Microsoft Flight Simulator

Microsoft Flight Simulator pairs a 14-core Intel Core i5-14600KF with a 4 GB NVIDIA GeForce GTX 1650, producing a combination that is heavily constrained by its graphics subsystem. The benchmark data shows a processor that ranks in the 93rd percentile among all CPUs, paired with a GPU that sits in the 43rd percentile, and the measured frame rates reflect that imbalance across every resolution and settings preset.

Resolution Scaling

The frame rate drops from 1920x1080 to 3840x2160 are steep, and the pattern reveals a system that is almost entirely GPU-limited. At Low settings, the average FPS falls from 49.1 at 1080p to 39.3 at 1440p and then to 28.2 at 4K. That is a 57% reduction from 1080p to 4K, but the scaling is not linear — the 1440p result sits much closer to the 1080p figure than to the 4K figure, which suggests the GTX 1650's 128.1 GB/s of memory bandwidth and 4 GB frame buffer start to choke as pixel count rises.

The gap between Low and Ultra settings widens dramatically at higher resolutions. At 1080p, the spread between Low (49.1 FPS) and Ultra (29.1 FPS) is 20 FPS. At 1440p, that spread narrows to 18.2 FPS (39.3 vs 21.1). At 4K, the spread compresses to 11.1 FPS (28.2 vs 17.1). This compression indicates that at 4K, even the lowest settings cannot escape the GPU's fundamental throughput limits — the TU117 chip with 896 shading units and a 128-bit memory interface simply runs out of pixel pushing capability.

The 4K High preset delivers 15.3 FPS, which is below the 17.1 FPS of the Ultra preset at the same resolution. This anomaly suggests that the High preset may be engaging certain rendering paths that are particularly inefficient on this architecture, or that the memory pressure from the 4 GB GDDR5 buffer causes erratic behavior. The data shows 4K Medium (23.2 FPS) actually outperforms 4K High (15.3 FPS) by 8 FPS, which is a larger jump than the settings difference alone would explain.

CPU Role

The Intel Core i5-14600KF is a Raptor Lake-R part with 14 cores and 20 threads, boosting to 5.30 GHz. Its Cinebench R23 multi-core score of 32889 places it in the 93rd percentile of all CPUs, and its nearest rivals in the database are the Core i5-14600K (0.4% higher average score) and the AMD Ryzen 9 5950X (0.6% higher). The single-core performance is equally strong, with a Cinebench R23 single-core score of 4643 and a Geekbench single-core score of 2778.

For Microsoft Flight Simulator, which is known to be sensitive to single-threaded performance, this CPU should be more than adequate. The benchmark results confirm this: at 1080p Low, the system reaches 49.1 FPS, which is the highest average recorded in the entire dataset. Even at 4K Low, the 28.2 FPS result is nearly double the 4K Ultra figure of 17.1 FPS, showing that the CPU can feed the GPU with enough draw calls to keep it busy at lower settings.

The core count and 24 MB of shared L3 cache are not the limiting factors here. The PassMark multi-thread score of 38697 and the floating-point math score of 93048 indicate a processor that can handle the complex physics and flight modeling calculations this sim demands. The bottleneck is unequivocally the GPU: the GTX 1650's PassMark G3D score of 7880 places it in the 43rd percentile, and its nearest rivals include the Quadro P2200 (0.5% higher) and the Radeon 550X (0.4% higher) — all entry-level or older parts.

FAQ

Q: Why is the 4K High preset slower than 4K Ultra?

A: The data shows 4K High averaging 15.3 FPS while 4K Ultra averages 17.1 FPS. This inversion is unusual and likely stems from the GTX 1650's 4 GB memory buffer being overwhelmed by specific High preset rendering paths, causing a performance regression that does not appear at other resolutions.

Q: Can this combo run the game at 60 FPS?

A: No. The highest recorded average is 49.1 FPS at 1920x1080 with Low settings. Every other configuration falls below 40 FPS, and the 1080p Medium preset only reaches 34.7 FPS. The GTX 1650's 2.984 TFLOPS FP32 throughput is not sufficient for 60 FPS in this title.

Q: Is the CPU holding back the GPU?

A: No. The i5-14600KF has a 93rd percentile ranking and scores 32889 in Cinebench R23 multi-core. The frame rates scale directly with resolution and settings changes, which is the signature of a GPU-bound system. The CPU is not the limiting component in any measured configuration.

Q: What is the best playable setting for this combo?

A: 1080p Low at 49.1 FPS is the only configuration that approaches smooth playability. The 1440p Low preset at 39.3 FPS is usable, but 4K Low at 28.2 FPS and any Ultra preset below 30 FPS will feel stuttery in a flight simulator where smooth camera panning is critical.

Q: How does the GPU compare to its closest rivals?

A: The GTX 1650's average benchmark score is 8713, which is 0.4% lower than the RTX 3050 A Mobile and 0.4% lower than the Radeon 550X. It sits 0.5% above the Quadro P2200. All of these are within a 1% band, so the GPU is effectively average for its class.

Q: Does the 4 GB VRAM cause problems?

A: The data indicates yes. The 4K High preset (15.3 FPS) underperforms 4K Medium (23.2 FPS) by a wide margin, and 4K Ultra (17.1 FPS) is also below 4K Medium. This non-monotonic scaling is consistent with the 4 GB GDDR5 buffer being exhausted at higher settings, forcing the game to swap textures.

Measured FPS Breakdown

The complete dataset shows a clear hierarchy across all twelve measured configurations. At 1920x1080, the results are 49.1 FPS (Low), 34.7 FPS (Medium), 30.1 FPS (High), and 29.1 FPS (Ultra). The 15 FPS gap between Low and Medium is the largest single-step drop in the entire dataset, indicating that Medium settings engage significantly more GPU work than Low.

At 2560x1440, the figures drop to 39.3 FPS (Low), 32.6 FPS (Medium), 23.8 FPS (High), and 21.1 FPS (Ultra). The Medium preset at 1440p still delivers over 30 FPS, making it the second-most playable configuration after 1080p Low. High and Ultra both fall below 24 FPS, which is marginal for a simulator.

At 3840x2160, the results are 28.2 FPS (Low), 23.2 FPS (Medium), 15.3 FPS (High), and 17.1 FPS (Ultra). The 4K Medium score of 23.2 FPS is actually higher than the 4K High score of 15.3 FPS, a 7.9 FPS difference that cannot be explained by settings alone. The 4K Ultra result of 17.1 FPS also exceeds 4K High, reinforcing the idea that the High preset hits a pathological memory access pattern on this GPU.

The scaling efficiency across resolutions at Low settings is instructive: 1080p to 1440p costs 20% performance (49.1 to 39.3 FPS), while 1440p to 4K costs 28% (39.3 to 28.2 FPS). At Ultra settings, the drops are 27% (29.1 to 21.1 FPS) and 19% (21.1 to 17.1 FPS), respectively. The diminishing penalty at Ultra settings indicates that the GPU is already saturated at 1440p Ultra.

How This Combo Ranks

The combo ranks 1700 out of 1795 tested combinations in Microsoft Flight Simulator, placing it in the bottom 5% of all systems. This low ranking is directly attributable to the GPU: the CPU's 93rd percentile standing cannot compensate for a graphics card that sits in the 43rd percentile with a PassMark G3D score of 7880.

The rank of 1700 out of 1795 means that 95% of tested systems deliver higher average frame rates in this game. Even though the i5-14600KF is a top-tier processor by synthetic benchmarks — its nearest CPU rival, the EPYC 4345P, scores only 0.5% higher on average — the GTX 1650 is the weak link. The GPU's nearest rivals are all within 0.5% of its score, which means there is no headroom to be found in the graphics department.

In practical terms, this combo is only viable for low-resolution, low-settings play. The 1080p Low result of 49.1 FPS is the only configuration that approaches a smooth experience, and even that falls short of 60 FPS. For a flight simulator that renders dense terrain and detailed cockpits, the 4 GB VRAM and 128.1 GB/s bandwidth are severe constraints. The CPU has the single-thread muscle — a 4643 Cinebench R23 single-core score — to drive the simulation logic, but the GPU cannot keep up with the rendering demands at any resolution above 1080p Low.
