d9e543fdd2 Reduce PowerVR blockiness problems on older GPU revisions. #7153 #7150 2014-12-15 01:16:07 +01:00
Henrik Rydgard
f424bf73ae GLES: Implement a custom modulo function for PowerVR. Fixes blockiness, see #7153 and #7150 2014-12-14 20:59:21 +01:00

b4b7cd0722 GLES: Merge the two ShaderID classes as they are identical. 
I don't expect the number of bits required to grow or shrink massively for either type of shader in this backend.

c88b66b308 d3d9: Emulate some logic ops with blending. 
This makes Brave Story's intro visible.  Also add for GLES2/GLES3, but
doesn't seem to work on GLES2.

9af40cb14f d3d: Update the texture cache to mostly match. 
Now we can reduce the differences down.

04147827ee Account for texel offsets in the frag test lookup. 
Darn, thought this wouldn't be necessary but it is is for 1/255 and other
values.

Without cache:
PowerVR: temp, add, mul, fract, mul, compare
Other: mul, add, floor, compare

With cache: mul, add, texture lookup, compare

94c1271761 Add an experiment with using a texture for tests. 
Using an option for now so it's easy to test, if it works well we can
maybe remove the option.

de2c951665 Detect EXT_gpu_shader4 to use bitwise ops pre-3.3. 
This may allow it to work on more cards, and should fix a (probably driver
bug) error we've had reported in GL 3.0 / GLSL 1.3.

7f61da2e5a Add a hack for Silent Hill games. 
Either way has different problems, but it sounds like this will work
better for Silent Hill.  Probably still rendering wrong, unfortunately.

a43c3771a3 More correctly blend when hitting the frame cap. 
If we hit too many blits per frame, fall back correctly in the shader.

422db25277 Optimize fixed color blending that isn't blending. 
Gods Eater Burst uses this, for example.

b79e4d22b8 Improve a possible obscure blend mode. 
Seems like this would be likely to get overlap problems.

Unknown W. Brackets
0904085eb5 Avoid using fbo copies for the common 2a + 1-2a. 
We won't even get it right that often since the copy doesn't deal with
overlap properly.

44620c92ed Premultiply for doubled alpha blending if possible. 
This makes the effect more accurate where the values were being clamped
before.  Some obscure methods of blending may be slower.

4a8d52ab1a Add a config option for the slow framebuf effects. 
Like cluts, blitting, etc.  At higher render resolutions these are
expensive, and on some mobile devices they may be too much.

Of course, they're only used when needed so this is a speedhack.

61ea20875c Fix shader blending on ARM GLES3 devices. 
We currently ban them from GLES3, and this was interacting with that
incorrectly.  Should we still ban them, though?

17f5acd8b0 Support more src alpha doubling modes. 
These prevent the need for more blits.

143ad92afd Convert blending to doubling in more cases. 
We're not doubling the alpha, so all these cases are safe regardless of
the alpha value.

982f0416a2 Pre-mask alphatest value as a small optimization.
