Gregory Hainaut 9b69afe541 gsdx-ogl: typo that broke TC offset hack 2015-09-20 22:19:45 +02:00
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 ddc03cbccf gsdx: add a nice enum to replace the hardcoded convert shader 2015-09-08 16:51:24 +02:00
Gregory Hainaut a46c11b088 gsdx-ogl: delete various leftovers 2015-08-22 13:33:32 +02:00
Gregory Hainaut 7002ff3ec3 gsdx-ogl: move texture scale from vs_cb to fs_cb 
It avoid useless update of the vs_cb.

Gregory Hainaut 499206f0ea gsdx-ogl: disable advance rendering when drivers don't support it 2015-08-22 12:22:35 +02:00
Gregory Hainaut 37f9bcf9cb gsdx-ogl: reduce state change 
* don't dirty aref when a fog color is uploaded
* only set clamp mode in clamp mode (region clamp is handled in shader)

v2: fix SSE2/3 compilation
 2015-08-20 23:01:43 +02:00
Gregory Hainaut c5a786ed2c gsdx-ogl: remove support WMS/T == 2 in hardware unit 
I think behavior was wrong because only first texel coordinate was clamped.

Beside we can't interpolate if AEM isn't yet applied
 2015-08-20 23:01:43 +02:00
Gregory Hainaut 6b84a89b6a gsdx-ogl: remove old ati hack for point sampler 
Was never used on openGL

In the future absolute coordinate will be use anyway

Gregory Hainaut 37661f3a86 gsdx-ogl: fix blending regression (VP2) 
Negative factor must be disabled in negative accumulation "-Cs*As + Cd"
Shader must output Cs*As and blending unit will do the Cd - C subtraction
 2015-08-18 09:14:11 +02:00
Gregory Hainaut 260c12756a gsdx-ogl: accelerate Cd - Cs * Alpha in sw blending 
It is similar as Cd + Cs * Alpha except the operator

It would help to emulate other color clipping case correctly in basic
mode at full speed

Jonathan Li 6580f4922f gsdx-ogl: correct fbmask conversion on texture shuffle 
Fbmask is RGBA8 and must be converted to RGB5A1
=> bit 31 must be moved to bit 15

Gregory Hainaut c32f1dfc23 gsdx-ogl: fix blend clear regression 
Field selector are very dangerous to use.

Fix #764

Gregory Hainaut 0e3491bd58 gsdx-ogl: always do RW RT check 
Jak uses it with triangle rendering.
 2015-08-15 20:06:34 +02:00
Gregory Hainaut c7b2f9d1d2 gsdx-ogl: setup fbo to always write to first buffer 
GL_NONE was kind of useless because nothing was attached anyway

Gregory Hainaut 9f92f63194 gsdx-ogl: Use GetAlphaMinMax to limit the scope of FULL accurate blending 
Provide a massive speed up in this level.

Gregory Hainaut 61694013a5 gsdx-ogl: compact blending parameter structure 
Save 656B of data. It is good for the cache.
 2015-08-09 13:44:30 +02:00
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 
* reorder the blend function
* remove OM bsel object
* add a bit to support pabe (miss the glsl part)
 2015-08-08 09:18:09 +02:00
Gregory Hainaut 4d12410707 gsdx-ogl: latch constant buffer in rendering object 
* Initialization of the object is done once
* Avoid to reupload it when an useless parameter toggle
 => -10% of UBO update
 2015-08-08 09:18:09 +02:00
Gregory Hainaut b17803bb34 gsdx-ogl: wipeout of GL_ARB_bindless_texture 
Code is completely broken. It doesn't help to improve speed.

Remove 200 lines ;)
 2015-08-08 09:16:49 +02:00
Gregory Hainaut b7e16b5989 gsdx-ogl: clean the blending management 
Intially GSBlendStateOGL was an alias of the m_blendMapD3D9 array

The object was replaced by an index in the array. Save 2k of memory duplication.
And too much useless code.

v2: push/pop blending state in DATE stuff
v3: remove m_state which is useless now

Gregory Hainaut 717f0fcb4d gsdx-ogl: optimize fbmask setup 2015-08-05 22:55:12 +02:00
Gregory Hainaut 73e2ff6ff6 gsdx-ogl: change PrimitiveOverlap algo from O(n^2) to O(n) 
+ only enable this optimization when it is useful (date or sw blending)

Less impact on the perf even for big vertex array

Gregory Hainaut 45bb27d6db gsdx-ogl: extend HDR colclip to 32 bits texture 
Unfortunately 16 bits wasn't enough for Castlevania.

Gregory Hainaut d80aa0b0bd gsdx-ogl: remove 2 printfs 
GL_INS is a better tracing solution
 2015-08-04 20:47:02 +02:00
Gregory Hainaut 744f9ebc09 gsdx-ogl: rare corner case when both texture shuffle and date are enabled 
In texture shuffle mode the texture data is either RG or BA. It means
that DATE must either checks MSB of G or A.

Close #693

Gregory Hainaut a0edcb58af gsdx-ogl: extend cclip blending level with destination alpha blending 
The purpose is to emulate correctly destination alpha factor

An alpha channel of 128 is 1.0 in the GS but only ~0.5 in the GPU

I think few draw call use destination alpha so impact on perf must remains small.

Gregory Hainaut 8554f32086 gsdx-ogl: clean the blend table 
Remove old shader define
Prefix macro with BLEND_
Add some notes to explain the special symbol

Gregory Hainaut 93c47feb7c gsdx-ogl: replace old colclip algo with the HDR algo 
Similar speed but more accurate

Allow to clean the code
 2015-07-31 09:45:28 +02:00
Gregory Hainaut 83f874db93 gsdx-ogl: remove bsel.ps 
Just clear bsel.abe to disable blending
 2015-07-31 09:45:28 +02:00
Gregory Hainaut 25298c70f7 gsdx-ogl: move blending management into a separate function 2015-07-31 09:45:28 +02:00
Gregory Hainaut 25bd5f5e85 gsdx-ogl: request texture barrier to emulate accurate date 
Actually it can partially be done with GL_ARB_shader_image_load_store
extension. However all drivers that support shader_image have
texture barrier too.
 2015-07-31 09:45:28 +02:00
Gregory Hainaut 2901e94ebc gsdx-ogl: always bind the RT as input texture 
To avoid code duplication
 2015-07-31 09:45:28 +02:00
Gregory Hainaut 1fe3e04ce3 gsdx-ogl: don't alias m_env/m_context variable 
It is cumbersome to move code
 2015-07-31 09:45:28 +02:00
Gregory Hainaut 8f27a5a92b gsdx-ogl: only enable fast accurate colclip in level3 
Until we drop the old method
 2015-07-31 09:45:05 +02:00
Gregory Hainaut e026f1bac6 gsdx-ogl: implement a fast accurate colclip algo 
The idea is to use a floating texture to accumulate the data and
then do a final postprocessing pass to apply the modulo

v2:
* use bounding box to
* fix vertex corruption issue
* use negative number in shader which allow to use half float (+12
  fps@4x)
