Stuart Kenny 217e1c8fae GS: Update lottes crt shader. 2024-09-19 17:51:29 +02:00
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 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.

refractionpcsx2 effdfd5a22 GS/HW: Fix up some RTA behaviour and reduce copies 2024-04-02 21:48:32 +01:00
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.

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

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.

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.
