Pardon my ignorance, but why can't a 3d object (in theory) be running at 50?

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

And yes, stats is the main thing here. I don't think it should be enabled by default. I would love do to some performance testing SDL1 vs. SDL2 on different platforms (and different SDL drivers)

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)
