This article describes a workaround for independent software vendors (ISVs) of remote display protocols to change the frame rate limit in a remote session. 

Workaround


Important
Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.


To work around the issue, create a DWMFRAMEINTERVAL entry in registry subkey "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations" to change the maximum frame rate limit on the remote session host. To do this, follow these steps:
  1. Start Registry Editor.
  2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations
  3. On the Edit menu, click New, and then click DWORD(32-bit) Value.
  4. Type DWMFRAMEINTERVAL, and then press Enter.
  5. Right-click DWMFRAMEINTERVAL, click Modify.
  6. Click Decimal, type 15 in the Value data box, and then click OK. This sets the maximum frame rate to 60 frames per second (FPS).

    Note This registry entry sets the maximum frame rate limit that the remote display protocol can deliver to the remote session client. This setting does not set the actual frame rate for the remote session client. The actual frame rate in the remote session depends on other factors such as application and computer hardware resources. Additionally, not all remote display protocols support a frame rate that is greater than 30 FPS. For example, Remote Desktop Protocol (RDP) limits the frame rate to 30 FPS. Please contact the remote display protocol providers for more information.
  7. Exit Registry Editor, and then restart the computer.
