So look at the objective marker on the wall. The FPS in game was locked to 60 via the recording software so every frame I saw was captured (Gsync). The video has been slowed down by 50% and you can see the stutter.
The main issue is this happens with all 3d ui elements when playing including player markers. So it can make the game appear to stutter more frequently than it actually does (stutter is still a major problem on its own as well) but the 3D hud stutter makes it hard to track players and predict their movement in a firefight, its distracting and just looks janky.
What happens is the location on the players HUD is not updated so the icons stay in that position until the next update. The big problem with this is when you “flick” your mouse for a 180 you can see icons just stuck their and in the wrong place in the view and can give you bad information. once it receives the update of the correct location it slowly moves back into position. (but at least smoothly)
