Getting a lot of feedback about the testing methodology, if someone wants to recommend me the best ps2 mouse and best ps2 keyboard then we can redo the tests on a 240hz monitor and 1000 fps, that way can see the differences as they come in.

1-2ms ps2 5ms usb

That vintage intro! Every time you suprise me with those little things, keep it up Bryan!

From a production-value POV, one of your best videos so far, no doubt. Low-key topic but very enjoyable to watch.

Another thing about PS/2 mouse is also extremely low CPU usage. On modern system you won't even notice it but i plugged 1000hz usb mouse to pentium 4 single core machine running winXP and while moving mouse on the desktop with no program running the cpu went straight to 100% usage meanwhile dragging PS/2 mouse around the desktop the cpu was chilling at 1-2% usage. I even tried putting the usb mouse to 125hz polling rate and while dragging the mouse around cpu was still at like 20%+ usage

Good stuff man. I love this kind of edge case testing. The history lesson was nice too.

Hey Bryn keep up with the good work that you are doing, you got good stuff going on. Specially using the old retro hardware with today's newer pc hardware

Please do another awesome video! I really enjoyed, thank you.

Hmm. Interesting Brian. Oh yeah, love the mustakes at the end of your video's. Always fun to watch

Watch out Logan might taze it!!!

That a PS2 mouse holds up after nearly 2 decades of tech improvements is amazing. What other tech can say that?

Never knew all of that stuff about PS/2; I enjoyed that small blurb about them a lot!

Thanks Brian, I've been having this argument for years. I used ps/2 mice up until 2 years ago always felt they were a little faster or just as fast but couldn't prove it.

Thanks for this overview/history/comparison/etc. I'm glad to know that the USB interface doesn't affect latency, at least in the testing performed here. I've got a cheap USB laser mouse from GE that feels incredibly fast and responsive. And it bugs me, because I recently purchased a Logitech G703 wireless mouse, which feels sluggish in comparison. I thought that modern wireless mice were supposed to be "on par" with wired mice! Maybe I need to adjust polling rates or something...

Optical mouse were available to the public much earlier I had one (Golden Image) for the Amiga A1200 in the early 90s and the PC had them since the mid 80s. They were expensive and worked with their mouse pad that had a pattern on them.

Good video Bryan LOL at the out takes

Nice vid. When is your SR-2 build coming?

I know it is not your channel's concept, but do you have some retro hardware like old commodores, Atari computers?

Oddly I ran into a weird issue where a third party RDP provider called paperspace had a bug in it's native app, a ps/2 keyboard and mouse was the only instant fix as the app took out all my USB devices, assumingly a weird driver quirk. Only other thing I could do was restore win10 from a previous update. Was super glad to have kept an old pair.

I owned a 3 button mouse systems pc mouse in the mid 80's that was laser optical and used a special mouse pad. It was a serial mouse but you could buy an adapter to convert it to PS2. For its time it was probably the best mouse you could buy for things like CAD work.

Cool Video. Thanks! PS2 Mouse and Keyboard is sometimes good for troubleshooting old PCs.

FM-84 - Never Stop (feat. Ollie Wride) 0:14 1:13 this is the first time i hear this song wow , i love your taste of songs and music , thank you good video and info keep it up

I myself use a old Hp Workstation Ps2 Keyboard and i really do like it, it is really solid, has great response times and has a almost mechanical feeling. I love it

Great Videoa s always Tech Yes City. That PS2 mouse you had there is a run of the mill Logitech mouse most of them would just have a sticker on the bottom that would come off after a short while. That model of mouse was never sold in a retail box it was sold as a OEM mouse that came in a plastic bag. Even back in the mid 2000's I think you could buy them new for like $12 bucks CAD but they worked pretty well for the money you spent on them.

full rollover is hella cool actually, my keyboard came with an adapter and i was wondering if i should use it, now i know, thanks

I love that outro :D

You also need to keep in mind that the game it self can add input lag depending on how it was optimized. Non-3D games (or non FPS games) often have lower input lag since the game is just much more simple to run. Also the speed of the PC is important. I'm sure the input lag is higher on a i7 2700k Sandy Bridge, vs a i7 8700k Coffee Lake. Or even between an i3 to an i7 (i9?). There's a LOT more to input lag than just a PS/2 or USB port. Does it even matter if the mouse supports USB 1.1, 2.0, or even 3.0? What about all the iterations of the PS/2 port, if any? Also does it really matter if you plug in a PS/2 keyboard to the Purple port, what happens when you put it into the teal port meant for the mouse? Does the PC or the OS even care?

But does it track your movements well? Like in low sensitivity gaming and stuff, as some mice i've tried before just cut out when i move them too fast

Would like to see a performance comparison between USB, PS2 and Serial mice.

Yeah, I usually use USB, though my keyboard uses it through an adapter. I do enjoy that I can use my Dell Black Alps switched PS/2 keyboard from 1991 (27 years old!) on my Z97 PC. :) I do prefer my Logitech MX508 or whatever it's called over all other mice.

Awesome vid. You answered some questions regarding ps/2 mice...its very informative in todays society because they are of some use. In other words its a tech item still relevant today.

You should've used the song We Built This City by Starship for that 80's reference.

I found a PS/2 to Usb adapter in my gearbox. So my quesiton is, should I use my USB gaming mouse with this adapter on my mainboard to have one more USB slot. Does it work as fast as USB slot itself?

Hey Bryan Thanks I have a new in the box PS/2 keyboard and mouse from back in the day I got for a Dollar and it mechanical just haven't tried it out yet. Let you know when I do. --- Also First 65 or Older

What about the sensors though? How much variance and lag are in the older ps2 mice?

Testing methods look a little bit inaccurate to me. Did you use a slow motion camera? Thanks for all the good content, I always love watching your videos!

my mechanical keyboard freezes every bios I've ever touch, old ones. do you think usb to ps2 converter can fix it? because I'm annoyed switching keyboard for bios --"

Interesting test, I liked this video. I wonder if maybe the difference is too small to detect on a 100fps recording. If you could find a 240hz monitor, and use 240fps recording on a Galaxy S7 or something, maybe there'd actually be a tiny difference.

You should do a video on the LGA1366 workstations like the Lenovo S20, The Dell Precision T3/5500, and HP Z400

but did you test the input lag while the system is under high stress?

I have a green PS/2 adapter for a mouse. Will it work on a keyboard?

Is it that hard to make a newer hardware port so we dont have just one option thats usb with high poll rates which increases cpu interrups and takes more power? Usb advantage is hot swap automatic driver install and supporting any function, why cant we have a hardware port that does that too.

I remember the 1000hz SoftMod to PS2 made such a difference on HL1 / Quake 2 and 3

Hey Brian in the video you had a laptop that I previously had the acer aspire v15 nitro black edition I was wondering if the 960M is powerful enough for you and would you be doing a full review on it there was a few problems with it for me for example the battery life was really bad and you couldn’t game on it unless you had it plugged in.

What is that cool retro song though - I have to know cause it will fit as a custom soundtrack while playing MGSVTPP :v

PS/2 is actually better because its got its own IRQ. As soon as you get three devices on a USB it automatically is worse from an interrupt standpoint, maybe not throughput.

PS2 mice are fairly old, upgrade to the latest PS4 Pro mice 😉

really interesting. how about those much older serial/com/rs232 port mouse? are they more direct to hardware?

For me the most important feature of the mouse is not the type of connector but the number of _real_ buttons. I bought what I suspect may be the world's last ever proper three button mouse (i.e. no scroll wheel) a couple of years ago. Yes, scroll wheels also double as buttons, but they don't feel anything like a real button, and they have a habit of scrolling instead of clicking at just the wrong moment. This is especially important in Linux, as middle-click to paste is standard in *nix systems. I also tend to configure the middle button to jump in fps games, and scroll wheel mice are a nightmare in that scenario.

i still keep a ps2 mouse and keyboard in storage for the times i get old mobos that dont accept usb ones till an OS is installed

I wish it was the 80s. I wouldn't exist

Also the PS/2 have it own communication port, like USB is a shared port. So with many USB ports hustling of the banwith can get more reaction time.

I like the simple design of mice especially the zowie EK1s

Nice video, what about the Logitech G402 with the "fusion engine" ??

Microsoft Wheel Mouse Optical 1.1a still sitting around here. Not as my main driver, but working fine after all these years. And supports both ports, so will run on any computer be it 20 year old or just a week. There are drivers and a software suite, but it is fully functional without it, so it runs on any system.

My setup bench uses ps2 keyboards. Sometimes I will grab the mouse and go with it for installing Windows. Used one today for moms new Ryzen 2200g build. Still relevant and useful. I see no need to buy a new one just for this purpose. Cheers mate!

i stuck with ps2 mouse and keyboard for a long time after USB peripherals took off, i think it was around 2008 i finally switched to a USB mouse, but was only 2014 when i sort of left PS2 keyboard, i used the same PS2 keyboard (that i have been using since 2003) with an adaptor to plug it into a USB port, and was just 10 months ago i finally plugged in my USB Corsair K40 keyboard that i bought in 2015 :D

Never Stop!!! By Fm-84! Awesome! Saw them live in San Fran!

Does a USB to PS/2 converter help with latency with a regular USB mouse and/or keyboard?

If I have a G502 and have keyboard key mappings setup on my mouse can I use a ps/2 adapter or would the key mappings not work?

Could you test different budget mice under 50$ and show slow motion of the latency.

I always felt like the way people chose peripherals back in the day before everything was branded "gaming" still holds up today. The best mouse/keyboard is the one that suits YOU well and that YOU are used to. I wonder how high up one would have to go in competitive gaming to actually have a significant advantage from changing to more costly gear. Just because it is more expensive or newer doesn't necessarily make for a better experience, just look at the hype around the IBM model M ...it's almost 35 years old.

60ms is huge! does this explain why the mouse cursor feels disconnected ?

What about keyboards. Is the same latency as usb?

I have been wanting to do a video like this but with a keyboard for ages but lack the high speed equipment to do it

Man thanks. Might you propose a new test so to updates news useful for this comparison?

Since it is directly controlled by the cpu, that would imply an unstable overclock.

We want more of these videos

PS2 vs logitech "faster than wired"?

What about USB to PS/2 adapter on G302 for example? Do you benefit from it, or it adds input lag? :)

You mentioned gamers could stil use these, what dpi do these mouse have? 400-600?

when you do the keyboard ps2 review can use the bloody keyboards with light strike. they say they have the latest keyboard because of their switches would be interesting to see.

In Ozzy Bogan world it's always the 80s, lol the good old days of using my IBM XT mmm 640k RAM so Baller .

Can you test the input lag of popular USB mice like the G502 please?

Hmmm interesting, particularly about the USB lockout.

I still use my G3 mouse, I still haven't seen a mouse that has the same arrangement of buttons in uni-hand format. I always hold my mouse wit my fingertips, I don't want my palm touching, anyone else like this?

Problem is it depeneds more on sensor and mouse firmware. One mouse can have lag on its own(inherent to implementation of reading sensor and translating to data sent to operating system or too heavy jitter correction, especially prevelent in high dpi mice) And in experience, it has nothing to do with polling or interrupt if a mouse is responsive or not. PS/2 200Hz can feel smoother in some games, compared to 125hz USB, OR the other way around depending on amount of FPS you get and how the tears then splice the screen on panning and tracking movements. Also a fire animation is not any way of testing really, since its not high priority on a pipeline of events in game. From aweful CPL "mousefix", logitech mouseware filters to doubling count on win9x in some games, its WAY more complicated, generally more down to the game processing mouse input like windows xp directinput, no framepacing, smoothing or nvidia anti-stutter bs. "lower"-dpi mouse with "low-grade" sensors that skips at higher DPI is prefered, should even skip here and there at 1000dpi seems to be a sweet spot for most responsive mice. None existant or no implementation of smoothing. But its much bigger, finding sweetspot with monitor hz, mouse hz and fps to manage the tearing to what fools your eyes the best. Resolution and "pixel skipping"-correlation with DPI matters too with perception TL;DR 2000dpi MAX sensor mouse, no firmware bullshit. 500hz USB or 200hz ps/2 depending on how you match panning tearing vary from game to game

Is that CM Masterkeys your daily driver? I love mine

I've often run into bootable diagnostic and antivirus tools that don't seem to support, or may disable USB ports--so keep a PS/2 mouse and keyboard on hand.

You should try the g303, pretty much the same mouse, just an upgraded sensor

I have the msi ds100 mouse it's a really light mouse and I am always finger tip gripping i've had some heavy mice in the past that was hard to push and maneuver around but this ones great. *Licks paw*

yo brian is china capture card is good? an idea for your next video mate 😁

Test in a good CRT monitor, like the Samsung 997DF and don't forget to install the monitor drivers, it can go at 120 Hz without response time and display lag

I always thought it was weird when my new motherboard included the ps2 port. This explaons it. 😮

Is there any difference in performance on gaming mice when using a usb to ps/2 adapter?

Where's the PS/2 Keyboard video?

They might be responsive but I doubt they track accurately and at high speeds like current top mice.

When I used PS/2 Mice back in the day you could get utilities to change(Increase) the polling rate on the PS/2 port. Ball mice also had some advantages. EG You could swipe and lift the mouse, the ball would keep spinning while mouse was in the air.

I always use a ps/2 keyboard, even in 2018.

I have no other problem with PS/2 keyboards / mice but the fact if you have do disconnect one, you need to reboot to make it work again. actually, in case of keyboards, i would actually prefer native PS/2, as the connector IMO, is "more securely connected" and using one leaves one USB free. That being said, last PS/2 MOUSE i had was some razer ball mouse i had circa 2002 and really didnt even use.

PS/2 mice were great in the way these didn't look like some odd spaceship that tries to fit in your palm. Also there's no fuzziness with drivers as you said. However, there were also plenty that just didn't turn out well for gaming. Please keep the outtakes.

Using logitech G Pro, and love it, no lag at all, 1000Hz polling rate is fantastic :)

on top of my previous comment, it sucks you couldn't enjoy the fk2, it's my favorite mouse right now. But i might get a finalmouse soon

You didn't mention your polling rate with the newer mice. Did you just leave them at 124Hz or up them to 500-1000Hz? Whenever the 'Logitech Gaming Software' silently crashes on my system, I can instantly tell, as the mouse reverts to 124Hz polling and becomes both jerky and laggy. It'll only make a difference of around 6-7ms, but lag is cumulative and that 6-7ms can be the difference between a responsive and unresponsive system. I actually got my mother a gaming mouse - she's never gamed in her life - specifically because the IPS panel on her laptop is quite laggy, and a g300s performs much better than the MX Anywhere I had gotten her previously.

Should've looked into how well it resolved motion resolution.

oh yeah i love this video, bring me back to old tech yes city used to be xD

Is there any way you could measure delay without a camera? It seems a bit lacking considering that you’re only recording at 100 fps. I know the monitor is running at 100 fps as well, but we don’t have any guarantee that that’s matched. Milliseconds are what matter here, and you’re recording a frame every 10 ms. It would just be great if you could find a way to measure delay through the system instead, for (relatively) absolute accuracy. Your video is the only video I’ve seen so far where someone has tried this, and an improved/updated review would be greatly appreciated.

how can you add buttons to a mouse?

My friend bought a brand new Acer prebuilt PC in 2013 and it come with a PS/2 mouse and keyboard

Does it come down to response time on monitor?
