41209eb936 Stencil-to-alpha fragment tweak: Set alpha to 0 if we can't deduce the stencil value. 
This fixes the weird glowing shadows in Wipeout.

44beebf6b0 Realized it's ok to combine the stencil-to-alpha with alpha testing as it's done within the shader, before we replace alpha. 2013-12-03 00:51:25 +01:00
Henrik Rydgard
39b632b279 Copy the stencil value in REPLACE mode to fragment alpha (but only when it's safe) 
This is cheap but incomplete.
To do it more "right", we need multipass when blending or alpha test is enabled, ugh. That's for later.

Anyway, this improves the glow situation in Wipeout somewhat. Still lots of stuff that glows that shouldn't, but a little less overwhelmingly bright.

4352d720d8 Let's not use #define in GLSL ES shaders.

2c56ccef18 Make sure frag shader ID matches generated code. 
Before, we would use an id with alphatest on, but not actually compile in
alphatest.  Or, we would use a shader with alphatest, when we actually
could compile it out.

bf59f3db73 Add ugly hack setting for PowerVR to disable alpha test 
Causes glitches but the speedup is truly massive in some games so I relent :/

Please do not report graphics bugs when this is enabled...

Future: Maybe remove this setting except on PowerVR?

dcc63fd716 PowerVR: work around what appears to be a driver bug with equality test + discard, but not completely sure that discard isn't just broken. 
If this change breaks something, it was probably already broken, and it's PVR-only.

711d3ff52c Speedup a few 2D games on mobile by eliminating the alpha test in some conditions 
That is, if there's no depth testing/writing, and the alpha equation will produce the same result as the alpha test (when the alpha test is >= 0 or != 0 and the blend func is safe), we turn off the alpha test.
 2013-08-27 21:48:03 +02:00
Henrik Rydgard
6360fcb0ae Add some stats to get some idea of much alpha tested drawing we do. 
Turns out it's one hell of a lot and we really should fix this by
checking both vertices and textures to deduce when we can just skip
alpha testing safely, probably quite often.

I care about this because alpha testing drawing is very expensive
on some mobile chips.
