samples in rendersettings because of rendertimes
an because the grain appears only on this object.

What can I do?
