They're normally not hardware accelerated unless the device supports the `VK_QCOM_filter_cubic_weights` extension. The matrix weights are those matching [the specification itself](https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#VkSamplerCubicWeightsCreateInfoQCOM). +- **Spline-1**: Bicubic interpolation (similar to Mitchell) but with a faster texel fetch method. Generally less blurry than bicubic. +- **Gaussian**: Whole-area blur, an applied gaussian blur is done to the entire frame. +- **Lanczos**: An implementation using `a = 3` (49 texel fetches). Provides sharper edges but blurrier artifacts. +- **ScaleForce**: Experimental texture upscale method, see [ScaleFish](https://github.com/BreadFish64/ScaleFish). +- **FSR**: Uses AMD FidelityFX Super Resolution to enhance image quality. +- **Area**: Area interpolation (high kernel count). +- **MMPX**: Nearest-neighbour filter aimed at providing higher pixel-art quality. diff --git a/src/android/app/src/main/res/values/arrays.xml b/src/android/app/src/main/res/values/arrays.xml index fa9a02aead..86fae9ba3c 100644 --- a/src/android/app/src/main/res/values/arrays.xml +++ b/src/android/app/src/main/res/values/arrays.xml @@ -260,6 +260,7 @@ @string/scaling_filter_scale_force @string/scaling_filter_fsr @string/scaling_filter_area + @string/scaling_filter_mmpx @@ -275,6 +276,7 @@ 9 10 11 + 12 diff --git a/src/android/app/src/main/res/values/strings.xml b/src/android/app/src/main/res/values/strings.xml index 3a1e4bc924..a9707a15c7 100644 --- a/src/android/app/src/main/res/values/strings.xml +++ b/src/android/app/src/main/res/values/strings.xml @@ -1017,9 +1017,10 @@ ScaleForce AMD FidelityFX™ Super Resolution Area - Zero-Tangent-Cardinal + Zero-Tangent B-Spline - Mitchell-Netravali + Mitchell + MMPX None diff --git a/src/common/settings_enums.h b/src/common/settings_enums.h index 2a3116bcdf..8022d8216e 100644 --- a/src/common/settings_enums.h +++ b/src/common/settings_enums.h @@ -143,7 +143,7 @@ ENUM(ConfirmStop, Ask_Always, Ask_Based_On_Game, Ask_Never);
