The Last of Us Part 1 (the remake of the original 2013 game, in the same engine of The Last of Us Part 2) was never one of the most well-optimized titles – there were plenty of complaints at the time it came out of how it regularly crashed and stuttered on some peoples’ systems, along with some bizarre/hilarious graphical bugs. The game has improved in this area since release however, and now those of us with Radeon graphics cards can rejoice, because the game now supports FSR 4! In other words – more performance for absolutely free.

You can read more about it, plus the other changes, in the v1.1.5 patch notes. There are a bunch of AMD sponsored games without FSR 4, but now The Last of Us Part 1 is no longer one of them. FSR 4 is only compatible with AMD’s latest RDNA 4 graphics cards – the RX 9070, 9070 XT, and 9060 XT.

What is FSR 4?

FidelityFX Super Resolution (FSR) 4 is AMD’s latest iteration of its upscaling technology, and it brings several significant improvements over FSR 3. While FSR 3 introduced frame generation alongside traditional spatial upscaling, FSR 4 refines this further by tightly integrating both processes with machine learning; this reduces latency and improves visual consistency between generated and native frames, helping to eliminate the jitter or ghosting seen in earlier implementations. The new ‘Fluid Motion’ also helps reduce perceived latency.

FSR 4 has better motion handling and less temporal flicker, meaning cleaner motion clarity and reduced artifacts like shimmering, especially during high-speed scenes or when displaying fine details such as foliage or text. While FSR has historically avoided machine learning to remain open and cross-platform, FSR 4 introduces optional AI-enhanced modules that can be enabled on GPUs that support them (particularly newer RDNA 3.5+ cards). These AI tools help improve edge reconstruction and texture detail preservation without compromising performance.

How does FSR 4 compare to DLSS 4?

FSR 4 basically sits somewhere between Nvidia’s DLSS 3 and 4 in terms of FPS performance and image quality, but has the benefit of not being tied to specific GPU hardware – any graphics card can use FSR, whereas DLSS is Nvidia only.
