Resolution Scaling

The measured frame rates show a clear and predictable scaling pattern as resolution increases, but the rate of that scaling reveals where the bottleneck sits. At 1080p with Low settings, the combo produces 104 FPS. Moving to 1440p Low drops that to 82 FPS, a reduction of roughly 21%. Going from 1440p to 4K Low yields 58.4 FPS, another drop of about 29%. The fact that the 1440p-to-4K penalty is larger than the 1080p-to-1440p penalty indicates that pixel throughput is becoming an increasingly dominant factor at higher resolutions.

The High preset tells a similar story but with a different starting point. At 1080p High, the system manages 60.7 FPS. At 1440p High, it falls to 48.7 FPS, a 19.8% decline. At 4K High, it sinks to 35.5 FPS, another 27.1% reduction. The Ultra preset follows the same pattern: 55.8 FPS at 1080p, 46.4 FPS at 1440p, and 36.4 FPS at 4K. The consistency of these percentage drops across presets suggests that the scaling behavior is resolution-bound rather than settings-bound.

The data indicates that this combination of the Intel Core i5-14400F and the AMD Radeon RX 7600 XT is GPU-limited at higher resolutions. At 1080p Low, the 104 FPS figure suggests the CPU can feed frames quickly, but as resolution climbs, the GPU's shading workload grows faster than the CPU's frame preparation work. The 4K Ultra result of 36.4 FPS is not far above the 4K High result of 35.5 FPS, implying that beyond a certain point, additional settings overhead has diminishing impact because the GPU is already saturated. The gap between Low and Ultra at 4K is 22 FPS, whereas at 1080p that same gap is 48.2 FPS — a strong indicator that the GPU becomes the limiting component well before 4K.

CPU Role

The Intel Core i5-14400F brings 10 cores and 16 threads to the simulation, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. In synthetic benchmarks, this processor achieves a Cinebench R23 multicore score of 21914 and a single-core score of 3093. The Geekbench results show 11209 multicore and 2333 single-core. These figures position the CPU in the 88th percentile versus all CPUs, with an average benchmark score of 32508.

The nearest rivals in synthetic performance are tightly clustered. The Intel Core i7-12800H scores 32513, a delta of 0%. The AMD Ryzen 5 PRO 7645 scores 32446, a delta of 0.2% (slightly behind). The AMD Ryzen 7 250 scores 32584, a delta of -0.2% (slightly ahead). The Intel Core i7-13705H scores 32586, also a delta of -0.2%. This grouping means that, from a pure compute standpoint, the i5-14400F is effectively interchangeable with these four rivals in CPU-bound workloads.

For Microsoft Flight Simulator, the CPU's role is primarily about maintaining a consistent frame delivery floor. The game simulates weather, physics, and AI traffic, which creates bursts of single-threaded work. The 4.70 GHz boost clock is relevant here, as higher single-thread performance directly translates to fewer frame-time spikes. The data supports this: at 1080p Low, the system reaches 104 FPS, which is a CPU-friendly scenario where the simulation logic is the main constraint. At 1080p Ultra, the drop to 55.8 FPS is not proportional to the settings increase alone; it reflects the GPU beginning to struggle with the added rendering load. The CPU's 88th percentile ranking suggests it will not be the primary limiter in most configurations, but the 65 W TDP and locked multiplier indicate it is designed for sustained, efficient operation rather than extreme overclocking headroom.

Settings Recommendations

The measured rows provide a clear hierarchy for balancing image quality against frame rate. At 1080p, the Medium preset delivers 81.4 FPS, which is a 34.1% improvement over High's 60.7 FPS and a 45.9% improvement over Ultra's 55.8 FPS. The jump from Low to Medium costs 22.6 FPS (from 104 to 81.4), but the visual uplift from Low to Medium in a flight simulator is substantial — terrain detail, object density, and shadow quality all improve. For smooth flight at 1080p, Medium is the sweet spot, as it maintains a comfortable margin above 60 FPS while avoiding the steep drop to High and Ultra.

At 1440p, the choices become more constrained. Medium produces 66.2 FPS, which is playable but not silky. High drops to 48.7 FPS, and Ultra to 46.4 FPS. The data suggests that 1440p Medium is the only preset that keeps the experience above the 60 FPS threshold, and even then only barely. For users who prioritize frame rate over maximum fidelity, 1440p Low at 82 FPS offers a large performance buffer, but this preset likely sacrifices too much visual detail for a simulator that relies on visual immersion.

At 4K, the situation is more difficult. The best result is Low at 58.4 FPS, which is just shy of 60. Medium yields 45.4 FPS, High 35.5 FPS, and Ultra 36.4 FPS. The 4K Ultra result is actually higher than 4K High by 0.9 FPS, which is within measurement noise but suggests that the Ultra preset does not impose a meaningful additional burden over High at this resolution. For 4K users, the recommendation is clear: use Low if you want near-60 FPS, or accept Medium at 45.4 FPS if you need more detail. Anything above Medium at 4K results in a sub-40 FPS experience, which is likely too choppy for most flight simulation scenarios.

GPU Role

The AMD Radeon RX 7600 XT is built on the RDNA 3.0 architecture with the Navi 33 chip, fabricated on a 6 nm process at TSMC with 13,300 million transistors. The GPU operates with a base clock of 1980 MHz, a game clock of 2470 MHz, and a boost clock of 2755 MHz. It carries 16 GB of GDDR6 memory on a 128-bit bus, yielding a bandwidth of 288.0 GB/s. The memory runs at 2250 MHz, which translates to 18 Gbps effective.

The GPU's synthetic benchmark results paint a picture of a mid-range part. It achieves a Passmark G3D score of 17132, a Geekbench OpenCL score of 83114, and a Geekbench Vulkan score of 88301. The 3DMark Steel Nomad DX12 score is 2348. Its percentile ranking versus all GPUs is 63rd, with an average benchmark score of 20146. The nearest rivals in synthetic benchmarks are tightly packed: the AMD Radeon RX 460 scores 20088 (0.3% ahead), the AMD Radeon RX 7600 scores 20258 (0.6% behind), the NVIDIA GeForce RTX 2060 SUPER scores 19774 (1.9% ahead), and the NVIDIA GeForce RTX 3070 Mobile scores 20534 (1.9% behind).

In the context of Microsoft Flight Simulator, the GPU's role is decisive at higher resolutions. The measured data shows that at 1080p, the GPU can handle the rendering load across all presets, with even Ultra producing 55.8 FPS. However, at 1440p and especially 4K, the GPU's 128-bit memory bus and 288.0 GB/s bandwidth become limiting factors. The 16 GB frame buffer is ample for this game's textures, but the bandwidth constraint explains why the FPS drops so steeply when pixel count rises. The RX 7600 XT's performance relative to the RX 7600 (0.6% delta) suggests that the extra 8 GB of VRAM (16 GB vs the standard 8 GB) does not translate into a meaningful FPS advantage in this title, which is likely more bandwidth-bound than capacity-bound at high resolutions.

Measured FPS Breakdown

At 1920x1080, the system delivers its strongest results. Low settings produce 104 FPS, Medium drops to 81.4 FPS, High falls to 60.7 FPS, and Ultra bottoms out at 55.8 FPS. The progression is smooth, with each preset step costing roughly 20 FPS except the final step from High to Ultra, which costs only 4.9 FPS.

At 2560x1440, the frame rates compress. Low yields 82 FPS, Medium 66.2 FPS, High 48.7 FPS, and Ultra 46.4 FPS. The gap between High and Ultra narrows to just 2.3 FPS, suggesting that the Ultra preset at 1440p adds minimal visual overhead relative to High.

At 3840x2160, the results are the most constrained. Low reaches 58.4 FPS, Medium falls to 45.4 FPS, High drops to 35.5 FPS, and Ultra sits at 36.4 FPS. The anomaly where Ultra (36.4 FPS) slightly outperforms High (35.5 FPS) is noteworthy, though the 0.9 FPS difference is within typical measurement variance. The overall pattern across all resolutions shows that the Low-to-Medium step is the most efficient trade-off, while the High-to-Ultra step provides diminishing returns, particularly at higher resolutions. The combo's rank in this game is 1184 out of 1795 tested combinations, placing it in the lower-middle tier for this specific title.
