does the sound be connected with the use of the nvidia card for both display and octane in the same time?

Problem with test release v1.01 noise in power supply!!!

I would like to suggest that one fix might be to give the gpu a dummy task to keep it busy when there are minimal calls happening and thereby avoid the max-min power draw issue. There might be some useful task that could be going on or it could just be a filler. Perhaps there is some compositing task or other post processing not covered as yet that could be fitted in concurrently. Some image buffering for A/B comparison or something else... ummm I dunno... like producing a bracket of exposures perhaps...or RGB channel split or.... 
...stamp info like Blender...fields?...motion blur calcs in respect of previous/next frames... ...histogram... 
...lens distortion/dispersion.. 
The results would update in the background and just be available to see/use/save if you wished.
Does anyone have ideas for more effects they might like to have or data to extract?

Sorry, but things don't work that way. All I can say is that we will have a look at what is going on try to fix it, if it's a real issue.pixelrush wrote:I would like to suggest that one fix might be to give the gpu a dummy task to keep it busy when there are minimal calls happening and thereby avoid the max-min power draw issue.

As I said in another post, no problem here with two external EVGA GTX 580 3GB in a Cubix box, with dedicated 750W PSU. Post prod works fine with no noise.

Silent Pro 1000W with one 670 GTX 4gb, no noise here. A year ago with my GTX 570 SLI and thermaltake 650W PSU sound like it will break, really weird noises, really crappy PSU. My advice, buy a better PSU.

I'm afraid I won't be happy to use post processing until I know its not quietly (or for some noisily) stuffing my PC prematurely.
Are there any more places in the code where the power draw might fluctuate like this?

One thing the developers surely can do to alleviate this problem is to implement a mechanism that would run postprocessing filters only when the render reaches max samples, before the image is being saved. Running the postpro filters all the time during "view-port updates" in case of animation or batch rendering, is a complete waste of power and just needlessly stresses the components.
Just put a "apply at render finish" checkbox, besides the "on / off" switch (or rename the on/off to "realtime preview"). So when doing animations or still batch rendering you wold check the first and un-check the latter.

It would be great if Octane could load an floating point EXR file, and apply the postprocessing to it.
This way one could have these effects without having to manage the memory of a large scene, and not having to re-render a previously unprocessed one...

To people having troubles : did you try to stop the rendering before applying the Post pro effect ? Post prod features still works with rendering disabled.
