d82ec339ee Remove the DisableShaderCache setting, rename the other 2018-12-15 10:44:05 +01:00

25b2ba013b VK: Add INI options to disable some vendor checks, and to disable the shader cache. 2018-12-11 00:36:15 +01:00

9a7ee41191 Vulkan: Avoid OpKill workaround with no stencil. 
It seems like depth gets messed up either way on discard, but behaves
sorta better without the write to depth.

5975f471e2 Vulkan: Only apply the depth workaround on Qualcomm devices (adreno) 
We've seen issues, and the validation layer still doesn't like them very much...

022670d882 GPU: Apply fog before color test. 
Hardware tests confirm the fog result is what's color tested.

8eb011c22d GPU: Clamp after color doubling. 
This is needed for blending to be correct - it blends a clamped value.

5ad948df73 Vulkan: Avoid discard when we can blend. 
Where possible, replace alpha and color testing with a zero alpha value.

This allows early fragment tests more often, which may help #11227.  It
may also generally help performance on PowerVR devices.

06340bfa9c Vulkan: Workaround Adreno discard bug. (#11197) 
This also explicitly enables early fragment tests when possible.  Using
conversative depth still works on Adreno and should allow some depth
optimizations.

011e57c0e7 Always specify GLSL version 450 when compiling Vulkan shaders. 
Bit of a risky change so late in the game but it's wrong, it needs fixing.
See for example the comments to fb7a63bd11

ed52d9f9fb Shader depal (VUlkan): Apply a half-texel offset when bilinear filtering, fixing #11008 
Also skip three texture samples if all indices are equal.

1888d828ec Vulkan: Workaround for bug in Adreno shader compiler affecting color tests. 
This comparison should pretty much work as well as the old one, I
believe, if not faster.

Should help #10695

496b2bff35 Vulkan: Fix fragment depth rounding. 
Was slightly off in the accurate depth path.

4731a2918c GPU: Use more typesafe shader IDs. 
Since they really are fairly distinct, let's make sure we can't mix them
accidentally.
