Releases: gfx-rs/portability
Support VK_KHR_portability_subset
New swapchain model
The main feature (or anti-feature) of the release is the completely new swapchain model. See PR #210 for more info. TL;DR: it's smooth and fast, much better suited to Metal and D3D, but it's not compatible with some obscure use cases. So it either works great, or it doesn't work at all, which is arguably an improvement from the previous "mostly sometimes works". One of the side effects, for example, is proper fullscreen support.
As always, there are many correctness fixes, including (but not limited to):
- image clears
- border color support
- added more limits that were missing
- support for
VK_KHR_get_surface_capabilities2
The highlight app of this release is Filament compatibility. It is a real-time physically based rendering engine from Google:
Events support
We've done a number of binding model improvements, added support for VkEvent as well as experimented with Metal Argument Buffers (available behind GFX_METAL_ARGUMENTS env var, not ready for wide usage yet). In terms of applications, we have gzDoom running with a minor tweak to WSI:
