The latest version of the Beetle PSX HW and RetroArch core. When using Beetle PSX HW, the MDEC Filter option, which is exclusive to the Vulkan renderer, does not work. Video in games is not smoothed and the MSAA parameter does not work, there is no anti-aliasing on 3d objects. The vulkan renderer is enabled in the settings. Please tell me how to fix this.
the MDEC filtering option is very subtle. It basically just gets rid of some of the color issues that happen due to RGB <-> YUV conversion.
From reading the core description of the Beetle PSX HW and other users reporting it should smooth out videos. Whether this feature is enabled or disabled does nothing for emulator. In addition, the inclusion of the MSAA function also does nothing.
