NVIDIA Reflex SDK


The NVIDIA Reflex SDK allows game developers to implement a low latency mode that aligns game engine work to complete just-in-time for rendering, eliminating the GPU render queue and reducing CPU back pressure in GPU-bound scenarios. As a developer, System Latency (click-to-display) can be one of the hardest metrics to optimize for. In addition to latency reduction functions, the SDK also features measurement markers to calculate both Game and Render Latency - great for debugging and visualizing in-game performance counters.

Reflex provides a meaningful edge to serious competitive gamers.



Low Latency Mode

Aligns game engine work to complete just-in-time for rendering, eliminating the GPU render queue and reducing CPU back pressure in GPU-bound scenarios.

Latency Metrics

Get real time latency metrics broken down by game pipeline stage: Input, Simulation, Render Submission, Graphics Driver, Render Queue, and GPU Render. Great for debugging and for real time in game overlays.

Flash Indicator

Using the marker system, configure the flash indicator marker to draw a small white rectangle on the screen each click. This is helpful when automating the use of a tool like the NVIDIA Reflex Latency Analyzer to measure latency.
