Vsync causes stuttering in packaged game

Hi!

My problem is that, when I activate vsync in my game, it results in some stuttering. Fps fluctuates a lot even locked to the screen Hz and it seems to be the problem, because when if I cap the FPS to something like 142 or 143 ( I’m using a 144hz screen) frame rate is more stable and stuttering is less visible. If i cap it to 144 is still visible.

I tried to disable smooth frame rate just in case but nothing happens.

When I disable Vsync in the same place and lock my frame rate to 144 for example, it results on screen tearing but the movement seems to be a way more smooth.

I want to know if there’s a way to make Vsync more stable and smooth or if this is a common issue.

Thank u!
