Сделал ещё одну очевидную оптимизацию - кэширование матриц препятствий, результат превзошёл всё ожидания. 300 объектов - плавные 60 фпс, 500 объектов - 60 фпс с микрофризами. Для масштабов игры этого уже более чем достаточно. Теперь следует добиться такого же для более слабых машин, надо выбрать минимальные системные требования.
