Allow _volatile to be set from MultiRegionHandle checks again

4

Tracking handles have a `_volatile` flag which indicates that the resource being tracked is modified every time it is used under a new sequence number. This is used to reduce...

GPU: Don't trigger uploads for redundant buffer updates

7

Benefits: - Reduces number of buffer uploads greatly in certain games (4096 byte cost each time) - Avoids splitting render pass on Vulkan (cost depends on GPU driver) - Batches...

GPU: Eliminate CB0 accesses when storage buffer accesses are resolved

4

The zeroth constant is typically used by official drivers as a kind of "driver support buffer". Command buffers/macros load draw parameters in this buffer for the shader to use with...

Gpu: Fix thread safety of ReregisterRanges

1

A quick fix to prevent reading the wrong value of Count when reregistering ranges for a new target buffer. Buffer flushes from another thread can modify the range list when...

GPU: Periodically clear volatile flags

3

Buffer tracking handles have an optimisation where they can be set as _volatile, which means that we assume the data is always modified. This avoids the cost of setting and...

GPU: Track buffer migrations and flush source on incomplete copy

2

Makes sure that the modified range list is always from the latest iteration of the buffer, and flushes earlier iterations of a buffer if the data has not been migrated...

UI: Add Metal surface creation for MoltenVK

2

Depends on (includes) #3818. This PR adds metal surface creation, and a bunch of other UI changes. There is a basic change to the Vulkan project to allow games to...

GPU: Use lazy checks for specialization state

1

This PR adds a new class, the SpecializationStateUpdater, that allows elements of specialization state to be updated individually, and signal the state is checked when it changes between draws, instead...

GPU: Swap bindings array instead of copying

2

Reduces work on UpdateShaderState. Now the cost is a few reference moves for arrays (for stages with bindings), rather than copying data. Cached bindings arrays are created when shaders are...

Shader: Add fallback for LDG from "ube" buffer ranges

5

We have a conversion from LDG on the compute shader to a special constant buffer binding that's used to exceed hardware limits on compute, but it was only running if...
