Doubt about chipset driver and mouse

[Satan1cB1blie]

I've always had a feeling that motherboard chipset drivers influence the accuracy of a mouse gamer.

Anyone who understands the subject could tell me if this makes sense or it's placebo. I'm wrong?

 

If anyone has any questions can do tests I believe they will notice difference mainly with low dpi and sensitivity. 

 

Both with AMD and Intel the same thing happens for me. With drivers different versions and dates

Chipset are NULL drivers. They don't do anything.

The USB drivers will directly impact the mouse though. Different driver versions can be Line-Based or MSI-based for CPU interrupts, with different settings like message limits, and interrupt affinities.

Other drivers can indirectly affect the mouse as well, due to potential IRQ stacking with the USB controller, and their interrupts taking away valuable CPU time needed by the mouse, which can make polling a little unstable.

So is it totally placebo? I'm wrong. Thanks for answering.
