* During pipeline configure the function would acquire some payload space from the descriptor update queue,
write the descriptor data on the GPU thread and give the scheduler a pointer to the beginning of said space to update it later.
TickFrame resets the payload cursor, used to track acquires, back to the beginning of the buffer.
This wasn't a problem before since WaitWorker was called at the end of the frame but now it is.
If a frame writes to a cursor before the scheduler catches up, it will crash
* To fix this the payload buffer has been increased to account for the in flight frames that are allowed to exist now.
TickFrame will switch between the payload spaces instead of resetting
Intel's SPIR-V shader compiler is broken. For now, skip compiling any compute pipelines until they fix this issue.
This is not a perfect workaround, as there are a small subset of non-compute pipelines that still cause it to crash, but this should cover the majority of crashes.
It is unfortunate that even with a test case reported 6 months ago the issue has not been fixed in favor of fixing "the most popular games and apps".
Intel, you can do better than this.
On AMD a subpixel offset of 1/512 of the texel size is applied to the texture coordinates at a ImageGather call to ensure the rounding at the texel centers is done the same way as in Maxwell or other Nvidia architectures.
See https://www.reedbeta.com/blog/texture-gathers-and-coordinate-precision/ for more details why this might be necessary.
This should fix shadow artifacts at object edges in Zelda: Breath of the Wild (#9957, #6956).
Adds the PushModes Try and Wait to allow producers to specify how they want to push their data to the queue if the queue is full.
If the queue is full:
- Try will fail to push to the queue, returning false. Try only returns true if it successfully pushes to the queue. This may result in items not being pushed into the queue.
- Wait will wait until a slot is available to push to the queue, resulting in potential for deadlock if a consumer is not running.
