Features:

  • Adds support for 'DXGI flip model', a DirectX feature which greatly improves borderless fullscreen mode performance and enables features which were previously only available in exclusive mode.
  • A functional and performance optimized physics fix (works during civil war quests, compatible with everything).
  • Ability to disable VSync in borderless fullscreen mode (with DXGI flip model enabled).
  • Refresh rate uncap for exclusive fullscreen mode.
  • Framerate limiting with separate options for the UI, map, journal, loading screen, ...
  • Lock cursor to the game window (fixes runaway mouse glitch on multiple monitor setups).
  • Reduce game startup times by skipping processing of missing plugin .ini files.
  • Fix movement controls locking up in third person at high framerates.
  • Run at any resolution in borderless fullscreen mode (BorderlessUpscale must be set to true).

Please read the detailed annotations in the configuration file (SSEDisplayTweaks.ini). Default settings should be fine for most players with high refresh rate monitors.

If you want to play at over 60 FPS on a 60Hz monitor, you'll have to set EnableVSync=false, FramerateLimit=<max framerate> and possibly adjust MaximumFramerate in HAVOK section.

Skyrim's built-in limiter is disabled by default, if you want the vanilla 60 FPS experience set FramerateLimit=60 to cap it. 

Note that fullscreen and borderless options in the launcher (bFull Screen and bBorderless in SkyrimPrefs.ini) have no effect, if you wish to change the display mode it must be set in SSEDisplayTweaks.ini (Fullscreen and Borderless options). If you want to switch to exclusive fullscreen, set Fullscreen=true.

Performance:

DXGI flip model can bypass desktop composition (DWM) and send frames directly to the screen, making windowed mode perform just as good or better than exclusive with less stutter, reduced input lag and higher framerates. Another benefit is better integration with features like HDR and G-Sync. The plugin will detect if flip is supported on your system and automatically select the best available option (if necessary you can configure it manually, see SwapEffect option in the config). 

Flip is supported since Windows 8.1, if you're running an older version use exclusive fullscreen for better performance.

Lowering frame latency may also reduce stutter, there's a detailed explanation above MaxFrameLatency option in the config I strongly recommend you read it.

Compatibility:

  • Disable Havok Fix if you use this.
  • Make sure VSync is set to application-controlled in driver options.
  • ENB: Set ForceVSync=false and EnableFPSLimit=false in enblocal.ini, configure VSync and FPS limit options in SSEDisplayTweaks.ini instead.
  • If the game won't start properly (music plays and stuck on the main menu) it's because something else is overriding Skyrim's VSync settings, either turn it off in the plugin config (EnableVSync=false and EnableTearing=false) or disable the conflicting software.
  • If you're using borderless upscaling and experiencing issues with ENB effects, set DisableBufferResizing=true in the Render section.
