6b20c0318d softgpu: Correct matrix value update wrapping. 
The values read back when saving a context or getting matrix data are set
differently than the actual values used for rendering.

This implements the wrapping and bleeding between matrices within softgpu,
but leaves hardware rendering to only use the rendering registers for
speed.

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.

34a8056017 GPU: Correct normalized zero normal proj map. 
Unlike lighting, this does not use 0, 0, 1.

b3c0f177e2 softgpu: Save last tc/normal in vertex reading. 
Matches PSP behavior, reusing last set values.

softgpu: Avoid waiting for a thread to drain

24560eef5c softgpu: Avoid waiting for a thread to drain. 
If we can, we want to keep the thread queues healthy, but not full.
Reduce the amount we push on a typical drain to avoid the Wait().

1aa6841759 softgpu: Increase queued prims. 
We made them smaller, so we can queue more of them in the same space.
Helps a little bit.

444781c7b0 softgpu: Fix triangle strip with partial rects.

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.

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.

a4c3718431 softgpu: Optimize rectangle sampling/blending. 
Sometimes the vertex color or alpha can allow us to optimize away some
multiplication.

794a5c07ad softgpu: Ignore a needless color test case. 
This happens in Ridge Racer, and we can entirely skip the color test.

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.

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.

84a3f6de71 softgpu: Remove unnecessary state param. 
Oops, meant to remove this when refactoring imm prims.

fc39f042ae softgpu: Avoid unnecessary flushing for curves. 
We don't need to flush all drawing between curves in softgpu, let them
queue up.

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.)

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.

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.

7d4aa3eb2d softgpu: Correct line early z checks. 
Was looking at completely wrong pixels, hadn't removed subpixels yet.

ca248e1201 softgpu: Fix s8 primitives in throughmode.

97002692c4 softgpu: Correct secondary color on imm verts.

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.

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.

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.
