Tech Support Guy System Info Utility version
OS Version: Microsoft Windows 10 Home, 64 bit
Processor: AMD A6-6310 APU with AMD Radeon R4 Graphics, AMD64 Family 22 Model 48 Stepping 1
Processor Count: 4
RAM: 7113 Mb
Graphics Card: AMD Radeon(TM) R4 Graphics, 1024 Mb
Hard Drives: C: 698 GB (282 GB Free);
Motherboard: HP, 80CB
Antivirus: Windows Defender, Enabled and Updated

Problem in a nutshell:
When I install any version of the driver for my APU, my mouse lags.
I ran the drag-and-drop test in the HP Hardware Diagnostics Tool.
The mouse would drop what it was holding if I dragged something at a normal or quick speed.
The mouse did not drop what it was dragging if I moved it very slowly.

I've seen another guy post the same issue with the title, "Constant Mouse Lag" - however the thread is locked and yet unresolved. The response which was given was to check to see if it still lags with a USB mouse instead of the touchpad - which is a single step in the diagnostic process.
The question of whether it's just the USB mouse or the touchpad was one of the first things I ruled out - so, it's not that. The problem still remains.

I have narrowed it down to the problem being the device driver it's self not working properly on my specific machine or model.
In every article I see regarding Mouse Lag and AMD Graphics Drivers - it is a known issue, but only typically when you're running two monitors. There are a few solutions, but they don't apply to my situation because I am only running one monitor - the monitor which comes with my laptop.
When I uninstall the graphics driver, my mouse (both USB wired mouse and Touchpad) stop lagging - however when I uninstall the driver, my games (World of Warplanes; World of Warships, and other warfare simulators) run slow and make my laptop run hot.

Is there any way to figure out what's wrong? I'm stumped and I can't think of a solution.

Go to Control Panel > Device Manager. Find the touchpad driver, right click and Update. Do the same for the mouse driver.

I've done that. I am running with all updated drivers.
Go to the laptop's web site and see if they have driver updates. Sometimes the vendors do not give the latest drivers to MS to put onto Windows Update / Driver Update.
Yes, I've done that, too.
