b15c65540e Fix the new logic-op-in-shader on OpenGL and D3D11 
Also disable BlueToAlpha for now for Outrun and DiRT 2, it breaks the
water effect somehow. Will come back to it later.

4da2ca0935 Implement shader blending for D3D9 
This was easy, dunno why I never got around to it before..
I guess I didn't know about VPOS.

This does raise our minimum shader model requirement to ps_3_0.

f5e6754ac0 Special case depal lookups for Test Drive's strange usage. 
This implements the hack I suggested in #13355, where instead of first
reducing the color to RGB565 as the real game does, we just take each
channel at full precision and do the lookup according to the mask,
linearly filtering the palette.

This makes the game look a lot nicer and is also a small optimization,
but the hack is very specific so kinda ugly in a way.

2cb9e09ad3 Implement new discovery of a larger CLUT than we thought, plus non-shared CLUTs for 8-bit indices. 
Not sure yet what limitations apply, regarding using it for even more

f061eadc04 Initial implementation of 3D texturing through equal-size mips (see #6357) 
Vulkan-only currently, though all the other backends except ES 2.0
without GL_OES_texture_3d can support it with some work.

e52e9094ca Vulkan fragment shaders: Don't opportunistically emit "layout (early_fragment_tests)" 
The purpose of this is not really for optimization, it's to get a
specific behavior that we really don't care about. Drivers are pretty
good at getting this potential performance improvement automatically
if it's possible without changing the output.

git blame says I added it, heh.

Don't think it'll make much difference one way or another, though, but
trying to reduce complexity.

6b2dec91b5 Finish BlueToAlpha functionality 2022-04-30 18:17:17 +02:00
Henrik Rydgård
462972f7ea Add option to redirect blue to alpha if 565 mode is rendered and mask is 0x0FFFFF. 
This is used by several games to render to the alpha channel of RGBA4444
images, which cannot normally be done directly on the PSP.

Can be used as a far more efficient replacement for
ReinterpretFramebuffers/ShaderColorBitmask

960e2dac36 OpenGL fragment shader gen: Fix precision inconsistency for v_color0/1. 
Probably won't fix anything, just want this in for, well, consistency.

Noticed it debugging the iOS flat shading issues, but doesn't fix that.

Unknown W. Brackets
4006a4b143 GPU: Ignore color write mask if unusable. 
We unconditionally attempt to use a shader with color write mask, so we
can't just refuse to generate a shader - it'll mean non-supporting devices
get no shader at all.

It's better to continue ignoring the mask in that case.
