FSR (FidelityFX Super Resolution)
AMD's upscaling technology that renders games at a lower internal resolution and reconstructs a sharper image, boosting frame rate on handheld APUs.
FidelityFX Super Resolution (FSR) is AMD's answer to NVIDIA's DLSS: it renders a game at a lower internal resolution, then uses an algorithm to reconstruct a higher-resolution image, trading a small amount of visual fidelity for a meaningful frame-rate boost. Because handheld APUs have far less raw graphics power than a desktop GPU, FSR is often the difference between a game running smoothly and struggling to hold a playable frame rate.
Newer FSR versions (FSR 3 and the machine-learning-based FSR 4) add frame generation and improved image reconstruction, though the most advanced modes are typically limited to the newest, most capable APUs. FSR is GPU-agnostic and works on non-AMD hardware too, unlike DLSS which is NVIDIA-exclusive, which matters little on handhelds since almost all of them use AMD graphics anyway.
Why it matters when buying
FSR support is effectively universal across 2026 AMD-powered handhelds, so the real question is how well each game implements it, not whether the device supports it. Combining FSR with a lower TDP mode and VRR is one of the most effective ways to stretch battery life without sacrificing playability.
