Something feels bad on my eyes

There is a very fine stutter when there are many things on the screen. There are scenarios that when there are no enemies it looks very smooth, and in the same scenario when there are enemies it feels bad to look at. I don’t know if it’s the effects, or a fine stutter or something else, the fps are not. It’s something that wastes my energy a lot when I play

Im playing with a 1080, i7 8700k, 32 ram, and Gsync, and it is far to be smooth to me.

Is it screen tearing? Jacked edges? FPS drops?

not to tearing because i had Gsync, and not fps drops because switch to dx12, Jacked Edges i dont know what is it

sorry, JAGGED edges - diagonal lines that SHOULD be straight but look “like a staircase”
