NVIDIA Reflex Low Latency: On vs On+Boost Benchmarks Across Competitive Titles
Empirical input latency benchmarks using NVIDIA LDAT hardware. When to select On versus On+Boost and how Reflex prevents GPU render queue backlogs.
Demystifying NVIDIA Reflex Low Latency
System latency in competitive gaming is heavily governed by the GPU render queue. When your GPU operates at 99% utilization, frames pile up in a driver queue waiting to be processed, adding 20-40 milliseconds of latency between mouse click and pixel display. NVIDIA Reflex eliminates this backlog.
Reflex Modes Tested Across CS2 & Valorant
| Setting Mode | Render Queue Behavior | GPU Clock Frequency | System Latency (PCL) |
|---|---|---|---|
| Reflex Disabled | Unconstrained (Queue builds up) | Standard Dynamic | 28.4 ms |
| Reflex ON | Queue synchronized to 0 frames | Standard Dynamic | 14.2 ms (-50%) |
| Reflex ON + Boost | Queue synchronized to 0 frames | Locked at Peak Boost Clock | 12.8 ms (-55%) |
When to Use "On + Boost"
The "Boost" parameter prevents the GPU from downclocking during CPU-bound scenarios (such as waiting in smoke or holding passive angles). It consumes slightly more electrical power but ensures instant, zero-delay rendering the moment an enemy swings your crosshair.
