--- Comment #11 from Stefan Dösinger stefan@codeweavers.com 2013-06-16 08:11:01 CDT --- The fix itself is fairly simple and isolated to the IDirect3DDevice2 and IDirect3DDevice3 interfaces. Writing comprehensive tests will take a day or two though. (I've Device2 done now, that needs porting to Device3 and Device7, and some additional tests in those versions to make sure that D3DFVF_RESERVED doesn't influence lighting)
