Why This Build for Horizon Forbidden West
86 FPS on High at 1440p clears the 60 Hz Horizon Forbidden West is played at by 26. $1800 buys that margin rather than the average — the RX 7800 XT keeps Clouds at full value in the heaviest scenes, which is where Horizon Forbidden West actually costs you.
Above the RX 7800 XT sits the RTX 5070 TI, worth 116 FPS in Horizon Forbidden West at 1440p: 30 frames, roughly 35%. Street pricing settles that one. The $850 ceiling is what keeps $1800 balanced rather than a Horizon Forbidden West GPU bolted to a starved platform.
Decima renders the densest vegetation and the most expensive volumetric cloud simulation of any PlayStation port we benchmark, and the machines themselves are costly to draw — layered metal shaders with per-part destruction on each one. This is the heaviest of the four Sony ports at every resolution, and the one to size a graphics card against if you intend to play several of them. Horizon Forbidden West being GPU-bound is what justifies $850 of a $1800 budget in graphics. The AMD Ryzen 7 7700X is here to stay out of the way; past it, processor money stops showing up on screen.
Measured across resolutions, the RX 7800 XT in Horizon Forbidden West reads — 1080p: 110 FPS, on Very High, asking about 8 GB; 1440p: 86 FPS, on High, asking about 10 GB; 4K: 50 FPS, on High, asking about 12 GB. Quoted at 1440p for $1800. The step to the next rung is where Horizon Forbidden West stops being free and Clouds becomes the question.
Horizon Forbidden West on High at 1440p calls for something like 10 GB of video memory, against 16 GB on the RX 7800 XT — 6 GB spare, enough that Horizon Forbidden West textures are not a decision a $1800 buyer has to make.
Horizon Forbidden West ships DLSS, FSR and XeSS. At $1800 the native 86 stands on its own in Horizon Forbidden West; DLSS is what you keep back for a faster panel later.
