- Eliminate the useless check for cpu modifications option from efb to ram as it must be enabled always
- use constant names in dx11 for buffer length calculation instead to simplify code reading
- implemented scaled efb copy in opengl, still bugy in some games, the option is not in the gui but will add it when it works perfect
- Change the depth calculation behavior:
if the game use z textures is exactly the same as before.
if the game do not use z texture calculate z values in the vertex shader. the advantage id this approach is that early z culling is applied,
improving fill rate. this mus speed up things, even with ssaa and msaa enabled.
please test for regression and enjoy.
