DAZ Studio 4.9 bad actor under Windows 7 rendering NVDIA iray using CPU.

in Technical Help (nuts n bolts)

I have found that when rendering with NVDIA iray CPU only that if you attempt to cancel the rendering the PC goes into a very long delay and will not give you back control of the PC. It will take very long time to recover from this. I have also found that while rendering DAZ Studio takes control of the PC and will not allow other PC programs to run normally. Believe that DAZ needs to work on their program so that it runs as a proper program when rendering.

    It will keep the CPU busy which may delay the response of other applications, but it doesn't actually stop them working. You can always open Task Manager before starting to render (or while, but if the system is busy that will be slow), find DS in the Processes list, right-click on it and either use Set Affinity to stop it from using one or more cores or lower its Priority. Rendering is a very demanding process and most users would not want these settings to be the default.

    Actually, rendering is an extremely demanding task and exclusive use (hogging everything) should be expected AND normal. 

    You wouldn't want your favorite game to be similarly hobbled?

    Yes, rendering is an extremely demanding, but Studio should allow the pausing of rendering in an ordinary procedure, not taking a very long time to stop with no indication of what it's doing.

    Task Manager is prevented from opening during this long time and when you try to use it to stop rendering it also takes a long time and will close DAZ Studio with loss of data if not saved before rendering.  During this time, you get no feedback from DAZ studio on what it’s doing. 

    This need to be improved.

    These things were 'fixed' several revisions ago, the 'stopping of a render', for example, instantly asks me to if I really want to do that. 

    Are you getting a crash when you 'stop a render'?

    @ ronkes

    I don't get that behavior when rendering and stopping a render. You have some other issue happening. The only time I get a short delay (~30 seconds) is when I stop a render before it has loaded on the GPU (i.e. very shortly after starting).

    Yeah I had this problem but the last public release fixed it all. I suppose it does depend on your system though. When I just had 8GB of RAM I couldn't;t do much at all when rendering, now with 16GB I can render a sue the net, Open Photoshop and listen to music. But again it does depend on how much ram I am using for the scene and rendering.
