its a small feature and maybe not too difficult to implement (i hope so..)
can we have a feature that could enable gpu NOT to run at full speed- the feature which we can turn on when its running on single GPU- so that navigating a complex scene and making changes is easy..?
(of course we disable it when scene is ready to be cooked)
also, since i am from CAD background, there is a habit of constantly fiddling with the workspace..in octane, i accidentlly restarted the render and lost many hours of rendered samples...some sort of viewport lock would be helpful to avoid accidental mouse clicks...
otherwise i am a happy customer.. :D :D

As Octane is a ray tracer, you just can't stop drawing and leave out some geometry. What you can do, is avoiding to calculate each pixel and just interpolate between the samples. And this is what the "subsampling" option does (one of the 3 right-most buttons of the render viewport). When you enable for example 4x4 subsampling, only 1/16th of the pixels are actually calculated and the rest is interpolated. After a few seconds Octane switches to normal sampling and you get your normal crisp render view.

thanks for going thru this..
yes, 4x4 sampling does help in easy navigation..
but maybe i couldn't explain it well..i meant a feature which could 'prevent' entire GPU power to be fully consumed in rendering only- but saving a bit of GPU power to navigate (AND modify) scene with ease..especially in complex scenes- and while running on only one GPU..
anyway, thanks for your reply... :)
