Windows 10 Stuttering mvs91xx.sys

Hi everyone,

I just recently upgrade to windows 10. The first few weeks were really smooth, solved a few of my little annoyances from the old windows 7, but now I'm getting a stuttering problem. At first it showed up when I was playing Civ 6, so I had assumed it had something to do with the game, but now it's apparent it's happening to everything.

I searched a lot online and tried using Latencymon, the result returned was mvs91xx.sys is the one consistently causing this. Can anyone here advise me what this means? My computer 4 years old now, I am planning on upgrading once the new generation of CPU comes out, but that's still quite a while away.

Another thing I noticed is for some reason Latencymon is saying I have Windows 8 when in fact I have Windows 10 pro, don't know if that means anything.

Thanks in advance.

Thank you. I think I missed the most basic reason......my hard drive is almost full. I cleared some space and it has subsided. Marking as solved.
