I noticed my FPS dropping a little too drastically when moving my mouse in games and I've found the cause, every time I move my mouse a ton of registry queries occur. Is this normal? If not, does anyone know a fix for this or what might cause it?

I don't know if it is even possible to disable DWM and still have Windows working normally but I found a list of solutions that can solve problems related to DWM:

Windows 10 Mouse Problems

There's a possible answer in the Windows 8.1 forum at the thread Primary mouse button resets after reboot Restores some faith as the person who answered
is a Microsoft person. That restored faith severely taxed for this being an 8.1 problem that goes back at least 2 years and somehow made it in to the next major revision.

This issue might occur due to corrupt mouse settings.

I would suggest you to make sure that the mouse settings are enabled on the Startup tab.

Follow the methods:

Method 1:

I would suggest you to check if the mouse software is running at the Startup or within the startup list. Follow the steps:

• Press Windows+R keys and type “msconfig”. Hit Enter.
• Go to Startup tab and locate the mouse software (could be Unifying software). Check the box besides the mouse icon and click on OK.
• Make the required changes for the mouse setting (swap mouse buttons) and then restart the computer.

Check if that fixes the issue. If not, proceed to the next method.

Method 2:

Let’s make the required change to swap the mouse click settings from registry and check if it resolves the issue. Follow the steps:

• Press Windows+R keys and type “regedit”. Hit Enter.
• Navigate to the following location:

Computer\HKEY_CURRENT_USER\ControlPanel\Mouse\SwapMouseButtons

• Change the key for SwapMouseButtons from ‘0’ to ‘1’.

Note: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added
protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, you can refer to the following steps to back the registry files on the computer:

• Press Windows and R key to open the run box.
• Type ‘regedit’ and press Enter from the keyboard.
• Open the File option on the menu bar.
• Click on Export and save the file with a name on the desktop.
• If you want to restore the file, you can do so by double clicking the file that you have saved on the desktop.

Restart the computer.

I think this could be related to a compatibility mode being applied to these programs.

E.g.
windows registry - Get "SIGN.MEDIA"-Id for compatibility-mode in Windows7 - Super User
