Gregory Hainaut 1522cba5b0 gsdx ogl: performance note of texture clear vs framebuffer clear 
In case of render target. FB clear is better
 2016-05-16 10:38:47 +02:00
Gregory Hainaut e776118de9 gsdx-ogl: implement previous DATE optimization in a single shader pass 
Faster :) Reduce further the cost of accurate date

The optimization will clear the stencil to 1. So all pixels will have a
single sample that pass both the depth & stencil test. No primitive
overlaps So the destination alpha test can be done directly in the
shader.

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 025be70c42 gsdx-ogl: allow to fallback to a slow accurate DATE when GL_ARB_shader_image_load_store isn't supported 
The best is still to have a DX11 generation GPU
 2016-05-15 16:29:29 +02:00
Gregory Hainaut 5b061e062c gsdx ogl: replace ClearRenderTarget_i by glClearTexSubImage 
Avoid state change, avoid potential texture buffer reallocation

Note: require GL_ARB_clear_texture
 2016-05-15 15:55:31 +02:00
Gregory Hainaut 82060320ef gsdx ogl: use draw list size for sprite instead of vertex number to select date algo 
Latest overlap detection allow to draw multiple sprite instead of 1,
so the limit based on vertex number is too conservative.

Gregory Hainaut c054b097e9 gsdx ogl: fix wrong depth clear 
If a color buffer is still attached and is smaller than depth buffer,
the latter won't be fully cleared.

As a faster alternative, use GL4.4 clear texture function. Avoid to fiddle with
framebuffer and pixel tests.

Fix #1362x Ar Tolenico 2 map clip

Gregory Hainaut cd9ee3c468 gsdx ogl: emulate GL_ARB_draw_buffers_blend and GL_ARB_viewport_array 
New functions only set the parameter to a single buffer whereas old function
set all buffers

Gregory Hainaut 156b6425d2 gsdx ogl: add UserHacks_merge_pp_sprite option to reduce upscaling glitches 
For test purpose, it is higly experimental.

So far it is yield interesting result for tekken5
 2016-05-10 08:12:07 +02:00
Gregory Hainaut c019f86529 gsdx ogl: add a performance note for a potential channel optimization 2016-05-10 08:11:28 +02:00
Gregory Hainaut 4effc70792 gsdx hw: Fix regression on align sprite 
The hack also updates position of not texture mapped sprite.

Unlike the 2nd hack (round sprite) which can be skipped if TME is disabled

Gregory Hainaut 5b04672ba2 gsdx ogl: separate Tales of Abyss/Urban Chaos effect based on the fbmask 
Avoid to rely on CRC
 2016-05-08 17:31:13 +02:00
Gregory Hainaut 48d962e15a gsdx log: print detected crc 
Helpful to get crc from gs dump
 2016-05-08 16:30:50 +02:00
Gregory Hainaut fb6a6f73c4 gsdx: move Tekken5/Tales of Abyss CRC to Dx level 2016-05-07 22:46:42 +02:00
Gregory Hainaut ecbcc566fe gsdx ogl: use GT shader for Tourist Trophy 2016-05-07 22:46:41 +02:00
Gregory Hainaut fc86620327 gsdx ogl: disable channel effect when signature is a bit different 
Hack to avoid regression on Blood Will Tell
 2016-05-07 22:46:41 +02:00
Gregory Hainaut 30b452543a gsdx ogl: tekken5 uses similar effect as Gran Turismo 
So just reuse GT hle shader :) Acid stage is now correct. However it might need
some tuning for others stages.
Still look awful with uspcaled resolution (note internal game framebuffer is around 160x128)
 2016-05-07 22:46:41 +02:00
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 d5681ba01c glsl: fix a bug in urban chaos hle shader 
Bug only impact the lsb bits of the depth conversion, so impact is likely small
 2016-05-07 22:46:41 +02:00
Gregory Hainaut 70ee8c5bc4 gsdx ogl: add an HLE brightness/contrast shader for GT series. 
It works and it is very fast. But it relies on CRC

Others effect need to be tested as well

Gregory Hainaut f34e77f08c gsdx: fix regression on 24 bit format (gust game) 
bpp is the size of the container format but not the size of the format itself.
For PSM24, bpp is 32, trbpp is 24
 2016-05-06 13:49:24 +02:00
Gregory Hainaut e890ce989c gsdx: throw oom exception + error 
Texture can't be NULL anymore, so we can remove a couples of check
 2016-05-05 18:53:51 +02:00
Gregory Hainaut d58b71688b gsdx debug: auto GL_POP 
Nicer and exception safe

V2: miss definition of vs/ps
 2016-05-05 18:53:32 +02:00
Gregory Hainaut 37c7fa7663 gsdx: add draw exception (OOM and Recoverable) 
The exception will free the unused (but allocated) texture aka the emergency break ;)

Recoverable could be useful for unsupported draw call

Gregory Hainaut 055b9c57e7 gsdx tc: use unscaled size as clamping in Target::Update 
Might avoid/reduce crash like #1340

Gregory Hainaut 5948c2d8cd gsdx AMD: broken for broken 
Until AMD release the driver with a fix, I can't use 2nd blending source with SSO.

So let's use the first source. Blending/Alpha will be wrong. But it is likely better
than an uninitialized alpha value.

Akash 21e6a344a2 GSDX: Improvements to the GSDX dialog (#1284) 
GSDX: Improvements to the config interface.

- GSDX: Add new logos to dialog
- GSDX: Remove all the extra null renderers
- GSDX: Changes to renderer combobox
- Sort all the renderers in ascending order. (the fact that D3D11 was
above D3D9 really annoyed me >_<)
- Properly display usage of D3D10/D3D11 on the combobox.
- Use highest available version of DX by default.
- GSDX: gray out upscaling hacks at native resolution
- GSDX-PSX: Modifications to the dialog
- Add new logos
- Remove SDL renderer from combobox since it was removed long ago.
