So my issue is odd. Occasionally the game will stutter during multiplayer matches on large maps but switching my video mode (between fullscreen and borderless) fixes it for the match, most of the time. I tried forcing Vsync through my control panel and that fixed it for smaller maps but not for large ones. Not sure if it has something to do with the increased player count or the fact that it’s a large map.
