AMD’s FidelityFX Super Resolution 4 (FSR 4) has been confined to a select group of titles launched alongside the Radeon RX 9000-series GPUs, limiting its adoption among the broader gaming community.

The bottom of the FSR 4 slide says: "AMD FSR 4 upgrade feature only available on AMD Radeon RX 9070 series graphics for supported games with AMD FSR 3.1 already integrated." So, an "upgrade feature." ...

AMD has a new Radeon driver out, along with an updated FSR Technical Preview driver that expands its list of games supporting the frame rate-boosting Fidelity FX Super Resolution 4 (FSR 4 ...

You can assess the quality of FSR 4 yourself via the embedded video below, where Digital Foundry stacks up the new upscaler against the non-ML FSR 3.1, along with DLSS 3.7 and DLSS 4.0.

FSR 4 reportedly uses a machine learning algorithm based on 8-bit floating-point calculations. This necessitates support for WMMA (Wave Matrix Multiply Accumulate), which enables such precision.

AMD FSR 4 is set arrive alongside the first RDNA 4 GPUs, the Radeon RX 9070 XT and 9070. And this time it's going to be AI-powered.

Sony and AMD's collaboration for developing the FSR 4 ML-based upscaler is also going to benefit PlayStation customers. Sony is working on porting the tech over to its latest console.
