Joshua Ashton 58f25098a0 radv: Use TRUNC_COORD on samplers ... The default behaviour (0) is: "round-nearest-even to n.6 and drop fraction when point sampling" whereas the Vulkan spec simply wants us to floor it (1) "truncate when point sampling". See 15.6.1 in the Vulkan spec. https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#textures-normalized-operations The Direct3D spec also mandates this (https://microsoft.github.io/DirectX-Specs/d3d/archive/D3D11_3_FunctionalSpec.htm#7.18.7%20Point%20Sample%20Addressing) This fixes some point-sampling texture precision issues in some Direct3D 9 titles such as Guild Wars 2 and htoL#NiQ: The Firefly Diary that are not present on other vendors. Fixes dEQP-VK.pipeline.sampler.exact_sampling.* https://github.com/Joshua-Ashton/d9vk/issues/450 https://github.com/doitsujin/dxvk/issues/1433 CC: <mesa-stable@lists.freedesktop.org> Reviewed-by: Samuel Pitoiset <samuel.pitoiset@gmail.com> Reviewed-by: Bas Nieuwenhuizen <bas@basnieuwenhuizen.nl> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/3951>		2020-04-23 09:57:08 +00:00
