Yes of course I tried it. With RebelSDL it is a bit faster. 5 pages per frame.
Again, I have this bottleneck only on Amiga (OS4/MOS), the win target runs fast and smooth without any plugins.

The other problem is that the large difference between frames. With the fastest RebelSDL it is oscillating between 2 and 5 pages per frame. With GLGalore it is between 1 to 3. It is hard to make it smooth if I want to do something between frames.

In the meantime tried to make the same test with LÖVE game engine (love2d.org). It has an sdl 1.2 OS4 port by Bszili. I think it runs on minigl too, and using lua as the language, so the comparison is reasonable.
The result is 1 page per frame.

Looks like Hollywood's performance is quite good for a high level language, but what is the reason of the large swing? I know that a multitasking environment can not guarantee equal cycles for a task. Is there anything that I can do with this?
