Tournaments in Shibuya train station and the Igris boss rush map are super irritating to play after 10-15 waves.
Fps starts normally, and the starts to drop every wave as more enemies come on the map. It then settles at 10-20 fps.
You can't walk without lag to delete and replace units, and it gets super laggy.
And most people do tournaments with visual effects off, so it won't hurt to decrease the overall graphics/visuals.
Obv you can disable cosmetics on your own, but this is a qol suggestion. It can improve the overall experience and doesn't hinder the players from unequipping and equipping cosmetics for a 15 min game.
