Gregory Hainaut 08291aed0c gsdx-ogl: color state impact the clean command 2015-05-15 15:25:45 +02:00
Gregory Hainaut 613e215c73 gsdx-ogl: add some note for the persistent buffer + add a flush 
Persistent is slower (at least on my gs dump) because data is put
in  host instead of the video memory

I don't understand why upload the data directly to the video memory
is faster
 2015-05-15 15:25:45 +02:00
Gregory Hainaut 5628bfb20c gsdx-ogl: drop old code 
I have group so it doesn't pollute anymore gl trace

Gregory Hainaut bd96a73580 gsdx-debug: trace texture cache hit/miss/removal 
Actually only a small part but I think it is enough to help debugging
tc issue.
Only enable it on debug because it is quite verbose
 2015-05-13 09:01:04 +02:00
Gregory Hainaut 5e9a3a424e Merge pull request #479 from PCSX2/gsdx-texture-cache

Gregory Hainaut b7a9465963 gsdx-ogl: update the device to use the new texture flags 
Hopefully it will increase a bit the speed
 2015-05-12 18:18:20 +02:00
Gregory Hainaut 3e784d57e8 gsdx-ogl: add some flags to trace texture state 
goal1: avoid 2 consecutives clean of the render target
goal2: only invalidate texture correctly
 2015-05-12 18:03:06 +02:00
Gregory Hainaut 2e34d48e97 gsdx-ogl: add a virtual GetID method for texture

Gregory Hainaut 4e222f18cd gsdx-ogl: it was a bad idea to use DSA on fb 
Actually I'm not sure we can mix both dsa/standard approach
 2015-05-11 18:04:16 +02:00
Gregory Hainaut f37f3cb3cf gsdx-ogl: improve texture uploading 
Initially we copy pitch by line in the PBO and tell the dma to only
use the first valid byte.

Now, we only copy useful data to the PBO. It reduce the copy and PBO memory requirement.

It seems a bit faster on native resolution

Gregory Hainaut 4e2e9aa56c gsdx-ogl: always read the first attachment of the fbo 2015-05-11 16:28:34 +02:00
Gregory Hainaut cb6e8a7d6a gsdx-linux: Don't enable EGL by default 
I was hoping that EGL become a standard much more faster. Currently it is an useless dep
so let's disable it by default.

Gregory Hainaut 643b1647c4 gsdx-gui-linux: add some tooltips for the hw options 2015-05-11 14:12:41 +02:00
Gregory Hainaut 921fa3bab8 gsdx-ogl/linux: drop fba option 
It is useless as DX11
 2015-05-11 13:57:26 +02:00
Gregory Hainaut f0de7d6386 gsdx-debug: add 2 extra frames in GS dump 
Initially I was afraid of the size increase but it can be
higly compressed.

Sometimes image was computed inside a RT but never outputed to
the screen which remains black. It is annoying to see the glitches

This reverts commit 2dcffe7fa4.
 2015-05-11 12:15:38 +02:00
Gregory Hainaut 2dcffe7fa4 gsdx linux: drop aligned stack option 
I think the bug was related to a wrong declaration of exported function without stdcall
 2015-05-11 11:35:34 +02:00
Gregory Hainaut 286fe4db8c cmake/gsdx: check png++ is installed to support png image 
Otherwise fallback to bmp file
 2015-05-11 11:32:13 +02:00
Gregory Hainaut 30e3956ea7 gsdx-ogl: avoid issue with apitrace

Gregory Hainaut 5565544ba6 gsdx-ogl: DATE with texture barrier 
Much faster for small batch that write the alpha value. Code can
be enabled with accurate_date option.

Here a summary of all DATE possibilities:
1/ no overlap of primitive
    => texture barrier (pro no setup of stencil and single draw)

2/ alpha written
    => small batch => texture barrier (primitive by primitive). Done in N-primitive draw calls.
    (based on GL_ARB_texture_barrier)

    => bigger batch => compute the first good primitive, slow but only 2 draw calls.
    (based on GL_ARB_shader_image_load_store)

    => Otherwise there is the UserHacks_AlphaStencil but it is a hack!

3/ alpha written
    => full setup of stencil ( 2 draw calls)

Gregory Hainaut 7fac25edb0 glsl: add shader implementation of impossible blend 
Issue: I don't know if destination alpha value must be multiplied by 2.0f
 2015-05-09 15:02:34 +02:00
Gregory Hainaut f029e4763f gsdx-ogl: add the alpha value in a constant buffer 2015-05-09 15:02:34 +02:00
Gregory Hainaut 472608b879 gsdx-ogl: add accurate blending implementation 2015-05-09 15:02:13 +02:00
Gregory Hainaut 1e8aea033c gsdx-ogl: add a wrapper to control the drawing of primitives 
No barrier => draw all primitives
Barrier but without overlap => draw all primitives
Barrier with overlap => draw primitive by primitve

It will ease the implementation of accurate blending and why not date too
 2015-05-09 15:01:39 +02:00
Gregory Hainaut 625d65d4b4 gsdx-ogl: encode the bogus id as shader parameter 2015-05-09 14:55:44 +02:00

Gregory Hainaut 1addae1993 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.
 2015-05-08 19:28:16 +02:00
Gregory Hainaut b490085214 gsdx-ogl: add 2 options in the GUI to ease testing 
accurate_date => use an emulated stencil to compute destination alpha
    test (could be slow)

accurate_blend => do nothing (future)

Gregory Hainaut 4c91bab00e gsdx: fix compilation error on release build 2015-05-08 19:28:00 +02:00
Gregory Hainaut 6d31124d3a gsdx-debug: only enabled advance gl debugging on linux 
It will avoid some crash on windows for driver that doesn't support
the extension.

Make debug support mandatory for debug build on linux.
 2015-05-08 09:54:34 +02:00
Gregory Hainaut e87d129b09 gsdx-ogl: more verbose debug 2015-05-08 01:01:01 +02:00

Gregory Hainaut b39b9c9f55 gsdx-gui-linux: use callback everywhere 
Note: texture offset doesn't work nicely (you need to press enter
to validate the change)
 2015-05-07 22:13:49 +02:00
Gregory Hainaut d428e0d19d gsdx-gui-linux: move table filling into separate function 
It is much easier to read this way. I need to use callback for the remaining
object before I can move everything out of main function.
 2015-05-07 22:13:49 +02:00
Gregory Hainaut 917a6c28e5 gsdx-gui-linux: factorize code

Gregory Hainaut cc4713d379 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 :)
 2015-05-06 19:09:13 +02:00
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 6d65867b26 gsdx-ogl: comment point_sampler

Gregory Hainaut 6fca3b421d gsdx-debug: dump register context in a .txt file 
+ Realign s_n number if frame is skipped

This way it is easier to understand current draw. It also eases
comparaison between SW/HW.

 2015-05-01 14:18:05 +02:00
Gregory Hainaut a0c17ae0a4 gsdx: use vertex storage by default 
It is faster on games that draw lots of primitives and in low upscaling.

Gregory Hainaut 757726bb91 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 ;)

Gregory Hainaut 75817bb27b gsdx-ogl: add a quick and dirty DSA layer emulation 
The global idea is to use
1/ bind in tight loop
2/ DSA otherwise (to avoid any binding in tight loop)

Gregory Hainaut 7b0775d887 gsdx-ogl: add some fences to protect the upload of vbo buffer 
This way ogl_vertex_storage must be safer to activate

And it brings a nice performance boost (game with lots of primitives and
reasonable upscaling)

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 18:32:08 +02:00
Gregory Hainaut 03e72781aa 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.

Gregory Hainaut f6652e9a50 gsdx-ogl: disable slow and buggy code until I found a better solution 
ogl_texture_storage 1 creates texture corruption.

Advance date is too slow, code need to be updated (properly) to uses 2 passes only not 3
Maybe one could be enough (sometimes)
 2015-04-22 09:33:41 +02:00
Gregory Hainaut b32f808fd4 gsdx-ogl: increase the number of pbo 
It would cost 16MB of extra storage on the GPU but it might
reduce conflict of texture upload.
 2015-04-22 00:40:38 +02:00
Gregory Hainaut bd6ea17bdc gsdx-ogl: speed improvement for DATE 
DATE is implemented in 2 ways.
1/ with stencil
2/ purely in FS (sw)

I kept method 1 to reduce the work on method 2. It sucks for performance.
So it would be either 1 or 2.

Note: DATE has a big impact on higher upscaling
Note2: you can disable the 2nd method with this configuration parameter

override_GL_ARB_shader_image_load_store = 0
 2015-04-22 00:36:34 +02:00

For testing purpose. I don't know which one is better.

It seems flushing have less fps fluctuation than barrier.

Performance note (warm cache+gs replay on colin3)
60 fps -> 76 fps

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).
