I’ve not done any comparable test but it might be worth to give it a try to see if the new Game Mode that comes with Windows 10 Version 1703 (Windows 10 Creators Update) can help you hardware intensive software like CAD. It could be AutoCAD, Revit, Inventor, Navisworks, BricsCAD, CATIA, Siemens NX, Solid Edge, PTC Creo, SolidWorks, etc.
This Windows tool is not limited to games and works for most any software. Running a software in Game Mode tells Windows that you’d like to focus on the software in terms of system resources. Unwanted and non-priority background processes will be stopped automatically or run with lower priority.
First you need to turn Game Mode on in the Windows Settings area, then enable it for each software as well. To do this, open the Windows Game Bar (Windows key + G) with the software running, and check the "Use Game Mode for this game" box. In the Game Mode Bar click on Settings to disable it for the software by unchecking “Remember this as a Game”.
You can also take screenshots and record videos with this tool.
