Unknown W. Brackets 6e6535c263 softjit: Skip reading dst pixel where blended out. 
Sometimes used by blends used purely to multiply the source color by
something, usually prep for bloom.
 2022-09-24 02:00:03 -07:00
Unknown W. Brackets a4c3718431 softgpu: Optimize rectangle sampling/blending. 
Sometimes the vertex color or alpha can allow us to optimize away some
multiplication.
 2022-09-24 02:00:03 -07:00
Unknown W. Brackets 794a5c07ad softgpu: Ignore a needless color test case. 
This happens in Ridge Racer, and we can entirely skip the color test.

Henrik Rydgård d743bfac93 Merge pull request #16085 from unknownbrackets/softgpu-vert 
softgpu: Cache reused indexed verts
 2022-09-24 00:00:26 +02:00
Unknown W. Brackets 66b6dfd0a5 softgpu: Fix self-render detect in Ridge Racer. 
When we flush we mark all pending writes zero, but we rely on this being
set to detect self-render.

TRANSFORM_ALL was wrong as well, sometimes clearing BINNER_RANGE.

Unknown W. Brackets 88b3b26ed3 softgpu: Cache reused indexed verts. 
This happens a lot for spline/bezier, so can significantly speed up curve
heavy scenes.  Isn't necessarily that common otherwise, though.
 2022-09-22 18:27:59 -07:00
Unknown W. Brackets 067fac6817 softgpu: Skip matrix multiply for fog factor calc. 
We can just use a dot product instead, and always skip viewpos.
 2022-09-22 18:19:53 -07:00
Unknown W. Brackets 84a3f6de71 softgpu: Remove unnecessary state param. 
Oops, meant to remove this when refactoring imm prims.
 2022-09-22 18:18:49 -07:00
Unknown W. Brackets fc39f042ae softgpu: Avoid unnecessary flushing for curves. 
We don't need to flush all drawing between curves in softgpu, let them
queue up.

Henrik Rydgård 95ea0450fc Merge pull request #16066 from unknownbrackets/softgpu-fastrect 
softgpu: Narrow blend check for fast path further
 2022-09-21 10:01:04 +02:00
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 78a3925198 softgpu: Fix display framebuffer read. 2022-09-20 13:43:19 -07:00
Unknown W. Brackets 7483923d07 softgpu: Correct clear rect off by one issues. 2022-09-20 12:57:05 -07:00
Henrik Rydgård 85d1f28997 Throw in assorted warning fixes 2022-09-20 18:04:08 +02:00
Henrik Rydgård 1ae7c0132c Start unifying setting of the GPU feature flags, now that thin3d has feature detection. 2022-09-20 10:07:01 +02:00
Unknown W. Brackets e2929fb395 softgpu: Skip flushing on no change. 
Minor tweak, we sometimes try to flush even without anything to flush, and
were previously rechecking a lot of things.
 2022-09-19 08:38:11 -07:00
Unknown W. Brackets 259abf79dd softgpu: Skip more triangles with equal verts. 
Even if X is not equal, if all Y are equal, we can still skip.
This seems to happen more often than I expected with far away objects.

Skipping here avoids filling up the queue.
 2022-09-19 08:37:47 -07:00
Unknown W. Brackets 7d4aa3eb2d softgpu: Correct line early z checks. 
Was looking at completely wrong pixels, hadn't removed subpixels yet.
 2022-09-18 11:44:01 -07:00
Unknown W. Brackets ca248e1201 softgpu: Fix s8 primitives in throughmode. 
Also always cull no-position verts, hardware too.  Matches tests.
 2022-09-18 07:46:18 -07:00
Unknown W. Brackets 97002692c4 softgpu: Correct secondary color on imm verts. 
Only with through set, and we have to ignore position.
 2022-09-18 06:16:26 -07:00
Unknown W. Brackets 6877ff1af2 softgpu: Fix state/continuation for imm prims. 2022-09-18 06:16:26 -07:00
Unknown W. Brackets 596b07bd2e softgpu: Support fog and color1 on imm verts. 2022-09-18 06:16:26 -07:00
Unknown W. Brackets 35ba01e01f softgpu: Refactor imm draws to bypass vert read. 2022-09-18 06:16:25 -07:00
Unknown W. Brackets 799a9ae95b softgpu: Simplify vertex reading. 2022-09-18 06:16:25 -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 028a341cc8 softgpu: Explicitly flush on sync and output. 
We could in theory skip flush on FinishDeferred, and allow some CPU/GPU
overlap.  If we did, we'd still want to flush at these times.
 2022-09-18 06:16:25 -07:00
Unknown W. Brackets f740fcdbe7 GPU: Minor cleanup of unnecessary virtual. 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 8371091734 softgpu: Force correct alignment on 32-bit. 2022-09-12 22:15:02 -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.
 2022-09-12 21:57:00 -07:00
Unknown W. Brackets 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.

Henrik Rydgård 2791ab3226 Merge pull request #16011 from unknownbrackets/softgpu-rect 
Detect more triangles as rectangles in softgpu
 2022-09-12 08:35:13 +02:00
Unknown W. Brackets 3c9372fb75 softgpu: Ignore stencil test mask in ALWAYS mode. 
Small codegen improvement since we can directly use ref and avoid loading
the unmasked reference.
 2022-09-11 22:39:56 -07:00
Unknown W. Brackets 1f6870798b softgpu: Include early Z in func description. 2022-09-11 22:39:32 -07:00
Unknown W. Brackets 151727ee01 softgpu: Detect longer strips of rectangles. 
Could maybe even combine these into one large rectangle, but the main
benefit is avoiding triangles.
 2022-09-11 22:39:32 -07:00
Unknown W. Brackets 288d18447d softgpu: Detect full triangles as rectangles. 
Seen in a dump from Infected, improves FPS ~25% there.
 2022-09-11 22:39:32 -07:00
Unknown W. Brackets ce4fee7373 softgpu: Refactor triangle cull processing. 2022-09-11 22:39:32 -07:00
Unknown W. Brackets 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 8a2115be46 softgpu: Enable early Z tests a bit more often. 
This helps in cases where sfail doesn't matter.
 2022-09-11 18:39:39 -07:00
Unknown W. Brackets 5f2e20d8ca softgpu: Reduce some minor bin item field sizes. 2022-09-11 18:39:14 -07:00
Unknown W. Brackets 8c55e18ea8 softgpu: Switch vert continue buffer to members. 
Better this than static.  May be easier to handle imm prims correctly.
 2022-09-11 08:54:34 -07:00
Unknown W. Brackets e72309745e softjit: Implement accurate fog color blending. 2022-09-11 08:50:07 -07:00
Unknown W. Brackets 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.)
 2022-09-11 08:24:40 -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.

Henrik Rydgård d86127ac5e Merge pull request #15999 from unknownbrackets/softgpu-texsize 
softgpu: Clamp/wrap textures at 512 pixels
 2022-09-11 10:12:38 +02:00
Henrik Rydgård 04c02340f1 Merge pull request #15998 from unknownbrackets/softgpu-rect 
softgpu: Allow almost flat rectangles to go fast
 2022-09-11 08:54:04 +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.
 2022-09-10 21:24:19 -07:00
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.
 2022-09-10 20:23:09 -07:00
Unknown W. Brackets 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.
