stuff like this is genuinely entertainment to me, really fun watching you do and explain these tweaks, thanks for this video

[swanlon]

I don't normally comment on videos but just wanna say that despite me having years worth of tweaks, following this guide made my latency be even lower, feels so smooth and fast! Thank you
!

[SLCKSHOT.]

AMAZING VIDEO my friend, genuinely a video that actually helps. my latency in game went from 15-20 down to 6-8, i didnt do everything like the services and stuff but the BIG CHANGE was putting my gpu to the lowest used core. Now that my friend was the icing on the cake lol

[Pixelz__]

I did just the power settings step and my latency has went down significantly thanks so much bro

[infernalkmt]

This is one of the most important videos on youtube for me. Keyboard & Mouse optimization amazingly affected while playing Steam PUBG. Controling character is very smooth more than ever. Thank you bro.

[harshkumar]

Great video. I think the interrupt affinities made the biggest differences for me. Everything else was already optimized for the most part.

[misterringer]

This was an absolute lifesaver for me. Thank you!

I only did basically the first half of the video, but it seems to be enough that I can now properly run audio production applications with excellent performance and no interruptions. I'm on a 13th gen intel laptop.

[supfgko]

thank you you save me a lot of time and nervs. My cores were unparked but those addiotional settings on cores in the beggining of the video helped a lot, plus disabling HyperThreading... dont know do i need to continue to watch haha, latenct already is very low... Wish you and your family best health, same as for everyone who read this <3

[elwaso]

hey thanks for the guide, I haven’t tried disabling services/devices nor debloating NVIDIA driver yet, but the other optimizations really helped me, I have half the latency I had before. And my Windows isn’t broken! I even feel my keyboard much smoother. Thanks.

[jannik]

absolutely brilliant information and easy to follow. I'm more of an audio guy who rarely plays games and this helped me with recording at very low buffer sizes. biggest issues where nvidia drivers and ntoskrnl. thank you so much!

I also am not a serial commenter on YT, I could count them all on two hands. But I am here right now to tell Neo thank you. I was ready to do my annual Windows 10 clean install when I came across this tutorial. After the install, and some of the tweaks mentioned here, I am pleased to report that my PC has since, for the first time, been 100% free of audio glitches, video stuttering and it just feels so smooth and unrestricted. I am still running an AMD FX8350 circa 2012 and it needs all the help it can get. I stopped after the power plan mods, so there's probably more benefits to be had from this very well presented and thought out tutorial. Great job.

[baumstamp]

important to note. on NON-K intel cpus: if you disable c-states you lose your single core turbo boost and it will only achieve the all-core turbo as maximum.
example, i7-12700: will only boost to 4500 instead of single core maximum boost of 4900 ... that is a BIG difference if you need single core boost (for example in games with single render thread, which are most games)

[Ryuu]

underrated creator!! These are great if you know what you're doing. Thank!! Remember to created restore point !!

[yoshinutts]

I tried these in bits at a time. Fixed lots of latency problems for EscapeFromTarkov. Good guide.

[picaseso]

Excellent video, the links also where very informative. I like the way you explain everything and citation of the sources.

[Blewis-Diarrheo]

Interesting food for thought here. I've been tweaking DPC/ISR for years, and I never found the Interrupt Policy Tool ever resulted in better performance despite LatencyMon measurements suggesting it would. But this video does make me want to investigate it again. I'm already achieving excellent DPC/ISR measurements, but any type of improvement is interesting to me still.

42:21 for those wondering what "weird" mouse glitches could possibly mean: For me I set my mouse to single digit (7 decimal) and everything went fine BUT if I plucked in (or out) any USB device (not the mouse itself), my left and right click won't work anymore even though my cursor still moved fine. Fixed by restarting and it only did it in this specific circumstance. Just to give an example what "weird" means.

[PescaitoFrito]

When comes to pc stuff I'm very enthusiast I used to do a bunch of tweaks back in 2014, but everything started with a nice topic from steam forums in 2009 with (Cs isn't smooth) Counter Strike isn't smooth then since that day I started to notice this thing called visual lag, like the game is not smooth even at 200fps, so yeah this bring me nostalgia this type of videos, those tweaks may be like "placebo" but they aren't they actually helps when comes to press a key and less input, best reaction time, better audio, less ghosting etc, etc.

But now I would also recommend you to pay attention to the electricity in your house, like check for dirty electricity, the EMI/RFI, grab a oscilloscope check the bar of the frequency if its stable or if its has a big wave, if its has a wave means there is to much dirty in the line, so you can always but power conditioner, check your circuit breaks etc, etc.

So once the circuit breaker, all outlets are clean from electricity, next steep is to go wired instead of Wifi, as the wifi EMI from router affect not only your health but the computer part.
same situation with RFI from big antennas, there is a lot of info there about how to buy this type of sprays or materials that you put on walls or windows to reduce/cease the contamination by electromagnetic stuff, so this will at the end give you a sleep quality, improve huge your gameplay

Hope this helps, i used to do a lot of tweaks.
thanks for refreshing me with this video.

PS: I do apologies for my English, cheers.

[mellowistaken]

Awesome video! Saw some tweaks in here I’ve never seen before, and helped me realize Ive been setting my affinity incorrectly. Tweaks have made a noticeable difference. Thank you!!

[mongalvez]

Your vid helped my pc a lot!
From 40+ms pc latency to 15ms. Thank you so much, keep up the great work and more power to your channel!
