Fixes FXAA being broken after b706c25b68.

Will be slightly difference since this is using the BT.709 coefficients
instead of CCIR 601 - but it matches the non-gather codepath now.

sideprojectslab f10e7f4ab7 GS: Implemented Motion Adaptive Deinterlacing for all renderers 
implemented FastMAD motion-adaptive deinterlacing for OpenGL renderer, other renderers will crash. FastMAD is replacing blend (either mode) so select blend to activate MAD under the hood

fixed an assert and assessed that one MUST select mode Blend bottom field first to enable MAD

removed forced mode 2, added separate motion thresholds for current field and alternate field motion and optimized MAD for Top-FIeld-First mode

committing kind-of broken status for review

the algorithm works well on most games, but somehow Kingdom Hearts works at half resolution

completely fixed weird artifacts on MAD, I only need to fix a 1-line offset that is causing the top of the screen to flicker

fixed flicker on first line, I still need to fine-tune some coefficients

solved all nastiness by realizing that MAD MUST work on an even resolution, so odd resolutions are rounded up. Now all games I tried look great

made MAD sensitivity adjustable inside GDDevice.h and passed to shaders as a parameters. For this purpose ZrH is now a vec4 to hold more parameters conveniently

ported MAD to DX11 and DX12

removed rounding of texture size to closest multiple of 2 and fized odd number of lines inside the shaders by also passing the vertical resolution as a parameter

improved compatibility of upper buffer offset adjustment for odd resolutions

added Vulkan support

lightningterror abcbdc4a25 GS-hw: Further improve how we handle blend mix 1. 
Compensate slightly for Cd*(As + 1) - Cs*As.
Try to compensate a bit with substracting 1 (0.00392) * (Alpha + 1) from Cs.
The initial factor we chose is 1 (0.00392) as that is the minimum color Cd can be, then we multiply by alpha to get the minimum blended value it can be.

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 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.

Scale texture coordinates instead
 2022-02-01 01:24:35 +00:00
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.
 2022-01-30 14:17:12 +00:00
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 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 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.
