Resolution Scaling

The FPS scaling from 1080p to 4K reveals the system's bottleneck characteristics. At High settings, performance drops from 191 FPS at 1080p to 146 FPS at 1440p (a 45 FPS decrease) and further to 86 FPS at 4K (a 60 FPS decrease from 1440p). This represents a 55% reduction from 1080p to 4K, indicating strong GPU scaling.

The Low settings show a similar pattern: 233 FPS at 1080p drops to 205 FPS at 1440p (28 FPS decrease) and 148 FPS at 4K (57 FPS decrease from 1440p). The total reduction from 1080p Low to 4K Low is 85 FPS, or 36.5%.

Medium settings demonstrate the most linear scaling: 210 FPS at 1080p, 186 FPS at 1440p (24 FPS decrease), and 113 FPS at 4K (73 FPS decrease from 1440p). The 4K Medium frame rate is 53.8% of the 1080p Medium value.

Ultra settings show the steepest curve: 187 FPS at 1080p, 139 FPS at 1440p (48 FPS decrease), and 82 FPS at 4K (57 FPS decrease from 1440p). The 4K Ultra frame rate is 43.9% of the 1080p Ultra value.

The scaling pattern indicates that at 1080p, the CPU's single-thread performance (3,064 Geekbench single-core, 2,259 Cinebench R23 single-core) becomes a limiting factor, as frame rates across different settings remain relatively close (187-233 FPS). As resolution increases, the GPU's workload grows, and the RTX 5090's capabilities (104.8 TFLOPS FP32, 1.79 TB/s bandwidth) become the primary determinant of performance. The 4K results show a wider spread between settings, confirming the GPU-bound nature at higher resolutions.
