From 484eb645ae0611f60fae845ed011ed6115352e06 Mon Sep 17 00:00:00 2001 From: riperiperi Date: Tue, 7 Jul 2020 03:41:07 +0100 Subject: Implement Zero-Configuration Resolution Scaling (#1365) * Initial implementation of Render Target Scaling Works with most games I have. No GUI option right now, it is hardcoded. Missing handling for texelFetch operation. * Realtime Configuration, refactoring. * texelFetch scaling on fragment shader (WIP) * Improve Shader-Side changes. * Fix potential crash when no color/depth bound * Workaround random uses of textures in compute. This was blacklisting textures in a few games despite causing no bugs. Will eventually add full support so this doesn't break anything. * Fix scales oscillating when changing between non-native scales. * Scaled textures on compute, cleanup, lazier uniform update. * Cleanup. * Fix stupidity * Address Thog Feedback. * Cover most of GDK's feedback (two comments remain) * Fix bad rename * Move IsDepthStencil to FormatExtensions, add docs. * Fix default config, square texture detection. * Three final fixes: - Nearest copy when texture is integer format. - Texture2D -> Texture3D copy correctly blacklists the texture before trying an unscaled copy (caused driver error) - Discount small textures. * Remove scale threshold. Not needed right now - we'll see if we run into problems. * All CPU modification blacklists scale. * Fix comment. --- .../CodeGen/Glsl/HelperFunctions/TexelFetchScale_cp.glsl | 7 +++++++ .../CodeGen/Glsl/HelperFunctions/TexelFetchScale_fp.glsl | 11 +++++++++++ 2 files changed, 18 insertions(+) create mode 100644 Ryujinx.Graphics.Shader/CodeGen/Glsl/HelperFunctions/TexelFetchScale_cp.glsl create mode 100644 Ryujinx.Graphics.Shader/CodeGen/Glsl/HelperFunctions/TexelFetchScale_fp.glsl (limited to 'Ryujinx.Graphics.Shader/CodeGen/Glsl/HelperFunctions') diff --git a/Ryujinx.Graphics.Shader/CodeGen/Glsl/HelperFunctions/TexelFetchScale_cp.glsl b/Ryujinx.Graphics.Shader/CodeGen/Glsl/HelperFunctions/TexelFetchScale_cp.glsl new file mode 100644 index 00000000..381566d3 --- /dev/null +++ b/Ryujinx.Graphics.Shader/CodeGen/Glsl/HelperFunctions/TexelFetchScale_cp.glsl @@ -0,0 +1,7 @@ +ivec2 Helper_TexelFetchScale(ivec2 inputVec, int samplerIndex) { + float scale = cp_renderScale[samplerIndex]; + if (scale == 1.0) { + return inputVec; + } + return ivec2(vec2(inputVec) * scale); +} \ No newline at end of file diff --git a/Ryujinx.Graphics.Shader/CodeGen/Glsl/HelperFunctions/TexelFetchScale_fp.glsl b/Ryujinx.Graphics.Shader/CodeGen/Glsl/HelperFunctions/TexelFetchScale_fp.glsl new file mode 100644 index 00000000..4efaa65a --- /dev/null +++ b/Ryujinx.Graphics.Shader/CodeGen/Glsl/HelperFunctions/TexelFetchScale_fp.glsl @@ -0,0 +1,11 @@ +ivec2 Helper_TexelFetchScale(ivec2 inputVec, int samplerIndex) { + float scale = fp_renderScale[1 + samplerIndex]; + if (scale == 1.0) { + return inputVec; + } + if (scale < 0.0) { // If less than 0, try interpolate between texels by using the screen position. + return ivec2(vec2(inputVec) * (-scale) + mod(gl_FragCoord.xy, -scale)); + } else { + return ivec2(vec2(inputVec) * scale); + } +} \ No newline at end of file -- cgit v1.2.3
