Since we create only one DxvkContext per D3D11Device, rather than
per D3D11DeviceContext as originally planned, there is no need to
keep the pipeline manager as a global thread-safe object. This may
slightly reduce CPU overhead.
Reduces command submission overhead by reusing fence objects
instead of creating new ones for each submission. Improves
error reporting in case the submission cannot be complete.
* [util] Adds getTempDirectory() function
Will be used by on-disk pipeline caching
* [dxvk] Implement on-disk shader caching
Saving the pipeline cache to disk when the application exits
should be sufficient but the DxvkPipelineCache destructor isn't
reliably called on exit (ref-counting issue?).
As a workaround every frame we check and save the cache if the
size increased by some amount or after one minute elapsed.
* [dxvk] Periodically update shader cache file in separate thread
Reduces lock contention and slightly improves performance in games
that rely heavily on the buffer renaming mechanism if the lock
protecting the original free list was contested.
This is required for resource mapping on deferred contexts.
May also fix a potential synchronization issue where a buffer
could be mapped multiple times before the CS thread would mark
the physical buffer as used, which would result in invalid data.
Reduces the CPU overhead of descriptor set updates, which usually
happen once per draw call. Gains seem to be minor in most games,
some outliers show significantly better performance (i.e. Tomb Raider).
Closer to the D3D11 API. We cannot use the normal clearColorImage and
clearDepthStencilImage methods in case the game uses a 2D array view
for a 3D image. Fixes some validation issues in Hellblade.
SPIR-V tools did not turn out to be useful, but increased the
binary size by a significant amount and caused build problems.
- spirv-opt: Far too slow for the intended purpose, and Nvidia
specific shader issues have been reported and fixed.
- spirv-val: Not much value in practice since shaders can be
written to a directory and validated manually.
* Add Custom PCI Vendor and Device ID Support
Allow the user to configure DXVK to use a custom PCI Vendor and Device ID, so that the program behaves the same on different cards.
* Remove AMD/NVIDIA/INTEL Shortcuts
* Remove extra semicolon
* Return DxvkGpuVendor to being an enum class
* Fixed hexadecimal output
Improves overall frame rate and latency in situations where the
application's render thread cannot keep up with the CS thread.
Considerable frametime improvements in NieR:Automata and
slightly higher frame rates in The Witcher 3.

vkGetQueryPoolResults may never return if VK_QUERY_RESULT_WAIT_BIT is
set, and may return queries as not available when they should in fact
be available. This would cause indefinite hangs, so instead we return
fake data to query objects if retrieving query data fails.
