--- Comment #1 from Pawel Stolowski pawel.stolowski@wp.pl 2009-10-11 14:31:23 --- I'm not sure if it helps with debugging the problem, but I've just installed d3dx9_*.dll files via winetricks and now the game works with correct speed. Winetricks created 'native' overrides for d3dx9_26.dll ... d3dx9_42.dll.
Please let me know what can I do (specific trace flags?) to spot the problem in builtin libraries.
