PowerCoreTools: 3ds Max's CPU management tool

8 votes


Just released version 1.2 of my PowerCoreTools CPU managment script for 3ds Max

A tool to control CPU usage while 3ds Max is rendering. Automatically sets process priority and affinity ( the number of  CPU cores the render process uses) at render start. Restores the initial settings when the rendering is done. Can be configured to run in a complete transparent  No-UI mode, which is launched right after 3ds Max has started.
This keeps your workstation responsive for other tasks while rendering. A second 3ds Max session stays responsive and can be used to continue work on different tasks.

A look at the following screenshot will probably tell more than thousand words:

Use the tooltip pop-up's on the UI elements for detailed info. As this is a tool for advanced usage, basic knowledge of CPU priorities and affinity settings are presumed.

Just use the install package ( the xxx.mzp file) and drop it onto your 3ds Max viewport.
Choose one of the install options and the tool is ready to be used. A 3ds Max restart might be required
The install package provides an uninstall option too.

New features in V1.2 are 3ds Max 2017+ compatbility and support for 3ds Max's ART renderer. Currently MaxToArnold is limited, as this renderer manages  CPU resource usage by itself.

Thank-you so much!!

I have wanted something like this for the longest time. Precisely so that I could continue to work in another max session while rendering. Excellent work!

Only if you use one Max

Only if you use one Max session to render ( with accordingly tweaked PowerCoreTools options ) and continue to work in a second Max session.
The second Max session would be more responsive if you limited the first one to not use all cores and/or low priority during rendering

looks great dude,
i wonder if this improves the viewport performance in any way?
