A couple of fallbacks were introduced for the Mesa driver that only support 3.0
DSA will require a recent Mesa which already support GL3.3
Require at least SandyBridge for Intel GPU
* use DebugOutputToFile as a callback of gl error. Add a breakpoint to
find the culprit GL call
* use string instead of char[n]
Note: CheckDebugLog is potentially useless now
* GL_ARB_clip_control: reduce z fighting
* GL_ARB_clear_texture: no real speed gain (but improve code quality)
* GL_ARB_bindless_texture: +1fps (if you're CPU limited)
* require a 3.1 context
* unattach texture of the fbo when they're not used
(avoid to have a texture and depth_stencil with different size)
Note: except minor shader bug it works on Nvidia 340.23.01
This doesn't update the file to the latest version from mingw32 since this is already a custom header stripped from mingw32.
This also fixes the functions for x86_64(verified that it still works for both architectures) and also updates the version inside of GSdx.
Also removes a comment in the GSdx header saying that these functions are broken since they no longer are.
deassert gsopen_done before delete the gs object. Compiler and CPU will
reordonate the store (or not because it is a global variable). Probably not
perfect but better.
Got a crash on GSKeyEvent which I guess wasn't thread safe. So let's ensure
gs is open.
There is no such thing as MGS3 Substance only Subsistence. Substance is MGS2 :P
Also this new CRC is US Disc 2 of Subsistence. The blue stripes should be fixed now I guess.
1/ initReadFifo will be first called on the GS thread
(openGL can only be done on the GS thread)
2/ readFifo will be called on the EE thread. It is not safe too access eeMem from GS
because of memory is virtual
Fix "recent" regression (crash) on Kingdom heart and others game too.
v2: add a len check on GSState::InitReadFIFO
* Fix to create a 3.0 GLES context
* set a default precision to fix most of shader compilation issue
* Crash later because of GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT

Note: it probably doesn't run anymore. My Nvidia driver doesn't support
yet egl/gles so I can't test it. Feel free to contribute.
A bit slower. Maybe because SubData does the copy in the driver thread. My memcpy is done on
the main thread. I'm not sure it would worth an extra thread to copy vertex data to the GPU
Note: testers are welcome. You need to edit the ini file.
"ogl_vertex_storage=1" <= enable the extension
"ogl_vertex_storage=0" <= disable the extension
Again you need the support of GL_arb_buffer_storage (i.e. not catalyst)
Improve arb_buffer_storage implementation
Try harder to align the texture buffer
Strangely arb_buffer_storage is 3 times slower on my PC (nvidia)
Tester are welcome! Open the ini file
"ogl_texture_storage = 1" <= enable the extension
"ogl_texture_storage = 0" <= disable the extension
Note: you need an opengl 4.4 driver or one that support arb_buffer_storage (i.e. not catalyst)
This hack was used because GSReadFifo was called from the EE thread.
Previous commit move the call to the GSThread.
Hopefully avoid flushing the full GPU contex would improve openGL
performance (at least avoid some hiccups ;) )
Note: newer GSdx ogl won't be compatible with older PCSX2

Note: DATE is used for shadows (persona 3) and others effect
You can disable it when you disable gl image extension (override_GL_ARB_shader_image_load_store = 0)
You can also enable it on AMD too (set it to 1 this time) but no guarantee.
If you feel the extension is too slow, you can try disable some gl barrier (aka "damn the torpedo full steam ahead!").
It can be done with the option UserHacks_DateGL4 = 1. Otherwise just disable the extension.
Note: don't enable UserHacks_AlphaStencil in the same time. GL_ARB_shader_image_load_store is an alternative implementation.
Enabling both in the same time will lead to undefined (well surely wrong) behavior.

Fixes a small oversight on my part. Which was setting the maximum anisotropy to (0,1,2,3,4) respectively, instead of (1,2,4,8,16). So when you selected x16 for example, you were actually only getting x4 >.>
Corrected now, and you will be getting the full x16 when selected :)

Best setting if you driver support GL_NV_depth_buffer_float => GL_NV_Depth = 1 & logz = 0
Otherwise => GL_NV_Depth = 0 & logz = 1
Explanation of the bug:
Dx z position ranges from 0.0f to 1.0f (FS ranges 0.0f to 1.0f)
GL z Position ranges from -1.0f to 1.0f (FS ranges 0.0f to 1.0f)
Why it sucks:
GS small depth value will be "mapped" to -1.0f. In others all small values will be 1.0f! Terrible lost
of accuraccy.
The GL_NV_depth_buffer_float extension allow to set the near plane as -1.0f.
So
"GL z Position ranges from -1.0f to 1.0f (FS ranges 0.0f to 1.0f)"
will become
"GL z Position ranges from -1.0f to 1.0f (FS ranges -1.0f to 1.0f)"
and therefore
"z posision [0.0f;1.0f] will map to FS [0.0f;1.0f]" as DX
Yes we just get back all precision lost previously :)
However you need hardware (intel?) and driver support (free driver?/gles?) :(

Add another scanline algorithm, made by pseudonym. This one is pretty fancy, using a cosinus function for generating the dark lines.
It only works on unscaled output, so use software rendering or native resolution for hardware.
It's an effect that works best on 240p converted games (like the SNES titles in Mega Man Collection).

- FXAA shader replaced by Asmodeans shader suite 'PCSX2 Fx 2.00 Revised'.
This is an entire enhancement suite with many configurable options like FXAA, texture sharpening
or lighting tweaks. Some of the effects are pretty advanced so kudos to him allowing it to be integrated with GSdx! :)
Note that there's no interface for the tweaks yet. Until those are done, the defaults will be used.

Performance note, it might be faster to replace the MODULO with an AND. Not sure on the impact
for the new time stretcher algo.
GSdx: fixed use-after-free (linux)
PCSX2:

* sio_buffer out of bond (-1). Maybe we can move the flush in the 2 if previous branch. It would
avoid the extra test.

* GL_ARB_shader_subroutine for perf
fix for nvidia => add missing shader declaration. Nvidia got +4fps on colin3 :)
For the moment only 2 PS parameters are supported. Code need to be extended to support others games that often
switch shader program (like xenosaga).
require GL4 class hardware and the option override_GL_ARB_shader_subroutine = 1
Note: strangely on AMD linux it is slower!
* GL_ARB_shader_image_load_store for accuraccy (Date)
Use a signed integer texture and reenable color buffer writing
Current status: Amagami_transparency.gs & P3_battle_shadows.gs are now working on Nvidia with a small perf impact.
Current implementation detail:
1/ setup the standard stencil as before
2/ on remaining pixel, draw once to compute first primitive that will write a fail alpha value.
3/ final draw based on primitive id of step 2
Note: I think we would get a bad behavior if depth test&mask are enabled on step 2/3
Note2: on my limited testcase the perf impact was on CPU. It would be possible to merge step1&2 to nullifying it (could
even be faster actually), however it would require more GPU power.
Again require GL4 class hardware. And the option UserHacks_DateGL4 = 1

Card that support gs:
remain only a gs to generate sprite from a line. Even dummy gs are costly for the GPU.
Card that don't support gs:
remove useless copy of color for line and triangle primitives
Note for dx: opengl 3.2 (maybe not gles) supports both flat interpolation
convention (GL_FIRST_VERTEX_CONVENTION or GL_LAST_VERTEX_CONVENTION). It might
be possible to shuffle vertex index to put the last vertex in first position.

The idea was to replace shader program swith by pointer function calls inside
shaders. At least parameters that are often changed between draw call. So far
I only ported atst and colclip. Unfortunately code is "slower" (on GSdx standalone).
For the moment keep the code but disabled.
If I understand well the validation of program is done in the "driver thread"
but the additional call are done in the overloaded MTGS thread. Apitrace
profiling shows faster GPU draw calls. Another possibility is that the driver still
need to validate the draw call because of others state change.
Here some stats on colin3 (90 frames):
without subroutine: UseProgram 125246
with subroutine: UseProgram 2906, subroutine 125945 => 3605 extra calls overhead (not
all parameters are ported to subroutine)
