Instead of recreating the buffer view every single time the
underlying buffer gets invalidated, this keeps all buffer
views around until the object itself gets destroyed.
With this new approach, descriptor pools are decoupled from the
command list they are used with. Instead, the DXVK context takes
ownership of a single descriptor pool until it runs out of memory.
This reduces the amount of memory wasted for under-utilized pools
and should this reduce an application's memory footprint.
Improves performance because GCC generates silly code around those
if blocks, most of which have a false condition anyway. Improves
performance of 100k empty draw calls with no state changes by as
much as 25%.
This is identical to what the D3D11 function did, but having it in this
place will allow us to potentially implement better flush heuristics
based on work done on the CS thread.
While this doesn't support vertex stages yet, it should be faster
when the pipeline writes to storage resources from the fragment
shader.
We should analyze the vertex stage shaders for SSBO writes in
order to determine whether to spill the render pass.
Begins transform feedback when rendering with an xfb-enabled
pipeline bound, and ends transform feedback as needed, while
writing back the counters supplied by the app. This does not
yet support transform feedback queries or the draw command.
Introduces an OpenGL-style bind point for the argument buffer, which
means we can avoid a lot of unnecessary reference tracking in games
that do a lot of indirect draw calls.
Reduces CPU overhead in Assassin's Creed Odyssey.
This is optimized to allow a large number of indirect draws to be
submitted if they all access the same argument buffer, as is the
case in Assassin's Creed Syndicate and Odyssey.
The stat counter struct no longer has to be passed to
the pipeline compiler function.
The new implementation uses atomic counters of the pipeline manager
rather than per-command list counters, which removes the need to
pass the counter structure to the compiler function.
These new methods can support overlapped subresource copies by
creating a temporary resource and effectively using two copy
operations. This is required for D3D11 overlapped copies.
We don't support rasterization with a sample count different from
the framebuffer sample count, but if there are no attachments, any
sample count is allowed.
