move ui loop out of hw/pvr
vk: implement multi-rendering, delay swap. Load fb before render pass
fps counter now counts frames, not renders
vk: force ignoreTexAlpha for 565 texture in case the supporting texture
has an alpha channel (RTT). Fixes Alone in the Dark cinematic scenes.
pvr: better detection of frame swapping (FB_R_SOF/FB_W_SOF)
pvr: synchronous rendering now always waits for render in progress
(speed measurement not reliable, render skipped when multi-rendering)
vk: limit swap chain size to 2
Linear tiling is faster for small, frequently updated textures
When lots of textures are updated each frame, a skipped frame will
destroy/recreate all textures, causing another skipped frame, etc. So
in-flight texture tracking is disabled, except for RTT textures
Limit swap chain to 2 images
Refactor base and oit renderers to avoid code dup
Keep in-use imave and image views when the texture is updated.
Fix inside clipping (18 wheeler rear mirror)
Wait until the graphics queue is idle before changing shared buffers and
attachments.
Refactoring
fetch color format, storage buffer alignment and stores/atomics support
at init
support for framebuffers used as input attachments
use Allocator instead of VulkanAllocator
return handles instead of unique handles
store texture in the cache map instead of the heap
make related functions member of the class (CollectCleanup, killtex ->
Clear)
refactor common OSD stuff into rend/osd
vulkan support for OSD
Try to find an optimal depth format then fall back to linear
Use same depth format for rtt depth attachments
Allow RenderToTextureBuffer setting to be changed at runtime
Enable vulkan on windows
align uniform buffers according to physical device requirements
destroy old swap chain before creating new one
some drivers don't support some 16-bit texture formats for optimal
tiling
Transition images back to transfer and update them instead of
deleting/recreating.
Keep track of in-flight texture command buffers and free them when idle.
