From a34fb0e9392c59e5bd7a764b83f3460bf65b861b Mon Sep 17 00:00:00 2001 From: riperiperi Date: Sun, 26 Mar 2023 11:51:02 +0100 Subject: [PATCH] Vulkan: Insert barriers before clears (#4596) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Vulkan: Insert barriers before clears Newer NVIDIA GPUs seem to be able to start clearing render targets before the last rasterization task is completed, which can cause it to clear a texture while it is being sampled. This change adds a barrier from read to write when doing a clear, assuming it has been sampled in the past. It could be possible for this to be needed for sample into draw by some GPU, but it's not right now afaik. This should fix visual artifacts on newer NVIDIA GPUs and driver combos. Contrary to popular belief, Tetris® Effect: Connected is not affected. Testing welcome, hopefully should fix most cases of this and not cost too much performance. * Visual Studio Moment * Address feedback * Address Feedback 2 --- .../DescriptorSetUpdater.cs | 2 +- Ryujinx.Graphics.Vulkan/EnumConversion.cs | 2 +- Ryujinx.Graphics.Vulkan/FramebufferParams.cs | 18 +++++++ Ryujinx.Graphics.Vulkan/PipelineBase.cs | 4 ++ Ryujinx.Graphics.Vulkan/TextureStorage.cs | 54 +++++++++++-------- 5 files changed, 56 insertions(+), 24 deletions(-) diff --git a/Ryujinx.Graphics.Vulkan/DescriptorSetUpdater.cs b/Ryujinx.Graphics.Vulkan/DescriptorSetUpdater.cs index 7e126e04..ab3befd8 100644 --- a/Ryujinx.Graphics.Vulkan/DescriptorSetUpdater.cs +++ b/Ryujinx.Graphics.Vulkan/DescriptorSetUpdater.cs @@ -236,7 +236,7 @@ namespace Ryujinx.Graphics.Vulkan } else if (texture is TextureView view) { - view.Storage.InsertBarrier(cbs, AccessFlags.ShaderReadBit, stage.ConvertToPipelineStageFlags());
