Really happy to see that the knowledge of proper input lag testing is spreading little by little. Great article!

Also, I'm sorry you experienced the wrath of frustrated gamers, I had my fair share of that.

Last week, I received a small care package from @noodalls with a kit for building a lag tester!
I whipped up some Python scripts to automate testing and have generated tons of new findings (including the one above).

Refer to the link for full details.

@jav1ts @thefleecer @Arlieth @HiFightTH @fubarduck @GelatinLab When I made my script to reliably send inputs, I had to make it as part of the gamepad API injection to make it consistent. Just sleeping 16ms had way too many flaky results.

I didnt look in details the quoted post but I feel we are in this territory.

@jav1ts @thefleecer @Arlieth @HiFightTH @fubarduck @GelatinLab Connecting back to this platform and getting 20+ notifs already 😆?

I havent dug into it lately, however what I can tell is that input parsing happens one per game-tick (60 times/s) and the exact poll timing cant be trusted at the ms. Nothing new afaics.

@MDZ_jimmY I would like to do that eventually. I have people I want to follow there so I created something there. Didnt think much more ahead.

In any case it wont change much considering the amount of tweets I've sent over the last months/years.

Seems when I updated the site it made the URL wrong.

This will be a site that contains links to my results as well as a description of what' going on.

@Ragnarork Would have strongly disagreed. But then I saw the definition in french is "Fidélité à tenir parole, à faire honneur à ses engagements". While I see in english is "Faithfulness or devotion to some person, cause or nation" or similar. I firmly adopt the former and reject the latter

[Loïc *WydD* Petit @WydD]

@olafurw Holy s**t! I'm catching up with all of them of while now! Good to see you on this!

@SmokeMonsterTWI Does the chatpad work? It doesn't on modern drivers that's for sure and it is marked as not working on PC in documentations.

@Cocodwor Woooooh lucky!

@knkmotoh I tried tapping directly to the CPU or via the chipset same thing: the negotiated speed is FullSpeed. However, weirdly enough, I had 2ms also by picking the 2.0 port on the motherboard (??).

I feel it's windows usb driver picking the "wrong" value for the negotiated speed 🤷

[Loïc *WydD* Petit @WydD]

Question to usb engineers. I have a USB 2.0/FullSpeed gamepad with a bInterval = 5 endpoint.

On windows, if I plug it to a SuperSpeed port, it has a 2ms polling rate. If I plug it to an old HighSpeed port, it has a 4ms polling rate.

Is it a bug?

[Loïc *WydD* Petit @WydD]

The spec says that if it operates at HighSpeed it uses 16 microframes = 2ms. So I think that's where it comes from. However, USB Tree View tells me that both work at FullSpeed.
