6558bde0f6 Remove SmoothedDepal compat setting, instead detect the ramp directly. 2022-08-22 15:24:41 +02:00

e374ea6b21 GPU: Restrict mip CLUT enhancement a bit. 
Can't replicate this behavior on a real PSP.

In case a game sets the separate CLUT flag by accident, ignore except
in a safe case that occurs in Misshitsu no Sacrifice.  See #15727.

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
16-bit colors, etc...

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.

04a85b1da0 Allows "merging" render targets that overlap on the Y access. Fixes #7295 (Juiced 2) 
To be safe, gating this behind the related AllowLargeFBTextureOffsets,
which is also required for the effect to work.

Additionally, fixes the offset check for X offsets, which I guess is a
very small risk.

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

2797e035df softgpu: Precompute lighting parameters. 
In many cases, games use lighting just for diffuse or something, this
helps skip what's not needed too.  Good improvement in a scene from a
Naruto game.

f3ebd6553d Turn off vertex range culling in bezier/spline calls. 
When we do lower res tess than the real PSP, we cant trust the game to not cause range culling to kick in.

3d289594f9 ShaderBlend and FramebufferRead are separate concepts. Reflect that in naming. 
The former has forms that don't need to read the framebuffer.

This exposes that some logic is wrong...

eadd3c5785 Remove the LARGE_VIEWPORTS separate path. The fewer paths the better, all need to work anyway. 
Required fixing a bug in ShaderUniforms.cpp (used by D3D11 and Vulkan,
the two backends that previously exposed LARGE_VIEWPORTS).

0462c01228 Workaround ARM Mali depth hardware bug. Fixes #11937 
When triangles coincide with the Z=1 plane in specific ways, triggered
by Burnout Legends' sky for example, the depth buffer gets corrupted.

This is worked around here by slightly rescaling Z. This type of
workaround is recommended by ARM driver engineers.

Ugly but what can you do when the hardware is bugged. I've done quick
tests on a number of games with no issues.

77f0499f7f GPU: Rename clipping flag to depth clamp. 
It seems to just to depth clamp.  When depth clamp happens, it affects
clipping a little, but only for vertices that needed clamping.
