Based on the register of the ASTC implementation from Ameerj (yuzu), currently our conversion from ASTC on Desktop tends to duplicates the unpacking of ASTC converted textures, leading to bad performance; since there are some graphical effects that actually access on the band of 32bits (RGAF32) than the common 16bits (RGAF16) from our ASTC path decoding method, which commonly uses ARGB8 (degradation -> LDR) transformation to reduce the memory cost per conversion; meanwhile it could actually provide initially better performance; the engine tended to get stalled when this writted stage effect got skipped; mostly because CPU tends to look for an unimplemented texture/ format query (from which doesn't exist on our MaxwellToVK); unlike what's commonly believed HDR was a format to write enviroment effects even before their appearance on video output (since Switch doesn't have HDR, only SDR on certain engines). The test result on this PR showed games like Astral Chain and other heavy reliant on ASTC decoding improved their performance and stability by around 15%; meanwhile could it be tied to a hardware gain, it's clearly a gain for direct access on what's required on most games. This PR also contains few Vulkan bug fix I encountered along this implementation. Special Thanks: -> Mr. Smoly Gidolard (@gidoly) Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/4190
Eden
Eden is a free and opensource (FOSS) Switch 1 emulator, derived from Yuzu and Sudachi - started by developer Camille LaVey. It's written in C++ with portability in mind, with builds for Windows, Linux, macOS, Android, FreeBSD and more.

Compatibility
The emulator is capable of running most commercial games at full speed, provided you meet the necessary hardware requirements.
A list of supported games will be available in future. Please be patient.
Check out our website for the latest news on exciting features, monthly progress reports, and more!
Development
Most of the development happens on our Git server. It is also where our central repository is hosted. For development discussions, please join us on Discord or Stoat. You can also follow us on X (Twitter) for updates and announcements.
If you would like to contribute, we are open to new developers and pull requests. Please ensure that your work is of a high standard and properly documented. You can also contact any of the developers on Discord or Stoat to learn more about the current state of the emulator.
