    Phoronix: RadeonSI Gallium3D Driver Adds Sparse Texture Support For GFX9/Vega & Newer

    As one of the last major feature changes heading into Mesa Git this calendar year, RadeonSI Gallium3D as the open-source OpenGL driver for modern AMD Radeon GPUs there is now sparse texture support...

    I have Vega56, but which game uses this extension?

      Doom (2016) makes use of it. It is intended for virtual texturing (a.k.a. "megatexture"); where you stuff many/all your textures into one large texture, and transform the texture coordinates when loading geometry, or in the vertex shader. Sparse textures are useful when the virtual size of a texture is larger than you want to upload during a single frame, or when the used parts of the texture atlas are an awkward shape (i.e. all across the top of a square atlas).

      Of course, in the case of Doom (2016), you'd already be using the equivalent with the Vulkan renderer.

        Does the Vulkan renderer support this even for Polaris?

          I'm not sure, but I recall someone mentioning that it uses sparse binding; I would assume Polaris supports that but I'm not running any Polaris cards anymore to check.
