596b07bd2e softgpu: Support fog and color1 on imm verts. 2022-09-18 06:16:26 -07:00

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.

7a83f8bab5 softgpu: Use vertType prim override for flags. 
These parameters are a real shame, was so clean before...

653c036ac8 Debugger: Fix crash in software renderer. 
The clut isn't set by sampler state, it's set normally by the binner.

d6fa301ab1 softgpu: Track CLUTs as states for binning. 
This way we can have multiple CLUTs in process at once, which helps.

edb79d968f softgpu: Cache CLUT params in sampler state. 
And now there's no more gstate for pixel drawing or sampling.  Just a
little left in rasterization.

c0e85e6170 softgpu: Move texenv color into sampler state. 2022-01-15 17:52:40 -08:00

ad3635c82a softgpu: Move tex size to cached state. 2022-01-15 17:22:43 -08:00

092b03bd67 softgpu: Move fixed blend factor to draw pix state. 
This is the last of the gstate.

f4f7ea2736 softgpu: Cache colortest params in draw pix state. 2022-01-15 13:03:11 -08:00

aa9d751248 softgpu: Cache alpha/stencil test masks in state. 2022-01-15 13:03:11 -08:00

acad2640dd softgpu: Cache logicOp in draw pixel state. 2022-01-15 13:03:10 -08:00

f1ce2e7715 softgpu: Cache minz/maxz in draw pixel state. 2022-01-15 13:03:10 -08:00

e9f3720e20 softgpu: Cache fog color draw pixel state. 2022-01-15 13:03:10 -08:00
Unknown W. Brackets
880826bab4 softgpu: Remove disable of cached pixel state. 
That mode is slower now (with the other state changes), and we don't want
to read gstate anymore anyway.

2aa57679fa softjit: Keep mip S/T calc in SIMD. 
This is only a tiny bit faster, though.

5e3bef7e14 samplerjit: Avoid gather if overread could crash. 
This should be rare, but a game could easily shove a CLUT4 texture at the
end of VRAM, and then accessing the last index would segfault.

355bad666c softjit: Optimize common case bloom blending. 
Bloom often uses fixed ONE + ONE, which is a lot less work for us.  And
bloom often runs over and over again on pixels, so saving work is good.

06e954fe2a samplerjit: Create a separate fetch func. 
This allows nearest to become more similar to linear, where it applies the
texture function.

3bc6009158 samplerjit: Refactor sampler ID calculation. 
Make it the same as pixel func IDs.

476dfdf731 samplerjit: Add more bits for S/T, skip multiply. 
For now, we're not using those other bits yet.

aec41b34d6 softjit: Reduce ditherMatrix to 8-bit. 
Oops, not sure why I made it 16 bit.

Unknown W. Brackets
1f9dc3a568 softjit: Precalculate write mask and dither. 
This is slightly abusing PixelFuncID, but the intent is to provide some
memory that's easily accessible from the jit func, but still associated
with that calculation (i.e. not global.)

876c8cd368 softgpu: Fix PixelFuncID size. 
Oops, can't use unions in bitfields.  Also improve typesafety.

28bc91bd79 softgpu: Add func to tersely name pixel funcs. 2021-11-21 08:23:32 -08:00

f7a31c992d softgpu: Use pixel func ID to draw pixels. 
This just reduces reliance on gstate directly, and should help keep things
consistent.
 2021-11-20 15:27:04 -08:00
Unknown W. Brackets
953200c995 softgpu: Add func to calculate pixel func ID. 
This normalizes some things, and eventually can be used for a jit key.
