Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear and consistent scaling pattern as resolution increases. At 1080p with Ultra settings, this combination produces 107 FPS, but stepping up to 1440p drops that to 88.7 FPS, and 4K Ultra falls further to 61 FPS. That represents a 43% reduction from 1080p to 4K on Ultra settings, which is a substantial performance cost. The pattern is similar across all quality presets: Low settings show 193.5 FPS at 1080p, 156.9 FPS at 1440p, and 114.1 FPS at 4K — a 41% drop from the lowest to highest resolution.

This scaling behavior tells a specific story about where the bottleneck lies. The FPS penalty from 1080p to 1440p is proportionally larger than the penalty from 1440p to 4K in most cases. For example, on High settings, the drop from 1080p (116.5 FPS) to 1440p (93.3 FPS) is a 20% reduction, while the drop from 1440p to 4K (65.5 FPS) is a 30% reduction. The fact that the 4K penalty is more severe suggests the GPU is becoming increasingly stressed at higher pixel counts, which is typical for a flight simulator with complex scenery rendering.

The data implies that the RTX 4070 Ti SUPER is the dominant limiting factor at 4K, but at 1080p, the CPU still has headroom to push higher frame rates. The gap between Low and Ultra at 1080p is 86.5 FPS (from 193.5 down to 107), which indicates the GPU is doing heavy lifting even at lower resolutions. However, the 20-core Intel Core i7-14700K with its 5.60 GHz boost clock is evidently capable of feeding the GPU adequately at 1080p, as the FPS does not collapse to a CPU-bound plateau. The scaling pattern points to a balanced system at 1080p and 1440p, with the GPU becoming the clear constraint only when reaching 4K.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4070 Ti SUPER brings 16 GB of GDDR6X memory with a 256-bit bus and 672.3 GB/s of bandwidth. For Microsoft Flight Simulator, which streams vast terrain and aircraft model data, this memory capacity and bandwidth are directly relevant to the measured results. The 4K Ultra result of 61 FPS suggests the GPU is processing a heavy load, and the 16 GB frame buffer likely prevents any memory-related stuttering that could occur with smaller VRAM pools. The memory clock runs at 1313 MHz with 21 Gbps effective speed, which supports the texture streaming demands of a flight sim.

The GPU's boost clock is 2610 MHz, with a base clock of 2340 MHz, built on the Ada Lovelace architecture with 8448 shading units. The 44.10 TFLOPS FP32 performance is substantial, and the 66 ray tracing cores and 264 tensor cores are present but less critical for this particular game, which relies more on traditional rasterization. The 285 W TDP and triple-slot cooler design indicate this is a high-power part, and the data shows it delivers accordingly — 4K Medium at 87.9 FPS is a playable result, while 1080p Low reaches 193.5 FPS, near the limit of many displays.

The GPU's percentile rank of 86 among all GPUs positions it as a strong performer, and its benchmark scores support this: 3DMark Steel Nomad DX12 at 5569 and Passmark G3D at 31811. The nearest rivals in the GPU benchmark data include the NVIDIA CMP 50HX at -0.7% delta and the Intel Arc A550M at -2.1%, which shows the RTX 4070 Ti SUPER sits close to those parts in synthetic tests, though the measured game FPS tells the real story. The 16 GB VRAM is particularly relevant for a game like Flight Simulator, where high-resolution textures for aircraft, airports, and terrain can consume memory rapidly, and the data shows no signs of VRAM throttling at any resolution.

FAQ

Settings Recommendations

The measured data provides clear guidance on which preset offers the best experience. At 1080p, Ultra delivers 107 FPS, which is above the typical 60 FPS target and smooth for a flight simulator. However, the jump from High (116.5 FPS) to Ultra (107 FPS) costs 9.5 FPS, a relatively small penalty for the visual upgrade. The Low preset at 193.5 FPS is excessive for most displays and sacrifices visual fidelity unnecessarily. For 1080p users, High strikes the best balance — it maintains 116.5 FPS, which is 9% faster than Ultra, while still providing a reasonable visual quality level.

At 1440p, the recommendation shifts to High as well. The High preset delivers 93.3 FPS, which is comfortably above 60 FPS and only 4.6 FPS less than Ultra's 88.7 FPS. The Medium preset at 119.8 FPS offers a 28% performance boost over High, but the visual compromise may not be worth it for a sim where terrain detail matters. The data suggests 1440p High is the sweet spot for this resolution, as it keeps the frame rate high while preserving the visual richness that Flight Simulator is known for.

At 4K, the situation changes. Ultra at 61 FPS is technically playable but leaves little headroom for complex scenery or weather effects. High at 65.5 FPS is only marginally better, while Medium at 87.9 FPS offers a 34% improvement over Ultra with a modest visual downgrade. The data recommends 4K Medium as the best experience — it provides a smooth frame rate that stays well above 60 FPS, and the visual difference between Medium and High is less critical in a sim where the view is often distant terrain. Low at 114.1 FPS is overkill for 4K and would sacrifice too much visual quality.

Measured FPS Breakdown

At 1920x1080, the combo produces a wide range of results depending on settings. Low settings achieve 193.5 FPS, Medium reaches 152.4 FPS, High delivers 116.5 FPS, and Ultra drops to 107 FPS. The scaling from Low to Ultra is a 44.7% reduction in FPS, which reflects the increasing GPU load from graphical effects and texture quality. The gap between High and Ultra is 9.5 FPS, the smallest step between any two consecutive settings at this resolution, suggesting diminishing returns from the highest preset.

At 2560x1440, the results are predictably lower. Low settings hit 156.9 FPS, Medium reaches 119.8 FPS, High delivers 93.3 FPS, and Ultra drops to 88.7 FPS. The reduction from 1080p to 1440p is 18.9% on Low (from 193.5 to 156.9), 21.4% on Medium (from 152.4 to 119.8), 19.9% on High (from 116.5 to 93.3), and 17.1% on Ultra (from 107 to 88.7). The relatively consistent percentage drop indicates the GPU is handling the pixel increase uniformly across settings.

At 3840x2160, the performance takes a more significant hit. Low settings produce 114.1 FPS, Medium reaches 87.9 FPS, High delivers 65.5 FPS, and Ultra drops to 61 FPS. The drop from 1440p to 4K is 27.3% on Low (from 156.9 to 114.1), 26.6% on Medium (from 119.8 to 87.9), 29.8% on High (from 93.3 to 65.5), and 31.2% on Ultra (from 88.7 to 61). The larger percentage drops at High and Ultra settings suggest that the combination of high resolution and high settings pushes the GPU to its limits, with 4K Ultra being the most demanding configuration at 61 FPS.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i7-14700K is a 20-core, 28-thread processor with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. Its Raptor Lake architecture includes 33 MB of shared L3 cache, and the CPU's benchmark results show strong multi-threaded performance: Cinebench R23 multi-core score of 44534 and Geekbench multi-core score of 18896. The single-thread performance is also notable, with a Cinebench R23 single-core score of 6287 and a Geekbench single-core score of 2932, which matters for a game like Flight Simulator that has significant single-threaded simulation logic.

The CPU's percentile rank of 96 among all CPUs places it in the top 4% of processors, and its average benchmark score of 70074 is nearly identical to the nearest rival, the Intel Core i7-14700KF at 70104 (0% delta). This close benchmark parity suggests the i7-14700K is a well-balanced part for gaming workloads. The 20 cores and 28 threads provide ample parallelism for the background tasks in a flight sim, such as terrain generation and AI traffic, while the high boost clock of 5.60 GHz handles the main simulation thread.

In the measured FPS data, the CPU's influence is most visible at 1080p Low, where the 193.5 FPS result indicates the GPU is not the limiting factor. At this setting, the CPU must feed frames quickly, and the 5.60 GHz boost clock enables the i7-14700K to keep up. However, as resolution increases and settings rise, the GPU becomes the bottleneck, and the CPU's role diminishes. The data shows that even at 4K Ultra, the CPU does not hold back the GPU, as the FPS scales predictably with resolution rather than collapsing due to CPU limitations. The 33 MB L3 cache and 28 threads provide sufficient headroom for the sim's complex world-streaming logic, ensuring that the CPU never becomes the primary constraint in this configuration.
