Question FPS stuttering in games and I don't know why ?

The past few months, some of the games i play have been experiencing heavy fps stuttering issues. It seems to be mostly games that are GPU-heavy.

The stuttering is very consistent and repeats about every half second. For example:

Helldivers 2: on ultra settings i get about 120fps. Every second it goes 120/80/120/80/120/80/120 very quickly. Quick enough to notice a skip in gameplay.

One thing to note (not sure if it matters) is that the GPU time also jumps with the fps stuttering. So as my FPS drops, my GPU timer jumps to a higher ms.

If my fps drops from 120/80, my GPU time goes from 9.0ms to 12.0ms at the same rate as the FPS, which leads me to think it could be a GPU issue.

I have:
  • Installed all current drivers
  • Tested my RAM sticks
  • Swapped installations on different drives
  • Reinstalled Windows

Any help would be sufficient. Suggestions on what it could be, what to do, etc.

Thanks!

Can you confirm the model of the PSU as there are good 850w PSUs and there are not so good ones.

What resolution are you playing at?

Does dropping the quality settings in game make any difference to the frame rate / consistency?

What other games does this effect and do some games run fine? From looking online there are a significant amount of posts regarding Helldivers and choppy framerates is all.

Sorry for a lot of questions but I think a few more bits need to be understood.
