FEBRUARY 2021 PCWorld 83marker” option that
displays a flashing
box on the edge of
the screen to make
measurements easy
and universal, but
currently, only
Fortnite supports it.
In other games,
you’ll need to
position the
monitoring rectangle
manually over your
gun’s muzzle flash (or
whatever other
animation you’re
measuring).
To do so, head into your monitor’s menu
and head to the G-Sync Processor option,
then the Nvidia Reflex Latency Analyzer
section. From there you’ll see all the options
you need to resize the monitoring rectangle
and move it around as needed. Get it right
over the center of your muzzle flash, and
make it as small as possible in the center of
the action. You don’t want light bloom at the
edges of the flashes affecting measurements if
you can help it.
OUR TEST SETUP
Phew! Now that you know everything you
need to know about Nvidia Reflex Low
Latency Mode, the Reflex Latency Analyzer
tool in new 360Hz G-Sync Esports monitors,
and how they’re totally unrelated to each
other, let’s use Latency Analyzer to measure
metrics that we couldn’t before. Are the
Nvidia Reflex options in supported games
worthwhile? Does upgrading to a more
powerful GPU or faster monitor truly matter?
How does dropping visual options to low
affect responsiveness? Now we can measure it.
We benchmarked Nvidia Reflex on our
standard graphics card testing system, which
includes 32GB of RAM and an Intel Core
i7-8700K overclocked to 5GHz on all cores.
You can find the specifics here (go.pcworld.
com/sphr). We tested the GeForce RTX 3080
as a high-end option, and the original
GeForce GTX 1660 for a more mainstream
comparison. We tested Valorant and FortniteYou’ll need to use your monitor’s OSD to move the monitoring box around.
