Fix Latency for Good - In Depth Guide

u destroyed my windows :)

Just before trying it by myself (as I am having pops and crackles with my new audio usb 2.0 interface and a windows 10 pc): anyone has tried it for audio production and processing purposes? Thanks in advance.

I haven't tried these but the first ⅓ of tweeks seems almost exactly what Razer Cortex does.

Hyper threading- improve parallelization of computations, meaning it is for better performance doing multiple tasks at once. Also any CPU made today each core has a SMT core tied to it. this was a fix for the buggy creation engine games ( since morrowind ) Today's games will take full advantage of hyper threading.

This broke my windows, dont do it guys. I did those registry tweaks for mouse and keyboard

Do you need to update drivers with DDU every single time a new one comes out? Seems tedious if so.

urgh i dont trust this non dev user

for me if I set the keyboard data queue size too low under certain conditions some buttons don't work. When I set it too low and pressed esc in game the menu popped up like it should but when I pressed esc again it didn't close like it usually does. The funny thing was that it was 100% reproduceable and it was the only thing that didn't work properly at that specific keyboard data queue size value. So I set it a bit higher and haven't encountered anything like this again. I got an optical keyboard, too but I don't think that matters because any keyboard sends the same data via USB to the computer and the computer doesn't even know if the keyboard is optical, mechanical or something else...

great video dude, I knew some of these fixes, but you dived deeper in this

anti cheat is going to send bro to the moon💀

first screenshot u show is for audio and useful for few ppl making music and needing to have low latency on sounds if im not talking shit

thanks for this bro
you forgot something which is Using good HDMI CABLE or DIsplay port for good connect and avoid latency or lag or drop frames

Motherboard Name MSI MPG Z390 Gaming Edge AC (MS-7B17)
the block diagram in the documentation says all the usb ports are processed thru PCH tho

dont bother ,,, it will only give bad experience s ,, the 1 fps you maby gain is not worth the windows deepdive into the standard settings..
just write a powershell script and just yeetusdeletus 80 percent of windows but by that point just make a custom iso.. or write your own os..
NEWS FLASH ,, IF U WANT TO HAVE NO LAGG.. DONT USE WINDOWS !!!!!

fyi ,, everything system level based or most of it is gonna be on and enabled the moment windows update peeks its ugly head out of the windows bloat train..

my pc fucked now cant even play csgo, very nice. and the restore points i created prior are not working :/

this latency fix works man thank you for the work that you're doing you should keep doing what are you doing (by the way i have a suggestion for another video that could fix performance for good)

Mostly just snake oil completely useless unless you still running some kind of pentium 2 machine.

Guys. If you want to use bluetooth to connect devices, then leave Connected Devices Platform Service and Network Connection Broker on. Don't turn it off.

👍

funny how i don´t even care about my system and latencyMon showed better results after the first test, than your "after" screenshot xD

You ran the first test for a whole 39 minutes. You only ran the second test with the lower latency for 27 seconds.

After 39 minutes, it is normal for LatencyMon to fail once...

What a joke here

This worked for me right after the bios changes. The rest was additional for me

Good video. Comment for algorithm

After doing this the latancy is better BUT some games are just crashing after only 20-30 seconds after starting them? It was fine before? Any ideas?

Thank you so much Bro..!!!

nvidia low latency mode. U want to set this to ultra if u are GPU bound in games (95 percent utilization or higher. If u are not then set it off

😍

How u put the circle in the cursor?

You should also optimize your Windows. 0.02¢

🎉

Bro you should disable divices first at BIOS level. The. Only move to Device Manager.

Yo, can I do all the processes in the video on my gaming laptop? Just asking before doing it

You can see over 1h of pure trash here

Windows 8/10 need HPET on or you can suffer from weird clock issues.

oil snake at its best

Can this tricks fix cloud gaming latency like Nvidia Geforce Now?

NVCleanstall is much bether :)

Awesome video... just one thing should update all drivers and bios in the beginning not after you've change a million things then have to redo everything!

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.

I have an older system and most of these tips improved my system's latency except the interrupt affinity stuff. Maybe it only works well for newer systems? Or maybe cause my system only has 4 cores. Either way thank you for these tips and hope that your channel grows.

DON'T DO IT!

One thing that (almost) definitely solved my ableton issues is the nvidia driver thing. But also, as I have an MSI, I have msi center, in that app, you can set up a "gaming mode", I thought it was bullshit but I tried it anyway, two clicks and, everytime I launch Ableton, it pushes my processor to maximum performances, (more than i was able to do), and really puts it in priority. I was that close to sell that f*ckin computer. There is a real pb with todays pc, I can run Cyberpunk with RTX on no problems but no ableton without spending 2 months modifying the pc...

Hello in my case :
DPC before use your tweat : 0.70
DPC after 1.40
Seams like the DPC prob was coming from : bcdedit /set disabledynamictick yes
And the reverse doesn't work you should put : bcdedit /set disabledynamictick no
I go back to 0.70 DPC after

I don't have seems difference in the DPC with your stuff but i guess it's gonna gave more stable experience with the gaming ;)

Damn, this was a really good guide. It's kind of ridiculous with the marketing for Windows OS boasting that it is optimized for gaming but it is really not.

Well detailed video, nice.

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)

1 hour and 15 minutes damn 😭😭

snakeoil.

Settings affinities for individual USB devices will do nothing. In order to effectively bind your mouse or any other USB input to a core you need to bind the USB Host Controller itself, usually named USB eXtensible Host Controller. Just setting HID-compliant mouse is pure placebo. You can check if the affinities have been set properly by using latencymon or xperf by observing the usage of that core when shaking the mouse. Also it is ideal that you have your mouse does not share the same USB controller with other devices esp if it is 4khz above.

Will these optimizations work on my i3-4130 and gtx 1050 ti?
