All the games run very slow on my machine even though I have a modern graphics card.
One of the recent NVidia drivers had a problem which causes Game Maker games to run really slow.

To solve the problem download and install the newest drivers from the NVidia site: http://www.nvidia.com
Ich hoffe, das löst dein Problem.
