moment-to-moment gameplay. If you’re a

competitive esports gamer, check it out even

if you aren’t interested in the 360Hz G-Sync

Esports display ecosystem.

Bottom line? Nvidia Reflex can help make

you a better esports gamer, regardless of which

facet you’re examining. The Nvidia Reflex Low

Latency Mode feature can drastically improve

responsiveness if you like games to both look

good and feel great. There’s no reason not to

turn it on. The Reflex Latency Analyzer in 360Hz

G-Sync Esports monitors serves a much more

niche crowd and needs fuller ecosystem

support to truly shine, but if you’re invested in

esports enough to even consider picking up a

360Hz panel, you’ll find it an invaluable tool in

your tinkering. We’re excited by what Nvidia’s

trying to nurture here.

If you want to go even deeper down the

latency rabbit hole, this highly technical

Nvidia explainer (go.pcworld.com/nxpl)

describing the Reflex suite of technologies is

highly recommended.

system latency used to take much more
equipment. But today, only four mice support
Reflex Latency Analyzer. Once I realized the Asus
ROG Chakram Core mouse included in my
reviewer kit delivered 0.5ms of average latency
across the board, I couldn’t really do anything
else with the information. It just is what it is.
Once more mice add Reflex Latency Analyzer
support, or once Nvidia adds a wider array of
average latency data for unsupported mice to its
database, the feature will be more compelling.
(Currently, Nvidia’s database provides average
click latency data for the top 30 esports mice, as
tabulated by ProSettings.net (go.pcworld.com/
pset), with plans to add more.)
This ROG Chakram Core (go.pcworld.
com/chak) is just as potent as the 360Hz
ROG Swift monitor, though. Top-tier gaming
mice, including the others with Reflex Latency
Analyzer support, take several milliseconds to
register a click. The ROG Chakram Core
sends its signals in half a millisecond. It’s
insane, and you can feel it in
