Hi my name is Chris and this is Battle(non)sense
Gaming products are all about maximizing your experience by providing better sound,
lower input lag as well as clear, tear-free and silky-smooth images.
This is why we have surround sound gaming headsets, gaming mice with a polling rate
of 1000Hz, gaming monitors with refresh rates of up to 240Hz as well as CPUs and GPUs powerful
enough to play games at very high frame rates.
For gaming monitors 144Hz has been the standard for the past few years, and no company which
has a reputation to lose, will try to sell you a 60Hz 'Gaming' monitor.
But the situation is still very different for gaming laptops, where even very powerful
machines capable of running very demanding games at high frame rates, still come with
a 60Hz display.
But during the last 2 years there has been some progress, as more gaming laptops hit
the market which supported 120Hz – which I believe is the absolute minimum if you want
to call that machine a GAMING laptop, especially when you decide to put a GTX 1080 in it.
So while 120Hz are nice to have, more is always better.
And it seems like ASUS agrees on that, as they now have a gaming laptop which comes
with a 144Hz IPS panel and G-Sync support for silky smooth, tear-free images.
But what is the difference between a 60Hz and a 144Hz panel.
At a refresh rate of 60Hz the panel will show you a new image every 16.66ms
You can still run games at higher frame rates like 144FPS, which does slightly decrease
the input lag as the game processes your input earlier then.
However the panel can't display those additional frames.
To benefit from such high frame rates you need one that uses a refresh rate of 144Hz,
where you then get to see a new frame every 6.94ms
The ASUS G703 has such a 144Hz panel.
To push it to its limits it also comes with a core i7 7-series CPU and a GTX 1080.
However if you go out and buy one, then you should double check the specifications of
the device, as there is also a version that features a 4k display which does not support
144Hz, at least as far as I am aware of.
Full disclosure, ASUS sent me a demo unit of this laptop to do the review.
But at the time that you are watching this video it is already on its way back to them.
I do not get sponsored by ASUS nor did I get paid to make this video.
So, with that out of the way, lets talk about the impact that this 144Hz panel has on your experience.
To test the responsiveness or button to pixel delay, I use a high-speed camera and a gaming
mouse which has an LED connected directly to the switch of the left mouse button.
Inside the game I then map the move left action to the left mouse button, and I use my high-speed
camera to record what happens when I press the left mouse button.
Inside the high speed footage, I then look for the frame where the LED lights up, and
then I count the frames until I see the action triggered by that input, which allows me to
calculate the delay between the button and the pixel.
So, with the panel running at 60Hz, the frame rate locked at 60FPS and with v-sync as well
as g-sync disabled, I measured an average button to pixel delay of 22.39ms
Then with the in-game FPS limiter set to 300 and v-sync enabled, which locks the frame
rate at 60FPS, I measured an average button to pixel delay of 76.94ms
This is why no one wants to use v-sync, especially on a 60Hz display.
Then with the same tests repeated at 144HZ, you can see how that higher refresh rate not
only lowers the average input lag, but also reduces the difference between the longest
and shortest delays, which means that the input lag becomes more consistent.
as long as you play at a stable frame rate that is.
Then I did 2 tests where I had G-Sync enabled.
In the first I locked the frame rate at 60FPS, which provided results that were nearly identical
to those that I got in my 60FPS test at 60Hz.
In the 2nd one I locked the frame rate at 140, to avoid that a small FPS spike pushes
me out of the G-Sync range.
And again, the input lag was also nearly identical with what I measured in the test where the
game ran at 144FPS and 144Hz.
So, G-Sync does not only eliminate tearing at any frame rate between 30 to 144FPS,
it also does that without increasing the input lag.
While v-sync locks your frame rate at the displays refresh rate and causes a lot more
input lag.
However, always make sure that your frame rate stays below the displays refresh rate,
especially when you also have v-sync enabled as otherwise you might suffer from the full
v-sync delay as you can see here in the results from this test, where I changed the FPS cap
to 300 inside of Overwatch, while I had G-Sync and v-sync enabled.
If you want to cap your frame rate in games that do not come with a FPS limiter, then
I highly recommend RTSS, which compared to build in FPS limiter only increases the input lag
by one frame.
You can find a link to that software in the description down below.
Now how does the IPS panel in this laptop stack up to a TN panel of a gaming monitor.
To test that I connected my ASUS PG248Q monitor to the laptop, and as you can see here,
you really don't have to worry that the IPS panel causes more input lag than a TN panel,
while it does definitely provide much better colors.
But a higher display refresh rate does not only reduce the input lag, it also makes games
look and feel smoother as you can see here in these 2 examples.
So I've been using the G703 for the last 2 weeks, and I've got to say that this is truly
a 'Gaming Laptop', as it does not only have the power to run games at high frame rates,
it also has a display that lets you see and feel the effects that playing games at a high
frame rate has on your experience.
The only complaint that I have is that it doesn't show me the currently active display
refresh rate, like gaming monitors are able to, which is a very nice feature as that allows
you to monitor if G-Sync is active and if your frame rate is inside the G-Sync window.
I hope that such can be added in the future.
Another thing is the price as the G703 is very expensive as you can surely imagine.
But I hope that ASUS and other companies will continue to push for even higher refresh rates,
in future high-end gaming laptops, so that 120 and 144Hz will eventually also become
an affordable standard for gaming laptops as they are for gaming monitors.
So that's all that I've got for you today.
I hope that you enjoyed this button to pixel delay analysis of the ASUS G703, and if
you enjoy my videos then it would be great if you could support me on Patreon, as YouTubes
ad revenue is sadly not enough anymore to run a niche channel like mine.
Without the awesome support that I get from my patrons, Battle(non)sense would not exists anymore.
You can find a link to my patreon in the description down below, where you will also find links
to my social accounts in case that you want to stay up to date on the videos that I am
working on.
So, if you enjoyed this video then please give it a like, subscribe for more and I hope
to see you next time!
Until then, have a nice day and take care,
