When I start a program on my PC, the mouse pointer always stops for a short time, although the PC is enough to start with, it has an i5 and a geforce 960, so it's not about performance. Only Windows Defender is activated in the autostart. And my laptop is much weaker and doesn't have the mouse problem.
Maybe the program on your computer is acting a bit strange and suddenly loads so much data that the mouse pointer freezes for a short time. Most of the time I really have it on my computer when too much data at once gets too fast for us. It is not so important what kind of processor or graphics card your computer has, but the speed of your hard drive. If your hard drive is not that fast, even an awesome graphics card is of little use to you
I know that the graphics card doesn't make the PC faster. It's just supposed to show that he's more of a gaming pc. Drive C is an SSD from Samsung's 850 Evo, I can't imagine it's slow.
