I noticed this a few days ago, when I had some issues, and disabled my overclock, and then re-enabled it.
At stock speeds ("UEFI Defaults"), Windows 10 is fast and smooth, and my mouse movements are smooth.
If I set freq to 3800, voltage to 1.325V, DRAM to XMP Profile 1, DRAM speed to 2400, and disabled "Global C-States" (a Ryzen overclocking recommendation from another user early on), and then boot Windows 10 - I get mouse lag.
Like, I can move the mouse, and there's a slight delay, and when I circle the mouse, it moves smoothly, then lags, then moves smoothly, then lags. It's the weirdest thing.
And I thought that last time I had it overclocked to 3.80Ghz (3800 setting), that I didn't have any of these issues.
Please help.
Thanks!
I didn't find the right solution from the Internet.
