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).
Alpha = As, Ad or Af.
For As or Af case when alpha > 128.
For Ad case when there is no RTA correction.

Stenzek fe0e71f586 GS/Vulkan: Drop feedback loop extension
Apparently this causes GPU crashes on RDNA3, and didn't provide any
tangible benefit for NVIDIA.

I'll replace this at some point with dynamic rendering local reads,
either before or after the GPUDevice transition.

lightningterror d824ae6e0c GS/HW: Extend blend second pass to more blend formulas.
`Cs + Cd*Ad, Cs - Cd*Ad, Cd*(1 - Ad), Cs*(1 + Ad), Cs*(1 - Ad).`

lightningterror 7dd7345e08 GS/HW: Minor shader optimization.
Use saturate instead of min max, saturate is faster than min max.

refractionpcsx2 30f4e77b31 GS/HW: Rearrange color on shuffle if SW Blend or TFX 2024-04-08 12:09:30 +01:00
lightningterror b1f4f67130 GS/HW: Add support for blend second pass.
Allows us to blend Cd with full alpha range of 0-2 bypassing hw blend limitations.
Not all Cd cases are covered, but it's a good start.

Also allows us to do Ad cases where we can double the blend to get the
proper blend result since Ad range is 0-1 instead of 0-2.

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.

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.

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

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.

GS/VK: Make sure feedback loop is enabled for SW_AD_TO_HW blend. (#10225)
Fixes Colin McRae Rally 2005 on Vulkan.
Possible others as well on basic blend with barriers or Medium blend with barriers disabled.

Bump shader cache version.

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.

refractionpcsx2 5dc27ed275 GS/HW: Convert depth16->rgba16 shader to integer 2023-10-01 21:08:39 +01:00
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 ff9ca059c7 GS/DX11: Require feature level 11.0
Feature level 11.0 GPUs were first released in 2009, almost 14 years ago
now. Older GPUs have not had drivers released in a long time, and are
known to be buggy.

None of us have hardware this old, so it's impossible for us to support
it.
