- Prefer lazy retire model. Sync commands are sent out and the reports will be
retired when they are available without forcing.
- To make this work with conditional rendering, hardware support is
required where the backend will automatically determine visibility by
itself during rendering.
- Sometimes program-point-size is enabled, but the vs does not actually
write to the point size register. In this case, pass the incoming point
size along instead of the default register init.
- Fix 2D coordinate sampling of W coordinate.
W is actually HPOS.w and not 1. Z is however always 0.
- Optimize register usage a bit
Disassembling compiled SPV shows that global declaration results in less ops than using inout modifiers. Modifiers generate extra mov instructions.
- 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
- 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.
- The hw generates inaccurate values when doing perspective-correct
interpolation of vertex output attributes and makes the comparison (a ==
b) fail even when they are a fixed constant value.
- Increase equality tolerance when doing comparisons in fragment
shaders for NV cards only to work around this issue.
- Teepo fix
- Index offset is ignored anyway and only used to calculate vertex attribute divisor index
- Specialized optimization for untouched xfer without primitive restart
- Compute is now used to assist in some parts of blit operations, since there are no format conversions with vulkan like OGL does
- TODO: Integrate this into all types of GPU memory conversion operations instead of downloading to CPU then converting
- Do not add unused subroutines in shaders unless necessary
-- makes shaders easier to read and disassembled spir-v has less clutter
- glsl: Replace switch block with lookup table
- The scale offset matrix is fine but on real hardware the z results seem to be independent of near/far clipping distances
-- If depth falls within near/far, clamp depth value to [0,1]
rsx/vk/shaders_cache: Move vp control mask to dynamic state
rsx/vk/gl: adds a shader cache for GL. Also Separates pipeline storage for each backend
rsx: Add more texture state variables to the cache
- Updates vulkan to use GPU vertex processing
- Rewrites vulkan to buffer entire frames and present when first available to avoid stalls
- Move more state into dynamic descriptors to reduce progam cache misses; Fix render pass conflicts before texture access
- Discards incomplete cb at destruction to avoid refs to destroyed objects
- Move set_viewport to the uninterruptible block before drawing in case cb is switched before we're ready
- Manage frame contexts separately for easier async frame management
- Avoid wasteful create-destroy cycles when sampling rtts
* Rework vertex attribute binding for vulkan. Allows always providing a buffer view to the pipeline even if the game has the attribute disabled as long as it is consumed by the vertex shader.
- Improvements to framebuffer usage; Avoid creating new resources every frame
- Handle null fragment program properly
- Collect vertex upload statistics
- vk: Pre-initialize 'unused' varying registers in the vertex shader in case it gets matched with a fs that consumes it
-- Fixes a crash about fog_c not being declared
gl/dx12/vk: Handle null fragment program
- cleanup - use yield semantic instead of sleep(0) as yield is more cross-platform
-- sleep(0) is a windows specific scheduler hint
* vk: fix separate front and back lighting
* vk: Inlined arrays can have emulated primitives too!
* vk: Use float input attribs for better compatibility
* vk: Free resources during shutdown
