Gregory Hainaut ced2dd9200 gsdx: hidden option disable_hw_gl_draw
OMG, Zone of Ender got a speed boost from 11 fps to 45 fps

Seriously, the goal is to allow benchmarking GSdx without too much overhead of the main renderer draw call

Note: unlike the null renderer, texture/vertex uploading, 2D draw, texture conversions are still done.

Jason Brown b8a84d170a Added OSD Manager which depends on FreeType2. Added functions into GSDeviceOGL to render OSD and a point shader. 2017-01-03 10:43:56 +01:00
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 7ca9ca9465 gsdx: new parameter for merge virtual function
* Add full PMODE register to replace slbg/mmod
* Add full EXTBUF register (will allow to emulate write feedback)
* Add a third source (which will actually be the destination of the
  write feedback)

Gregory Hainaut 5ced9c1f19 gsdx mipmap:ogl: plug trilinear/mipmap2 option
mipmap option 3. Actually maybe a separate tri-linear option will be better

m_mipmap == 2 => use manual PS2 trilinear/mipmap
Otherwise
m_filter == 3 => always use full automatic trilinear interpolation
m_filter == 4 => use automatic trilinear interpolation when PS2 uses mipmap
m_filter == 5 => like 4 but force bilinear interpolation inside layer

Gregory Hainaut a8a2db8eb1 gsdx mipmap:ogl: extend HW sampler with tri-linear filtering
v2:
* use nice enum
* use bilinear info when there is no mipmap (more accurate)

Gregory Hainaut 677f890c5c gsdx debug: static GSState::s_n
This way you can access the current draw call anywhere. Very useful for debug.

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 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 2e7fab7813 gsdx sw: avoid aliasing issue, clear function was wrong anyway
Value must be un-normalized. Function is only used with 0.0 so
API was updated to only use the 0 case.

Gregory Hainaut b6a55f50ab gsdx ogl: fully initialise PSConstantBuffer structure 2016-07-21 09:51:16 +02:00
Gregory Hainaut 16c2baa0df gsdx-ogl: don't hardcode the accumulation blend trick
Perf impact is bigger than expected
2016-07-07 19:56:23 +02:00
Gregory Hainaut d7c1faf563 gsdx ogl: add GPU timers to measure time between 2 vsync
So far only basic stuff (min/mean/max frame rendering time)
2016-06-26 15:34:36 +02:00
Gregory Hainaut 79587215bb gsdx ogl: add the option force_texture_clear for test purpose
Might be completely useless.

1 => always clear framebuffers and textures to black (aka 0)
2 => always clear framebuffers and textures to red

Gregory Hainaut 3234c8241b gsdx ogl: massively extend glsl self test
* Support Mesa Nouveau IR (free driver for Nvidia's GPU)
  => Print intermediate representation + final shader
  => Dump GPR usage
* Move dumped shader in /tmp/GSdx_Shader/<sub_dir>
  =>  Avoid the landing of 3 thousands of files in $PWD ^^
* Use function instead of macro

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 959abe64f8 gsdx ogl: implement wildhack on the CPU
Speed impact is likely small and the plan is only to keep a single Vertex Shader
2016-06-01 09:29:56 +02:00
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
2016-05-29 10:13:43 +02:00
Jonathan Li da2046e90e gsdx: Use alignas instead of __aligned
__aligned is defined in FreeBSD headers and will cause compile errors.
2016-05-21 13:23:11 +01:00
Gregory Hainaut 3ab12cef2f gsdx ogl: accelerate special case of accurate date.
Game often uses date to allow a single pixel pass. If this
use case is detected, stencil buffer will be cleared after first pixels
that pass both depth&stencil test.

It seems to reduce the load on the GPU.

Note: with the help of texture barriere, maybe we could implement the algo
with a single pass.

Gregory Hainaut 5b061e062c gsdx ogl: replace ClearRenderTarget_i by glClearTexSubImage
Avoid state change, avoid potential texture buffer reallocation

Note: require GL_ARB_clear_texture

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

v2: forget to update the precompiled shader...
2016-05-07 22:46:41 +02:00
Gregory Hainaut 14e1ed06df glsl: add an HLE shader for Urban Chaos
Pro:
* Replace 140 draw calls into a single one
* No complex texture conversion/lookup
* smaller solution than a generic solution

Gregory Hainaut c445a14c46 gsdx ogl: extend shader to lookup a single channel 2016-04-28 22:56:38 +02:00
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 4281b8630b gsdx ogl: remove the useless shadeboost Constant Buffer 2016-04-24 11:08:14 +02:00
Gregory Hainaut 3f404c8edb gsdx-ogl: update shader pipeline intertace to use vs/gs/ps triplet
Better to have 1 function calls with 3 parameters rather 3 functions call with 1 parameter.

Gregory Hainaut f751f70b1e gsdx ogl: GL_ARB_clip_control is now mandatory 2016-04-07 21:57:54 +02:00
Gregory Hainaut b8a023d158 gsdx ogl: mark OGL object as final
Give the compiler more devirtualization hint
2016-04-05 00:01:43 +02:00
Gregory Hainaut decac5fd12 gsdx ogl: implement an empty BeginScene
Compile will devirtualize it and then remove it during the inline.
2016-04-04 23:32:11 +02:00
Gregory Hainaut e3787b6b3c gsdx-ogl: use final qualifier to help compiler
Improve Devirtualization optimization

Gregory Hainaut bc73195193 gsdx-ogl: pack more tightly the FS UBO
Merge TA vec2 + Af vec1 into a single vec4
2016-03-10 18:29:05 +01:00
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

Gregory Hainaut 6561fbc831 gsdx-ogl: only enable aniso when sampling from the HW texture unit
Potentially help issue #884

Jonathan Li cbd2417833 gsdx:ogl:windows: Fix calling convention mismatch
OpenGL does not use the cdecl calling convention (which is the default
calling convention for GSdx on Windows). Since DebugOutputToFile is used
by OpenGL, it needs to use the same calling convention that OpenGL uses.

This fixes a debug build crash when the OpenGL renderers are used and
debug_opengl is nonzero in the ini.

Gregory Hainaut 5fb8c7e65c gsdx: initialize members in constructor of objects
A couple of useless members were removed too.

Also fix wnd initialization

Coverity:
CID 146955 (#1 of 1): Uninitialized pointer read (UNINIT)

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
2015-09-11 14:14:22 +02:00
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

Gregory Hainaut df3ade896b gsdx-ogl: use integer for blend factor
Integer argument&comparison might be lighter

V2: Forget to change one OMSetBlendState call
2015-08-09 13:44:05 +02:00
Gregory Hainaut 5b57405517 gsdx-ogl: blend management cleanup
