Using the latest beta (r3881) of GSDx, I can't get okami to work right. In D3D9 nor D3D10 hardware mode, when you go into brush mode it is supposed to tint the screen brown, display a brush and a black dot underneath it, and do a little "flip" animation. Only thing I get is the black dot.
In software mode on either one I get a correct brush screen... but the rest of the game has an odd "blur" and "bloom" effects on everything, and the performance is unplayable.
I tried zeroGS just for comparison, it does the brush screen correctly but everything else in the game is just a black screen with only the ink meter and health meter showing up
(my guess it incorrectly makes a solid black background instead of an alpha transparency layer, thus covering the visuals underneath).
And I tried different versions of PCSX2, including compiling r4510 myself; results were identical in all of them suggesting its GSDx. Oh, no speed hacks were on.
I tried compiling latest GSDx myself, build was successful but PCSX says its not a valid DLL (apparently this happens to others with current ver, even if they use VS2008, I used VS2010 btw)
So anyways, all of those info bits combined lead me to believe there is some sort of bug with GSDx hardware mode which prevents that portion of okami from working correctly.
