Gregory Hainaut 530e4ce776 gsdx-ogl: drop hack that rescale primitive (to avoid upscale glitch) 
Rendering is bad. It renders sprites at native resolution.
 2015-05-06 19:09:13 +02:00
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
 2015-05-02 16:56:18 +02:00
Gregory Hainaut 73d04e33e9 gsdx ogl: clean various comment and old code 2015-05-01 20:04:23 +02:00
Gregory Hainaut 335695bd0e purge GLES from GSdx ! 
mobile will use vulkan (or any new API) anyway
 2015-05-01 20:02:17 +02:00
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
 2015-04-27 18:52:55 +02:00
Gregory Hainaut 46ff4dc3d3 gsdx-ogl: hardware unit only support normalization of 4 bytes... 
(At least on recent AMD GPU)
 2015-04-27 18:51:59 +02:00
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
 2015-04-25 20:23:26 +02:00
Gregory Hainaut 15ae9996bb glsl: format white space + comment 2015-04-25 12:50:12 +02:00
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
 2015-04-24 21:12:33 +02:00
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.
 2015-04-24 20:13:38 +02:00
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
 2015-04-20 07:18:09 +02:00
Gregory Hainaut 6d253c0b8f glsl: fix debugging of tex coordinate in apitrace 2015-04-20 07:18:08 +02:00
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).
 2015-04-20 07:18:08 +02:00
Gregory Hainaut 16e6d0d305 glsl: move shader into a separate directory 
Only keep glsl_source.h for clarity
 2015-04-19 18:49:02 +02:00
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.
 2015-04-19 18:49:02 +02:00
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
 2015-04-13 22:14:36 +02:00
Gregory Hainaut 05eb1641f2 gsdx: add glsl debug capabilities 
Useful to debug bad texture sampling
 2015-04-08 10:15:25 +02:00
Gregory Hainaut e40a26be19 gsdx: add some helper to debug openGL renderer 2015-04-03 20:28:44 +02:00
Gregory Hainaut 29a14f5667 sed -i -e 's/seperately/separately/' 
Thanks micove again

gabest11 9e20387595 Modified for opencl 1.1. While it runs on nvidia cards now, you can't use its sdk to compile gsdx, cl.hpp is missing there. Intel or amd is ok. 2014-12-02 00:16:34 +01:00
gabest11 263c097d13 solution for 32-bit z values in opencl and other minor optimizations 2014-12-02 00:16:34 +01:00
gabest11 c64f9ad9b1 squishing opencl bugs, there aren't many left hopefully 2014-12-02 00:16:34 +01:00
gabest11 ba1e522bbb Less opencl bugs, some games are actually playable now, there are still texture errors. 2014-12-02 00:16:34 +01:00
gabest11 881735b562 minor merging errors 2014-12-02 00:16:33 +01:00
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
 2014-11-20 22:07:44 +01:00
Gregory Hainaut 8c90e7cafc gsdx-ogl: support latest fxaa version 
Only tested on Nvidia, please report any issue with your driver

Note: requires GL4 GPU
 2014-11-10 10:39:55 +01:00
Gregory Hainaut 84f844767c gsdx-ogl: micro optimize PSConstantBuffer cache 
Might help to save a cache line on the CPU :)
 2014-11-08 21:39:17 +01:00
Asmodean df0a9c4683 Some small fixes, that I noticed. 2014-11-06 10:56:33 +00:00
Asmodean 937e475169 [Post-Processing] Update GSdx FX effect suite to latest version. 2014-11-03 07:15:34 +00:00
Gregory Hainaut ccc1137e12 gsdx-ogl: merge the two vertex buffer format 
* Only a single VAO
    => Format is set once
    => Only a single bind at startup
    => GSVertexBufferStateOGL is nearly useless
    => barely faster but better than nothing :)
 2014-10-02 20:44:22 +02:00
Gregory Hainaut d37cc8e1e7 gsdx-ogl: GL_ARB_shading_language_420pack is now mandatory 
All API/drivers support it so time to remove the fallback.
 2014-10-02 20:44:22 +02:00
Gregory Hainaut 594f6c33a2 gsdx-ogl-ES: require GL_EXT_shader_io_blocks + GLES3.1 
Allow to use same shader interface for all API

Note: on the GL API it will require GL3.3 (see next commit)
 2014-09-30 22:18:01 +02:00
Gregory Hainaut 4659184cc1 gsdx-ogl: add support of clip_control (depth only) 
* replace the [-1;1] depth range of openGL with the DX range [0;1].
 2014-09-28 12:00:34 +02:00
Gregory Hainaut 0d45e6d70e gsdx-ogl: avoid to send constant to the GPU 
It was a waste of bandwith
 2014-04-06 10:44:40 +02:00
Asmodean.pcsx2 0651e45460 GSdx: Just some cleaning. 
Reformatted fx files that were causing issues on certain text editors. They should now display correctly in those editors.
