Developed a new SW sprite render function, which is used to fix
Jak and Daxter colors in Jak games and to remove the old Jak games hack
which yielded wrong colors and clashed with TC search texture in RT function.
- Remove OO_JakGames hack for palette readback from framebuffer (slow,
clashes with texture in RT TC function, clashes with Target readback logic)
- Developed new method SwSpriteRender with CPU rendering logic
- Add OI_JakGames method using SwSpriteRender for CPU palette rendering (fast,
does not clash with texture in RT TC function, no readback required)
Bonus: fps also sees an improvement in Jak games 3-5 increase.
It will allow to render the shadows properly.
Rendering pattern is:
Save RG channel with a kind of a TS (replaced by a copy in this hack),
compute shadow in RG,
save result in alpha with a TS,
Restore RG channel that we previously copied to render shadows.
Typical shuffle case is 1/2 height so other half is undesired
In dbz we split the depth buffer.
- Sample first half, write to `0x0`.
- Sample second half, write to `0x800`
- Finally, sample `0x0` though `0xffc`
Crash Twinsanity is a similar case.
A short summary how d3d option behaves compared to gl.
None d3d-> behaves the same
Basic d3d-> even less than 1/3 of Basic opengl.
Medium d3d -> less than 1/3 of Basic opengl.
High d3d -> 1/3 of Basic opengl.
Note: Medium and High options are mostly intended for debug use.
It works on games such as Fifa Street 1 and 2 (character and stage
rendering), mission impossible operation surma (shadow rendering).
It needs at least Basic level of blending enabled on d3d11.
Idea is to disable multiple features in 1 option to avoid gui clutter.
Unscale Point and Line:
This partially reverts PR #2710 restoring Unscale Point and Line but as a disable option.
It can help Xenosaga games.
GS Memory clearning:
This disables GS memory clearing to be done on the CPU, by default both gpu and cpu do memory clearing
which is more accurate.
It can help Kingdom Hearts games.
The hack was used when depth emulation was not supported or when depth
is disabled.
It causes graphical glitches with the faces when depth is disabled.
And the time has come to say good bye (good riddance?), this build removes Direct3D9 entirely from GSdx. D3D9 is/was holding us back in some D3D11 fixes that we want to further implement.
The last build that supports D3D9 is v1.5.0-dev-2779-g1a61148b0 for anyone still interested.
"Press F to pay respect.
The hack caused glitches to appear on the right side of the screen, the hack was used as a workaround to properly display game ui elements however it is no longer needed on opengl and d3d11. The ui elements are rendered properly with Depth Conversion.
Shadow issues are solved with at least partial level crc hacks.
See https://github.com/PCSX2/pcsx2/issues/2692 for more detailed information.
It fixes a bunch of shadow/transparency issues.
Fast DATE doesn't rely on the gui option and is always on.
Confirmed fixed issues: Persona 3 shadows on d3d11,
Digital Devil Saga Transparency d3d9/11.
Fast accurate date works the same/similar to OpenGL.
Confirmed fixed issues: DBZ BT3 ground shadows, Fifa Street 1 shadows
on all d3d renders as well.
Also this option doesn't cause other transparency issues like the
Alpha Stencil hack.
Note: If Alpha Stencil is enabled Fast Date and Fast Accurate Date will
be disabled.
Note2: Full Accurate Date is not implemented so the code fallbacks to
Fast mode instead.

This will probably be the last feature d3d9 gets before getting purged.
Fixes right half screen issue on TalesOfLegendia. UI elements of the
screen are properly emulated with depth emulation on gl (possibly fixed
by
1cc696ab31).
Shadows will be glitchy if crc hack level is below partial level.
I'm not even sure if the hack is useful at all anymore since it
introduces issues now.
Issue #2692
This pull request is for the pending reorganization of the folder structure on GSdx,
making it better organized and easier to work with.
Also remove unused GSTextureFX.cpp file.
