<member name="rendering/textures/vram_compression/compress_with_gpu" type="bool" setter="" getter="" default="true">
If [code]true[/code], the texture importer will utilize the GPU for compressing textures, improving the import time of large images.
[b]Note:[/b] This setting requires either Vulkan or D3D12 available as a rendering backend.
[b]Note:[/b] Currently this only affects BC1 and BC6H compression, which are used on Desktop and Console for fully opaque and HDR images respectively.
[b]Note:[/b] This only functions on a device which supports either Vulkan, D3D12, or Metal available as a rendering backend.
[b]Note:[/b] Currently this only affects certain compressed formats (BC1, BC4, and BC6), all of which are exclusive to desktop platforms and consoles.

<member name="rendering/textures/vram_compression/import_etc2_astc" type="bool" setter="" getter="" default="false">
If [code]true[/code], the texture importer will import VRAM-compressed textures using the Ericsson Texture Compression 2 algorithm for lower quality textures and normal maps and Adaptable Scalable Texture Compression algorithm for high quality textures (in 4×4 block size).
