80 PCWorld FEBRUARY 2021REVIEWS TESTED: NVIDIA REFLEX
The monitors and mice currently compatible with Nvidia’s Reflex Latency Analyzer.Chakram Core (go.pcworld.com/chak) we
used for testing, the Logitech G Pro Wireless,
the Razer DeathAdder v2 Pro, and the
SteelSeries Rival 3. You may need to
download new firmware to enable Reflex
support. If you don’t have a Reflex-compatible
mouse, Nvidia’s setup can’t measure your
mouse latency, which prevents the full system
latency from being measured as well. That
said, if you have one of the most commonly
used esports mice, RLA still works. From
Nvidia’s reviewer’s guide:
“For mice that have not gone through our
validation process to become Reflex Latency
Analyzer Compatible, there is a mouse
database that stores the average latencies of
known mice as well, making full SystemLatency analysis still possible. We will be
adding new mice to the database as well as
continuing to validate new per-click Reflex
Latency Analyzer Compatible mice.”
Even if your mouse isn’t supported
whatsoever, you can still track PC + Display
Latency with Nvidia’s tools. That can be very
helpful while you’re optimizing your game
settings or hardware setup.
Four monitors are kickstarting the RLA
ecosystem: the Asus ROG Swift PG259QNR,
the Acer Predator X25, the MSI Oculux
NXG253R, and the Alienware AW2521H.
These are all high-end 1080p, 360Hz G-Sync
monitors, rocking the same advanced G-Sync
processor and even the same AU Optronics
panel. While bleeding-edge refresh rates
