I have fixed some bugs:
-when the black pawn reached the end of table, it turned into white puppet
-fixed crash when setting rendering resolution
-fixed some stability problems when updating the scene on multiple threads
the game eats 1.5 gbyte of ram, so you should be able to run it on 2 gbyte ram too if you want, however, if you want to use firefox and other softwares too that needs ram, that would be not ergonomic. when you use suse linux with skype, firefox, pidgin, and using the chess with it on 4 gbyte ram, the system sometimes starts to swap some, wich i find very ugly, so i suggest to have at least 6 gbyte of ram for the ergonomic operation.
