Yes it can, it all depends on its complexity, number of faces, size, ... 
Some demos had 50 FPS 3D, but most games are not.

Then I'm afraid we don't talk about the same thing. What you want is to 
measure the performance of Hatari itself, ie how many time takes Hatari 
to render a frame (I saw your discusson on AF about R-PI)

This is a different issue ; basically, if Hatari is too slow to render 
50 FPS, some frames could be skipped.
To see this, you might want to enable frame skipping in Hatari, which 
will print in the status bar how many frames were skipped (due to too 
slow emulation).

Eero might have more insight on this and how to interpret it (IIRC he 
worked on the frame skipping code)
