My mouse and keyboard is connected via usb 2.0 active extension cable 5 meter , between cable and peripherals i have simple hub with 4 usb ports , just 2 are connected .
I have big lags on both mouse and keyboard on PC but when i do the same on my laptop they work normal ?
It happens already on my second pc which i have bought recently.

Make and model USB hub?

Does the USB hub have its' own power source?

What other USB peripherals are connected to the host PC and hub?

You can easily find other similar links.
To hub and generally for the whole pc i have just mouse and keyboard. I don't think if it can somehow affect, I have HDMI extension cable 5 meter connected to my GPU.
USB Hub is without its own power source.
I tried to connect just mouse or keyboard without hub direct to extension cable, same effect.
This is my cable:

Might be the problem that cable 5 meter and my mouse cable has like 90 cm adition lenght?

Could be the length but I would also consider the overall quality of the extension cable as a concern.

I see nothing in the Gembird cable specs that supports it being able to go 90 feet / 30 meters.
Strange that i have tried to connect to my old pc and it works fine. My new pc contains GPU and SSD from my old Athlon.

Strange indeed.

However, I do not find it surprising that it works on an older pc but not on a newer pc.

Just some threshold difference between the two systems.....

If possible try a hub that uses its' own power source.
