TellowKrinkle cb64e8d504 GS:HW: More accurate blend equation for blend mix 2022-08-13 00:01:23 +02:00
lightningterror 6b48cf574d GS-hw: Adjust how we handle specific blend mix cases. 
Replace Cs*As + Cd*(1 - As) with Cs*As - Cd*(As - 1).
Replace Cs*F + Cd*(1 - F) with Cs*F - Cd*(F - 1).
As - 1 or F - 1 subtraction is only done for the dual source output (hw blending part)
since we are changing the equation.
Af will be replaced with As in shader and send it to dual source output.

Also check if A*Alpha in the shader overflows, if it does then adjust the
alpha that is sent for HW blending further to compensate.

lightningterror b8236b1b1c GS-hw: Partially revert #5540 
Allow to wrap on colclip.
For real tho, ideal solution is sw blend, doing any clamp/wrap is wrong on blend mix.
 2022-02-19 00:38:13 +01:00
lightningterror 1a3d77b2c0 GS-hw: Fix d3d11 depth sample shader.

lightningterror 06766ddb98 GS-hw: Don't wrap on 16bit destination format for blend mix. 
Helps Dog's Life blending, we shouldn't wrap as we do more blend math afterward which will be wrong if we wrapped before.

refractionpcsx2 ad415945a6 GS-hw: Apply clamp/wrap when FBMask enabled 2022-02-11 19:33:38 +01:00
Connor McLaughlin 2684fd6b62 GS: Add depth copy convert shader 2022-02-03 15:20:35 +00:00
lightningterror 3ca4272230 GS-hw: Implement hw, hw/sw, sw blending on Ad when alpha write is masked. 
Idea is to replace Ad with As when alpha write is masked,
then expand/let blend mix, accumulation blend non recursive blend or hw clr blend to
do the blending with Ad swapped as As.

We are doing this to try to bring some originally higher blending modes to lower levels
where we can do the draws with less texture barriers instead (gl/vk),
as for d3d11 this allows to run blending on the draws since previously the cases weren't handled properly,
it will be slower on d3d11 since we will be reading the frame buffer but it's better than nothing.

D3D11: It is enabled on Medium blending or higher, if draw is fbmask then it will enable
it on basic blending too.

OpenGL/Vulkan:
It is enabled based on the previous blending modes:
accumulation blend -> either minimum or basic level, depending on colclamp.
non recursive blend -> either minimum or basic level, depending on colclamp.
blend mix -> basic and higher level.
hw clr blend -> minimum and higher level.

All:
Prefer full sw blend when primitives don't overlap, sw fbmask or full barrier is used, it is more accurate.

lightningterror ae14afd5f7 GS-hw: Combine BLEND_C_CLR2_AF and BLEND_C_CLR3_AS in one shader bit. 
Free a shader bit.

TellowKrinkle 6d0b9b3747 GS:HW: Don't scale rt when converting to texture 
Scale texture coordinates instead

Connor McLaughlin f33ee27f56 GS: Get rid of extra binding for channel shuffle 
Having this binding was redundant, as there's no "normal" texture
sampled when we're doing a channel shuffle, and it caused issues in
Vulkan when the render target or depth buffer the source.

Also fixes the Urban Chaos HLE shader.

Fixes validation errors in GT4, NFS: Carbon, Urban Chaos, probably
others too.

lightningterror 3b691da8d1 GS-hw: Implement alternative hw blending for Cs*Ad, Cs*Ad + Cd, Cd - Cs*Ad. 
Alpha destination value is wrong so let us try to compensate.

Multiply Cs by (255/128) in shader.
Will work best if Cs is 0.5 or less,  if it's higher than 0.5 then the closer to 1 the less accurate it gets.

Ofc it is best to use sw blending but it will help if sw blending is not present/selected for specific draw, will help d3d11 quite more.

lightningterror c9216e5625 GS-hw: Remove useless shader line from CLR As/Af case. 2022-01-24 11:42:54 +01:00
lightningterror 93af9656d0 GS-hw: Fix clr 1 case shader. 
Forgot to rename.
 2022-01-24 11:11:38 +01:00
lightningterror 4ab9d1a493 GS-hw: Implement alternative hw blending for Cd*As, Cd*F. 
Do hw blend for Cd*As, Cd*F, expand the clear color blend method as it is almost the same.

Most helpful for dx11 ofc, for gl/vulkan will help with rendering on lower
levels of blending without needing a barrier.

lightningterror 3c92054a6e GS-hw: Move PABE shader bit to the top of sw blending. 
Early return when there is no sw blending, no need to run the blend code.
Optimization.

lightningterror 6a431daffc GS-hw: Extend Blend mix to work when alpha is higher than 1. 
Clamp the alpha(As/Af) to 1 in the shader, it is already clamped to 1 in hw blend unit.
It should allow to better render the effects, still not fully accurate but it's closer to what we want.
Hopefully it helps D3D11 more.
