Gregory Hainaut a7ba779ba8 gsdx ogl: another HLE channel effect for terminator 3
Same as before but with a different fbmask value (I don't know why but
I have the feeling that I might need the others value too)

Unfortunately I think the game uses another similar effects

Gregory Hainaut 247d33a627 gsdx ogl: always clear depth buffer in FFX2
It avoid depth issues and I'm sure it won't broke other games this way.

Issue #1340

Gregory Hainaut e258f3e2fa gsdx ogl: update accurate DATE behavior
* Fast accurate DATE is always enabled, it was faster than standard DATE

* The less fast version is always enabled too. It is likely barely used
  so perf impact will be small on few game that could hit this path.
  Nice rendering has a higher priority

* The "slow" path will depends on the date option.
Note normally it isn't too slow (-10%) if GL_ARB_shader_image_load_store
is supported but AMD crimson is an epic fail.

Gregory Hainaut a4c7541092 gsdx ogl: tentative hack to make FFX go along with depth option
Issue1: Depth buffer is wrongly invalidated only the first page is detected.

Issue2: First page seems to be partially written. Could be a GSdx transfer bug.
Anyway, invalidation only support a page granularity.

So here a quick workaround that will clear depth buffer in case of very small partial write.

Might worth to check regression on nocturne/digital saga

Gregory Hainaut 30ce6b0a6a gsdx ogl: check debug function exists
I'm sure they exists in the openGL renderer context but there are
also used in common code. So potentially in DX context.

Gregory Hainaut 08f7bd2dc3 gsdx: add crc hack for Ar tonelico 2
It would requires some texture dynamic width convert shaders.
So as a quick solution, let's add a new CRC hack.

For issue #1362 (granted the CRC is correct)

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

Gregory Hainaut 5b061e062c gsdx ogl: replace ClearRenderTarget_i by glClearTexSubImage
Avoid state change, avoid potential texture buffer reallocation

Note: require GL_ARB_clear_texture

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.

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

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
