Hello everybody. Using the program "regshot" I found the registry keys related to DVR, a Windows 10 feature that can cause reduced performance (lag, stuttering, etc.) for some (many?) people. First i'm gonna paste the "scan" result (regshot comparison):

DVR off TO ON:

HKU\S-1-5-21-3381321717-982676326-1647861846-1001\ SOFTWARE\Microsoft\Windows\CurrentVersion\GameDVR\ AppCaptureEnabled: 0x00000000

HKU\S-1-5-21-3381321717-982676326-1647861846-1001\ SOFTWARE\Microsoft\Windows\CurrentVersion\GameDVR\ AppCaptureEnabled: 0x00000001

HKU\S-1-5-21-3381321717-982676326-1647861846-1001\ System\GameConfigStore\GameDVR_Enabled: 0x00000000

HKU\S-1-5-21-3381321717-982676326-1647861846-1001\ System\GameConfigStore\GameDVR_Enabled: 0x00000001

DVR on TO OFF:

HKU\S-1-5-21-3381321717-982676326-1647861846-1001\ SOFTWARE\Microsoft\Windows\CurrentVersion\GameDVR\ AppCaptureEnabled: 0x00000001

HKU\S-1-5-21-3381321717-982676326-1647861846-1001\ SOFTWARE\Microsoft\Windows\CurrentVersion\GameDVR\ AppCaptureEnabled: 0x00000000

HKU\S-1-5-21-3381321717-982676326-1647861846-1001\ System\GameConfigStore\GameDVR_Enabled: 0x00000001

HKU\S-1-5-21-3381321717-982676326-1647861846-1001\ System\GameConfigStore\GameDVR_Enabled: 0x00000000

tl, dr

DVR OFF:

Run regedit.exe and then go to the following keys...

HKEY_CURRENT_USER\System\GameConfigStore\GameDVR_E nabled -set to 0

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\Curre ntVersion\GameDVR\AppCaptureEnabled -set to 0

OR -you can change DVR behavior in xbox app (but you have to login).

OR -you can uninstall xbox app via powershell (run as admin) with this command (is it 100% effective?):

Get-AppxPackage xboxapp | Remove-AppxPackage

Have fun!
