The new DLSS 4 FG has better performance, especially in 4K. If you are using the new FG in games that didn't have it natively, update the Streamline .dll files to further increase FPS.

I tested it in several games on my RTX 4070 Ti at 4K resolution with DLSS scaling enabled. My brother noticed similar performance boost on RTX 4080 after updating FG and Streamline files in some games.

Here are my results from Horizon Forbidden West, 4K DLSS P Transformer, Very high, enabled FG.
Original FG 3.5.10, original Streamline 2.2.1: 113.9 FPS.
New FG 310.1.0, original Streamline 2.2.1: 133.2 FPS.
New FG 310.1.0, new Streamline 2.7.2: 143.0 FPS.

Forza Horizon 5, 4K DLAA Transformer, Extreme settings, enabled FG.
Original FG 3.1.11, original Streamline 2.0.1: 118.7 FPS.
New FG 310.1.0, original Streamline 2.0.1: 133.1 FPS.
New FG 310.1.0, new Streamline 2.7.2: 147.5 FPS.

Streamline libraries can be downloaded from the GitHub repository published by NVIDIA, link. You can select the version by clicking main and Tags. To download click Code, then Download ZIP. There are some issues with downloading archives from GitHub, so I also included links to the individual files, sl.common.dll, sl.deepdvc.dll, sl.dlss.dll, sl.dlss_d.dll, sl.dlss_g.dll, sl.interposer.dll, sl.nis.dll, sl.pcl.dll, sl.reflex.dll.

You can also copy these files from another game, e.g. Cyberpunk 2077 2.21 or later.

When updating Streamline, always copy file sl.pcl.dll even if it wasn't originally in the game directory.

Streamline .dll files are located in the game directory. In Unreal Engine games these files are in a subdirectory, e.g. Jedi Survivor\Engine\Plugins\Runtime\Nvidia\Streamline\Binaries\Thirdparty\Win64.

Some games compatible with the new Streamline:

  • Black Myth Wukong
  • Senua's Saga Hellblade II
  • Ghost of Tsushima
  • Jedi Survivor
  • Horizon Zero Dawn Remastered
  • Horizon Forbidden West
  • LEGO Horizon Adventures
  • Forza Horizon 5

Important

Some of games (e.g. Witcher 3 NG) uses old version of Streamline and it can't be replaced due to incompatibility.

Make a copy of the original files before replacing them.

Don't modify files in multiplayer games.
