refractionpcsx2 effdfd5a22 GS/HW: Fix up some RTA behaviour and reduce copies 2024-04-02 21:48:32 +01:00
refractionpcsx2 059ec49389 GS/HW: RTA improvements and enhancements 2024-03-25 17:58:12 +00:00
refractionpcsx2 bfef8397d6 GS/HW: Allow source is rt to use corrected alpha in most cases. 2024-03-17 17:24:39 +01:00
lightningterror 3a2888a5d5 GS/HW: Adjust RTA shader precision. 2024-03-17 17:24:39 +01:00
lightningterror 0900c2fd8b GS/HW: RTA Correction, implement on DATE. 
Less copies, and makes it work with DATE.

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

refractionpcsx2 5dc27ed275 GS/HW: Convert depth16->rgba16 shader to integer 2023-10-01 21:08:39 +01:00
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.

lightningterror 3dce969a5e GS-shaders: Add missing copyright headers. 2023-07-21 10:24:15 +02:00
Stenzek 435e73d838 GS/HW: Texture cache improvements 
Change texture scale from vector to scalar

 - Independent X and Y scaling is long gone.
 - Also separate size and scale in TC lookup

Move clear value for texture to base class

Align heights to page size

 - Since FRAME and Z are in page units, we can't have two targets
 - overlapping within the same page.
 - Stops some small resizes too.
 - Test cases: Genji and Spider-Man 2 shadows.

Don't modify target TEX0 on shuffle/clear

Move upscale multiplier to uniform

Make P8 conversion page-aware

Fix incorrect depth preload shader

Improve HLE of texture shuffles

When a texture shuffle is split into two half-screen draws, we skip the
first, and draw the whole thing in the second, taking care of when both
the texture and framebuffer are offset.

TellowKrinkle 1ad6605dfb GS:HW: Remove comment on rgba to 8i only-blue optimization 
Doesn't seem to improve anything anymore (GPUs do this with csel now anyways, it's like 5 instructions with no divergence)

TellowKrinkle 9b5dd92dad GS:HW: Use 16-bit unorm for HDR 2022-10-11 18:17:27 +02:00
TellowKrinkle 73ae9f8879 GS:HW: Make HDR algorithm more float-precision-friendly 
- Use whole numbers instead of 255ths
- Use range -128 - 127 instead of 0 - 255 for accumulation blends

TellowKrinkle 91601e5647 GS: Manually do bilinear sampling when converting RGBA to depth 
Shader bilinear doesn't properly handle the case where r overflows into g (or g overflows into b, etc)
