596b07bd2e softgpu: Support fog and color1 on imm verts. 2022-09-18 06:16:26 -07:00
Unknown W. Brackets
1be5f1670c softgpu: Remove mostly unused screen offset state. 
This is now already cleaned up from coords, so no need to cache it.
 2022-09-12 22:02:10 -07:00

167213c746 softgpu: Cache texture bufws at 16 bit. 
Reducing the size of state a bit.

b2e6a086dc softgpu: Reduce size of VertexData texture coords. 
There's no real benefit to this with only two values.
Not much of a gain perf wise, but still good to transfer less data.

8a6e8066bf softgpu: Store vertex colors as packed RGBA8. 
No need to keep it expanded at 4x the space for both colors.

b90fc7137f softgpu: Correct accuracy of fog calculation. 
This matches values from a PSP exactly, with the help of immediate mode
vertex values (since this directly allows specifying the fog factor
without any floating point math.)

Merge pull request #15999 from unknownbrackets/softgpu-texsize 
softgpu: Clamp/wrap textures at 512 pixels
 2022-09-11 10:12:38 +02:00
Unknown W. Brackets
15d5fa48f7 softgpu: Check depth test early on simple stencil. 
If we don't need to write stencil on sfail/zfail, we can do the depthtest
early, which allows us to more often skip texture sampling.

This gives a good improvement in Chains of Olympus.

18c9a4d9c9 GE Debugger: Fix crash stepping with large tex. 
Some math was overflowing in allocations, and it would allocate zero
bytes.  Let's just refuse textures more actively.

7a83f8bab5 softgpu: Use vertType prim override for flags. 
These parameters are a real shame, was so clean before...
 2022-09-06 22:20:45 -07:00

3d52b445f1 softgpu: Restrict CLUT to proper size. 
We had 15 KB more space than needed before.

7389a36fad softgpu: Avoid unnecessary clearMode checks. 
Already baked into the flag.

Merge pull request #15411 from unknownbrackets/softgpu-range 
softgpu: Apply region x2/y2 as a scissor
 2022-02-20 21:42:00 +01:00
Unknown W. Brackets
1d0936ea79 Debugger: Improve drawing range in softgpu. 
We don't always want all of region, particularly if scissor is a regular
screen size.  This improves debugging in GoW.
 2022-02-20 12:21:48 -08:00
Unknown W. Brackets
ff5edb2bbc softgpu: Correct accounting for pixel center. 
Filtering is still not perfect but this makes different orientations
better.
 2022-02-20 10:50:59 -08:00
Unknown W. Brackets
e1eb4ba94a softgpu: Directly implement rectangle drawing. 2022-02-20 09:58:01 -08:00
Unknown W. Brackets
cc6491342e softgpu: Prepare dedicated rectangle path. 
We're still sometimes using the slow rect-as-triangles path, let's do
something faster.  As a first step, just handle binning.
 2022-02-20 09:38:51 -08:00

1bc3acf2ed softgpu: Use a const for subpixel screenpos factor. 2022-02-19 21:03:49 -08:00
Unknown W. Brackets
a66377fdf1 softgpu: Remove offset from screenpos. 
This simplifies tighter calculations, and reduces the common magnitudes
we'll be dealing with.

85cb4101dc softgpu: Cleanup todos on perspective correctness. 
Only the texture appears to be perspective corrected.  Color is simply
linear.

2479d52202 Global: Reduce includes of common headers. 
In many places, string, map, or Common.h were included but not needed.

76f9103e97 softgpu: Add a table and initial dirty flags. 
Not actually using the dirty flags to skip state, but have moved to
Execute_* functions and everything else like other graphics backends.
 2022-01-23 08:08:40 -08:00
Unknown W. Brackets
c0c3f7284a softgpu: Avoid flush texturing from stride. 
This generally detects overlap more accurately using a dirty rectangles
approach.  Also detects render to self much more accurately, including
with depth.

653c036ac8 Debugger: Fix crash in software renderer. 
The clut isn't set by sampler state, it's set normally by the binner.
 2022-01-16 21:53:55 -08:00
Unknown W. Brackets
2ad7d8ed29 softgpu: Fix alpha blend with one/zero. 
Wasn't setting the fixed value constants in these cases, so need to handle
in the C++ version.

970e9c2f51 softgpu: Move threading into BinManager. 
This threads much more effectively, across entire prim call.

d7a82ab7b8 softgpu: Compute func IDs once per batch of verts. 
This saves a decent chunk of time, especially when many verts are being
drawn.
