Microsoft Flight Simulator

Microsoft Flight Simulator places extraordinary demands on both processor and graphics hardware, and the measured results for the Intel Core i5-14400F paired with the NVIDIA GeForce GTX 1650 illustrate a system that is fundamentally constrained by its GPU. The data across all resolutions and presets shows a configuration capable of producing playable frame rates only at its lowest settings, with the gap between Low and every other preset widening as resolution increases. This analysis examines the measured FPS rows to determine the optimal settings, contextualize the performance against other tested combinations, and isolate the roles of the CPU and GPU in shaping the experience.

Settings Recommendations

The benchmark data is unambiguous: the Low preset is the only viable path to a smooth experience with this hardware combination. At 1920x1080, the Low preset delivers an average of 49.4 FPS, which is the only measured configuration to approach the 60 FPS target commonly associated with fluid simulation. The Medium preset at the same resolution drops to 39.9 FPS, a 19% reduction, while High falls further to 28.8 FPS and Ultra bottoms out at 26.6 FPS. For a flight simulator where camera panning and terrain streaming demand consistent frame pacing, the 49.4 FPS figure on Low is clearly the most playable.

The recommendation to stay on Low becomes even more critical at higher resolutions. At 2560x1440, the Low preset produces 39.4 FPS, which is still marginally playable, but Medium drops to 33.1 FPS and both High and Ultra fall below 23 FPS. At 3840x2160, no preset achieves even 31 FPS; Low manages 30.1 FPS, Medium 24.0 FPS, High 17.1 FPS, and Ultra 18.6 FPS. The pattern is consistent: each step up in quality costs a significant fraction of the frame rate, and the GPU's limited resources are best spent on resolution scaling rather than graphical fidelity.

Given that the GTX 1650 has 4 GB of VRAM, the data suggests that the Ultra preset's texture and shadow demands are not merely taxing but likely exceed the frame buffer's comfortable capacity, explaining why Ultra at 1080p (26.6 FPS) is actually slower than High at 1440p (22.0 FPS) by a smaller margin than expected. The optimal experience is therefore achieved by locking to 1080p with the Low preset, prioritizing a stable frame rate over visual enhancements. Users with variable refresh rate monitors could tolerate the 39.4 FPS at 1440p Low, but the 1080p Low setting remains the best balance of speed and responsiveness.

FAQ

Q: What is the best resolution and preset combination for this system?

A: The 1920x1080 Low preset yields the highest measured average at 49.4 FPS. All other presets at this resolution fall below 40 FPS, and every preset at higher resolutions produces averages of 39.4 FPS or lower.

Q: How much performance is lost when moving from Low to Medium at 1080p?

A: The average frame rate drops from 49.4 FPS to 39.9 FPS, a reduction of approximately 19%. This gap is consistent with the GPU being the primary bottleneck, as the settings increase shader and texture workloads.

Q: Is the GTX 1650 capable of running the Ultra preset at any resolution?

A: No. The highest Ultra average is 26.6 FPS at 1920x1080. At 2560x1440 and 3840x2160, Ultra averages fall to 22.1 FPS and 18.6 FPS respectively, making the preset unplayable.

Q: Does the CPU hold back performance in any measured configuration?

A: The data does not indicate CPU limitation. The Core i5-14400F has 10 cores and 16 threads with a boost clock of 4.70 GHz, and its benchmark percentile (88th) is high. The FPS scaling with resolution and settings points to the GPU as the limiting factor.

Q: How does the 4K Low preset compare to the 1080p Ultra preset?

A: The 4K Low average of 30.1 FPS is slightly higher than the 1080p Ultra average of 26.6 FPS. This suggests that the GPU can handle the pixel count at Low settings better than it can handle the increased shading complexity of Ultra at a lower resolution.

Q: What is the lowest measured frame rate among all configurations?

A: The 3840x2160 High preset produces the lowest average at 17.1 FPS. The 4K Ultra preset is marginally better at 18.6 FPS, indicating that the High preset's specific settings are particularly punishing for this GPU.

How This Combo Ranks

In the database of tested combinations for Microsoft Flight Simulator, this pairing of the Intel Core i5-14400F and NVIDIA GeForce GTX 1650 ranks 1687th out of 1795 tested combos. This places it in the bottom 6% of all configurations, which aligns with the measured frame rates that struggle to exceed 50 FPS at any setting. The rank reflects the substantial handicap of the GPU, as the CPU is far more capable relative to its peers. The i5-14400F sits in the 88th percentile among all CPUs, with an average benchmark score of 32508, nearly identical to its nearest rival, the Intel Core i7-12800H (32513, 0% delta). In contrast, the GTX 1650 sits in the 43rd percentile among all GPUs, with an average score of 8713, just 0.4% behind the NVIDIA GeForce RTX 3050 A Mobile (8746) and 0.5% ahead of the NVIDIA Quadro P2200 (8671).

The combination's low rank is a direct consequence of this mismatch. The CPU's headroom is wasted in this game, as the GPU cannot translate the processor's 21914 Cinebench R23 multi-core score into high frame rates. The data shows that even at 1080p Low, where the CPU has the least work relative to the GPU, the system only reaches 49.4 FPS. This suggests that the GTX 1650's 2.984 TFLOPS of FP32 performance and 128.1 GB/s of memory bandwidth are simply insufficient for Flight Simulator's dense rendering workload. Compared to other combos in the database, this rank indicates that users would need to drop resolution and settings aggressively to achieve playable performance, which is exactly what the measured FPS confirms.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a GPU-bound system with diminishing returns at higher pixel counts. At the Low preset, the averages progress from 49.4 FPS at 1920x1080 to 39.4 FPS at 2560x1440 to 30.1 FPS at 3840x2160. This represents a 20% drop from 1080p to 1440p, and a further 24% drop from 1440p to 4K. The scaling is roughly proportional to the pixel count increase (1.78x from 1080p to 1440p, 2.25x from 1440p to 4K), but the actual FPS reductions are smaller, indicating that the GPU is not purely pixel-bound but also benefits from the reduced CPU overhead at lower resolutions.

At the High preset, the scaling is steeper: 28.8 FPS at 1080p drops to 22.0 FPS at 1440p (a 24% reduction), then to 17.1 FPS at 4K (a 22% reduction). The Ultra preset shows a similar pattern, with 26.6 FPS at 1080p falling to 22.1 FPS at 1440p and 18.6 FPS at 4K. The fact that the Ultra preset's 4K average (18.6 FPS) is higher than High's 4K average (17.1 FPS) is an anomaly that suggests the High preset may have specific settings (perhaps anti-aliasing or shadow quality) that are disproportionately expensive at 4K. Overall, the resolution scaling data strongly indicates that the GTX 1650's 4 GB frame buffer and 128-bit memory bus are the limiting factors, as the performance drops are more pronounced when settings increase alongside resolution.

GPU Role

The NVIDIA GeForce GTX 1650 is a Turing-architecture GPU with 896 shading units, 56 texture mapping units, and 32 ROPs. Its base clock of 1485 MHz boosts to 1665 MHz, and the 4 GB of GDDR5 memory operates at 2001 MHz (8 Gbps effective) across a 128-bit bus, yielding 128.1 GB/s of bandwidth. In the context of Microsoft Flight Simulator, these specifications explain the measured FPS results. The 4 GB VRAM capacity is particularly relevant, as the game's high-resolution textures and terrain data can easily exceed this limit, forcing the GPU to swap data and causing the frame rate to collapse at Ultra settings.

The GPU's benchmark scores corroborate its modest standing. Its 3DMark Steel Nomad DX12 score of 305 and Passmark G3D score of 7880 place it in the 43rd percentile of all GPUs. The Passmark DirectX 11 score of 58 and DirectX 12 score of 35 highlight its weakness in modern API workloads, which is critical for Flight Simulator's DirectX 12 rendering path. The texture rate of 93.24 GTexel/s and pixel rate of 53.28 GPixel/s are low by today's standards, explaining why the game's dense scenery and reflective surfaces cause such severe frame rate drops. The GPU's end-of-life production status and its position just 0.4% behind the RTX 3050 A Mobile in average score (8746 vs 8713) confirm that this is an entry-level part that is outclassed by the demands of this simulation. The data shows that the GTX 1650 is the clear bottleneck, as its performance ceiling is reached at 1080p Low, and any increase in settings or resolution results in a disproportionately large FPS penalty.

CPU Role

The Intel Core i5-14400F is a 10-core, 16-thread processor from the Raptor Lake Refresh generation, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. It features 20 MB of shared L3 cache and 1.25 MB of L2 cache per core, along with an 80 KB L1 cache per core. The CPU's benchmark results are impressive, with a Cinebench R23 multi-core score of 21914 and a single-core score of 3093, placing it in the 88th percentile of all CPUs. Its Passmark multi-thread score of 25783 and single-thread score of 3723 further indicate strong computational capability.

In Microsoft Flight Simulator, the CPU is responsible for physics calculations, flight dynamics, and the simulation of world data. Given the i5-14400F's high multi-core performance, it is unlikely to be the limiting factor in this system. The measured FPS scaling with resolution and settings points exclusively to the GPU. For example, at 1080p Low, the system achieves 49.4 FPS, but at 1080p Ultra it drops to 26.6 FPS, despite the CPU having to handle the same simulation workload. This indicates that the CPU has ample headroom to feed the GPU, but the GTX 1650 cannot process the increased graphical load.

The CPU's nearest rival in benchmark scores is the Intel Core i7-12800H (32513 average, 0% delta), and the AMD Ryzen 5 PRO 7645 (32446, 0.2% delta), showing that the i5-14400F is competitively positioned among mid-range processors. However, this strength is irrelevant to the game's outcome when paired with a GPU that ranks only in the 43rd percentile. The data suggests that for this specific game, the CPU's 10 cores and 16 threads are sufficient to maintain frame pacing, but the GPU's limitations prevent the system from taking advantage of the CPU's performance. The processor's 65 W TDP and support for DDR4 and DDR5 memory are secondary factors; the core takeaway is that the CPU is not the bottleneck, and any performance improvements would require a GPU upgrade rather than a processor replacement.
