--- Comment #2 from DL dredgingthelake@gmail.com 2011-10-23 21:13:14 CDT --- I'm not sure if this is helpful but when starting pcsx2 with WINEDEBUG=warn+all and running a game with the latest version of GSDX, I get a heap of these messages:
warn:d3d:wined3d_device_draw_primitive Called without a valid vertex declaration set.
This message does not appear with the older (working) versions of gsdx.
