I looked through your patches and I found the obviously needed alignment 
missing which made the code a little harder to read, as well as the some 
of the lines are over 80 characters long.
Can you please change it for better reading !
Do you know if there are any impact at all in d3d speed after shader 
support patch ?

Thank you,
Best Regards,
