the asus zephyrus 2015 is a unique
gaming laptop with two screens
but just how well does it actually
perform in games i've tested 21 titles
at all setting levels and compared it
against some other laptops to find out
i've got the highest specs available in
the duo 15 but it is also available with
lower tier hardware options too
you can find examples and updated prices
linked in the description
the asus armory crate software lets you
select between different performance
modes
i've used manual mode as it boosts the
fans higher than turbo mode
and applies a small gpu overclock the
software also lets you disable optimus
for g-sync which will give us a
performance boost
by default max-q dynamic boost is
enabled meaning the gpu should be able
to boost higher when the cpu doesn't
need the power and i saw it average 100
watts under stress test
we'll only be covering gaming
performance in this video so if you're
new then get subscribed for the full
review which will cover
everything else like the dual screens
and thermals we'll start out by going
through all 21 games at all setting
levels then afterwards we'll see how
other laptops compare
red dead redemption 2 was tested using
the game's built-in benchmark tool we're
not quite able to reach 60 fps at ultra
settings
but only the best and thicker machines
seem to be able to manage that still
fair results for this heavier test
though battlefield v was tested in
campaign mode
and the results at ultra settings were
one of the best i've ever seen from this
game on a laptop
but we'll see how the duo 15 and others
compare in this title and more soon
control was tested with and without rtx
enabled i've got the results with rtx
off in purple
rtxon in the green bars which was
actually still somewhat playable then
rtxon with dlss enabled as shown by the
red bars
which was running much better while also
looking good shadow of the tomb raider
was tested with a built-in benchmark
again some of the best results i've seen
from any laptop here this is another
game i'll use to compare with other
laptops shortly
apex legends was either tested with all
settings at maximum
or all settings at the lowest possible
values as it doesn't have predefined
setting presets
it was playing very well even with
everything at maximum while minimum
would get pretty good use out of the
300hz
screen call of duty modern warfare was
also tested in campaign mode with either
max or min settings for the same reason
and although there was less of a
difference between the levels here
there's still no problems playing with
maximum settings
fortnite was tested with the replay
feature and medium settings were
averaging above 300 fps
so great for the 300hz screen while low
was able to hit this even for the one
percent low
meanwhile it was running smoothly at max
settings with above 100 fps for the one
percent low
pubg was also tested using the replay
feature and even max settings was
running well a great match-up for a
144hz screen
and above 100 for the one percent low
again cs go was tested with the ultical
fps benchmark
and this game sees big improvements with
optimus disabled compared to other
laptops that are stuck with it
dota 2 wasn't too much different
compared to far lower spec laptops
though at highest setting levels it's
still above 200 fps
which is something many others don't
seem able to achieve
overwatch is another less demanding game
and was tested in the practice range
no issues hitting the 300 fps frame cap
at high settings
while even epic was above 200 rainbow
six sage was tested with the built-in
benchmark using vulcan there wasn't much
difference in average fps between
high and ultra settings and although 250
fps would still be good with the 300hz
screen
low settings gets us all the way there
metro exodus was tested using the
built-in benchmark
most parts of the game perform a fair
bit better than this so don't take these
results as a good indication of what to
expect throughout the entire game
it's more of a worst case the division 2
was also tested with the built-in
benchmark
ultra settings was just below 100 fps
but we could more than double this with
low settings
monster hunter world was tested running
through the main town and i had no
issues with the highest setting preset
it felt quite smooth with a solid 60 fps
for even the one percent low borderlands
3 was tested using the game's built-in
benchmark
again quite good results max settings
was easily above 60fps which is good for
this test while medium was able to reach
about 100 fps
ghost rake on breakpoint was also tested
with the benchmark tool
again excellent results compared to
other laptops tested
above 70 fps at ultimate is quite
uncommon and is down to the 2080 super
with higher wattage for a max q variant
assassin's creed odyssey is another that
was tested with the game's benchmark
and the results were decent here it's
challenging to score above 60 fps at max
settings on laptop hardware
far cry new dawn was also tested with
the game's benchmark
and the results were excellent here 100
fps at max settings is a nice result and
likely thanks to the i9 processor with
liquid metal the witcher 3 was doing
well at ultra settings
though it was possible to get a nice
boost just going down one level to high
settings
granted you don't really need to above
100 fps is plenty for this one i think
f1 2019 generally sees similar behavior
and although the average frame rate at
max was quite high the one percent low
seemed a fair bit lower comparatively
now let's take a look at how the asus
zephyrus duo 15 with these specs
compares against other laptops
use these results as a rough guide only
as they were tested at different times
with different drivers
in battlefield v i've got the zephyrus
highlighted in red
it's giving one of the best results i've
seen in this game only coming in behind
the much higher wattage 2080 super max p
and the msi ge75
though the difference isn't too major in
a practical sense and the one percent
low was actually better with the duo 15.
these are the results from far cry 5
with ultra settings in the built-in
benchmark
this time the duo 15 was performing the
best out of this selection of laptops
it would only get beaten by much thicker
machines with the 9900k
so another good result in shadow of the
tomb raider the duo 15 is again doing
much better compared to other laptops
it's interesting that it's beating the
higher wattage 150 watt 2080 super in
the ge75 just below it though the duo
does have faster memory and the option
of disabling optimus
overall the performance from the duo 15
with this hardware is quite impressive
the i9 processor has liquid metal
cooling this is the first intel 10th
channel laptop i've tested that can run
the memory at ddr4
3200 and the 2080 super gpu is able to
boost up to 100 watts in gpu heavy
workloads due to nvidia's new max-q
dynamic boost
and these things combined are giving
good results in terms of frame rate in
games
i've tested one game with and without
dynamic boost just to get an idea of the
difference it makes
with it enabled the default the 2080
super max q would run up to 100 watts
and a gpu only load and with it off
it would run up to 90 watts which seems
to be more standard for a 2080 super max
q
anyway it was giving a little boost at
the highest setting levels which are
typically more gpu heavy but nothing
game changing
let me know if you want a dedicated
video showing the differences in more
games
the 300hz screen was useful in esports
titles
and as we saw high fps could be reached
in many games
granted with lower setting levels this
is in part due to the option of
disabling optimus
which is required to use g-sync and this
offers a performance boost as the
integrated graphics is no longer a
bottleneck here are the screen response
times for the 1080p
300hz screen in my unit by default asus
have overdrive enabled through the
armory crate software
and this gives us a 3.8 millisecond
greater grey response time when we
compare this against other laptops that
i've tested so far it's one of the
better results
asus also gives us the option to disable
overdrive which will increase the
response time a bit to 7.2 milliseconds
however it does remove the overshoot and
undershoot in some transitions
i've got a link in the description if
you need an explanation on what all
these numbers mean
let me know what you thought about the
gaming performance from the zephyrus duo
15 down in the comments
and if you're new then get subscribed
for the upcoming review where i'll test
out everything this dual screen machine
has to offer
