Microsoft Windows 10 Home High End (64-bit)
Seeing as how SketchUp 8 M0 was developed in 2010, when most users were still on XP, Vista and Server 2008 (a few brave soles on Win7 or Server 2008 R2,) and the last update in that line, SketchUp 8 M5 in DEC 2012, only a few months after the release of Win 8.0, … we can understand why this version of SketchUp may not run well on any Windows version of 8.1 or higher.
Whenever you first get a new computer, it is necessary to update the drivers, as the machine may have been on the shelf (or in shipment across the ocean on a frieghter,) for quite some time.
I would suggest updating both the Intel Iris graphics driver and the Nvidia GTX 930MX driver.
Here is the latest Nvidia driver from only a month ago:
Then be sure to set SketchUp to use the Nvidia GPU via the Nvidia Control Panel.
Then if you still have issues, try running SketchUp 8 in compatibility mode for an older operating system such as Win 7 (or perhaps earlier if Win10 Home allows.)
But even in Vista and Win7 at the time when v8 was current, there were still issues then, that have been fixed since. (See the application release notes page.)
So, basically, there is no new machine you can buy with a newer operating system that SketchUp 8 will support.
(Rhetorical) How can you expect an application to run on any OS that was developed after the application ?
But really the truth is that your system is perfect for the latest few version of SketchUp, ie 2016 or 2017. You might as well give the SketchUp Make 2017 a trial run. (It’ll run in Pro mode for 30 days, then revert to Make.) You can always backsave models to v8 format using “SaveAs…” in the “File” menu.
