Windows busy icon but windows not busy

in Technical Help (nuts n bolts)

I have a recurring issue with Daz where it often freezes with the windows busy mouse icon for some time when I perform an operation like a load or mesh smoothing but none of the windows resources are maxed out. By that I mean CPU usage and disk drive usage are minimal, never more than 15% mostly 1-2% and ram is never more than 50% used system wide.

Daz does not appear to be single threading as none of my virtual CPUs are maxed out and several of them are running at 5-10% so that makes me think this is a windows tweaking issue but I have no idea what to tweak. Any ideas?

I am running the latest 4.11 beta build with a 4.2Ghz i7 4-core, 48Gb ram, 1080Ti and all files are on SSDs. Daz should be running like a bat out of hell but sadly, no.

    An application may be fully using one thread without fully using a single core on the prcessor - the load can be distributed across mutliple physical cores. Is the busy cursor associated with specific activities, or does it seem random?

    The load process is particularly bad. Not the load itself which goes pretty quick but the deleting objects phase at the start takes ages.

    Increasing mesh smoothing and collision iterations seems to take a while as well and the whole gui is sluggish when more than one figure is loaded.

    In that case I think you will find DS is using 100/number of cores% of the CPU in total - it is freeing up resources after deletion or establishing property links after load, both of which are sngle-threaded processes. The spinning disc icon shows because while doing so DS is not processing the Windows event queue, for the same reason the title bar will probably say "Not responding".

    Thanks Richard. I am assuming there is no way to speed this up short of a faster processor?

    Ah, now we'Re talking! That's the same issue that bugs me - and my machine, which isn't particularily "low end" with an Ryzen 1600, 32Gig DDR4 3200 RAM, GTX1080Ti 11GB VRAM, and everything DAZ related on NVMe SSDs. I had started another thread as to look into updating my machine, but since Mr. Haseltine has jumped in here...

    I also experiencing this problem after the scen has completely loaded, mostly when selecting IRAY as viewport. It goes to the point that all whites out and Windows suggests to shut down the program. Then again, soemtimes when I am not even touching DAZ just sitting in the background it's CPU load goes through the roof. I may add that my main screen is 4K and I am running menues etc. on a auxilary Full HD screen (which I consider upgrading to WQHD/4K at some point.

    Furthermore, I am under the (possible erratic) impression that everything ran smoother with DAZ 4.9 on my former machine which was Intel based.

    Still, currently it's pretty much dampening my creative urge. So I'd appreciate any hint what could be done from my (or DAZ') end to improve this. (Ryzen 3700X is already lurking on my workspace desk)

    The smooth shaded view with Iray preview mode is while the scene is being sent to Iray. I don't think there's much that can be done about that.

    Well being sent to Iray and thus the GPU would be fine. But why is it I see no load on my GPU and when I hit render, albeit set to GPU only i get this?

    It seems it fals back to CPU although the memoory is way below the VRAM, or am I getting this completely wrong?
