--- Comment #5 from Tobias Jakobi liquid.acid@gmx.net 2009-03-14 12:37:22 --- Created an attachment (id=19942) --> (http://bugs.winehq.org/attachment.cgi?id=19942) fixes expp handling in ARB mode
GLSL seems to be broken too. Also Stefan mentioned that this expp syntax was only allowed in d3d8 and gets "filtered" in d3d9, however I didn't find the code that does that.
Plus I need someone to run the testcase on a windows system.
