8271ec1a55 softgpu: Avoid a divide by 0 in line interpolation. 
Fixes crash in Persona 2 loading screens.

74c1b21b59 softgpu: Don't redraw every pixel of a line 16x. 
Fixes the insane slowness when processing lines.  Now it's just regular
super slow.

4bb6a77519 softgpu: Cleanup DrawPoint a bit. 
Mostly in DrawSinglePixel() now.

8f5fc4f079 softgpu: Interpolate/texture lines and points. 
Also, expand out pixels in lines, it's just too slow otherwise (30%
overhead or so.)

e216032a8c softgpu: Separate out texturing logic. 
This way it can be applied to other primitives.  But, this will probably
need larger changes to implement mipmapping.

4c25bb0365 softgpu: Let's try doubling before alpha blend. 
Fixes #5122.

01090f4ce7 softgpu: Respect the texture filering option. 
Nearest is much faster, so you can force it to nearest for a good boost in
speed.

b9f4cc4481 Double colors only when texturing, and after test. 
Per tests.

eb0ea71f24 softgpu: Use region for debugger buffer previews. 
It's fine if it resizes or etc., but this should generally be the
interesting area of vram to show, without any confusing noise on the
side/etc.

9f86959826 Fix typesafety (ScreenCoords not DrawingCoords.) 2013-12-29 12:59:26 -08:00

9aa1b15569 softgpu: Fix black objects with bilinear filtering. 
Dividing by 256 gives us a range of 0-253, and incorrectly gets zero for
some components (guessing alpha, primarily?) in some games.

Dividing by 255 has a speed hit, so a slight bias to the top left seems
like a decent performance compromise (and it's a very slight bias.)

96d6f52a13 softgpu: Retain accuracy in depth for tests. 
Fixes intro/menu issues in Phantasy Star Portable 1/2, and text in the
first, both of which now look correct.

6ca5662b03 softgpu: Properly swizzle 16 bit textures. 
Fixes for example the graphics in Fieldrunners.

2f0c8c2877 softgpu: Attempt to implement GE_PROJMAP_UV. 
Looks okay, not sure if it's fully correct.

bd1d4e2d92 As if softgpu wasn't slow enough already, implement bilinear filtering. 2013-12-09 01:44:23 +01:00

637a9de75d Optimize out some clear mode checks. 
Since it's really common and the rasterizer is slow for large draws.

598d509fb9 Use multiple threads if available for softgpu. 
VIVA OVERHEAD.  But it's actually generally faster this way, even with
only 2 cores running (but not a huge improvement then.)

On an i7, this improves things ~2.5x with 8 cores.

7a9fe955f8 softgpu: Only check clear mode once for depthtest. 
Small, small optimization.  It's only called outside clear mode.

dfadb67ea1 Avoid some operator overloads. 
Causing ambiguity.

1311d71455 softgpu: Fix reversed stencil test funcs. 
LESS applies to the ref compared to the stencil, not the stencil compared
to the ref.

With this, stencil testing is finally being done properly in Star Ocean.

2db98b8669 softgpu: Don't apply logic op to stencil value. 
Also, they were not at all applying correctly.

21deaef35a Invert gstate.getClearModeColorMask(). 
It makes more sense matching gstate.getColorMask().

b9811c7c97 Use the slow way to get the softgpu texture. 
So that it actually shows what the softgpu is using.

5c2d418d95 Read softgpu stencil using existing funcs. 
Slower but at least it's the same.
 2013-10-07 01:02:58 -07:00
Unknown W. Brackets
b9453f82ca Use the full alpha bits for stencil in softgpu. 
It works to increment and set the stencil, so it can't be high bits only.
