OVERVIEW


F4SE plugin which can more than halve render latency. 

You can find more information about NVIDIA Reflex technology here.

NVIDIA Reflex optimises GPU throughput and latency to both reduce latency and improve performance in some instances. Peak FPS may be reduced in order to achieve improved responsiveness, specifically in CPU-bound scenarios. 

This is beneficial for all GeForce GTX 900 and higher NVIDIA graphics cards.

An ENB menu is provided which allows options to be changed in real-time and saved.



Additionally, a frame limit option is provided. This frame limiter optimises for low latency, so offers an optimal 30fps compared to other options. By default it is disabled.


NOTE

  • This mod is not associated with NVIDIA in any way, although functions the same as any official implementation. 
  • The bLowLatencyBoost option is enabled by default. This may increase power consumption without necessarily much benefit to performance.
  • You can observe render latency (not input latency) in the NVIDIA performance stats. For me, my "Render Latency" goes from 44 to 18 milliseconds when Low Latency Mode is enabled.
  • If you are not using a compatible NVIDIA GPU the game will be unaffected by this mod.


REQUIREMENTS

Address Library for F4SE Plugins
On Linux set PROTON_ENABLE_NVAPI=1 as the launch argument on Proton.
DXVK requires jp7677/dxvk-nvapi to work with NVAPI.


RECOMMENDED

High FPS Physics Fix
Use this mod to disable vanilla VSync which is broken. Otherwise, this mod has little to no affect on latency.

In HighFPSPhysicsFix.ini set EnableVSync = false and AllowTearing = true
In NVIDA_Reflex.ini set bUseFPSLimit = true


COMPATIBILITY

Compatible with ENB.
Compatible with Shadow Boost.
Compatible with High FPS Physics Fix.

AMD devices are only supported on Linux.
