Gregory Hainaut 92553add8e gsdx-ogl: accurate date regression. Bad interaction between depth & DATE
In the DATE42 algo, first pass must find the primitive that write the
bad alpha value. If depth test is fail, alpha value won't be written therefore
you mustn't keep the primitive id.

In theory to ensure 100% correctness, depth would need to be fully executed
(currently depth write is disabled). However it requires to copy the depth buffer.
It is likely bad for the perf.

Gregory Hainaut 0958b9db8e gsdx-ogl: use the standard openGL name
Function pointer was mangled to avoid any collision. Nowadays all symbols
are hidden so no risk of collision.

Syntax is nicer beside it would allow to put back GLES3.2. I think it
supports most of the used extension.

glActiveTexture & glBlendColor are provided without symbol query.

Akash b97018932d GSDX: Rework Internal Resolution function
upscale_multiplier function values have been changed to allocate native resolution and also move custom resolution to 9.
Remove the old native checkbox value and include Native in the combo box.
Internal GSDX functions have also been updated with this new update to the upscale_multiplier variable.

Gregory Hainaut 78569ee833 gsdx-ogl: redo properly the setup of texture format
* add lengthly comment to explain the format
* Likely reduce the number of shader permutation
* Avoid slow AEM (on GPU)

Expect regressions because TC needs some fixes

v2: fix palette mode

Gregory Hainaut ca9b5ce11d gsdx-ogl: move depth conversion shader
Add 2 new shaders:
* ps_main12: cast a 16 bit depth to a RGB5A1 color
* ps_main16: cast a a RGB5A1 color to a 16 bit depth

Shader might be used in future commit as it seems Silent Hill uses this
kind of format.

Fix tab/indentation too

gsdx: little changes on AF value behavior.
2015-08-21 11:29:49 +01:00
Akash 3c9ca799a6 Remove anisotropic filtering checkbox value.
Removes the checkbox of Anisotropic filtering from the GSDX plugin settings, the checkbox was usually used to enable & disable the AF which is not necessary since there is an option in the drop down list for disabling AF.
the internal function value of "AnisotropicFiltering" has been replaced with "MaxAnisotropy" for detection.
the detection uses the function getconfig("MaxAnisotropy", value)  where value 0 means disabled and value is the default value when no value is set in the INI file.

Gregory Hainaut b7e16b5989 gsdx-ogl: clean the blending management
Intially GSBlendStateOGL was an alias of the m_blendMapD3D9 array

The object was replaced by an index in the array. Save 2k of memory duplication.
And too much useless code.

v2: push/pop blending state in DATE stuff
v3: remove m_state which is useless now

Gregory Hainaut e026f1bac6 gsdx-ogl: implement a fast accurate colclip algo
The idea is to use a floating texture to accumulate the data and
then do a final postprocessing pass to apply the modulo

v2:
* use bounding box to
* fix vertex corruption issue
* use negative number in shader which allow to use half float (+12
  fps@4x)

Gregory Hainaut ae8df002af gsdx-ogl: optimize Cs * As + Cd and Cs * Af + Cd blending
Basically the code does the alpha multiplication in the shader therefore
the blend unit only does a pure addition. This way the multiplication is
accurate and accurate_blending doesn't requires a costly barrier.

This code also avoid variable duplication to make the code more separated.
Hopefully blending can be done in a separated function

It is preliminary work to support fast color clipping with HDR

v2: fix assertion compilation failure

v3: fix regression in not accurate mode

v3: Cs * As/Af is not an accumulation

Those cases don't need the Cd addition and were already optimized anyway

Fix a regression on GoW2

Gregory Hainaut 5c740ff41e gsdx-ogl: wipeout AlphaStencil & Alpha hack
Accurate options do a better jobs. Technically it can still
be useful for old gpu/driver that doesn't support the GL4.5 extension.

On Windows, you can still rely on Dx

On linux, free driver support it (except Intel)

Gregory Hainaut 36e83b42ce glsl: round texture and fragment color as the SW renderer
GS uses integer value and does integer operation too.

This commit trunc the sampled texture, the interpoled fragment color
and the product of the 2.

It impacts negatively the perf of about 3/4% (GPU) but it fixes rendering on
suikoden and potentially some others games too.
