I've recently taken notice of csrss.exe and dwm.exe using a small percentage of my GTX 1070 (only about 3% at this point). While this is hardly notable compared to everyone's issue here, it was curious enough to draw my attention. After skimming through Reddit and Microsoft threads, I ran across a few interesting troubleshooting possibilities.

1. From Task Manager find dwm.exe, right click, go to details, right click again, check if priority is set to High. If so, reduce to Normal
2. Access the NVIDIA Control Panel and change dwm.exe to use Integrated GPU, though dwm.exe may need to be added manually, and using integrated GPU may not be an option for all.
3. Some Dell Support Reps seem to believe Kaspersky software and SmartByte Drivers/Services may be a contributing factor to this issue, to which they've advised to uninstall both, should you have them.
4. Dell users have also reported some improvement by way of updating the BIOS and the Dell Delivery Application. Sources for these are as follows:

Dell Digital Delivery Application (http://www.dell.com/support/home/au/en/audhs1/drivers/driversdetails?driverId=YD63W) which was updated on 4th June 2018.

Dell XPS 15 9560 System BIOS (http://www.dell.com/support/home/au/en/audhs1/drivers/driversdetails?driverId=HJKH8) which was updated on the 26th April 2018

In an effort to determine a more definitive cause, I'm attempting to research the offending process's dump files and, via SysInternals, their thread and module behaviors as well. Just on the surface, I have seen several interactions with dll files from Kaspersky, as well as a component of Windows Framework... Microsoft.UI.Xaml.

I've been unable to pinpoint any specific cause or reason as of yet, but as widespread as this issue seems to be, I'm beginning to lean towards a software issue on Microsoft's part... communicating and/or interacting with particular hardware incorrectly or inefficiently.

[EDIT] Please note that this has/is affecting users with graphics cards that are not integrated OR manufactured by Intel. The symptoms appear to be the same, but the remedy to these issues may end up being totally different. To post an update to my problem in particular, dwm.exe seems to be using more than I originally mentioned. It is now increased to around 6% to 10%.

While I'm putting efforts into resolving my own issue, I can't help feeling doubtful that I'll succeed... on that note, I'll check back with the thread, here, and hope for progress of any kind. If any of the suggestions I posted above prove helpful to anyone, it may actually be helpful to post back with information about your system (hardware AND software).
