Making changes to ConfigManager.h has always been a pain, because
it means rebuilding half of Dolphin, since a lot of files depend on
and include this header.
However, it turns out some includes are unnecessary. This commit
removes ConfigManager includes from files which don't contain
SConfig or GPUDeterminismMode or GPU_DETERMINISM (which means the
ConfigManager include is not used).
(I've also had to get rid of some indirect includes.)
Note: It's not 100% perfect, as some of the GPU capablities leak into the
pixel shader UID.
Currently our UIDs don't get exported, so there is no issue. But someone
might want to fix this in the future.
As much as possible, the asserts have been moved out of the GetUID
function. But there are some places where asserts depend on variables
that aren't stored in the shader UID.
SSAA relies on MSAA being active to work. We only supports 4x SSAA while in fact you can enable SSAA at any MSAA level.
I even managed to run 64xMSAA + SSAA on my Quadro which made some pretty sleek looking games. They were very cinematic though.
With this, it properly fixes up SSAA and MSAA support in GLES as well. Before they were broken when stereo rendering was enabled.
Now in GLES they can properly support MSAA and also stereo rendering with MSAA enabled(with proper extensions).
OpenGL ES 3.2 adds this feature to core
It was available to GLES 3.1 as GL_{EXT, OES}_texture_buffer as well.
For the non-Nvidia vendors that implemented this is:
- Qualcomm's Adreno 4xx
- IMGTec's PowerVR Rogue
OpenGL ES 3.2 adds a few things we care about supporting in core. In particular:
- GL_{ARB,EXT,OES}_draw_elements_base_vertex
- KHR_Debug
- Sample Shading
- GL_{ARB,EXT,OES,NV}_copy_image
- Geometry shaders
- Geometry shader instancing (If they support GL_{EXT,OES}_geometry_point_size)
Nvidia was the first to release an OpenGL ES 3.2 driver which I uesd to test this on.
This also enables GS Instancing on GLES 3.1 hardware if it supports all of the required extensions.
I tried to change messages that contained instructions for users,
while avoiding messages that are so technical that most users
wouldn't understand them even if they were in the right language.
We are declaring we require ARB_shader_image_load_store in the shader, this isn't an extension on GLES because it is part of the GLSL ES 3.1 spec.
If we are running as GLES then just not put it in the shaders.
