73460f7461 softgpu: Correct accuracy of MODULATE texfunc. 
This matches hardware tests for every value of A * B.
Interesting that it's a different formula than alpha blend.

891fa8c613 softgpu: Template away uncommon mip usage. 
Improves general case about 10%.

48e9404419 softgpu: Remove useless switch by UV gen mode. 
They're all handled earlier now, and the switch is on a value & 3, so the
default wasn't even possible.

96a7554053 sofjit: Move common types to reg cache header. 
This makes it easier to use vectors elsewhere.

ce5ae95854 softgpu: Correct alpha blend subtract on negative. 
Oops, we need to subtract signed, but then clamp to unsigned.

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

09dc38080a softgpu: Move draw pixel code to separate file. 
This separates things better anyway.  No major perf impact.

Merge pull request #15154 from unknownbrackets/softjit

e2f0713cc2 softgpu: Clamp and round fog by mantissa bits. 
This matches hardware calculated fog values much better.

f7a31c992d softgpu: Use pixel func ID to draw pixels. 
This just reduces reliance on gstate directly, and should help keep things
consistent.

babd63c644 softgpu: Tune thread minimums better. 
Darkstalkers seems more sensitive to these than many other games, this
improves performance more.

fe440d40e5 softgpu: Clip full weighted Z without truncating. 
In case wsum_recip is nan or similar, we want to make sure we still
properly clip to minz/maxz.

f03fa2b0b8 softgpu: Improve accuracy of line drawing. 
Needs higher precision to change pixel at the right time.

This makes the lines in Persona 1 look right, see #3871.

7addc18a6b softgpu: Avoid overflow infinite loop. 
For certain large values, it would overflow and continue looping
endlessly.

3be5c7bd9a Make the minimum items per thread explicit. Found some bugs, optional arguments are evil. 2021-06-12 21:21:28 +02:00

4178f09e57 Build: More consistently avoid _M_ defines. 
We use PPSSPP_ARCH in several places already, this makes it more complete.

fb3ad1df4b Replacement: Read in texture filtering overrides. 
If you're replacing, you can know more information about linear safety for
tests.

3055deeba6 GPU: Fix some case warnings. 
Better to avoid the warnings.

c5e0b799d9 Remove category from _assert_msg_ functions. We don't filter these by category anyway. 
Fixes the inconsistency where we _assert_ didn't take a category but
_assert_msg_ did.

1b9440611a softgpu: Fix texture overlap. 
Mainly happened when we had wide textures and split them up between GPUs.

f1dfb25427 softgpu: Correct clear/solid rect BR corner. 
The scissor is inclusive, not exclusive.

c7f6724f7e Detect sprite drawing (1:1 texture mapping), run a simpler function without the triangle state tracking. 
This will allow further simplification and specialization.

7412e13767 SoftGPU: Implement dithering. 
Note: it applies even in 8888, so it can be used as a slight brightness
adjustment.

0b48c6d066 SoftGPU: Apply color doubling only to RGB. 
Broken in #11379 - accidentally applied to the alpha value.  See #11901
for an example where this caused issues with blending.
