Pygame пропускает фреймы

Question

Я новичок в pygame и начал делать локальный многопользовательский 2D космический шутер, чтобы попробовать

Я реализовал много вещей, но есть фундаментальная проблема с pygame просто пропускать обновления кадров время от времени

Например, если вы поместите курсор в любом месте и двигаетесь вокруг него, периодически корабль будет просто прыгать

Это НЕ УЖАСНО, но было бы здорово, если бы там было легким исправлением / объяснением

Вот код устранения неполадок:

#Temporary Troubleshoot
##Only movement and aiming from main code
