lightningterror 67d7744f7f GS/HW: Further expand blend multipass. 
For formulas:
Cs*Alpha + Cd*(1 - Alpha).
Cd*Alpha + Cs*(1 - Alpha).
Where Alpha is higher than 1 and is either As or Af.

lightningterror 40d5c78573 GS/HW: Implement PABE(Per pixel alpha blending) on accumulation blend and add optimizations. 
PABE accumulation blend:
Idea is to achieve final output Cs when As < 1, we do this with manipulating Cd using the src1 output.
This can't be done with reverse subtraction as we want Cd to be 0 when As < 1.
Blend mix is excluded as no games were found, otherwise it can be added.

PABE Disable blending:
We can disable blending here as an optimization since alpha max is 128
which if alpha is 1 in the formula Cs*Alpha + Cd*(1 - Alpha) will give us a result of Cs.

lightningterror 75defbeded GS/HW: Adjust point sampler behavior. 
VK/GL/Metal: Get rid of it completely as it doesn't seem needed anymore.
DX: Only enable it with combination with GPU Palette Conversion enabled as that's when the issue occurs.

Test: See if Metal breaks with no point sampler.

lightningterror abec2738b9 GS/HW: Extend blend second pass to more blend formulas v2. 
Cd*(1 + Alpha).

Stenzek 7ddf6386f1 GS: Remove DSB feature

Stenzek a317e9c038 GS/HW: Improve accuracy of RGB_ONLY AFAIL 
Instead of breaking the draw into two passes, which breaks when
fragments overlap each other and blending is enabled, use blending to
leave the value of Ad intact when a pixel fails the alpha test.

In the case of DATE being enabled, prefer PrimID over stencil, as since
we are changing Ad on a per-fragment basis, with some fragments not
being modified, stencil DATE will become desynchronized with the value
of Ad.
 2024-03-28 11:46:20 +10:00
Stenzek 0917d49a01 GS: Remove separate alpha pass fallback 
This is just wrong when overlap and depth writes are involved.

lightningterror 0900c2fd8b GS/HW: RTA Correction, implement on DATE. 
Less copies, and makes it work with DATE.

lightningterror 58628b8dd3 GS/HW: Make sure we don't multiply Cs if Ad is corrected. 
Another potential to avoid copies.

lightningterror 71376ff4e6 GS/HW: Decorrect Ad on sw blend in tfx shader. 
Otherwise if we do decorrection in covert shader we add more copies.

Also make sure to decorrect for fbmask, tex is fb.
 2024-03-17 17:24:39 +01:00
lightningterror 6c9f132093 GS/HW: Add support for Ad (RTA) correction. 
The idea is to adjust the alpha destination for more
accurate hw blending which will work on all renderers.

Old behavior has Ad in range within 0-1 whereas for blending 0-2 is needed.

copy rt -> adjust the alpha -> copy back the adjusted alpha-> restore old alpha after blending is done
 2024-03-17 17:24:39 +01:00
lightningterror a7c5eebf99 GS/HW: Adjust blend mix for impossible blend. 
Since we can't do Cd*(Alpha + 1) - Cs*Alpha in hw blend what we can do is adjust the Cs value that will be subtracted,
this way we can get a better result in hw blend. Result is still wrong but less wrong than before.

lightningterror f96e7a9156 GS/HW: Rename dfmt to dst_fmt. 
It was confusing whenever the d meant depth or destination, this should make the code easier to read.
 2023-10-19 19:25:13 +02:00
lightningterror 846c9cec6a GS/HW: Adjust how we handle RT alpha in blending. 
When both rt min and max are equal then we know what Ad value is,
if so use Af bit instead and set AFIX value from rt alpha value that we know.

On OpenGL when BLEND C == 1 but reading the rt is disabled, set the value to 0 instead
of reading an undefined value.

Stenzek d70334ee57 GS/HW: Slight shader simplification 
- Don't declare texture if it's not read from. Stops Vulkan validation
   layers whinging.

 - Get rid of OpenGL common_header.glsl, and use name linking instead of
   leftovers from separate shader objects.
