Почему WPF XAML работает медленно во время выполнения?

Question

Я создал проект, используя powerbuilder.net 12.5 и WPF.

Без каких-либо эффектов и анимации. Everthings работает быстро и хорошо. До тех пор, пока я не добавил некоторые эффекты и анимацию, он теперь работает очень медленно, особенно во время выполнения.

Как мне это решить? Или есть способ сжать/оптимизировать мой код? Благодарю.

Вот мой код XAML

Для моего личного опыта разработки XAML необходимо, чтобы компьютер предпочтительно снабжен специальной видеокарте. Однако, много раз даже в очень старом компьютере с Windows XP Чтобы разжижать программы я сделал установки обновления Direct X библиотеки

XAML основан на Directx
