- For some reason this has a massive impact on performance above some arbitrary threshold of calls
Shows up under surface_cache::get_merged_memory_region when doing gathers.
- Specifically fixes a corner case where double transforms are required.
Technically this can be made more readable using transformation matrices:
* M1 = transform_virtual_to_physical()
* M2 = transform_image_to_virtual()
* M3 = M1 * M2
* Result = Input * M3
But we don't use a CPU-side matrix library and it is not reasonable to do this on the GPU.
Depending on the dpi settings, the debug overlay was almost unreadable.
I also took the liberty to refactor some redundant client size calls and to add some margin to the left of the debug text.
- Transfer writes are expected to clobber surface cache contents. Do NOT reload from CPU memory for writes.
- TODO: During transfer write to surface cache objects, lock memory if it was unlocked to avoid silly problems.
- Do not allocate too many objects. This is a problem in games using dynamic memory allocators that can make it rare for a surface to fall on the same address twice, keeping zombie RTVs and DSVs alive much longer than needed.
- Current limit used is 256M of virtual VRAM which is impossible on retail PS3
- Adds support for partial (letterboxed) source images by taking insets
into account.
- Bugfix for potential access violation when capturing screenshot on
vulkan
