I believe all glsl files are cleaned up now.

lightningterror d7cdbf6f27 Gsdx: Point Sampler changes.
Re add point sampler to OpenGL. Fixes graphical issues when
Allow 8-bit textures is enabled on AMD gpus.
Issue: https://forums.pcsx2.net/Thread-GSDX-Hardware-mode-Bug-Report-Allow-8-bit-Texture

Adjust the code to be easier to read, and execute the gl code only on amd - suggested by Gregory.

Remove useless ATI_SUCKS define in tfx shader.It wasn't used anywhere outside of the shader.

Gregory Hainaut c5d35d434c glsl: reduce geometry shader complexity
output 1 strip of 2 triangles instead of 2 strips of 1 triangle.

Potentially it would reduce the geometry shader overhead. And it
might avoid a middle line in sprite in some AMD GPU/driver/OS
bad combination

Gregory Hainaut 61a7c747e1 gsdx-ogl: alternate implementation of half pixel offset
The previous implementation of HPO adds an offset on vertex position. It
doesn't always work beside it moves the rendering window.

The new implementation will add a texture offset so that instead to sample
the middle of the GS texel, we will sample the middle of the real texture texel.

It must be manually enabled with
* UserHacks_HalfPixelOffset_New = 1 (keep a small offset as intended by GS effect)
* UserHacks_HalfPixelOffset_New = 2 (no offset)

v2: always apply a 0.5 offset in case of float coordinates (Tales of Abyss)
Might break other games but few of them uses float coordinates to read
back the target

Gregory Hainaut c2229e3c0b gsdx-ogl: add a texture offset uniform parameter to vertex shader
It would be used for a new implementation of the half pixel offset hack

Hopefully it doesn't badly impact the perf on low end iGPU

Gregory Hainaut e80ca0fa92 gsdx ogl: of course some driver don't work with GL_ARB_enhanced_layouts
Windows and (AMD or Intel)
2016-10-23 12:48:23 +02:00
Gregory Hainaut 8fdf973e66 gsdx glsl: add basic support of GL_ARB_enhanced_layouts (GL4.4)
Hardcode location of interface to the location 0. If I understand the
spec correctly (unlikely), variable in interface will get successive
location.

Goal is to reduce driver work. Instead to compute some location based on
name matching approach (and silly validation), the driver can now use
static allocation.

Tests on future Mesa 13 are welcome

Gregory Hainaut c2b67ccb78 gsdx ogl: implement an alternate shader for Jak Shadows
The game sets the framebuffer as an input texture. So I did the same for
openGL. Code is protected with a CRC. It is working because the game want to sample
pixels.

For the record, I tested it GTA too, it doesn't work as expected because
the game will resize the framebuffer to a smaller one. So you don't have
the guarantee that pixel will be read before a data write.

Note: it requires at least accurate blending set on basic

Note: I need CRC of all Jak games that suffers of this issue. Thanks you :)

Gregory Hainaut 1fb2c66a21 gsdx ogl: Unscale line
Line thickness will be increased to N pixels (N is the upscaling factor).

Code will also be enabled by UserHacks_unscale_point_line = 1

Gregory Hainaut 018895067b gsdx ogl: restore code to unscale point
enabled by UserHacks_unscale_point_line = 1

Point will be transformed into a NxN square sprite. (N is the upscaling factor)

Gregory Hainaut 2b00447a43 glsl: optimize the number of active constant buffer
Increase the performance on the free driver (Nouveau)

Currently the driver validates all UBO when only 1 is updated. It
is clearly a bad idea to put all UBO in a single common headers.

Gregory Hainaut 5d49a6b685 gsdx ogl: replace 4 VS shader variation by an AND mask
Perf will be roughly the same. However there is a single VS for all
the HW emulation.

Gregory Hainaut f7ddd488e1 gsdx ogl: Extend uniform buffer with channel parameter
Instead to use the standard ps ubo which is used every draw call.
I reused a barely used buffer to reduce the extra cost of the upload

Gregory Hainaut a7ba779ba8 gsdx ogl: another HLE channel effect for terminator 3
Same as before but with a different fbmask value (I don't know why but
I have the feeling that I might need the others value too)
2016-05-20 19:55:39 +02:00
Gregory Hainaut 1c21ea955c gsdx ogl: HLE channel effect for terminator 3
Unfortunately I think the game uses another similar effects

Gregory Hainaut d41613c46a gsdx ogl: add a Tales of Abyss HLE shader
Again fast and efficient but it relies on CRC

Gregory Hainaut d5681ba01c glsl: fix a bug in urban chaos hle shader

Gregory Hainaut 70ee8c5bc4 gsdx ogl: add an HLE brightness/contrast shader for GT series.
It works and it is very fast. But it relies on CRC

Others effect need to be tested as well

Gregory Hainaut fda511a949 gsdx glsl: extend hw shader to sample depth texture
Will use integral coordinate to avoid any rescaling.

Bilinear interpolation isn't supported. I don't think it is allowed to
filter a depth texture anyway.

Gregory Hainaut f8c442cf76 gsdx-ogl: make VS more generic
Texture coordinate could be dummy/float/int integral/int normalized.

Old behavior:
* VS was in charge to select the texture coordinate
* int integral format wasn't supported

New behavior:
* Always compute all formats
* FS will be in charge to select the good format

Impact:
* VS will be slightly slower but it reduces shaders permutation from
   little to 0 (won't be bad for CPU)
* FS speed isn't impacted as 2 separate code paths were already required
  to support both format
* Rasterizer will be 33% slower but unlikely to be the limited factor of
  the GPU
* In future we could directly use the integral format in the FS.

V2: remove useless PSin_t

Jonathan Li 1659d5974e gsdx-ogl: Fix scanline, diagonal, triangular TV shaders
PSin.p is normalised, so integer conversions won't work. Use
gl_FragCoord instead.

Gregory Hainaut a8968257db glsl: keep fract in [0;1] range
Shin Megami Tensei Lucifers seems to generate infinites values.
I suspect that DX always clamp fract output.

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 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
