Resolution Scaling

The measured FPS data reveals a clear and expected scaling pattern as resolution increases, but the magnitude of the drop tells a specific story about this combo. At 1080p with Ultra settings, the combo delivers 134.2 FPS. Moving to 1440p Ultra drops that to 86.4 FPS, a reduction of roughly 35%. Jumping to 4K Ultra further reduces performance to 41.4 FPS, which is only about 31% of the 1080p Ultra figure. This is a steep decline, indicating that the AMD Radeon RX 6750 XT is the primary limiting factor at higher resolutions.

The pattern is consistent across all settings. At Low settings, 1080p produces 284.6 FPS, while 1440p Low yields 178.2 FPS, and 4K Low drops to 92.9 FPS. The scaling from 1080p to 1440p at Low is a 37% drop, and from 1440p to 4K it is a 48% drop. This suggests that even at Low settings, the GPU's pixel throughput becomes a bottleneck as resolution climbs. The 4K High result of 43.9 FPS versus the 1440p High result of 86.8 FPS shows a nearly 50% reduction, reinforcing that the Radeon RX 6750 XT's 192-bit memory bus and 432.0 GB/s bandwidth are being saturated at 4K.

What is notable is the difference between Low and Ultra settings at each resolution. At 1080p, the gap is 284.6 FPS down to 134.2 FPS, a 53% reduction. At 4K, the gap is 92.9 FPS down to 41.4 FPS, a 55% reduction. The similar proportional drop across resolutions indicates that the GPU's compute units, 2560 shading units, are handling the increased settings load consistently. The data shows that for a smooth 60 FPS experience, 1440p Ultra is borderline at 86.4 FPS, but 4K Ultra at 41.4 FPS is below the threshold. This combo is best suited for 1080p and 1440p gaming, where it can hit high frame rates, whereas 4K requires dropping to Low settings to maintain playability.
