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.

gsdx-debug: extend ogl debug capabilities
...
Group opengl calls into a nice name.
Apitrace shows them in a tree format that support folding. Previously it
was a long flat list (10K-40K of lines by frame)
I align the call number with the internal s_n variable. This way it is
easy to map GSdx dump output with the GL debugger :)

gsdx-ogl: use 64 bits counter + fix division factor

I also added a counter of the real size of the texture.
I have a bad overhead for pbo transfer

gsdx-ogl: allow to invalidate the texture

It just a hint to the driver to avoid any useless transfer
I don't expect any change but it is free so why not ;)

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

gsdx-ogl: fix the recently broken advance date feature

Now it is really working with a 2 stages shaders but it is still slow.

gsdx-ogl: avoid to clean fully texture in DATE

Is is useless and it has a small impact on performance for big upscale

gsdx-ogl: drop support of GL_ARB_clear_texture extension
...
Extension is a bit slower.
We use it to clear the RT but we generally use it right away so
we don't avoid the FB attachment.

gsdx ogl: flush vbo range instead of barrier
...
For testing purpose. I don't know which one is better.
It seems flushing have less fps fluctuation than barrier.

gsdx-ogl: improve speed of vertex streaming
...
Note yet enabled because I'm afraid of data corruption but feel free to test it
The option:
ogl_vertex_storage = 1
Performance note (warm cache+gs replay on colin3)
60 fps -> 76 fps

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).

gsdx-ogl: only compile useful VS
...
logz is a constant
wildhack is only compatbile with TME/FST
Compilation goes down from 64 to 20 vertex shaders.

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

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

gsdx-ogl: add a gui option (linux) to select external shader
...
Note: of course it requires a glsl shader ;)
On windows, you can set the path on the ini file. Here an example with linux path:
shaderfx_conf = /home/gregory/playstation/emulateur/pcsx2_merge/bin/GSdx_FX_Settings.ini
shaderfx_glsl = /home/gregory/playstation/emulateur/pcsx2_merge/bin/shader.fx

gsdx-ogl: reduce complexity of clear texture
...
Null is equivalent to a clear to 0.
Note: Code is not yet used because both stencil and depth are cleared.
Future note: stencil can potentially be replaced by load_store_image

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 :)

gsdx-ogl: bump base requirement to 3.3
...
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
