- Renormalizes arbitrary N-bit values as 8-bit normalized.
- NV hardware performs integer normalization at 8 bits if the size is less than 8.
- This can cause significant arithmetic drift because the error is multiplied by a huge number when sampling.
- Uncacheable resources can be reused as soon as they're made visible to the draw call.
- Since they're likely to be reused every draw call until the shader changes, it is important to reuse as much as possible
- Separate displayed statistics from actual backend statistics.
Allows asynchronous flipping to work correctly as it just uses display stats.
The real stats are used by the frame scope marker to determine behavior like engaging the FIFO optimizer or skipping draw calls correctly.
- Fix reading of varying registers in FP
Different registers have different behavior
- Always write to varying registers. If a register is not written to, it is initialized to (0, 0, 0, 1)
- Reimplements two-sided lighting correctly without hacks
- Also bumps shader cache version
- Do not allow offloader to handle its own faults. Serialize them on RSX instead.
This approach introduces a GPU race condition that should be avoided with improved synchronization.
- TODO: Use proper GPU-side synchronization to avoid this situation
- Properly commit orphaned blocks not invalidating existing cache structures
- Do not ignore overwritten objects when commiting as unprotected fbo. Avoids stale references to invalidated surface objects.
- Implements render target data load (aka Read Color Buffer/Read Depth Buffer)
- Refactors vulkan surface barrier to be much cleaner.
- Removes redundant surface barrier invocations after doing a merged load
from surface cache.
- Adds explicit access modes when gathering surfaces from cache.
- Further improve aliased data preservation by unconditionally scanning.
Its is possible for cache aliasing to occur when doing memory split.
- Also sets up for RCB/RDB implementation
vkAcquireNextImageKHR can also return VK_SUBOPTIMAL_KHR and is non-fatal.
However, it's a good idea to still recreate the swap chain later to maintain
optimal presentation paths after temporary occlusion.
- ZCULL queue was updated to one-per-cb but the conditional render sync hint was not updated.
- Do not unconditionally flush the queue unless the upcoming ref is contained in the active CB.
- This avoids spamming queue flush, which frees up resources and improves performance
- Merge viewport raster window and scissor into one clipping region
- Viewport raster clip is different from viewport geometry clipping in
hardware as the latter is configurable separately
- Tagged eventIDs can be used to safely delete resources that are no
longer used
- TODO: Expand gc to collect images as well
- TODO: Fix the texture cache to avoid over-allocating image resources
- Fix a typo in OpenAL
- Fix typo in cellHttp.h
- Unused variables in catch
- Use 64-bit shifts
- Use use_count with shared pointers, unique is depracated and getting removed
- Explicitly cast boolean to int
- Signed/unsigned issues with loop variables
- Fix missing return statement (the code path is unreachable, but compiler wants a return)
- */ ouside of comment
- Fix duplicate layout name
- Do not consume a slot every draw call, instead batch as many draws as possible
- Since renderpasses are dispatched per-draw-clause, keeping occlusion queries outside the renderpasses works fine
- If renderpasses are reorganized, occlusion tasks will have to be reorganized again
- Remove string comparisons from the hot-path!
- Use attribute streaming and push constants to avoid forcing a descriptor block copy every other draw call/pass.
While this isn't so bad on nvidia cards, it makes AMD cards a slideshow.
- When multithreaded RSX is enabled, the vertex cache just lowers performance
- The small cost of upload is paid by the asynchronous thread, allowing RSX to work optimally
- Refactor overlays and resolve passes to support use of push constants instead of relying buffer map/unmap
- Add support for nvidia resolve (NV is the only vendor not supporting shader_stencil_export)
