What NVIDIA Reflex Does ** Detailed Information **

Everything about latency. This section is mainly user/consumer discussion. (Peer-reviewed scientific discussion should go in Laboratory section). Tips, mouse lag, display lag, game engine lag, network lag, whole input lag chain, VSYNC OFF vs VSYNC ON, and more! Input Lag Articles on Blur Busters.

What NVIDIA Reflex Does ** Detailed Information **

*For this technology to work properly, you need to fix your system.
NVIDIA Reflex is a suite of technologies from NVIDIA designed to reduce system latency (or click-to-display latency) in games. It is especially useful in competitive esports titles, where every millisecond counts for aiming, reaction time, and accuracy.

Reflex helps you react faster to mouse and keyboard actions: aiming is faster, shots are registered more accurately, and the game feels much more responsive.

What is system latency and why is it important?
System latency is the time from a mouse click (or movement) to the corresponding change on the screen (for example, a gunshot muzzle flash or camera rotation). It consists of:

Peripheral latency (mouse).
PC processing (CPU + GPU).
Display latency.
High latency leads to:

Floating crosshairs and inaccurate flicks.
Issues with hit registration.
Increased peeker's advantage. NVIDIA has shown that even a small reduction in latency significantly improves aiming accuracy in aim simulators. FPS (frames per second) is important, but latency is often more critical.

How NVIDIA Reflex Works
Reflex consists of several parts and requires integration into a game via the Reflex SDK (or Streamline).

1. Reflex Low Latency Mode (main mode)
Typically, the CPU works ahead: it prepares many frames and puts them in the render queue on the GPU. This creates a buffer that adds latency, especially when the GPU is under load.

Reflex synchronizes the CPU and GPU:

The CPU sends work to the GPU just-in-time.
The render queue virtually disappears.
The CPU starts processing later → mouse/keyboard input is sampled closer to the moment the frame is sent to the GPU. The result: latency reduction by tens of milliseconds (on average, ~50% in supported scenarios), especially when the GPU is the bottleneck. Works on GTX 900 and newer graphics cards.

This is more efficient than the old Ultra Low Latency driver mode.

Why did you post this? You're just cluttering up the forum! Reflexes don't help anyone! :lol:

There are just too many authors on this forum. I also can't understand why he's writing about response time—no, not benchmarks, and not capturing the monitor's input lag—since smarter people have already done all that for him; it's all on YouTube!

Need more repetitions... :D
