Using CPU-direct USB ports for low latency? This guy made a tool.

CPU Direct USB Checker

It marks all my devices as direct to CPU, I don't know if that's true or if it's just messing with my PC because it's experimental or whatever.
But anyway, I'm glad it doesn't make me feel like I need to fix a problem that I doubt I would have noticed at all.

Nifty tool for VR headsets and dongle controllers.

Would this even benefit someone with a display that has 0.03ms latency?
I really feel it's helped me in Expedition 33. I am parrying everything so easily. Placebo, maybe?

Make sure your controller is directly plugged to the motherboards port and not to the case ports.

I have a 1ms display and I cant tell the difference.

 

[Crayon]

Never really thought about it. GPT says I can check with lspcsi. Seems to work.

Maybe I'll find one of those ports on the back and mark that for the capture card.

Wasn't the console had like 60-90ms input latency between pressing button and action start ? I dont think 0.1ms 1ms or even 5ms gonna do anything .

Nah Dirkedict, you're just that damn good pal

Also consider that usually, the manual of your motherboard will list the USB ports that are connected directly to the CPU.
For example, mine just states that the USB CPU ports are colored in red. Makes it much easier to find which ones are which.

yep this too!

Omg. I don't deserve to be part of this master race. How big of a difference are we talking about here?

 

[Unknown Soldier]

Most motherboard manuals have a useful block diagram that shows which USB ports are connected to the chipset and which are directly wired to the CPU

I haven't seen any actual testing which shows there's a difference though, transit time from chipset to CPU is measured in nanoseconds

USB ports and latency measurements - myths and reality | Practice | Page 2 | igor´sLAB

After the last article about system latency (NVIDIA Reflex & Boost vs. Radeon Boost and ZERO vs. AMD Anti-Lag), we should urgently discuss a few things about testing. So today we’re going to take a…

Here you can see there is zero real world latency difference between using CPU and chipset USB ports
