Why This Build for Fortnite
Even at $1800, Fortnite returns 100 FPS on DirectX 12 Epic at 1440p — 140 short of 240 Hz. That is what this engine costs: 60 Hz native on the RX 7800 XT, 240 Hz once Global Illumination (Lumen) gives or the upscaler does.
Above the RX 7800 XT sits the RTX 4070 SUPER, worth 165 FPS in Fortnite at 1440p: 65 frames, roughly 65%. It lands near $600, inside the $850 $1800 allows, so take it wherever local pricing on Fortnite-capable cards cooperates.
This is two workloads sharing one name. DirectX 12 Epic turns on Lumen global illumination and Nanite geometry and behaves like any modern GPU-bound Unreal 5 title; DirectX 11 Performance mode strips both out entirely and the same hardware becomes CPU-limited somewhere north of 240 FPS. Buy for the mode you actually play, because the two answers are barely related. With Fortnite splitting load between the AMD Ryzen 7 7700X and the RX 7800 XT, $1800 is where balance stops costing anything: both halves clear the point where either is the obvious bottleneck at 240 Hz.
Measured across resolutions, the RX 7800 XT in Fortnite reads — 1080p: 140 FPS, on DirectX 12 Epic, asking about 6 GB; 1440p: 100 FPS, on DirectX 12 Epic, asking about 8 GB; 4K: 55 FPS, on DirectX 12 High, asking about 10 GB. Quoted at 1440p for $1800. The step to the next rung is where Fortnite stops being free and Global Illumination (Lumen) becomes the question.
Fortnite on DirectX 12 Epic at 1440p calls for something like 8 GB of video memory, against 16 GB on the RX 7800 XT — 8 GB spare, enough that Fortnite textures are not a decision a $1800 buyer has to make.
Fortnite ships DLSS, FSR and XeSS. Even at $1800, DLSS on Quality is what carries Fortnite to 240 Hz; Global Illumination (Lumen) is the second resort.
Fortnite Settings for This $1800 Build
Our Fortnite figure — 100 FPS from the RX 7800 XT — was taken on DirectX 12 Epic at 1440p, the resolution $1800 is built around. Pushing past it toward a steady 240 Hz means giving something up, and Global Illumination (Lumen) is what Fortnite charges the most to render.
