Implement HLE macro for DrawElementsIndirect

15

This implements an HLE macro for the `DrawElementsIndirect` NVN macro, improving performance on games that uses this type of draw. This is mostly extracted from #3306. **Affected games:** Nier Automata:...

Use vector transform feedback outputs if possible

2

Currently, shaders with transform feedback use individual, per-component outputs. That's because each component might potentially have a different, non-sequential offset, and in those cases we might need to specify different...

Use a SSBO for the shader support buffer, if using UBOs would be above limit

5

APIs have a limit on the number of uniform buffers one can use on the shader. On NVIDIA OpenGL that is 14. The Switch GPU supports up to 18, but...

.NET 6/7 improvements

5

## Feature Request ### What feature are you suggesting? #### Overview: This is a short list of improvements that have been enabled by .NET 6 or .NET 7, with the...

Remove shader dependency on SPV_KHR_shader_ballot and SPV_KHR_subgroup_vote extensions

1

This replaces the use of those two extensions with equivalent functionality that is supported on "base" SPIR-V and does not require any extension. This is more widely supported and required...

Ensure that vertex attribute buffer index is valid on GPU

1

Some games will have vertex attributes with a invalid buffer index (the vertex buffer doesn't exist). This is invalid and may cause crashes on both on OpenGL and Vulkan depending...

Use vector outputs for texture operations

1

This changes allows the number of texture operations to be greatly reduced in most shaders that accesses textures. Before we would generate one texture operation per component that is accessed,...

Allow SNorm buffer texture formats on Vulkan

1

For some reason, OpenGL does not allow SNorm formats to be used with buffer textures (at least on NVIDIA), so this workaround was added where it uses a signed integer...

Implement non-MS to MS copies with draws

1

This implements the non-multisample to multisample copies using draws on Vulkan. This is required because the Apple Silicon GPU does not support image load or store to multisample images. The...

Restrict shader storage buffer search when match fails

1

Right now, when the match for storage buffer fails, we generate code to check the current address against the address for all possible 16 storage buffers until we find a...
