I have a Surface Book 2 with a dedicated nVidia graphics card as well as Intel integrated graphics.

Whenever I run a CPU- and graphics-intensive program (read: a game), I find that while ordinarily the frame rate is excellent even at highest graphical settings, at other times it gets extremely choppy.

When this happens, I flip over to Task Manager, and I nearly always find my CPU and GPU are being gobbled up by:

  • Desktop Window Manager
  • Client Server Runtime Process

So, two questions:

  • What are these?

  • Why are they constantly starting up and killing my frame rate?

These are legitimate Windows processes, which are however favorite infection points for viruses:

  • Desktop Window Manager : C:\Windows\System32\dwm.exe
  • Client Server Runtime Process : C:\Windows\System32\csrss.exe

I suggest to install Process Explorer, run it as Administrator, and verify that these processes are indeed located in the above folders.

I also suggest running several antivirus tests from well-known companies, including Malwarebytes. You will find more advice in the post
How can I remove malicious spyware, malware, adware, viruses, trojans or rootkits from my PC?

If the computer does not seem to be infected, you could reset all system components to a known state by doing a Repair Install of Windows 10 with an In-place Upgrade. This operation is equivalent to the installing of a major Windows update, so take the appropriate measures such as backups.
