Yes, Gamestudio is "optimized for the latest Graphics card". Still, beginners can easily manage to produce a game running with 1 fps no matter how good the graphics card is.

As you can see from the examples, A7 itself has no problems to handle 50,000 or 100,000 entities - but drawing them is up to the graphics card. When you have frame rate problems, first look in the manual for the frame rate hints before you buy a faster card.
