I've been building some dense clouds with Photoscan Standard and noticed how completely unresponsive Windows is at times, often with the mouse cursor slowing down to like 1 movement per second.  Web videos stop playing, apps freeze and all that other stuff that comes along with process intensive programs...

Not all of my resources are being used though.

I have a video card dedicated to running windows (my display card is a GTX 1060 and I have two 1080s used for rendering and processing).  There are a number of GPU rendering apps that I use in this way and because my display 1060 isn't used for rendering there's nothing slowing down the video processing for Windows.  Everything stays running just the same when I render as when I'm not.

The CPU for Photoscan has it's affinity set to 4 of my 8 cores so my processor load for the cloud building is never above 50%.  I've also set the process priority to below normal without any changes.  There should be enough free CPU overhead that Windows shouldn't be lagging like it is.

Memory wise I have 64GB in this PC and Photoscan is currently only using 5GB, so it's not a memory issue at all.

Does anyone know what might be causing the lag issues?  Currently Photoscan is really the only program I use that does this sort of thing.  I'm very used to multitasking without any problem, sometimes even rendering with CPU based software like Vue while rendering with GPU software like Octane at the same time.  Based on my system performance I really shouldn't be kept from at least watching Youtube while clouds are built.

Hello DTFrontMan,

Which version of PhotoScan you are using (including the build number)?

Usually some sub-steps of dense cloud filtering are using CPU quite intensively and system may be lagging.
