--- Comment #3 from Jörg Höhle hoehle@users.sourceforge.net 2009-09-14 11:45:15 --- The switch to Shader Model 2.0 in Wine past wine-1.1.24 makes things even worse. Ankh2 is unplayable since, as there are too many visual glitches in the scenes, the menu and the intro, everything is extremely dark, except for the fonts, while a continuous stream of GL_INVALID_OPERATION glDrawElements @ drawprim.c; scrolls by.
