  "message": "D3D11: Cache last created SRV and RTV in the Texture class.\n\nIt\u0027s a common scenario that users create a texture\u0027s view transiently\nonce per frame and never cache it.\ne.g:\nvoid renderStep() {\n    // Create a view and attach it to a render pass.\n    wgpu::RenderPassDescriptor renderPassDesc \u003d ...;\n    renderPassDesc.colorAttachments[0].view \u003d texture.CreateView();\n\n    // Draw the render pass.\n}\n\nIn this case, D3D11 has to repeatedly re-create the texture\u0027s D3D native\nview every frame. This is not a cheap operation. Unlike metal backend,\nwhere the view creation could be skipped entirely in some simple\nscenarios:\nSee: https://source.chromium.org/chromium/chromium/src/+/main:third_party/dawn/src/dawn/native/metal/TextureMTL.mm;drc\u003d5ca64904963dc4676216ddfd226779522c271540;l\u003d104\n\nThis CL adds a small optimization for this scenario by:\n- Caching last created D3D views within the wgpu::Texture object.\n- Checking the cache for an existing D3D view before creating a new one\nwhen a wgpu::TextureView is initialized.\n\nBug: chromium:377716220\nBug: 409035452\nChange-Id: Id99c38f8c91dc441f9a6ba92ca888dea3e8d37dc\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/234254\nReviewed-by: Geoff Lang \u003cgeofflang@chromium.org\u003e\nReviewed-by: Corentin Wallez \u003ccwallez@chromium.org\u003e\nCommit-Queue: Quyen Le \u003clehoangquyen@chromium.org\u003e\n",
