Gregory Hainaut 5565544ba6 gsdx-ogl: DATE with texture barrier
Much faster for small batch that write the alpha value. Code can
be enabled with accurate_date option.

Here a summary of all DATE possibilities:
1/ no overlap of primitive
    => texture barrier (pro no setup of stencil and single draw)

2/ alpha written
    => small batch => texture barrier (primitive by primitive). Done in N-primitive draw calls.
    (based on GL_ARB_texture_barrier)

    => bigger batch => compute the first good primitive, slow but only 2 draw calls.
    (based on GL_ARB_shader_image_load_store)

    => Otherwise there is the UserHacks_AlphaStencil but it is a hack!

3/ alpha written
    => full setup of stencil ( 2 draw calls)

Gregory Hainaut 7fac25edb0 glsl: add shader implementation of impossible blend
Issue: I don't know if destination alpha value must be multiplied by 2.0f

I often mix them with the real value...

Gregory Hainaut 1addae1993 gsdx-ogl: don't use extra shader for sprite hack
Atst == 2 && sprite_hack is equivalent to Atst == 1

It frees a bit in the shader selector, and reduces shader combinations.

Gregory Hainaut 530e4ce776 gsdx-ogl: drop hack that rescale primitive (to avoid upscale glitch)
Rendering is bad. It renders sprites at native resolution.

Gregory Hainaut ae70344fbc gsdx-ogl: fix 2 passes DATE with GL42 (override_GL_ARB_shader_image_load_store = 1)
It fixes shadows issue with Persona 3

Gregory Hainaut 335695bd0e purge GLES from GSdx !
mobile will use vulkan (or any new API) anyway

Gregory Hainaut 71e517108d gsdx-ogl: fix colclip
Sotc shadow and likely various games :)

Thanks to pseudo

Gregory Hainaut b65a62096f gsdx-ogl: drop support of ENABLE_OGL_DEBUG
Stencil can be read by GL debugger due to correct mask configuration
2015-04-30 20:02:51 +02:00
Gregory Hainaut eaa0dae305 glsl: drop invariant qualifier
Fix issue #510 and potentially it allows the compiler to  better optimize the code

Gregory Hainaut 46ff4dc3d3 gsdx-ogl: hardware unit only support normalization of 4 bytes...
(At least on recent AMD GPU)

Gregory Hainaut 301fe869c7 glsl: improve the logz handling
This way only 0 and 1 will conflict
2015-04-26 17:51:33 +02:00
Gregory Hainaut 6a3250cad2 gsdx-ogl: fix logz management (FFXII)
The issue is that z+1 overflow if z is UINT max
log2(z) overflow if z is 0

So let's use an or 1 to avoid both overflow

Gregory Hainaut 36514bd95f glsl: fog is a single byte
Give a chance to the driver to optimize if possible
2015-04-24 21:37:37 +02:00
Gregory Hainaut c207632e49 gsdx-ogl: improve date performance for GL45
If there is no overlap, it is allowed to directly read from the render target.

On SotC testcase with 6x scaling: 30fps -> 40fps

Note: it requires GL_ARB_texture_barrier extension so be sure to have a recent driver

Note2: it requires a lots of testing too

Open question: in case of complex date (written alpha)
Will it be faster to split the draw call into multiple call with no
primitive overlap

Gregory Hainaut 795ae50ecd gsdx-ogl: fix the recently broken advance date feature
Now it is really working with a 2 stages shaders but it is still slow.

Gregory Hainaut 89d5e5637c glsl: use an explicit cast insead of notEqual function
If the compiler didn't optimize the code, it will be a bit faster
2015-04-24 18:01:25 +02:00
Gregory Hainaut 56836561f4 glsl: replace runtime condition by preprocessor condition
It might be an easier work for the compiler

I didn't replace all occurences to keep readability
2015-04-24 17:51:29 +02:00
Gregory Hainaut 62489f42f1 gsdx-ogl: add an optimization note for later
Only 1 byte of fog is useful

Gregory Hainaut 31f8c065db gsdx-ogl: implement a new hack UserHacks_UnscaleSprite for opengl
UserHacks_UnscaleSprite = 1 will unscale flat sprites
UserHacks_UnscaleSprite = 2 will unscale all  sprites (don't work well so far)

The idea of the hack is to redo the interpolation of texture coordinate
based on the non-upscaled pixel position.

It avoids various glitches but sprites aren't upscaled anymore (so no
more anti-aliasing, potentially a coefficient can be added).

Gregory Hainaut 16e6d0d305 glsl: move shader into a separate directory
Only keep glsl_source.h for clarity

Gregory Hainaut 55fdf26898 glsl: remove the older file tfx.glsl 2015-04-19 18:49:02 +02:00
Gregory Hainaut 15264c6c63 glsl: split the main shader
* separate VS/GS and FS
* separate subroutine part of the FS

It already complex enough without subroutine stuff. Besides I'm not sure
we will keep subroutine on the future.

Gregory Hainaut 418f2e69a8 gsdx-ogl: implement the wildhack on the GPU
Likely much faster for opengl and much easier to implement

Note: hopefully UserHacks_round_sprite_offset will replace it

gabest11 db7c26cde7 - Experimental OpenCL renderer (missing features: point, line, texture cache, mipmap, aa1, device selection). Needs any OpenCL SDK for the common headers and stub lib to compile, tested with AMD and Intel. Too bad it is not part of the Windows SDK yet.
- Renumbered renderer ids, compatible with old numbering, but it does not follow the mod3 logic anymore.

Gregory Hainaut d21e6ff45f gsdx-ogl: don't declare a sampler variable
Nvidia was complaining on the fxaa shader. In doubt I also replaced it in Asmodean's shader
