I am running PhotoScan standard 0.9.0 on a 8 core Windows Vista computer without using a GPU. Often I want PhotoScan to work in the background while I am doing other work on the same PC, so it is not good if PhotoScan uses all 8 cores. I tried to de-activate some CPU cores (under "preferences"), but PhotoScan still uses all 8 cores. Is there a way to free some CPU cores?

Hello RalfH,
Disabling CPU cores in Preferences refers only to Depth maps reconstruction stage.
-
Hello Alexey,
I just tried it with 4 out of 8 CPU cores deactivated, but all 8 cores run at 100% also during depth maps reconstruction. It seems like deactivating CPU cores does not work when there is no GPU.

Hello RalfH,
Yes, it's really so. Alternative you may change process priority to "low" in Windows task manager.
-
Hello Alexey,
OK, thanks. I hadn't thought of that.
-
You should also be able to go to the photoscan.exe process in task manager and deselect one or more processors (right-click/set affinity...)

Hello andyroo,
cool feature; I didn't do much with the process manager before and didn't know that this was possible.
P.S.: Just tried it; works well. A very good thing about this method is that I can reduce CPU load while I am doing other work on the PC, and can give PhotoScan the full power when I don't need the PC for other things.
