6282f8b05f softgpu: Expand texture coords to include q. 
We'll need this to correctly project.

8376176b2f softgpu: Split clippos out of rasterization vert. 
We don't use it, except w, at all in rasterization, so no need to keep it
in the bin queue.

c47d7eab38 softgpu: Simply 5551 blending fast path. 
Since it only supports multiply and add, let's just stick with that.

1eeb4f0bcf softpu: Refactor out 5551 fast path checks. 
They were duplicated, and better to organize them according to state.

f30b1d048d softgpu: Avoid fast path in another wrong case. 
Seen in Kurohyo.  Missed that the alpha blend check essentially means only
standard blending can work.
 2022-09-24 17:53:09 -07:00
Unknown W. Brackets
cefef3b4f9 softgpu: Narrow blend check for fast path further. 
See #15756, frame was largely black because of a full screen blend
rectangle intended to brighten the screen slighty (I assume.)
 2022-09-20 14:29:33 -07:00
Unknown W. Brackets
de080e2594 softgpu: Simplify vertex range culling. 
The previous logic was harder to understand and easier to get wrong.
Just drop them when clipping the primitive.
 2022-09-18 06:16:25 -07:00
Unknown W. Brackets
9b01fce5b5 softgpu: Run early Z tests in fast rect path. 
Needed for some 2D games, like Criminal Girls.
 2022-09-17 13:37:54 -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
Unknown W. Brackets
167213c746 softgpu: Cache texture bufws at 16 bit. 
Reducing the size of state a bit.

Merge pull request #16011 from unknownbrackets/softgpu-rect 
Detect more triangles as rectangles in softgpu

288d18447d softgpu: Detect full triangles as rectangles. 
Seen in a dump from Infected, improves FPS ~25% there.

8a6e8066bf softgpu: Store vertex colors as packed RGBA8. 
No need to keep it expanded at 4x the space for both colors.
 2022-09-11 18:41:06 -07:00
Unknown W. Brackets
2e3b73abaa softgpu: Restrict sprite fast path to throughmode. 
Its UV checks already should have generally, but let's be safe.  It
doesn't validate state like fog, etc.

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
90e009edb9 softgpu: Clamp/wrap textures at 512 pixels. 
A texture larger than 512 is "valid", but simply wraps/clamps at 512.
Importantly, the texture coords are still calculated at the specified
size, which can be up to 32768.

f5f5c9ea87 softgpu: Avoid calling unordered coords tl/br. 
These are just corners, we don't know if they're top or not at this point.
 2022-09-10 14:58:27 -07:00
Unknown W. Brackets
13ca08b235 softgpu: Avoid over-aggressive rect conversion. 
The TL and BR have to match between UVs and pos, not enough for UV to be
in order.  This was causing an artifact on Chains of Olympus' title.
 2022-09-10 14:56:13 -07:00
Unknown W. Brackets
e7d49cd7d0 softgpu: Allow almost flat rectangles to go fast. 
Improves transform rectangles used in Chains of Olympus, for example on
the title screen.
 2022-09-10 13:29:40 -07:00
Unknown W. Brackets
6004d4a459 softgpu: Refactor duplicate rectangle compat check. 
This just moves the logic to a single place for changes.

a91219bebc The Darkstalkers subpixel check should be == 0. Fixes #14953 again 2022-09-05 19:12:45 +02:00
Unknown W. Brackets
15b73b56bb softgpu: Correct texture check in fastpath. 
This is the no textures option, so we shouldn't check sampler state at
all.  Presumably this was failing and reading uninitialized data...
 2022-09-03 11:21:14 -07:00
Unknown W. Brackets
af004dd53d softgpu: Validate alpha test properly for fastpath. 
We don't want a weird LESS test being mishandled.
 2022-09-03 11:19:24 -07:00
Unknown W. Brackets
ba1ced4992 softgpu: Avoid rect fast path with subpixel offset. 
It doesn't handle it right, see #15876.  We still handle these with
DrawRectangle(), which gets it right.
 2022-09-03 11:08:11 -07:00

6737d69f0a softgpu: Cleanup some now unused state. 2022-02-20 09:19:48 -08:00
Unknown W. Brackets
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.

3d4c1548b6 softgpu: Allow tri -> rect in transform. 2022-02-12 12:03:55 -08:00
Unknown W. Brackets
259b10d42a softgpu: Turn more tri strips into rects. 
This catches a common case in Valkyrie Profile.
Rotation is resolved by just always using tl/br.
 2022-02-12 11:33:42 -08:00
Unknown W. Brackets
2381f355c2 softgpu: Combine tris to rects with ignored z too. 2022-02-12 11:33:36 -08:00
Unknown W. Brackets
2479d52202 Global: Reduce includes of common headers. 
In many places, string, map, or Common.h were included but not needed.
 2022-01-30 16:35:33 -08:00
Unknown W. Brackets
3010cd56d1 softgpu: Correct simple rectangles with mipmaps. 
Might be used for fonts, we could potentially check for bias/slope, but
mipmaps are uncommon in direct through draws anyway.
 2022-01-23 12:26:58 -08:00
Unknown W. Brackets
6896a7a64e softgpu: Use cached state for screen offset. 2022-01-15 18:20:25 -08:00
Unknown W. Brackets
02c5559393 softgpu: Remove z from DrawingCoords. 
It's not really used much of anywhere, anyway.

a228b2ab6c softgpu: Use cached sampler state outside jit. 2022-01-15 15:26:26 -08:00

0b3f096c01 softgpu: Cache strides in draw pixel state. 2022-01-15 13:03:10 -08:00
Unknown W. Brackets
970e9c2f51 softgpu: Move threading into BinManager. 
This threads much more effectively, across entire prim call.
 2022-01-13 22:45:23 -08:00
Unknown W. Brackets
48ef4a18b1 softgpu: Handle scissor/range in BinManager. 2022-01-13 19:07:41 -08:00
Unknown W. Brackets
a0a9b1e89b softgpu: Add class to manage and enqueue for bins. 
For now, just forwarding.
 2022-01-13 09:26:59 -08:00
Unknown W. Brackets
6839aac109 Debugger: Cache list PC for softgpu tagging. 
Still slow, but improved.

Unknown W. Brackets
d5c5e9478e softgpu: Prepare more state per prim call. 2022-01-10 22:12:35 -08:00
Unknown W. Brackets
9ec7d65c49 softgpu: Use func IDs instead of gstate more. 2022-01-10 22:12:35 -08:00
Unknown W. Brackets
d7a82ab7b8 softgpu: Compute func IDs once per batch of verts. 
This saves a decent chunk of time, especially when many verts are being
drawn.

 2022-01-02 18:11:07 +01:00

a259761262 samplerjit: Use nearest func in fast path too. 
This uses the more optimal tex funcs.
 2022-01-02 08:48:16 -08:00
Unknown W. Brackets
496545e55c softgpu: Add code for tracking GPU writes. 
Unfortunately, it has a pretty noticeable speed impact, even at the basic
"assume everything's written" level.  Compiled off by default, but at
least it's there.

Doesn't account for tests (i.e. alpha test skipping write) so still not
perfectly accurate.
 2022-01-02 08:28:30 -08:00
Unknown W. Brackets
06e954fe2a samplerjit: Create a separate fetch func. 
This allows nearest to become more similar to linear, where it applies the
texture function.
