That is great news :-)

It confirms my assumption that the SDL - Mac implementation causes the 
problem when too many (unnecessary) SDL calls are made. I did 
drastically reduce the number of calls in the Enigma display part for 
multiple actor levels in the trunk version.

Sidney could you please start the trunk version on both Macs with the 
option "--showfps". Please try to play "Bright Dots", "Deserted Island" 
and "Wolf Among Sheep" (Development Group, Experimental Levelpack) on 
both Macs with approximatly the same marble speed and report the average 
fps values shown on the screen. I would like to know if there is still a 
critical difference in both Macs.

David did report to me:

@Sidney - can you please give me access to your trunk compilation as I 
would like it to be tested by David, Ale and Taztunes, too.

Thanks,

Ronald
