This is the stuff that keeps me up at night

What I really love about this channel is the expertise and research when it comes to gaming hardware and software but also how you are apparently very good at video games in general. Perfect match I would say! Information and personal experience to back it up :D

[jggg]

Yeah this is absolute Gold, I'm going to be running uncapped, Adaptive Sync Off and with Reflex or AMD Antilag ON now. Thank you.

This was generally a very and informative rundown on input lag etc. The one thing it could have touched upon a bit more though is one of the main reasons for capping your fps to maintain a consistent input latency, muscle memory. That's why many people want a consistent frametime and to minimise any differences, your brain does notice it, even if we don't really "see" it.

Great video. As others have noted, Battlenonsence showed caping framerate so GPU is only working less than 95% usage provides a stable frametime and consistent input delay. I used to run uncapped on battlefield games, but since capping the frame rate it’s definitely more smooth, no more stutters and my aim has improved significantly.

One point about capping at monitor refresh rate - I find the smoothness of capping to be more beneficial in most games other than CSGO and Valorant, while I keep frames uncapped in those games. Essentially, when you're receiving information at a regular interval with a constant input delay, I believe you can do things like tracking more easily. When you have uncapped frames, you're receiving information with varying input delay, which can make tracking look a little more jarring which affects your aim.

Thank you for the informative run down while applying your explanation in the real world. The fact you actually play FPS games at a high level and are most interested in giving yourself a competitive advantage makes your content so much better than any mainstream tech channel.

Blurbusters recommends Vsync enabled w/ G-SYNC + frame cap for best performance and no tearing. Vsync "off" + G-SYNC can still have tearing.

[markusransberger]

FYI: you can cap your frame rate in the Nvidia Control Panel.

Also when I remember correctly, Battlenonsense's older tests showed, that you should cap your fps a bit below your monitor's refresh rate. For example, use 140 fps as a limit with a 144 Hz monitor.

Saved to Watch later (at work) and already know it deserves a thumbs up.

[LordVerdo]

Great video! I think I would recommend capping frames in the Nvidia control panel because RTSS, as awesome as it is and something I’ve used for years, it can cause trouble for certain games. For example, Elden Ring won’t load into a save when RTSS is on.

[papaowen]

THANK YOU!!! I've been having a lot of issues with stuttering in games and I've been trying to find good performance orientated videos and I found this gemstone. Thanks for always making such high quality and easily understandable content!

[LiquidHaus]

Love the work you're doing nowadays, man! It's great watching your channel grow so much! Keep it up!

[SpookySkeletonGang]

I like frame caps because it stops your GPU from going full force, which means it runs WAY quieter and with less power. Sometimes it can be virtually silent with good fan profiles.

[casiquekibra]

Love how you're low-key an Apex beast

[orange]

The main reason why I framecap in Apex is specifically for muscle memory while supergliding. It may be just me, but I feel a lot more consistent at a steady 150 cap than 170 ish spiking and dropping on my 1080 ti.

[Roman-zqwp]

You're supposed to use g-sync with v-sync (not in-game but in the nvidia control panel) with the framerate capped just a few frame below the max of your display. This is ideal for a few reasons:

1. G-sync turns off when the frame rate goes beyond the monitors maximum refresh rate which will cause v-sync to kick (capping the frame rate) and will introduce input lag.

2. V-sync prevents screen tearing

3. The cap ensures the system stays within g-sync's operational range

When you game like this, v-sync doesn't introduce additional input lag because the framerate is already capped (thus v-sync doesn't have to cap) and v-sync is only there to prevent tearing, enhancing your experience.

I suppose as OP explains there are cases were if you don't need g-sync or v-sync then this configuration is not applicable but for many games this is ideal.

[AxTROUSRxMISSLE]

Capping your frames a bit lower than what you get uncapped is also an incredible way to keep your GPU running cooler. Just something to consider as well since that is a very nice benefit

[corentinrobin]

Optimum Tech has this terrifying ability to pump out a video precisely on the tech subject I'm currently thinking about.

At this point I believe he is the living embodiment of the Google Analytics hivemind. I can't find any other explanation.

[ishaansendave]

Thank you for the incredible video, I really appreciate the example with 200fps on a 60hz display for those without high refresh rate displays. Your content is truly incredible and is not available anywhere else on this platform.
