Assassin's Creed IV: Black Flag

What works

-Installation via Steam

-The Ubisoft launcher does not work since the last update two months ago (this is a problem that actually affects all ubisoft games). 
 To fix it, we need to use the "staging" wine version and chose at least Windows Vista version. 

What does not

-Ubisoft launcher if you do not use the wine staging version with Windows Vista or + as target Windows version in wine config.

-The game. I just show a black screen. No crash window.

Additional Comments

Installed using steam. The game launch the Ubisoft launcher that works ok (if using staging wine version). Once on click on start, the game seems to start but it only shows a blackscreen as it did in my last Test result (wine 1.9.20). However, if we take a look at the log, it seems that now the stubs for dx11 are trying to work (and not simply 'not implemented' as before): In the logs I can see plenty of: -fixme:d3d_shader:shader_sm4_read_instruction_modifier Unhandled modifier **** [...] -fixme:d3d11:shdr_handler Unhandled chunk "RDEF". -fixme:d3d11:shdr_handler Unhandled chunk "STAT".
