The Continent is calling again. With CD Projekt Red shifting to Unreal Engine 5, local gamers are already asking if their current rigs will survive the next chapter. If you are eyeing the RX 7800 XT The Witcher 4 Ultra Settings at 4K: FPS Results 2026 projections might surprise you. Before dropping your hard-earned ZAR on a new setup, let us look at exactly what to expect from this highly anticipated title.

Unreal Engine 5 Meets AMD Power ⚡

Unreal Engine 5 is undeniably heavy. Advanced features like Lumen global illumination and Nanite virtualised geometry demand serious pixel-pushing power. The Radeon RX 7800 XT is already known as an absolute beast for 1440p gaming... but 4K Ultra is another beast entirely.

When you browse our latest graphics cards, the 7800 XT stands out for its massive 16GB of VRAM. That memory buffer is a crucial specification for handling next-generation 4K textures. Without enough VRAM, modern open-world games stutter heavily. Thankfully, AMD gives you plenty of headroom to keep your gameplay smooth.

Projected Performance Numbers 🚀

Running native 4K Ultra in a 2026 release will likely crush most mid-to-high tier GPUs. We project native frame rates hovering around 30 to 40 FPS. That is certainly playable for a cinematic single-player RPG... but PC gamers usually want more fluidity.

With AMD FidelityFX Super Resolution (FSR) enabled, the story changes completely. FSR uses clever spatial upscaling to boost your frames without ruining image quality. With FSR set to Quality mode, you can expect a much smoother 60+ FPS experience. If you prefer a system ready to go right out of the box, our custom pre-built PC deals often pair this exact GPU with beefy Ryzen processors to prevent any annoying system bottlenecks.

TIP

Optimise Your FSR Settings 🔧

When playing heavy Unreal Engine 5 games at 4K, always set AMD FSR to 'Quality' mode. You get a massive frame rate boost while keeping the picture crisp enough to spot a monster in the swamp from a mile away.
