Mouse, keyboard, peripherals, spiking numbers in the menu, is it normal, should I be worried?

[___masrhmallow___]

I wonder if its normal the numbers spike as I move the cursor, and return to normal as I iddle the mouse.

Which could be the cause of this?

Specifications:
Intel i7-11800H
Windows 11
Acer Nitro AN517
VBS disabled

Behavior:
1. I have two monitors, the laptop one and a large one connected with HDMI.
The spike is higher when the mouse moves on the main screen, and is less higher when moving it in the secondary screen, yet in both the numbers spike while mouse movement.
Although if I disconnect the large monitor, the laptop monitor still spikes anyway.

2. If I press Turn Off on the main tab, the numbers still spike anyway, even if TS is disabled.

3. If I type with the keyboard, the numbers spike too, same as it spikes when I move the mouse, its not just the mouse peripheral.

This is normal unfortunately. I think some programmers writing mouse and keyboard drivers must think that CPUs still run at 10 MHz and not at 5000 MHz like most computers can run at. They seem to over sample any mouse movements millions or more like hundreds of millions of times per second.

Moving a mouse around randomly on the screen should not need to put that big of a load on a modern CPU. ThrottleStop does a fantastic job tracking CPU usage. Maybe driver developers should stop using the same code that they were using 40 years ago. If they used the ThrottleStop C0% data, they would realize that it is time to update their inefficient driver code.

Did you install a manufacturer's mouse driver and their software?

even if TS is disabled

TS is not the problem. TS is extremely efficient. It does more while using fewer CPU cycles compared to any of its competitors.

There is likely nothing you can do about the inefficient software you have found. Sad when you need to dedicate a core running at almost 5 GHz just to manage a mouse and keyboard.

For the keyboard no, its the default driver for the laptop.

For the mouse yes, its a Swiftpoint Z with its software, driver and firmware from the manufacturer. Its a very expensive mouse, its quite surprising for me that they are using archaic mouse driver even for such elevated price devices.

Is the large consumption a problem for everyones drivers, or it depends on the manufacturer?

Is the large consumption a problem for everyone's drivers, or it depends on the manufacturer?

I think excessive CPU usage is a common problem for all mouse drivers including the default one from Microsoft.

it depends on the manufacturer?

Some seem worse than others. Some are bad and some are really bad.

Poorly written and inefficient software is just my personal rant. I used to use an Amiga computer 30+ years ago. It used a single core 7 MHz processor. That was more than enough computing power for smooth mouse movement. Fast forward to 2023 and now just moving the mouse around the screen on a 5000 MHz CPU causes the C0% to jump up to 10% on one core. I think there is room for improvement but no one has time to write efficient software.

When my computer is idle at the desktop, look at how low the C0% is.
Average C0% = 0.04

When properly setup, all of Windows 10 including ThrottleStop take up next to nothing for CPU cycles.

I think a properly written mouse driver should not need to load the CPU as much as it does. The only thing I can think of is the mouse software must be sampling for any movement about 100,000,000 times per second. I think you can have a smooth and responsive mouse without having to check for mouse movement that often. Go complain to Swiftpoint and they will probably tell you to buy a faster computer. More cores and more MHz is the solution for everything.
