NVIDIA Reflex Low Latency - How It Works & Why You Want To Use It

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.

Based on my understanding (assuming I'm not missing something 😂), disabling V-SYNC in the NVIDIA Control Panel should reduce input latency while still allowing me to benefit from G-SYNC and Reflex, effectively providing the same advantages as the usual G-SYNC + V-SYNC (NVCP) + Reflex ON + Boost setup.

Am I understanding this correctly?
Not really. Vsync will have no effect most of the time. It will only have an effect when it prevents tearing due to short frames (for whatever reason, they can sometimes happen.) When there are no short frames, it won't have any effect on latency.
