I hope this is in the correct section.
I am having constant stuttering issues. This is most evident when I play games on my laptop, the game would just momentarily freeze and then just continue. When not playing a game, it's less obvious. For example, I'd right click on the desktop and the menu takes that little bit longer to load up. Or when I am moving my mouse down a list of folders and there is a 'soft highlight' of each folder as I move down, but suddenly the mouse would continue to move but the 'blue soft highlight' wouldn't follow. The 'soft highlight' would then jump to where my mouse is, without highlight the folders I moved my mouse over.Sorry if this made no sense, it's the best way I can explain stutters when not in a game.
I followed the guide here:https://www.sysnative.com/forums/wi...ues-with-wpa-windows-windows-vista-7-8-a.html
I am posting an image of the xperf DPC summary table:
As you can see, the WDF01000.sys has the highest usage. But I looked at this table: Driver Reference Table
and it says that it's a Windows System Driver. Does this mean there is nothing I can do?
I have gone through various latency checkers and have gone through many 'disabling' and 'uninstallations' of drivers that I know aren't absolutely key to the computer running.
I used the tool in this screenshot:
and disabled/uninstalled drivers/devices:
1. I have disabled the sound devices (under Audio inputs and outputs in Device Manager)
2. Completely uninstalled my graphics drivers (Nvidia)
3. Disabled my wireless device
In a hope a to 'narrow' down any issues. I couldn't find anything and nothing has changed with the stuttering.
My computer is a Lenovo Ideapad Y500.
I would be grateful if anyone can help!
