The RPCS3 team has announced that its Playstation 3 emulator now supports AMD’s FidelityFX Super Resolution. According to the team, the AMD FSR implementation works pretty well for almost every game, and is currently available only for Vulkan.
Do note that shimmering and swimming issues present in low-resolution upscales will remain in the upscaled image. Additionally, AMD FSR does not work with 3D output.
Lastly, the AMD FSR implementation in RPCS3 uses the FP32 fallback only.
“For some precision reasons, it is common to disable FP16 support as a workaround. If the overhead is deemed to be measurable, we can of course enable the FP16 fast path for this.”
