- Avoid re-locking memory if there is no reason to do so (no draws issued)
- Actively bound regions should always get written to the backing cache
- Forcefully read memory during download if writes to the target have occured since last sync event
- Unroll main compute queue loop
- Do NOT run GPU cores on mappable memory! This has a dreadful impact on performance for obvious reasons
- Enable dynamic SSBO indexing (affects AMD)
- Make loop unrolling and loop length variable depending on hardware and find optimum
- Region pitch of 64 (disabled) can be used to indicate packed contents - do not assume it is the actual pitch!
- Also fixes interaction of AA factors with lockable_region size
- Use names for overlay command config and vertex data instead of std::pair.
- Make a couple of compiled_resource constructors explicitly named functions.
- Used to transfer D32S8 data where it makes sense to use this variant
- On nvidia cards, it is very slow to move aspects from D24S8 probably due to the format being faked.
For this reason, the unsafe variant is used for both D16 and D24S8 to avoid the heavy performance loss
- RADV does not keep a mapping ptr around for subsequent remap and falls back to heavy amdgpu methods every time
Explicitly manage pointer in the ring buffer structure to fix this
- 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
- Removes the old depth scaling using an overlay.
It was never going to work properly due to per-pixel stencil writes being unavailable
- TODO: Preserve stencil buffer during ARGB8->D32S8 shader conversion pass
- Some applications (e.g Backbreaker) use an evil hack to resolve MSAA.
The application respecifies a formerly AA region as a region with no AA then performs a framebuffer feedback lookup.
The old memory keeps AA during read, but writes back to itself with AA resolved.
This is evil on several levels but it just happens to work on PS3
